How to make a Dead Space helmet/costume?

Hi, I want to make the costume from the video game Dead Space. I want it to be durable, and good quality, but not too expensive. I would like to ask for some hints, as to what materials to use. What would be the best and the easiest material. Also, Im starting with the helmet, in case it will turn out to be too expensive, ill just stick with that and make the rest of the suit on another occasion. thank you for all your help ****note about the picture***** my helmet will have a blue film instead of the mesh and will light up like in the game. also, i plan on installing two pc fans into it, for ventilation.

Dead Drop at Instructables in SF? Answered

If you don't know what a dead drop is, it is a USB device mounted in a wall, in a public space where anyone can access it. Anyways, I have heard there is one at the the Instructables HQ in San Francisco. Is it still there, and does anyone know what's on it? Next time I am in San Francisco I will have to check it out!  

Question by your dog  


How or where do I buy/make a Dead Space Costume Easy and Cheap?

Okay, so lately I have been on a Dead Space rant. I really, really want to make a Dead Space Costume that looks like Isaac's, that or buy one, but I can't find one anywhere that is for sale, or any tutorials to make one. If you guys could please post a link to where I can buy one, or telling me how to make one, I would be over joyed with happiness (no joke, been looking FOREVER on how to buy/make one). So if you guys can help me that would be amazing. -lcarosella

Ancient technologies revisted - The space race

Back in the glory days of science we had the US, China and Russia competing and getting "out there" first.After WW2 finally ended we had the time and money to waste on humanity greatest challenge - getting a man safely onto the moon and back.The German space program had the advantage of a head start but Russia was not far behind.To show the world they mean business we got Sputnik.A tiny aluminium ball with a crappy battery emitting a "beep" from orbit.Nothing to be proud of if you actually think about it.However, it was a huge deal back then and a blow to the western world.The communists were faster...China was more modest and well, less successful at that time but it did not stop them.With Russia already announcing to get some animals up ther next the mighty US had to take a few shortcuts.It was no longer a race to get a human up there safely, it was only a race to somehow managed to get a man on the moon and back.The calculator your kid uses at school is more powerful than the "compters" used in the carfts for the Apollo program.Back then though it was top notch tech and deemed reliable....We already knew about the Van Allen belt and its deadly radiation levels.So you would think someone would have included this danger into the design...Assumption made in...It was assumed that the limited exposure time and some rudimentary "shielding" would be sufficient to protec the astronaut.Thankfully most of these assumtions turned out to be correct AFTER men made it through there in their tin cans.The step to send up a rocket with fancy equippment to do proper measurements and collect data about required shield material was simply skipped.A few weather balloon were tried though...Long story short, the race was over when the world listened to the famous words "A smal step for a man,but a giant leap for mankind."Russia continued for a while but losing the race meant those in charge decided it is no longer worth wasting money on.Shortly after the collapse followed in Russia.Why would the Russians give up so easy and why did China seemingly pull out of the race as well?Despite being "enemies" the old claim and goal was still valid - or was it?There was always that dream to go further out there once we made it to the moon.Build habitats on the moon so we can build ships and mine ressources.And for a while this dream was kept alive by the US.We went up there a few times, got complacent and even the public in theend failed to get hooked on the TV screen.Going to the moon and making it back alive was turning into a routine, nothing special anymore.Not even moon rocks could revive the public interest.It was costly as well....Officially the moon program ended for a long list of plausible reasons.What is striking though is that it ended rather aprupt and without warning so to say.We had rockets fully assembled, waiting to be used, we had space capsules and long lists of experiments tobe performed, we even included fancy equipment like a soloar powered transmitter supposed to constantly send seismic data and more back to earth.All this stuff never god used, was disamantled, deemed to be too expensive.Hold on a second here now....First millions are wasted to build a fancy rocket, more money is wasted to build new space capsules and landing equipment and then even more money is wasted on stff to get up there.It is then only logical to pull the plug without using any of it.....NASA abandoned projects before, including fully functional machines but they never wasted them like this.Some theorists claim the race to the moon was not about exploring the moon for our use once we actually made it up there.Their claim is that we found things that scared the US enough to never go up there again.These theorists got laughed at for decades, yes decades as their claims based on isider info are as old as the space race itself.Occupation is a word that you can use in many ways.Like occupying a land that you don't own but declare it yours anyways bacuase you are more powerful, more advanced than those you found on "your new land".Or like in deviding territories on a continent declared to be owned by no one - the Antartis.Officially this icy continent is free for everyone and every nation - the truth is far from it though.Same is true for our moon.It is devided and subdived to cater for eveyone making a claim.And to make a claim is simple; You go up there and leave something behind, then you state how much of the area you declare your so you can occupy and use it.Funny thing is that like in Antartica every is very strict and stays far away from the other fractions....The race is on again!!!For some it was a sudden announcement when we got to hear the US is planning and financing moon missions again.For others though it was a very predictable move.More and more private companies reach the point where they can afford to send someone to the moon at their cost without the need for taxpayer money.Commercial space flight is said to only be a few years away, mabe even sooner if SpaceX continues as planned.And "right on time" picures and videos are officially released by NASA to actually make it very plausible and almost undeniable that something or someone else it already out there.Including videos that seem to show creature living in the dead vacuum of space.But why not just relax and sit back like they did with commercial space flight?Give someone a few million and technical guidance but don't waste real money on it...Well, you can't really enforce to stay in control of everything, especially when it comes to the moon, if it is not your program.Once the testing is done your pilots are out, your crews are out and a private company is in control...So what is it on the moon the US is so desperate to get first hand experience on?The first few moon missions were mostly a prove of concept, later NASA used rovers to explore the areas around the landing sites, installed mirros to perform laser measurements from earth...The took sample, drilled into the ground and every now and then saw flying objects flying past, watching them.Like the Foo Fighters during WW2 they were like small spheres and extremely quick.Nothing to worry though as NASA knew about them for a long time, harmless little things....The story got a twist when the landing site for one mission had to abandoned.The astronaut appearently reported they were being "bullied" by Foo fighters and will try to land on the beta landing coordinates.It was enough to justify to check if there might e someone or something on the moon already.After all it could be unwise to do the same as what was done when Amrica was "found" by Columbus...And so some sesmic equippment was transported up there.Orginal intent was get seismic data from small metorites hitting the moon to determin the risk factor.Dropping the launch stage back onto the moon was meant as a test for the equipment and it dropped relatively close to the seismograph.What was observed came as a shock to those analysing the data - the damn thing is faulty!So during the next mission the data was checked again, with the same result.But it was also finally confirmed the results are correct as a second device gave the exact same seismic readings.What happened??Whenever something big and heavy dropped back onto the moon it started ringing like a bell for hours....And although never openly admitted, these finding actually pulled the plug on the moon program.Unofficially and if you trust the clue we got from former astronauts the bullying intensified with every mission.Some went as far as saying they did not feel welcome up there - go figure...NASA first tried to just cover it all up.A few years later they got more serious and tried to come up with plasusible explanations once it was claer evidence from these seismic reading somehow leaked out into the public.We got presented everything from the moon being made from some granite like and very hard rock.Nicely explains the ringing but not why it is did not crumble to dust from all the meteorites hitting it.We also got the explanation that the moon only has a very tough outer shell, possibly formed by the impact of the meteorites.And the list went on and on...Finally some outsiders took a decent look on the data, did good calculations and computer simulations basd on the fact that the moon for whatever reasson has no rotation as it should have.Their findings clearly state the moon is a mostly hollow sphere with much more mass on the side facing us.Based on the frequency and amplitude recrded during these events the sphere HAS TO BE made out of some high strenght metal.NASA made it a priority to ridicule this theory and over the years more and more reputable scientists jumped in as well.No matter what though they all failed to provide real evidence that the hollow moon theory is flawed - the data just speaks the truth.At least it was accomplished that the theory was forgotten and everyone could move on.Until more NASA evidence was leaked to outsiders.During one mission it was attempted to drill into the center of a crater and the results were the same as claimed during probe explorations done recently by china - first a thin layer of compressed rock, then metal, then nothing....Today you will find hollow moon data on official NASA servers available to everyone....And it all became available to be found right after it was declared "We are going back up there again!"The thing the press overlloked when this statement was made was what followed after "We have to"....Just think about it for while....NASA delevoped all sorts of prototypes and wasted billions to create fancy space crafts and drive systems.But start the next race to the moon once more with old and conventional rockets....Not because we are unable to come up with alternative lauch methods, we already developed them and computer simulations show us they would work perfectly at a fraction of the costs for a big rocket.Not because there wouldn't be money for alternatives either.Only because we suddenly no longer have the time to build and ready the alternatives ;)Almost 80 years with no interest, no funding, no plans.Then, within less then 3 months of work and decision making the race is on and more important than ever - WHY???We wanted to be able to fly like the birds since the dawn of time.We did it eventually.We wanted to fly faster and higher and we again did just that.We never stopped, we alway came up with new ways to make us fly and do safer than ever before.We did the same for the space race for a short while only.We settled for having a fancy space station close to home instead...Our urge to reach the stars is coded into our genes, we just need to somehow get closer and closer to them.But every time we get close to fullfilling this dream we pull the plug.If we can build and maintain a space station in orbit how hard would it be to assemble a space craft in orbit?According to those who planned and often protyped theise toys no big deal at all as it was already integrated into the design.We could have a little fleet of crafts up there already using the space stion as a "home base" when required and fueling up from the rich Helium3 deposites the moon is claimed to have.We did not do any of it, we entirely stopped the concept, the planning - again I aks you why....Once you figured out what really is so important about our moon you know why the space race seems to have stopped with the end of the Apollo program. You also figure out why we now have to go back up there.What you won't find out (yet) is what is really up there and how it got there.

A sight for international skywatchers - "Ring of Fire" Eclipse

From SpaceWeather.com:SOLAR ECLIPSE: On Monday, Jan. 26th, the Moon will pass in front of the sun producing an annular "ring of fire" eclipse. This is not a total eclipse; the Moon will cover only 93% of the sun's surface. Nevertheless, the Moon's dead-center transit across the solar disk will produce a sight of rare beauty for observers along the "path of annularity." Best views are to be had from islands in Indonesia where the ring of fire will appear to sink into the ocean at sunset. Meanwhile, in Australia, southeast Asia, southern parts of India and South Africa, observers will experience an off-center partial eclipse. Crescent-shaped sunbeams will dapple the ground while high overhead the Moon takes a curved bite out of the sun. Please visit http://spaceweather.com for eclipse maps, timetables and photos.If you're in the areas where the eclipse can be seen, how about taking and posting pictures?Animated map of eclipsePDF map of eclipse

Anyone know where to buy some really cheap USB flash drives or MicroSD cards?

Frenzy's instructable on USB dead drops got me inspired, but I don't want to set up just one!  I'd like to set up several around my little town here, and I don't want to break the bank doing it.  Does anyone know where to buy maybe six to twelve thumb drives or micro SD cards for super cheap?  I don't need anything particularly fancy, I'm sure 512mb or 1gb would be plenty of space.  I found some stuff on ebay but I'd still be paying around $35 for 10, and I'd like to get that down around $2 each or less.  What do you think?  Pipe dream or do you have some ideas?

Food Creator and dispensor

This project is currently in the research stage. Having been reading the books 'Zero to Maker' by David Lang (OpenROV) and 'The Toaster Project' by Thomas Thwaites I have realised what I need is a project with a goal to take me out of the Arduino blinky light and solder kit zone, in to real making/hacking. Lang suggests an 'Unknown Project' which as I understand it is one that has been unexplored or under-explored, and he also suggests that using a popular forum to log, share and discus ideas would help the process along. So my idea, is an open hardware food creating machine, that will produce a large array of food, from a limited array of ingredients (approx 50) that can be made easily, and a ingredient markup language. 3d food printers in current development are either impractical or unappealing to me. They range from candy makers, ones that still need to be hand finished and cooked or the one publicised for receiving NASA funding recently used dead bugs. They seem all to focus on the gimmick, and not the food, and I like food. The other approach is the barbots, which seem to mostly perform flawlessly, but are unable to produce food. So my approach is to work through the process logically and break it down to sub projects. Design meals by hand using the limited ingredients for proof of concept, choose the ingredients to provide the widest possible range of nutrients and transpose the recipies to psudocode that can be easilly transformed in to a markup language later. Design a process for mixing and cooking ingredients. I envision a system of different food processors, steamers, boilers etc. and a range of extruding dies. Design a self cleaning system. Possibly ultrasonic or ionic. To that end, here is my preliminary list of ingredients. sugar, salt, oil, water, co2,Alcohol 37.5%,pectin,bicarb,nutritional yeast coffee,tea,mint,cocoa,garlic,oregano,chilli powder, paprika rice,soya,corn,wheat lemon extract,orange extract,tomato powder,dried apple,dried carrots,dried peas,potato powder. These ingredients can be used to make among other things, sausages, burgers, curry's, pasta, fries, soups, cereals, 'cider', cocktails, deserts, sodas, sauces, egg cheese and milk substitutes. So that's my plan. What do you guy think, and what ingredients would you add and why? And what would you call it? There are loads of things I left out as everything will change as I work through the process. Thanks for reading, Haydn

ISOLATION TRANSFORMER 120 to 120v

Often a GFCI is too sensitive outdoors. But I've heard that an isolation transformer might save you from electrocution. How safe would an isolation transformer be for running a fan, angle grinder, blower, space heater, etc outdoors? Where can I get one that will handle the amps I need?

Using quickrete to sound proof walls?

After reading online I thought about an easy cheap alternative to lessen the noise in my garage studio room from escaping to the outside world.  After the new construction the smaller space seems to echo much more than before, thus the need for more soundproofing/deadening.  I though about building forms with plywood backing and filling them with readymix quickrete with wire mesh on top.  After fastening the frames onto the brakets I have that will be firmly fastened to the wall in staggered pattern drywall and carpet padding will be applied on top of the plywood side of the form that would be facing toward the middle of the room thus creating a second relatively thick layer of sound deadening with roughly 1 1/2 inched of dead air space trapped between the outer and inner layer walls.  Has anyone ever tried this?   Thoughts, comments, suggestions welcome.  To clarify:  From outside to inside I would have:  Siding - Standard Wrap and OSB - Stud- Moisture Barrier- Insulation - 5/8 Drywall - 1 1/2 inches of dead air space - Wire mesh side of concrete forms 1 in thick - concrete- plywood backing side of form - carpet padding - drywall - carpet   Thanks.  John

Relativity and why E can't really equal m²

See this topic as something that should be in our now deeply missed random fun section.Everyone learned in school that there was Albert Einstein and we have to thank him for bringing humanity into the next evolution.At least in terms of understanding the universe, quantum physics and things like this.Over the years I developed my own funny theories on why Einstein was so stunned that his calculated energy output from the first nuclear test was off by a factor of about 4 - meaning his calulations were at least 4 times lower than the real thing....The official story about this "mistake" is something like this in a destilled and drastically simplified way:"We did our best but this totally new terrain, theory got corrected by real world test.We now know how to factor all this in correctly for selfsustaining nuclear reactions with a critical mass."The real explanation with all calculations and so on was document of about 200 pages....The inoffical story about the first test and the corrected results was a bit longer and personal.Nicola and ALbert had a long hate-love relationship.Similar interests and theories got them together, diference in the opinion what can be put into our current math system for calculations and conflic of used terms got them apart.But like every good couple they always got over their differences and corresponded again - sometimes with a year or two before they were ready to talk to each other again.In this story Nicola had massive arguments with Albert about the required, sustained and released energy levels for Gadget - the first test of the Trinity series.To give you an idea why it was so hard for both to understand the other or to accept the other's calculations:Einstein based all his theories and what we use today when it comes to math.Tesla however prefered his own mathematical system, one he promoted and got into every day use in many US schools at the time.In simple world it was based on a big circle, I like to call it the circle of math.Almost all of our natural constants (that were known back then) were present as lines, multiplication, squre roots and more were as easy as following the right lines and pathways indicated on this circle.Both system, ours and Tesla's provided the exact same results, the later however without any need for additional "notes" along the way or complicated formulas.And even worse when it came to energy.Back then science alrealy knew there is more than what our laws of physics state and what we know.And what we could not really understand and only proove in theory is now as common as butter on your bread.Thinks like quantum mechanics, quarks or the fact that you can't observe a light particle on a quantum level directly, only as its sum....Tesla however already had "a higher understanding" on how different energies interact and how get from one form of energy to another.Like his tesla transformer, the radio transmitter and so on.While we had no clue at all Tesla already studied the ionosphere, he had different name for it though.For him it was obvious that it is not just a reflective barrier for radio waves but that it also has a very energy potential on its own.Either way the argument was the Albert only factored in the mass of the nuclear material, the explosive forces from the ignition and the corresponding implosion.Basically everything we could see, explain or theorise about back in the day - and it needed to be possible to claculate it somehow to match expections.Nicola made the claim that during the explosion also a lot of electromagnetic energy is created together with what he called a break in the fabric of the universe.Not only that but the electromagnetic shock (we call it now EMP) is not really a single thing but spread basically over the entire know frequency range, including visible light.The visible light claim was confirmed during the test by shadows burnt into walls....You can clearly imagine how good old Einstein must have felt seeing his good friend being dead serious about things he could not have the slightest idea about.After all there never was any test before and certainly none with Tesla present...How the personal story between the two continued can be found online if you some digging or if you prefer in a well stocked library - yes they still exist as real place ;)What was mostly left undocumented, at least for public eyes was the implications from the Trinity test series.That Tesla really was onto something even if the smartest man on the planet could not understand a single word of it became painfully obvious.At least for Albert....In his later theories you can find the influence the revelation of finally understanding why his calulations were of and most importantly understanding what Tesla meant by the fabric of the universe.E does not really equal mc² for quite a few reasons.Firstly because it is based on the assumption that nothing can be faster than the speed of light.So did our best to measure it, cheated by making definition of light speed and meter based on the same thing.I mean: If you take two "unknown" variables to create a result and then use the result to finetune the input- how accurate can it really be?....Today we long know that there things travelling much faster than the speed of light, for example gravimetric shockwaves when a distant star goes booom.We detect these "gravity quake" now so we can aim our big telescopes to where it happened and see it in "realtime" once the light arrived long after the shockwave.And if you dare to re-do the original calculations for Gadget and factor in that a gravimetric shockwave travels about 4 times fast than light you get an idea why Tesla already knew all about it.What came out of all the offcial calculations and theories is well known.What is missing from E=mc² was never officially published by Einstein...Applications for the possible damage to what Tesla called the fabric of the universe.We are trained to only use our brains in two dimensions.A bit of it comes from our evolution as since the dawn of time we prefered creating a flat image over creating a sculpture with similar details.Some people though can use their brin in three dimensions with ease, like when a really good sculpture artist say "The sculture is already in the rock, I only need to remove what is covering it."And sure enough every color or texture detail of the rock ends up in exactly the right spot to make the result perfect.Musicians are quite similar, a lot of them have no clue about notes or how read them to create a nice tune on an instrument.Some only need to hear a song once and can repeat it on all instruments they play like they studied the song for years.Others hear the vocals only and create tunes and melodies from it that not only match voice act but also reflect on the mood, the feelings.In some really good songs you only need to hear the instruments and can almost imagine what the singer would sing to it...A very few can do similar with math, we like to call them a genius because we can not imagine a complex and long number as a series of meaningful images or emotions paired with colors - for example, as there many more ways to deal with numbers...People like Einstein realised after the Trinity tests that the EMP and corresponding electromagnetic effects are too strong to be measured by anything unless it is from a great distance.That means, like lumen per area, the strenght of the electromagnetic effects increase exponentially the closer you get to the source.Still... No big deal right?Well if you dare you make a frog levitate in a magnetic field, won't be a healthy experience for the frog but it will levitate.You can look these frog experiment and corresponding scientific explanations up online if you are bored enough one day.The point is: If a frog can be excluded from gravity in a magnetic field of suffient strenght, orientation and other features, then what else can "float"? ....Or more to the point: Why exactly does the frog float if he is not magnetic enough to begin with?....We have no problems visualising or imagining the shockwave from a big explosion like Gadget.High speed films show us that there would be an expanding perfect sphere, only object like the ground limit this experience, but you see it nice in underwater explosions!What most people can't even begin to understand is how a shockwave of which the EMP is only a small part acts, travels or what effects it migh thave.Unlike a normal shockwave we have something like redox reaction happening.The explosion creates an unimaginably strong electric impulse, a bit like all lightning strikes in world feeding into a single lightbulb at the same point in time.For argument sake lets say is almost indefinately high.However, like in an ignition coil this impulse creates and equally strong electromagnetic impulse.And since the entire reaction at this point is far from over we get a harmonic resonance and feedback system.Imagine a second you stretch around the globe as a band and then you cut a mm off it - that would be about the timeframe for the most intense electromagnetic field swinging around at all sorts of frequencies.And during this very short period of time a bubble is created that expands what modern sciensts now call the space - time - continium.Same name as in the movies but this time based on quantum theories and such things to explain gravity.An awful lot of energy is trapped inside this bubble and once the initial reaction is over the electromagnetic impuls disappears and only the normal reaction from the explosion continues.The bubble however does not pop or disappear, it implodes.All this energy is compressed basically to a single atom size and released.Sadly this energy has no visible effect, nothing we can observer with our eyes or instruments...Again we use quantum theories to explain what must happen to find way to it "visible" somehow or to find way to really measure it.Gravity sensors are a result of these theories and developments and now part of basically any good GPS satellite or space probe.Some fancy phones have them too.What would actually happen if we would have found a way to affect the space time continuum in a very controlled way?Without explosions or such bad things, just by using simple technologies.Now I would have to explain things in at least four dimensions, which means most readers would shut off now.Using five would be insane, I know :(So let try to ignore how things work fr real and do what every good scientist does: simplify to make the imagination work in just 2 or 2.5 dimensions.Put a cork on a pond a throw a rock in it.It moves, mostly wobbling on the waves but it moves away from where the rock was dropped.If it could be "anchored" at the right spot between two crests of the wave it would move with it, like a surfer on a good wave does.A craft that creates our field from the inside and in a neutral configuration would create a perfect sphere.What would that mean for the craft and those outside observers?At a first glance nothing until you realise the craft has no mass at all.You could lift a 5 ton vehicle with your little finger and flick away like something you found in your nose.Unlike our suspended frog the craft would create a field bubble where gravity diverts around it.Gravitity is the driving force of the space time continuum.Without it there would be no time, without time there would be nothing.If you would be inside the craft and be flicked away by a finger you would only realise it if you looked out of window or onto a screen showing the outside.As the craft does not exist in the normal space time continuum, so to say, the same non existing effects of things like acceleration, g-forces and such can't apply for what is inside either.Well, at least until you reach the wall, the suddenly all is stopped and has to enter our normal continuum again.You would be mince meat on some wall inside what is left from your craft...Increase the field strenght to overcome inertia of smaller particles and even air molecules or dust particles are diverted around the field.Nothing though that would rival the mass of the craft in a significant way, like flying into a solid wall or mountain....A modfied field geometry allows to affect the shape of the bubble.To keep it in two dimensions, imagine a ping pong ball as the field that you press into some slime, or similar fun stuff.Start moving it and it forms something like a wave in the front and something like a wake on the other side.Our field can shape the bubble so that our space time continuum would look quite similar - if we could see it instead of theorising about it.As result the craft now moves in our normal continuum without having and appearent form of engine.The bigger you make these "waves" with your field, the fast you go....And suddenly those impossible movements in the sky that are always dismissed as a hoax or weather balloon make a lot more sense.Be it a Scalar drive, the Fluxliner, VR7 and derivates, they all use garvity as a propulsion system.Fair enough you might say, but what does mean in terms of where we might have been already since almost one hundred years....A gravity based drive system in the sience fiction section has many names.Warp Drives of course comes to mind first.But also FTL drive or Jump Drive.Just because gravity waves are much faster than light already means lightspeed is not really a limit and hasn't been for a very long time.Why do you think superconductors were first developed by/for the military? ;)With no mass it is only a matter of the avilable energy how fast you can accelerate and what top speed you can reach....Or to be precise: How effiently you can create an insanely strong electromagnetic field.Make you wonder what else came from understanding what things like a Hedron Collider can do...With an estimated energy output equal to truck sized generator you could make it from Virginia to Mare Tranquillitatis in about 10 minutes.Make it 30 if you want to get out and stretch your legs when you are there.Some now say "I don't care who or why someone goes to the moon."But what about those who think climate change is real and how we produce and use energy plays a big role in it?Let alone those actually considering that fossil fuels might run out one day....If you have a gravity drive then you have a very neat way to create almost limitless, clean energy.....I leave it up to what it would mean if everyone and everything in our world would have access to free and virtually unlimited energy....Isn't it good that all this is just a nice story and that all is just fiction with no relation to reality?But if E does not equal mc² then how relative is our reality really?

Parys Mountain

General interest: I went there (surface) this year, it's pretty-much dead (due to heavy-metal contamination), a spooky "outer-space" sort of place. Near Amlwch on Anglesey (that's Wales) The site contains several mines worked since the Bronze age, it was once the largest copper mine in the world. This site has some great photos of the underground levels, recently drained: www.parysmountain.co.uk/ (I nicked an image) note that 1 fathom is 6 feet. Google Earth: W 4o20 '40", N 53o23'10"

universe expanding forever?

I saw this article on the BBC news site: http://www.bbc.co.uk/news/science-environment-11030889 which has some astronomers apparently claiming that they have now worked out the fate of the universe from measurements on distant stars magnified through a galactic cluster. The final quote is: Professor Priyamvada Natarajan of Yale University, a leading cosmologist and co-author of this study, said that the findings finally proved "exactly what the fate of the Universe will be". This seems like a pretty bold claim to me - I was thinking that even if we had a lot of such measurements then we would still only be working out the geometry of space/time in the region of our universe that we are capable of seeing. This is likely to be only a small part of the whole universe due to the galactic horizon imposed by the age of the universe against the speed of light. Also, even assuming that the whole universe of 3D space and time that we live in behaved the way they are saying, this is still only working out what would happen due to the universe's own internal dynamics - there are ideas coming out now about our universe being part of a wider multiverse outside the realm that we experience as normal space and time, so even if the universe did expand into a "cold dead wasteland", then something could possibly infringe upon it from outside space/time and make something different happen at any time in the future. Some of what's going on here is just bad journalism - there's a longer article here: http://pda.physorg.com/darkenergy-universe-magnifyinglens_news201427857.html which gives a fuller version of the same quote: "The geometry, the content and the fate of the Universe are all intricately linked," says Natarajan. "If you know two, you can deduce the third. We already have a pretty good knowledge of the Universe's mass-energy content, so if we can get a handle on its geometry then we will be able to work out exactly what the fate of the Universe will be." This is a bit more cautious but there's still this idea that by making measurements like this from just one point in space and time we can work out the fate of the whole universe, which I don't really believe. So I reckon these sort of predictions should be taken with a massive pinch of salt, rather than definite statements of what we know. Which may be obvious, but I wanted to say it and see what anyone else thinks?

What free ebooks should I check out?

I'm going to be hiking in Japan for a week soon. The last time I did this was about eight years ago and I hauled a few large paperbacks along with me which I devoured in the first few days. It was far too much dead weight and took up too much space in my backpack. This time around, I'm going to be borrowing a Sony ebook reader from a friend. Since many ebooks cost more than real books and there are a ton of classics I haven't read yet, I'm going to load it up with reading from Project Gutenberg and feedbooks.com. So far I have selections from Mark Twain, Jules Verne, Nietzsche, Cory Doctorow, H.G. Wells, and Sir Arthur Conan Doyle. Those are already be more than enough, but I want to have options! What other free classics should I check out? I normally geek out on too much non-fiction, so I want some stuff with wonderful language, characters, and stories. Let me know if you have any ideas.

Flashing LED problem?

Hi everyone. I mess around with HO scale slot cars and have had decent success lighting them with LEDs using track voltage and simple resistors to power them. I have ventured into the use of full wave rectifiers to smooth out the power and a small capacitor to eliminate the flicker. The problem I am having is when trying to use multiple blinking LEDs. Single blinking LEDs haven't caused any problems and I've had good results with them. The problem starts when I use more than one. I can get a pair of them to work on the bench with out any problem at all, but when they are soldered to the slot car chassis they might work for 3-5 minutes and then they stop blinking, and usually get hung up on one LED staying lit. What is even stranger is if I take a piece of brass rod and touch the anode of the dead LED, it will light up momentarily (and the other will go out). I only have so much room to work with so flashing circuits, large capacitors and voltage regulators are out of the question. Keep in mind, these cars are the size of a hot wheels or matchbox car, and the chassis uses up most of the internal space. Any help would be greatly appreciated!!!

Build Night Resources

BUILD NIGHT OVERVIEW Instructables sponsors monthly build nights at makerspaces (and hackerspaces, fab labs, student groups, libraries, etc...) around the world. Each month we partner with a different company to send materials and/or tools to run a workshop at your space. In return your space posts Instructables from your build night. If you are interested in being directly notified about future build nights fill out this form. You will receive e-mails when new events are announced in the forums. IMPROVE INSTRUCTABLES + FIRST TIME AUTHORS: Naturally with such a large participation in the build nights (2000 people globally for sugru) there will be some first time authors. Here is some important information to share with your community before (or during) your build night. How to Use the New Editor: this is a handy guide to help you get the hang of the new editor. How to Choose a Title and Keywords for your Instructable: learn how to pick a great title that will give your project as many views as possible. You don't need to include the sponsors name in the title of your project, but I'd recommend including it somewhere in the first step. Feature Checklist: this is the checklist we use to decide if an Instructable should be featured on our homepage. It is a great resource for writing high quality Instructables. How to Take Great Photos with your iPhone: these are some great tips for photography with an iPhone. Basic Photo Editing: improve your images with a few simple tips. It is especially important to have a great main image to improve the quality of your projects. English as a Second Language: If english is your second language check out this series of forums. We encourage people to post Instructables in their native language. If you would like to post in both English and your native language you can use a translator. Author Rimar2000 is a great example of this. MOTIVATING MEMBERS TO POST INSTRUCTABLES: The most common question/issue that came up was how to motivate build night participants to post Instructables and take photos during the build night. I came up with a few tips and solutions. I’d love to hear your thoughts on this and if you have any other ideas on how to encourage your members to post projects during their build. Planning ahead of time. Take suggestions from your community on what projects you can make at the build night. This will focus the workshop and motivate people to actually execute on projects. Post projects ahead of time: For spaces that are expecting more beginner/intermediate participants (especially young students) organizers will post Instructables before the event for participants to follow during the event. Demonstrations at the beginning. Have a short 20-30 minute demo at the beginning of the event and use the rest of the time to make projects. Breaking into groups. Split the attendees into groups pairing beginners with experts. Each group can work on a different project. This is especially important for more advanced build nights that have electronics. Designate a documenter. Have a designated ‘documenter’ for each group. They will be in charge of taking pictures during the project build. If someone has an iPhone or Android they can download the Instructables app for free and upload their photos from their phone directly to the website. PUBLICITY: One of my goals with the build nights is to get publicity for makerspaces and individual makers. Here are some ways we’re working to promote y’all! Homepage Promotion: get pictures of your makerspace on the homepage of Insructables. Take excellent pictures from your build night and we just might feature it on our homepage. Your space must also have a group page that we can link back to (see below). Tweet at us: tweet to your followers that you are hosting a build night and we will re-tweet you! We will also encourage our sponsor to re-tweet you as well!! GROUPS: I’m working to get a group page for every makerspace on Instructables. Check out all of the makerspaces with groups (here). The requirements to get a group for your space: You must have 5-10 Instructables published by members of your makerspace before we build you a group. It doesn’t matter if they were published 5 years ago or yesterday. You must agree to post projects on a regular basis. This is just to confirm that the group doesn’t go dead. 1-2 projects every 1-2 months will do! If you are participating in the build nights this should be easy. Contact me at carley@instructables.com if you think your makerspace is ready for a group. EARN A FREE PRO-MEMBERSHIP: everyone that publishes an Instructable will receive a 3-month pro-membership. SUPPORTING MAKERSPACES: Build nights were the result of a conversation I had with Josh from All Hands Active. He was looking for ways to get new people to his space and create new events. What other ways can we help achieve your spaces goals? Here are some suggestions from the hangout. Please let us know if you have more ideas! Live Stream Build Nights - spaces that are hosting google hangouts on the same day could connect via google hangout. Live Instructions: host a series of “how to” google hangouts where we teach you basic skills like soldering, basic electronics, etc...

How can I modify this circuit to sequentially turn on LEDs in parallel, while avoiding voltage drops? Answered

I have a single pole, 12 throw rotary switch which I want to solder to a set of LEDs so that rotating the switch clockwise lights more LEDs as follows: 1 = 1 Red LED 2 = 2 Red LEDs 3 = 3 Red LEDs 4 = 4 Red LEDs 5 = 5 Yellow LEDs 6 = 6 Yellow LEDs 7 = 7 Yellow LEDs 8 = 8 Yellow LEDs 9 = 9 Blue LEDs 10 = 10 Blue LEDs 11 = 11 Blue LEDs 12 = 12 Blue LEDs Since there will be a voltage drop across the diodes, the LEDs at the start of the chain will get progressively dimmer, and increasing the voltage would blow the LEDs in shorter chains. One modification I know I could already make would be to not use the first 4 diodes on the yellow LEDs, and the first 8 diodes on the red LEDs, as a minimum of 5 yellows and 9 blue will be active for each position. This still leaves a maximum of 3 diodes in each chain, which I still think would cause the lights to be much dimmer. Another solution I can think of is to have multiple wires coming from each terminal of the switch, each with their own diode, which would ensure all active LEDs had the same brightness (I'm not sure if this would cause the whole chain to be dimmer than shorter chains or not). The downside is this would need  31 wires rather than 13, and that's only if I bridged together all the shortest LED chains of each sequence: individual wires for absolutely every position would mean 79 wires+diodes). To put this in context, I want to create the health bar from Dead Space 3: If you can suggest a way of improving the circuit, or totally re-designing it, it'd help me loads! Thanks!

Electron Club Open Day Show and Tell, Glasgow 13 June

Electron Club Open Day2pm-8pm Saturday 13th June 2009Centre for Contemporary Arts (CCA), 350 Sauchiehall Street, Glasgow, G2 3JDThe Electron Club is a voluntary run space where people interested in things like free open source software, circuit bending, hardware hacking, computer recycling, streaming, audio and video editing, green technologies, and amateur radio can meet, use equipment, and share anddisseminate their skills and ideas. The space supports both individuals developing their own projects and a number of group projects, all of which are not-for-profit initiatives with a community, educational or environmental aspect to them.Now in our third year, the Electron Club Open Days are an opportunity to see and try out a range of things that people do, as well as having the opportunity to meet others with similar interests, make, chat, discuss and enjoy.TESLA SOUL - Electron Club Makers Fair and homebaking - Bajery in the Makery!Stalls and demos by electronic makers, designers and artists. An opportunity to see and play with some of the projects created by Electron Club members and related groups - a theremin menagerie and mini synthesizer kits, 3D paper engineering, circuit bending, micro FM radio,DIY wind power technology, creative computer trash recycling, 101 things to do with a dead keyboard and much more. Plus some of the excellent home-baking that has been hallmark of all our Open Days. Come and do a bit of soldering or have a cup of tea and chat with the people who make things.TAPE-WIRE-HEAD-SCREEN - music, film and sound artsThe Electron Club includes many people working in music, film and experimental arts. For the Open Day we will be showing a preview of films from Document, the UK's leading human rights film festival, with works ranging from front-line reportage to cinematic explorations of what it is to be human, along with films made at the Electron Club by the Digital Desperados, a film-group for young black and Asian women. We'll have a live performance of Alvin Lucier's legendary "Music on A Long Thin Wire" by members of 'Obscure Desire of the Bourgeoisie' and BuffalobuffalobuffaloBuffalobuffalo'. Outdoors, artist Lucie Potter will invite people on a specially planned sound walk around the Garnethill area.THE LIFE OF SOCIAL THINGS - socially-engaged technology forumA series of discussions about different ways in which society and technology come together.Glasgow FabLabsFabLabs are small scale fabrication and construction workshops that provide computerised production technologies on an artisanal scale making them available to communities and independent makers and designers. From inner-city Boston to remote Indian villages, FabLabshave become a worldwide network of community technology centres. Glasgow FabLabs is a project aiming to bring such a centre to Glasgow. This forum will present the ideas behind the Glasgow FabLabs project and explore the benefits of community-access technology.Community Media and Citizens JournalismThe internet has offered a platform for communities and groups outside of the mainstream media to have a voice and share knowledge. Whilst there are many notable examples of such activity, the tools to create such a democratized media space are still often out of people's reach.This forum will look at some practical examples of community media coming from Glasgow, present some current projects looking to make ordinary people's voices more prominent and explore the relationships between the grass-roots and mainstream media.Technology, Social Justice and the EnvironmentHow can we use technology for the greater common good? Whilst the advance of technology promotes the promise of a better world, that promise has often been compromised or undermined in how we make use of such advances. Certain technological developments have contributed to environmental and social problems on a scale arguably never seen before.Technology, however, has also been used to tackle such issues as climate change and social injustice. This forum will share and explore some practical examples being used in Scotland today, from noise monitoring devices to participatory video and community mapping projects.RAFFLE - broadband fundraiserThis year we are raising funds to improve our network facilities at the Electron Club and we will be doing a raffle with prizes including a group voucher to go paintballing.http://www.electronclub.org Contact: openday@electronclub.org

McMADSAT make and do, show and tell. Scotland's first Maker Event 2009. Full report

Report of the McMADSAT event 14th March 2009, at the Glasgow Science CentreWe had a fantastic day. Outside it was a grey gale of a day, but inside was a riot of colour and activity. The aim was to enthuse the public with the fun of making things from a variety of technologies. Anyone who wanted to, could join in, make something and take it away with them, and all for free. Hundreds of people of all ages came along and had a great time. A general video of the event can be seen at https://www.instructables.com/community/Mc_MADSAT/ (Thanks to Les Oates for making this excellent film for us).I am happy to discuss further with anyone planning their own event, and you can see more about it and the process by which I got the event going, at http://mcmadsat.blogspot.com/ExhibitorsStar Guest, all the way from London, was Professor Maelstromme (AKA Amanda Scrivener), who brought her beautiful creationsWhat can you make from a dead umbrella? Display of the possibilities for reusing the fabric and structure of dead umbrellas.The Tea Party. 1950s style tea party made from a combination of hand made fabric and edible pieces.Cardboard structures from the students of the department of Architecture at the University of Strathclyde.Greensteam's steampunkery, 101 uses for a dead keyboard and other examples of her work as shown on Instructables.The Offline Mechanical Blog – a very old manual typewriter with continuous paper available for the public to type their messages and thoughts on for all to shareLemonie (another Instructables enthusiast, who travelled up from York especially) brought his amazing conversion of a VHS player-into-toaster that makes toast with VHS imprinted in it. He also brought his nice LEGO USB stick, a lantern made out of a tin-can & glass. and his *untested* wind-turbine, made from VHS player parts.On the Young Makers stand we had a display of virtuoso Lego constructions and an extensive collection of home made Steampunkery.The self-replicating machine from the department of Design Manufacture and Engineering Management at the University of Strathclyde, the Reprap, was on display and moving but sadly not reproducing on the day.ActivitiesThe public were offered a wide range of free hands-on activities, which ran continuously all day, to 'Make and Take'Soldering - make a solar theremin (or a robot). 16 of these were made and all worked first time. Some were taken for a trial run in the sun and a video of this can be seen at http://www.youtube.com/watch?v=ZzUZMon3vpA The Stemnet ambassadors helped visitors to make their own Musical Straw Oboes.One of the most popular activities – especially with children – the Stemnet ambassadors supervised the making of many handsfull of Gloop.The Stemnet ambassadors used the plastic Polymorph for visitors to make a fingerprint keyring to take away.Fishy things - Busy Bees Art studio provided painting and collage fishes to make, particularly for our very young visitors.The Glasgow Crocheted Coral Reef invited visitors to try their hands at crocheting and contribute to the growing coral reef, all made from wool and even strips of plastic bag. Many total novices not only tried their hands but actually completed a piece of coral to contribute to the reef. This workshop area was very busy throughout, with visitors typically spending 30 minutes or more participating. Many thanks to my civil engineer pal who ran this.House of Cards - visitors could make and take their own set of the design classic 'Eames cards', which slot together to form fantastical structures. Ideal for recycling old greetings cards.Cable necklets, keyboard bracelets and keyboard film wallets. All made from recycled/repurposed materials from dead keyboards. Popular with adults and children alike.Risk assessments were provided to the Glasgow science centre, for all the activities. There were no injuries and the 'emergency first aid bucket of water' was not needed as there were no soldering or gluegun burns.Participant Presenters30 people were involved on the day, either as exhibitors or as workshop facilitators. An essential component of the team was the group of11 Stemnet ambassadors, most of whom were there all day. It would have been impossible to run so many activities without them. Another group in the team was the members of the Glasgow Electron Club who, with some friends and a Stemnet ambassador, ran the soldering workshops continuously all day. We were particularly fortunate to have two exhibitors travel up specially to take part. Several exhibitors were entrepreneurs who gave their time for nothing, even though the venue rules meant they could not sell anything, nor charge for the activities being provided. This was especially generous given the harsh financial climate just now. Everyone said they had lots of fun.PublicOver 1,000 people visited the Glasgow Science Centre on the day. The BSA/NSEW assessment forms collected only represent <10% of the visitors to the McMADSAT area. Stallholders and workshop facilitators estimated a total of about 425 active participants (people who did an activity, or asked questions and generally interacted with the displays) by 1530 (GSC shuts at 1700). However, even these only represent a proportion of the people visiting the event which, although not recorded, probably amount to about double that, since most of the activities were taken up by children accompanied by other family members. The numbers at any given time were variable, depending upon the GSC's own activities/talks etc. I would estimate that the McMADSAT area was visited by at least 700-800 during the day. From the few assessment forms returned, and from chatting to the public, it was clear that most had come simply because they were coming to the GSC anyway, but some (mainly young adults) had come as a result of internet and email information or because of the Metro article. The GSC visitors seem to be mainly families with children of primary school age. The University of Glasgow Steampunk Society had come especially to make contact with the steampunk element, as featured in the Metro article. We also collected some contact details for future events. BudgetThe total budget for the event was the £500 grant provided from NSEW Scotland scheme. This had to cover all the exhibitors' costs and the costs for the free make and take activities, plus all publicity etc.In-Kind Sponsors:The Glasgow Science Centre provided free space, tables, cloths, technical assistance, without which the event would not have been possible at all.The publishers of Make and Craft magazines, O'Reilly's, did not feel able to sponsor us in the same extent as they did for the much larger event in Newcastle on the same day, but did send boxes of back issues of their magazines to give away, which probably amounted to an equivalent of about £300 at UK newsstand prices.Clockworkrobot.com provided more theremin kits than contracted for, which were themselves at cost price.Madlabs provided free batteries for all the kits they supplied at cost.Instructables.com assisted with publicity and allowed the use of their logo.VenueNone of this would have been possible at all, particularly on this minimal budget, without the kindness of the Glasgow Science Centre. The Director agreed immediately to offer us the space free, plus the use of tables and technical help to enable this event to take place. We were able to partially set up the night before which was very helpful in avoiding a scramble on the day. We were able to get the loan of 4 GSC soldering irons which avoided us having to get personal ones PAT tested. This was the ideal venue for us as it meant we really didn’t have to do a great deal of publicity as we could be sure of an audience from the GSC's normal throughput.PublicityThe event was listed in the NSEW diary and in the university of Strathclyde's NSEW information. Posters were distributed around venues in Glasgow and information posted on relevant websites. A blogspace http://mcmadsat.blogspot.com was set up as a temporary web presence to refer people to. The Metro published a small piece which was a wonderful boost.Lessons for the futureNeeded more helpers and more exhibitors. Outdoor displays would have been impossible as the weather was dreadful, but it is still necessary to have some more dramatic displays as well as the hands on activities. Successful soldering for novices really needs 1:1 or 1:2 supervision. The budget only worked because minimal publicity was done at low cost and all the participant presenters were generous with their time and resources. Anything more ambitious than what was done on this occasion would need a larger organising team and significant sponsorship.

China's first Maker Faire !

April 6th was a long night that would be followed by an even longer day. Hours stretched like taffy as the Airplane pulled me across time zones. I was on my way to the Shenzhen Maker Faire which was being put on by Eric Pan, the founder of one of the largest open sourced businesses I know. Eric is a visionary, and his vision to inspire more makers in China connecting them with a global maker movement through the concepts of openness, sharing, and innovation inspires me and hundreds others to come to Shenzhen to share in the first Maker Faire in China! Hours ago I was at Instructables cooking my Last Breakfast for the office and gaving my Last Hugs. Qarly, my new friend, had helped my stay up all night organizing my tickets and suitcase. She went with me to the Payless shoe store on her bike as I walked barefoot. Yes, I started my journey shoeless. I had traded in my Vibrams at REI for a large backpack so I could cram as many arduinos and 3D printers into it as possible before leaving to go spread the good words. Here are the good words as I see them right now: "It Can Be Done." Yes, with a solid mission, a relentless attitude and accepting being shoeless (or jobless, or hungry, or ...) it's possible to accomplish the things you dream. Boom, back in that tin can flying over the Pacific. My schedule starts with a trip to Hong Kong to meet up with instructable's member Prank. Alex Hornstein and I had recently completed an adventure in 3D printing called the Pocket Factory in which we traveled across America seeking the business models behind low cost 3D manufacturing. He is now back in east Asia being the revolutionary philosopher engineer he is. I land at 8pm and head out into the city of the future. Hong Kong is a city of millions, beautifully lit tall buildings, zippy public transportation, and the largest pay inequality in the world. Looking out the window I keep wondering if this is the rich part, or the poor. Then I was there. I made it to IFC - a gigantic mall in the heart of Hong Kong. The metro stop inside it is called "Hong Kong Station". Yep, shopping is big here. We hung out on the roof of IFC talking projects. Without giving too much away too soon let's just say Alex is on his way to revolutionize the micro solar industry. We took the familiar ferry route home and I spent the night organizing and updating the social world since I knew in a few hours I'd be in China... and in China, no one can hear you tweet. Before I knew it I had to be off! It was 6:20am (HK time) and the ferry leaves at 6:40, I had a long day ahead of me and I haven't slept yet. Holy crap! I ran and got right back on that ferry from Lama to the mainland. Passing all the tall buildings once again and rushed onto the MTR. As we sped along the Hong Kong landscape of tall towers slowly turned into green rolling hills and the people on the train spoke less and less english. I crossed the border into Shenzhen and it was there I met Ani, the Monk. What a beautiful lady! We had a great conversation involving LOTS of smiling, drawing and almost no words. She was from Hong Kong and we were now friends. We traded bracelets and now I have one more reason to learn Mandarin! I finally made it all the way to Xi Xiang, the metro stop which was walking distance to the Maker Faire! I was getting pretty excited, I had lugged all this stuff across the world, and finally I was going to meet the makers of China! After a long and potholed walk I finally made it to the gate where a nice young Chinese lady helped me carry my stuff, we walked down a long outdoor hallways at F518 the "First Experiential Sharing Space in China" which was filled with sculptures and art. Billboards around me advertised hip hop dance classes and robots peeped from the windows. I knew I was in the right place. Right near the entrence of the Maker Faire was a strange robot. It was the size of a small house and it served books. They have robot libraries in Shenzhen. Wow! The more I learn about this place the cooler it seems! The faire is a large three story space with a media space on the first floor where people can buy "chinese make" a magazine called Radio that has been teaching people how to make stuff since 1955. The publishers of this magazine are also the ones who do the translation for Makezine! The second floor is filled with long tables of makers, a huge hall filled with running robots, dancing droids, DIY laser 3D scanners, touchless IR interfaces, octocopter (no, not tacocopter) and all the awesome stuff you'd expect to see in San Francisco, except this is Shenzhen. There are makers everywhere! Upstairs there are people making clay figurines, another instructables user - Star - runs a workshop around Canidu (yes, you can do!), her company which makes an electronics learning tool. This movement is obviously global and the Shenzhen Maker Faire has pulled makers not only from all over China, but all over the world. Eric Pan, the founder of Seeed Studio employs 70 people through an open source project and through this faire has inspired hundreds. At the after party, you can really tell how proud Eric was to have brought amazing makers like Mitch Altman and David Li from the Shanghai hackerspace together. Eric has a new project in the works right now. He's soon to be a father! I can only imagine how proud he will be when baby Eric Pan picks up his first blinky LED kit. Now that's some serious making! +Bilal Ghalib PS. Eric in the last picture is not dead, only extremely exhausted!

Can I Turn My Old Macbook Into a DIY Mac Pro Tower?

Preface/Background: I am fairly new to DIY tech projects. I have built two HTPCs, but I doubt that really counts. It does, however, give me a basic idea of how all of the components go together. I'm not terribly savvy when it comes to specs of computer components. I have an '08 Macbook that has just been gathering dust since I upgraded ~1 year ago. Recently, my side job as a freelancer (graphic design & video) has been picking up. My new machine is pretty powerful, but the time it takes to get my laptop setup with all of my peripherals is starting to get old. There are also times when I crave some extra speed & I often have to stop working in the middle of a project to clear up disk space or set up an external drive. I remembered seeing a project where Mosburn converted his macbook into a Mac Mini on Gizmodo a few years ago, which got me excited. It was written in 2008, and may be a little dated. I'm looking to do a similar project, but I'm not really looking for size/design. I'm looking for POWER! The Macbook in question is version 4,1. As I said, looks aren't a big issue for me (nor size). I now have an extra room in my house and it is going to be set up as an office. Everything still works on the laptop, although the battery no longer holds a charge. I initially planned to sell it, but with the dead battery and some cosmetic damage, I could only get about $200 for it. I think this project would be more valuable to me than that. Project Goals: -Use as much of my existing laptop as possible (the whole buffalo) -Use a case that allows upgrades (more memory, more drives) -Increase memory (current: 4 | desired:16+) -Increase disk space (current: 80gb | desired: 2tb+) -At least 1 Solid State I know the Mac OS is pretty picky when it comes to components, so the initial question is: Will the system accept my desired spec upgrades? I know that I have to use compatible brands, I just want to make sure there isn't some sort of "maximum" hard coded. Will I be able to use both Solid State and Disk drives? I would like to get a smaller Solid State as a primary, and a couple of large disk drives for storage and scratching. I may get a dock so I can quickly switch drives that are strictly storage, but for now I just want a couple TBs inside. Also, would you suggest using the existing power cable? Or would it be benificial to swap in a new power supply? I'm not sure how intensive that might be, but I'm guessing a few more drives will require it. I think it is safe to assume that I will need to use some advanced DIY techniques, as far as my experience goes. As I stated before, I've built a few PCs before, but these were all fairly simple. Connecting components to the motherboard were as easy as plugging them in. I've done a (very) small amount of soldering before on other DIYs, but they were all done on fairly big parts and precision was not an issue. If soldering might be needed, I will need some help with this as well. I am hoping there are some guides out there to help me understand what goes where on my particular motherboard. I'm also a little worried that I may have to do some cutting (as done in the project linked above). Hopefully the fact that I don't need a small case, I won't have to deal with that. I plan on buying a high res screen to use with this machine, but I'm not sure what I plan to do with the existing LCD yet. I'm not sure how much I might be able to sell it for, or how much it might cost to buy a stand to mount it with. It is a pretty nice screen, but it's long before the time of the Retina display, so it may not be worth messing with. If anyone has any suggestions for what approach to take, or a link to an existing guide, please share them below. Another fear I have is that the variations in MacBook models may make finding an applicable and useful guide more difficult. Another note: Cost isn't really an issue. I hope to first accomplish this project using mostly the materials at hand - worrying about upgrading my specs later. If this is possible, the only expenses should be a new case, a few cables, and possibly a new power supply. I'd like to preemptively thank anyone who might offer help. I've been wanting to make a move to tech DIY for years and this project seems to be a great starting point. I hope this leads to many more and that I can soon be a helpful contributor here as well.

Idea for a non-ideal Carnot cycle based engine.

Initial Stirling engine conceptFor some time I was contemplating an idea for a Stirling engine that would work quite differently than the other designs that I came across. Whole internal volume of an engine may be viewed as a closed-loop pipe, trombone-like slide mechanism allows this pipe to change its length. Electrical fan replaces displacer and pumps working fluid throughout the engine constantly and in one direction. Some portion of the pipe is replaced with branching structure that consist of two heat exchangers (hot and cold) and regenerator. On both ends of this structure special valves are located that connect one of the structure’s parts to the main pipe, so that whole engine forms one closed-loop. While this happens, both of the unused parts are completely bypassed.This design should have many advantages. Working gas is in constant motion and little energy is wasted on accelerating it. Gas may pass many times through heat exchangers, allowing for much better approximation of isothermal processes. Disconnecting unused heat exchangers from the rest of the engine should minimize volume of dead spaces.There are some drawbacks to. Slide mechanism allows only very small changes of total volume (compression ratio is low), and that limits engine’s ability to operate with higher temperature differences. Piston, which is part of the slide mechanism, and especially valves, are heavy and this makes them unsuited for high speed operation, making the whole engine bulky. I also except that an area of all surfaces that are sliding against each other and produce friction would be higher than in traditional Stirlings.Problems with Stirling cycleIdeal Stirling cycle (Fig. 4) consist of two isothermal processes (constant temperature) during which work is performed, and two isochoric processes (constant volume, no work performed). Isochoric processes function is only to change temperature of the working gas, and this takes a lot of energy to do so (especially if gas with high heat capacity is used). Regular Stirling engines try to minimize this inefficiency with regenerator. But when I tried to analyze this process mathematically, I noticed that even regenerator with very high heat capacity cannot store more than half the energy needed to perform next isochoric process (see lower left part of the spreadsheets for more details).Fig. 5 represents heat pump (or refrigerator) working in a modified Stirling cycle. Isochoric processes represent transfers of heat to and from the regenerator. Rest of the temperature change is performed by polytropic processes, during which heat flows to or from the heat exchangers and also work is performed. I chose to represent heat pump, instead of a engine because engine working with this modified cycle wold require isochoric processes to be performed midstroke (or transfers of heat to regenerator would have to be performed during polytropic processes, when working gas changes its temperature also due to work being performed).Note that I am using word polytropic to indicate processes where gas changes its energy both due to heat transfers and work performed. When special cases of polytropic process are mentioned (isothermal, adiabatic, isochoric) I use their specific names.Solving those problems with Carnot cycleLegendary Carnot cycle consist of two isothermal processes (just like Stirling cycle), but changes of temperature are accomplished by the adiabatic processes (no heat transfers with the surroundings), instead of isochoric ones. This has huge advantage, because when energy is added to the working gas during adiabatic compression, all of it can be later recovered during adiabatic expansion.Design I previously mentioned can easily be adapted to work as a Carnot engine. Only change that is necessary, is replacement of regenerator with the empty pipe (ADIABATIC PIPE in Fig. 2). When valves connect this empty pipe to the rest of the engine, there is no heat transfer between working fluid and thermal reservoirs. Any changes of engine volume modify temperature and pressure in a approximately adiabatic fashion. To model what happens with the engine I used slightly modified Carnot cycle (Fig.3). Just before adiabatic process end, short polytropic process begins. It is done so that loses associated with valves connecting both adiabatic pipe and heat exchanger to the main part of the engine for a short period of time can be better simulated. Heat pump working in this cycle is shown in Fig. 6.Design detailsEngine uses special valves, which external shape resemble truncated cone. Smaller base of this cone faces main part of the engine, larger one heat exchangers. Inside there is a pipe, with one opening right in the center of smaller base. The other opening is located off-center on the larger base, so it can connect to the one of the heat exchangers or adiabatic pipe (which are situated just like chambers of a revolver’s cylinder in respect to each other). As this engine engine will most likely operate under low RPMs, flywheel will have to be connected through a transmission with very high gear ratio. The flywheel will have to be quite bulky as well. This poses another challenge, as the pressure inside engine’s tubing will be higher than atmospheric, and at least space around the other side of the “piston” will have to be pressurized as well. If only the immediate surroundings will be pressurized, and gears, flywheel, electric motor/generator will be outside of the container, then very inefficient seal will have to be employed. If everything will be located inside the pressurized container, then fast moving parts will be working against dense gas. Pressure in this area ideally should have such a value, so that on every piston stroke energy is both added to the flywheel and extracted from it as to make energy storage requirements more manageable. This requirements may also be further reduced by employing some other energy storage form. And of course exchange of heat between main part of the engine and this pressurized section must be taken into consideration.Then, there is problem of heat exchangers. They can be either large diameter pipes with fins, or smaller diameter ones that are densely packed (this seems to be must popular configuration in Stirling engines). As heat transfer with the outside of the engine takes around half of the piston stroke, it might be a good idea to employ two pumps of heat transfer fluid per each of the two heat exhangers. One would work constantly to transfer heat from some large heat reservoir, the other would transfer heat to the working fluid only when it is necessary. Some another heat exchanger would have to be placed between those two circuits.And there is also a question of the piston. Basic trombone-like version could be replaced by the something similar to the design drawn in Fig. 7, where two parallel tubes, connected by U-shaped piston, are replaced by the coaxial pipes with volute on the outer section that allows connection another parallel pipe. Piston itself has then small tubular part attached which allows working fluid to pass from outer section to the inner section. This design has only one high pressure seal, is possibly lighter, but fan that pumps working fluid will probably need to be more powerful. Problem of sideways motion of the piston must also be analyzed, and it can be either resolved with piston skirts or the crosshead. Interesting aspect of this problem is that while most frictional forces in the engine are mostly independent of the engine speed, forces associated with this sideways motion of the piston increase with engine rotational speed.Another possible improvement would be making adiabatic pipe shorter than the heat exchangers, which would reduce volume of dead spaces.Engine parametersIn case of a engine that uses helium as a working fluid, has minimum volume of 46.7 liters, maximum volume of 70 liters, operates at temperatures of -5°C and 37°C with the speed of 15 RPM you can expect that it will produce 1138W of power at 8.13% efficiency.In the case of heat pump that operates at the same parameters you can expect that it will require 2300W of power and achieve COP 4.95You can find calculations, diagrams and the detailed descriptions inside non-ideal_carnot_engine.zip (it is unfortunate that Instructables do not support uploading .zip files and other file formats any more, and I have to use another website just to upload few spreadsheets).Possible applicationsI started thinking about this concept when considering applications of thermal energy storage. In more northern latitudes largest factor in domestic energy consumption is heating. So, at least in my opinion, any movement toward replacing fossil fuels with renewables should focus on this largest contributing factor. And this actually is quite fine because storing 1 kWh in a tank filled with water, rocks/concrete or simply in the ground is much cheaper than storing it inside lithium-ion batteries. And general idea behind this low temperature engine, was that some part of this large amount of energy stored to be later used to heat buildings, could be converted into electricity.It should also be able to work in reverse as a heat pump or refrigerator.

What's the best way to bend coat hanger wire, for making a DIY GameKlip?

So I discovered my Samsung Galaxy S3 supports USB gamepads.  Well long story short, I quickly hacked apart an old original Xbox controller, replaced its 10 foot xbox cable with a 1 inch USB cable, and it works GREAT in most gamepad-supported Android games like Dead Trigger and Shadowgun.  The next obvious move was to make a holder to attach my phone to the gamepad, to have a portable gaming device, like an nVidia Shield.  Now I know commercial solutions exist, like the Gameklip, but they're all designed for the PS3 controller, which I don't have. So I've attached pictures of my first two versions.  The first picture showing the regular coat hanger wire wrapped in black electrical tape.  It held the phone just fine, but it was butt ugly, because I used electrical tape to protect the phone from the steel coat hanger wire.  So I made a second one (2nd picture), using a rubber/plastic coated coat hanger, thinking it would look better, because I wouldn't need to wrap it in electrical tape. Well the problem is that I'm so horribly bad at bending wire, and at planning, and measuring, that I had to make so many corrections, that it too looks butt ugly.  It's a completely different design than the first one, for starters.  I can never think of how to design these things on paper.  I always just get a rough idea in my head, and then play it by ear as I go along.  But because steel coat hanger wire is so incredibly tough, every time I try to bend it with pliers, or a vice grip, I end up damaging the nice plastic coating, making it look ugly.  Multiply that by the number of times I had to make corrections, and well, you can see the result.  The second design is the one I'd like to stick with, however.  Mechanically speaking, it is perfect.  Two nubs on the bottom, and a nub on the left and right sides, hold the phone in place using gravity and friction.  Then the whole thing uses spring-tension to compress the left and right nubs inwards, squeezing the phone in place, but without letting these nubs get in the way of the USB port or the headphone port.  One can adjust the width and tension of these left and right nubs, just by squeezing or stretching them apart, to fit different sized phones and cases.  Finally, two support legs are left at the end of the wire to easily place the whole thing on a table. Both versions are attached to the controller in the same way:  I started with two loops, as small as I could make them, right next to each other.  Then I just bolt the whole thing to the controller through those two loops, and two holes I've drilled in the controller's memory slot.  It's an incredible pain in the ass to try and get the nut and washer in the tiny amount of space in that memory card slot, but I managed to do it twice. I want to build a third, good looking one.  So now I've gone out and invested in some proper, straight steel wire (of the same thickness and stiffness as the coat hanger wire), and some heat-shrink tubing to protect the phone from the steel.  But I need advice on how to do this properly, so that it looks good.  The only way I can use the heat-shrink tubing, is to put it on FIRST, BEFORE bending the wire.  I couldn't possibly imagine how to do it AFTER bending the wire.  But the problem is, I'm worried that my vice grips/pliers will damage it the same way they damaged the plastic coating of the coat hanger. Any suggestions/tips would be greatly appreciated!

Ancient technologies revisted - The Moon

It was always up there in our sky.It inspired artists, song writers and created some of our greatest myths including werewolf stories.But is the moon really just some old rock giving us tides and a more stable weather?NASA tells us the moon is a hollow metal sphere.Astronauts reported Foo fighters and all sorts of optical objects that no radar would detect.To say WHAT the moon is would be controversial is an understatement but the facts are out there and are being accepted more and more by mainstream scientists.When I was a kid you would have not found any scientist taking seismic reading from the moon as prove that it is hollow.Today it is a widely accepted fact as we can not produce ANY evidence that the moon is not hollow.All this however only spans a few decades of exploring and slowly accepting facts for what they are.We still struggle to accept that ancient myths and writings as well as evedince written in stone is real evidence.Mythical creatures, gods and such come from the mind of people not knowing technolgy as we do today.They got depicted often as interpretations of the real thing.Some native tribe member from the Brasilian jungle would today not be able to make a drawing or even model of a helicopter that few over his head.It would look like anything but a helicopter and shows what was really visible with a lot of details lost, especially if it was flying a bit high.So let us assume just for the fun that these ancient texts and images really show us advanced technologies seem with the eyes of a underdeveloped (technical) brain.After all, we are happy to accept a lot of other things from the same texts without even questioning.A surprising amount of ancient myths and legends speak about the time before time.Or in more modern words, the time of creation.It is always a reference to when for those "reporting" self awareness and existence started.Some scholars though say it only the time when we learned to form our spoken words into a meaningful written language.This statement becomes painfully obvious when you explore cultures that never developed a written language in ancient times.Like the natives in Australia and namy native tribes in America.Many scholar these days consider that the ancient people only developed a written language as a requirement.But not as a requirement like we might think.You can teach one person something or give the person instructions.This becomes much more efficient if you can write it down and the other person can read it.It also revent mistakes and misinterpretations.It is the number one thing allowing us advance technological.Those cultures only adapting to a written and "documented" language long after their peak provide us a story that is shared throughout ancient cultures around our globe.We can hear the same from the mebers of those tribes that still have no written language of their own today.Some of them even started to see the importance and became authors and wrote books about the dreamtime and how their people and our world came into existence.In those older than ancient stories we hear about a time of great suffering and ongoing harship to survive.As long as thier stories go back it was like that.Put into modern context and stiched together from around the world:We had hurricanes on impossible power destroying crops and dwellings but the big cities always surived them.We had winters cold enough to freeze a glass of water in minutes.It was a hard existence and survival was everything.Whenever it got too hard though the people from the big cities offered help and shelter.Our struggle with this is already that during those time humanity neither knew how to build solid stone house now had a brain capable to design a complex city.Either way the powerful people from those cities decided one day that enough is enough and provided weather and climates to allow humanity to evolve.Once pure survival no longer requires 24/7 attention you find time for other things...Then what was it these ancient and unknow city dwellers did to fix our weather and climate?If you trust stories that were told from generation to generation for millenia then they placed a huge disk in the sky emitting enough light during the night so peole could see what is going on without needed a burning torch...The simple people back then were scared and thought their end is coming because this disk made everything so much worse.Huge earthquakes, tsunamies going hundreds of kilometers into the land, vulcanic eruption lasting for months on end.Decades of cold and miserable weather from all the dust and smoke in the air.But those powerfull people promised it will end soon and that the disk will bring stability and prosperity to humans.And when it finally happened and our world was the beautiful blue planet we know today the powerful people left - often together with their cities.Left to go back to their even bigger cities in the skies and amoung the stars.This huge disk was much much later named moon....A nice story, trust me I know....But we like to say that every story, every myth and every legend has a true fact here and there.Often overstated, or simplified but still there...The more we learn about ancient text, the more we actually understand why making sure these stories survive throughout time - the more we learn that they more truth in them than we dare to admit.How important would some historial fact for us today be so that we would try to preserve this knowledge for the thausands of year yet to come?We don't even have this concept :(So try understand how important, how valuable the core of a story must be that it really surived for thausands of years???!!!You could make a much greater story about how you invented the wheel and clock or how building dams allowed your culture to feed everyone through advances in farming.All those facts got lost, only the people from the skies and the disk up there remained important...Can we really be selfish enough to just ignore this fact and state it is impossible and never really happened?The storeis place the moon into our sky at around 100-250.000 years B.C....That is if ignore one tiny detail, but I get to that soon.Science provided us with real answers and fully debunked all the mathy about the moon being placed.When it was supposed to happen our geological structure was already subject to the gravitational forces of the moon.And thusands of years earlier the samples show exactly the same, so we can stop this nonsense of the the moon being artificial, hollow or even created and placed by someone.Or can we?Thing about these ancient stories is that they tell what was happening those "before", the ones providing help and guidance "now".Unthinkable, turst me again, I really know :(But as science states over and over again: Only fact we can see and explore speak the full truth.We found parts of the truth during the German space program and got scared enough to stop.Is it our advance in technology, defence and offense that gives the confidence to go back again now?Some say yes, other say it is a necessacity to go back.If we look who holds the power and who had and still has the control about most vital info deemed to be nothing for the public we have to wonder...It is a bit like a Star Trek comedy."Look! We united, we make a team efford, we are ready!"In reality though we just a bunch of cowards playing dirty games with each other.No one really wants to be just a part of it, they all just want to be first and stay in control.Coincidence? Hardly...What would be the possible implications of all this?Even if we could ignore ancient stories about the time before time we can't ignore basic facts.A hollow moon would indeed mean that just rock is not enough to give it enough mass.Would also mean it simply can't be coincidence that it has no rotation despite all we know about planets and moons clearly stating otherwise.Excluding even this problem we still struggle.No matter if there is rotation or not, the "millions" of years of space debris of quite large size would have left real evidence up there.But we find no real mountains, no really solid rock in or around the craters.And the damn things, despite this, seems to be so hard that no impact can create a deep crater....So of course we found some discarded scientists who started to count and cataloguise all these impacts.Thanks to NASA providing highly detailed images and orbital scans an almost easy task.First goal was to figure out or at least properly guess how much mass these hits added to the moon.Most of them would have been some icy mix with rock, only a tiny amount with mostly metal at the core.Since the moon still has some sort of working gravity despite being hollow a calcuable amount of debris would have settled on the moon and not that much would go back into space.Also some of what escaped would not have escaped orbit and the moon collected it over the years with its gravitational pull.The scientists struggled at one point when they found a weird problem.Not a single crater seems to have been caused by something hitting the moon at an angle.No one up there to clean up and no atmosphere either...Statistically speaking it is next to impossible that every rock that ever hit the moon came at a dead 90° to the area it would hit...Anyway, they ignored that tiny conundrum and moved on.We have a good idea how deep the craters are and how high the rings around them are.Everyone can agree that a crater can't be bottomless, because, well, it is covered by debris and rather flat.This flatness everywhere on the moon suggests that something "solid" must be under it - at a certain distance from the surface.With a margin of error in the region of just 17% the debris from whatever was hitting the moon to create the craters matches the thickness we would need to cover a solid sphere....Coincidence I know but still interesting to know...So when we can finally admit what the moon really is and how exactly it got up there we know for sure that we modern humans were not there first people roaming the planet....Does not mean that aliens were here or that they still are, just give a different perspective on our evolution and how the earth evolved.And we can just change what everyone takes for granted...But wouldn't it be nice when in a few years some astronaut calls home and says "Hey we fund a hatch under the dust!" ?What would we say then to ignore what we already know?

Ancient technologies revisited - ancient "GPS"

This part is more theoretical but might be interesting anyway.To make this topic any interesting to you I have to assume you play with the idea of "alien" having visited earth in the past.If we check UFO sightings and map them like a nice man did for decades, then we find a weird thing appearing on a global map.It seems as if these UFO sightings are concentrated in various locations along a "grid".Some of this grid is the Ley Line system, a weak system of "lines" where certain energies act differently or where certain fields are detectable.Won't go into the magical part or why so many townships along those lines have names related to starts or constellations.Another part of the anicient GPS system is anomalies our earth provides, be it natural or "created" in the far distant past.I got interest after finding social media posts about an area claiming to have a messed up gravity in a very small area.Less than 100km away, so a nice bike ride with some testing stuff and off I went.Seeing a car appearing to roll uphill or balls seemingly doing the same is one thing, trying it yourself another.I did not notice any differences in weight or how the bike handled but I got a very weird "optical illusion" trying to tell my up is going down and the other way around.Did it in both directions several times with no change in this impression - even when focussing only on the spot in front of my wheel.time to invesigate further and to debunk some flaws other people made.Like how useless it is to use a self levelling laser level to "prove" nothing is wrong with gravity.If it is, then how would a self levelling device, depinding on gravity know? ;)Instead I did it dirt simple.Neon strings hung from lots of tree branches and twigs.If gravity is going nuts then those strings outside the affected area would hang at a different angle than the rest - they did not....Not even from a great distance, all just hanging perfectly straight and at the exact same angle.Ok, then, just an optical illusion due to the terrain after all....Last but not least I remembered my phone claims to have a gravity sensor and my watch has an altimeter and other sensors...The sensor test app did show some fluctuations but not any different to home or other places I tried.A bit more but IMHO not enough to justify any conclusion.However, my watch confused me.From what appeared to the bottom of Gravity Hill to the top I guesstimated a height difference of about 15m.My watch insisted every single time that when I reached the "top" that I was about 10m lower than at the bottom....Was a fun afternoon but I was no wiser in the end.Gravitational, magnetic and even geoligical anomalies are well mapped these days, same for undergroud lakes and water basins.Most of this data reached us from dedicated sensors on satellites in low earth orbit.If we have no troubles mapping them then it is safe to assume that a civilisation capable of inter stellar flight would be even more capable.And after god knows how long we finally even can measure the Ley Lines and no longer assume they are magical myths.All up it makes for very accurate system of navigation beacons that you can detect even if you approach on the night side.And since these locations on our continental soil as well as our ocean floors don't really change their positions it is highly accurate.If we say it is possible to use what earth, more or less naturally, provides to located any spot you like while still approaching earth from space - then what about more specific "markers"?We have the great wall, the pyramids, lines up stones from the stone age and then some things visible from space once you are in a good orbit.The ancient cities were often in what it today and already was back then, jungle.They must have stood out the same was as the pyramids - as huge clearings in the jungle with massive buildings.We also have all these nice animal figures in Peru.Too big to make sense from the ground, wrong angles to make sense from a great distance, unless you see them from above, or from orbit.All this was long shown to be coincidence, nothing to worry about or waste time on.But we learned this is not the case at all.The pyramids perfectly line up with the Bermuda triangle and ancient cites on the other side of the pond.From England to Rome you have a dead straight Ley Line and far too many are sitting right on top with unusal names.Attempts have been made over and over to use these existing references to find lost cities and more, quite often with success.We are very reluctant though to explore those signs pointing to the oceans...Finding just one of the mythical cities at a sea level matching the time period would mean that not just that myth might be true....I am not claiming I cracked the puzzle, just in case you wonder...Basically all ancient cities have mathy around them linking then to the gods, people from the stars.Even our cities following the Ley Lines are filled with these stories, be it the anient Greek, Romans or the great Kingdoms in Europe - the later all had their main residences right on the Ley line, some even on nodal points.Merlin was a great Wizard - or just some visitor with a far higher technology and knowledge of science...A very nice but somewhat very wrong theory claims the pyramids were actually build as huge power plants.You even find stories where it is (totally correct by the way!) calculated they could have been used as giant microwave transmitter to power starships in orbit like a recharge station....If that was the case then all identical pyramids, in terms of dimension would have been the same type of power station.Sadly they all seem to have only astronomical functions.Stonehenge is different, Rome is different, a lot of the old cities and temples are different.The thing common in all locations is Granite or even Diorite.Quarz is also heavy used in these locations throught ancient times.What do these materials have in common?For starters they are so hard, so durable that we struggle to work with them today unless we use diamond tipped tools.Even most carbide tools fail on Diorite...Secondly the fact they all have rather specific and organised crystalline structures.In some Indian temples this is even used to produced accurate and harmonic musical notes.If you want to build something that is certain to outlast your civilisation then you would choose these materials.Never mind the fact that the people in that time had no means to even scratch these hard rocks....A rather unusal approach to the problem started only less than 2 decades ago.Trying to measure more than dimensional properties of these creation, specifically these huge obelisk type "needles" of often hundret of tons in weight.Of course they could not really often use the real thing and to make do with smaller models they created.Key point was to match the exact type of rock from the same region as the big original, plus making sure the crystal structure is aligned in the same orientation.These guys first dicovered that these rock needles resonated at very specific acoustic frequencies.Nothing for most the spectrum but a very sharp amplitute amplification with little to no added harmonics for just a few tight frequencies.And yes, the max "elogation" was along the lenght of the needle with the tip acting almost like a resonator.The second and rather unexplainable thing was that these model sized needles also reacted to audi signals that did not came from a surface actuator but a normal speaker at close proximity.Did not stop them, just encourage them.It was not specified in the publication what higher band frequencies affected the rock but they claimed it acts like a high power amplifier for certain frequencies - with no detectable way where the excess energy comes from.If true it could mean that a lot of ancient structures we consider to be decorative could have actually been more like a lighthouse.Emitting a focussed beam of energy detectable from amost any approach angle when enterin our solar system.The thing you might now wonder about is: Why would highly advance civilisations need such beacons to begin with?This answer relates to the Apollo program - the Van Allen radiation belt, and some other strange things close to earth.The most significant other thing is our Ionosphere.Togeher they make radio transmissions next to impossible, only close to earth orbite, like where our satellites reside are in good enough reach.A long claim was that only certain frequencies can pass through these interference layers without losing too much energy or being distorted.Most of our planets emit a natural low frequency RF "signal".We can't detect them from earth though and used satellites and probes to measure and define them.Tesla's famous alien message was decades later calculated aginst these movements in regards to his location.Turned out he detected not aliens but the signals from two of our planets.Now this might be no big deal, I mean knowing it was not aliens after all, but it is in fact a huge deal!Tesla's receiver was only able to work in these impossible low frequencies that were claimed to be unable to pass through our interference layers!Much later we dicovered windows in these layers, even ways to caculate and predict their movements.It is now widely used to improve communications with our space probes and Mars missions.We still don't know if a suitable window was present for Tesla...If ancient civilisations or the gods visiting us for a while needed a way "to call home" or be called - what better way than using was is naturally there already?And it work the other way around as well.Send a strong enough and suitable signal to these structures and they would have to respond, maybe even in some audible form, no one really knows for sure it seems.My personal theory in terms of navigation and transmitting/receiving energy goes as follows and I hope you like it enough to make you own thought and conclusions:If we simply assume that certain anomalies or natural energies on earth are not just detectable but also usable it all could get a whole new meaning.Place a suitable object into an energy field and it can act as a "filter", an amplifier or as block.Like a Yagi antenna that you might find on your roof.What happens if have a theoretically endless conductor with a high frequency voltage going through?You have a very bad antenna of no use...But if you would place straight wires with a length matching the frequency you get a ton of small and powerful antennas....A bit simplyfied, I know but best example that came to mind to make a transition.If our Ley Lines and other form of natural energy phenomenon would provide energy to these ancient structures:What might happen if this "antenna" is just slightly out of tune and you "strike" it to produce a harmonic wave matching the energy going through?Right! You suddenly have a giant signal amplifier.And right again! You could actually try to send "signals" through the Ley Lines this way too.A harmonic wave would overlay the natural signal from the Ley Line and travel along it's path.Now the part you might not like at all, but it a key point of my own theory:If it is a natural energy that provides all this and we are able these days to detect these energies although we fail to understand, then where to they originate????If you poke your arm with a neeles then it hurts, poke a bit more and you bleed once you remove the needle, no one would do this for fun or even to get pleasure...Then why do we poke needles into our body, call it accupuncture and go home with such a happy face once the pain is gone???Guess you got my point already...It can't be denied that ancient civilisations already had a more than good understanding of things we onlydicovered or proved to exist thausands of years later.Even if we would exclude all godly and alien like things and just be ignorant and say that these folks knew the "body" earth" as good as a chinese accupuncture master would know your body and where to poke a few needles to heal you?If the energies are natural than our planet must produce them somehow, if you know how changes affect the planet you can "poke" it to get better - or to get much worse....Like the Butterfly Effect....You poke needle into Spain and in New Zealand you get a small earth quake....You poke a needle into Iceland and a temperature drop over atlantic makes the deveolping hurricane change curse to run out of steam over the ocean.You poke a needle into the right spot, stimulated properly and send a signal into outer space....If we can detect them easy from space, how strong would the energy level be if a burst of ALL the energy travels along the grid to combine in one single point?...How far could such a signal travel?How FAST would it travel considering no one, not even NASA dared to publish details about how exactly and what exactly was detected that matches these ancient old and till then just mystical energy lines and spots?A gravitational shockwave from an exploding star travels much faster than light....The ancient cultures of meaning knew exactly:Where the sun is in our milkyway,where our planets are at any giving time,at what angle our planets axis is, they even tracked this accurately,where exactly until recently unknown stars are within the Orion, Sirius and other constallations,when those stars where visible in the DAY or NIGHT sky,how exactly they moved when moved from earth AND how the position of earth relates the other way around,that there are Ley Lines, gravitational anomalies and more that we only learned to detect thausands of years later,about ALL the phsical, electrical and energy related properties of of suitable rocks and minerals,.....If they knew all this and we know that they did, why is so hard to believe they would have to have known that for a good reason, a purpose?I actuall don't care if they found all out themself, without knowing the wheel or the telescope...Neither if aliens, gods, people from the stars, visitors from another dimension or E.T. himself (herself, itself?) told them.But I cared for a long time about WHY humanity as a whole seemed to have forgotten all about his and how to use these unknown energies....So the final bit is not about my personal theories on ancient navigation, communication or energy usage.It is about the why it was lost...I make it a new chapter if you don't mind as it is not really about the GPS topic.

A complete roleplaying game in one post

I can't post this as an Instructable, because it's not my game at all.  It surfaced in the sorting out of my lab as my school closed. My original copy of the game was a page in Games and Puzzles magazine, but this is my own re-type of it, which I had to re-type again because the first digital copy was lost during one PC upgrade or another. The document gives me permission to pass it on (even though it pre-dates the Creative Commons movement), but I have emailed the author to let him know I'm posting it anyway.  I've not had a reply, but the page I found his address on had not been updated since 2009. UPDATE: Frank has been in touch, is happy for the game to be published like this, and is even going to send me copies of v2 if he ever finds them. FURTHER UPDATE: Frank has sent me a scan of the v2 rules, which I have added as the first image below. I thought older members might like to be reminded of their youth, and younger members sometimes need reminding that roleplaying games didn't always need a computer with a high-speed internet connection Here is the text, and I have attached a tidier-looking PDF of the same text: --------------------------------------------------------------------------------------------------------- S.I.M.P.L.E. by Frank Carver Shared Imagination Multi Player Leisure Experience Have you ever been sitting around with a few friends and wanted to play a game – but hadn’t brought the rule books, supplements, charts & tables, character sheets, funny dice, metal figures etc? Here is the answer: a game simple enough to fit on one sheet of paper, and easy enough to remember & explain, even if you haven’t got that! ABOUT SIMPLE SIMPLE is a roleplaying game (RPG), in which each player controls the actions of a single character in an adventure. An adventure takes place in an imaginary world, which may be very different from the real world. Sometimes it’s outer space, the far future, wild west or fantasy. The background from any book, film, TV show may be used, or one from your own imagination. The adventure is usually organised by one player acting as Game Master (GM), who knows about the setting and provides things for the characters to do – problems to solve, enemies to defeat, victims to be rescued, riches to be gained ... anything the other players might enjoy. Problems are solved by thinking them through, talking to the other players and the GM, and rolling dice to see if your plan works. Details of each character are recorded on a character sheet, which develops from game to game. Travel the Universe without ever leaving your chair! TO PLAY You need at least two players (more than 5 or 6 is hard work), a copy of this sheet, at least one normal 6-sided die, a pen or pencil (an eraser is handy), some paper to write on and your imagination. THE SIMPLE CHARACTER Each SIMPLE character is described by three things – Body, Mind and Abilities. Body is a single number showing how strong and tough the character is. Mind is also a number, showing how clever and aware the character is. Abilities are things the character is good at. Each Ability has a description, and a number which shows how much better than average the character is. If your character is just average at something, it doesn’t go on their Ability list. Each character starts with 10 character points, which may be put into Body, Mind and Ability. For each point put into Body or Mind, the number goes up by one. For each half point put into Ability, the number goes up by one. Abilities may be anything that suits the setting. The GM and other players must agree with them. For example: running, science, driving, casting spells, seeing in the dark... EXAMPLE CHARACTER SHEET Name: Gus Goodguy Player: Frank Body: 5 Mind: 3 Abilities: Gunfight 2, ride horse 1, drink whisky 1 Description: A gunfighter in the Old West. Rides tall in the saddle, tips his white 10-gallon hat to ladies, calls men “Pardner”, travels the dusty plains looking for bandits to catch or farmers to rescue. Likes his whisky, and wil never resist a call to a shoot-out. USING THE NUMBERS IN AN ADVENTURE To see if a character succeeds at a task, the GM decides on the difficulty (5=easy, 8=average, 11=hard, 14=very hard and so on) and whether it is a physical (Body) task or a mental (Mind) task. The player then rolls a die and adds the character’s Body or Mind and any matching Abilities. A 6 means roll again and add the result. If the player’s total is better than the GM’s target, then the character has succeeded. The difference between the two numbers gives how well it was done. Gus Goodguy has Body 5 and Gunfight 2. To shoot Bill Badguy is an average (8) Body task. Gus rolls a 3, plus his body of 5, plus his gunfighting 2, making a total of 10 – succeeded by 2! Bill has been shot, and until his wound is treated his body is reduced by 1 point. If his Body falls to 1 he is unconscious, if it reaches 0 he is dead! At the end of a game, the GM may award up to one point to good players to spend on their characters. DOING EVERYTHING ELSE Most problems should be decided by the GM and common sense. Some useful hints, though: when time is important, like in a fight, do things in one-second rounds, with the character with the highest Body going first. A character can run Body (plus running Ability) metres per second. An “average” person has 4 Body and 4 MNind with no extra Abilities. If you need some enemies in a hurry, roll some dice onto the table – use the numbers on top as their Body score, and turn the die down one when they are injured. If you like this game, please copy it, give it to your friends, take it to conventions etc If you like it a lot, why not write to Frank Carver at: The Albion Guard Games Club, 62 Tomline Road, Ipswich, IP3 8DB, United Kingdom.

The future of mobile operating system or the end for "hackers" and rooting?

For mayn years it was almost logical to get full root access on your new smartphone or tablet.The other fraction might now it as "jailbreaking"...No one really needs it unless they are not happy with they way the mnufacturer designed the operating system and features.The removal of bloat, apps the user never needs, is still the most common reason for rooting.Custom ROM's offering a different experience are right behind.Now we also have TV's, entertainment boxes of all kinds, even from our ISP's directly.The main provider for the operating system is now Google with only a few "competitors" left.Apple has a strong hold of the mobile and tablet sector too but is not really presented in other areas.Android is still open source but Google heavily modifed it to suit the needs of data collecting and security for features like banking, access control and so on.What is good for the normal user and perfect for those with security in mind can be really bad for those actually just using a device.No matter why you buy a new phone from your provider, you almost never buy it for the added apps and services.Rooting has become more and more difficult.One reason of course is constant security updates and removing possible access options for even simple things like getting USB debugging and an unlocked bootloader.People dedicated to find ways to remove provider locks, creating custom firmwares or the basic tools required to work with firmwares were called hackers.If you buy a new car and decide to modify it with a new engine, seats or whatever than no one will stop you.So why don't we have the same rights for our electronic companions?I wouldn't call it hacking, I would call it actually owning and controlling your device instead of Google letting control you - or Apple, but who cares....The other reason is dead simple: Those guys who started it all have retired or found employoment with those they fooled for so many years.Chainfire should ring a bell for anyone ever concerned with rooting.The master is gone now and only a few people are willing to take his legacy.For Asian devices the community over there is better off but for our market region right now Magisk seems to be the only option left for modern devices.The sneaky ways to lock us out....Security comes at a price, simple as.You can offer secrity for money transfers if the device is not trustworthy.Same for online streaming - you want the money for what you give and prevent that someone is able to make unwanted recordings without encryption.The list goes on with access control system and literally everything we use our devices for that involves some security.Even with the lates PIE systems Google's own devices are still quite friendly in terms of gaining root access.Different story though if a manufacturer makes full use of all the latest addition at Google's disposal.Device security no longer starts with the boot we see.It is now possible to create a hardware based tree of trust.This means any modification to anything will cause a failure.This locks out all "tools" able to read out partitions and vital data while a device is in fastboot mode.And of course said fastboot can be fully disabled as well now.For security reason a so called A/B configuration is used.Updates come over the air and are applied to the dormant system.Next start will boot the new system and then update the old one, no requirement to manually apply and update.The recovery can also be abandoned and replaced by a system using a copy on the device itself that is updated through OTA updates with the firmware.So both ways to gain official access can be full removed from the user.From there we get encryption, hash checks and literally everything working in its own user space - a full SELinux enviroment at the highest level.There are already devices utilising a lot of this and so far the only way to get any sort of insight was done by those intercepting OTA updates on a router level.And apart from quickly changing the encryption with the next updates nothing was gained.Is it all coincidence?Of course not.Well known leaks were kept open for years.Kernel updates gave improvements and closed really old leaks but never all known ways.With the retirement of the best rooting experts these holes were suddenly closed.Checks of latest kernel releases showed that there is no known vulenerabilities anymore that can be misused to gain access.And those finding new ones and making them available for us are bascally gone now.Encryptions and packing algorithms changed, same thing for the actual handling of partitions and rights.Anyone with a decent understanding of how the old ways worked will be able to figure it out with some time wasted on it.From there however the outcome is often dark.The tools needed to work with these new files are not always updated anymore.The developer simply moved on and most of the time without publishing his source codes.And the still best way to protect your firmware from tampering is to encrypt it.In the old days it was enough to sign a ZIP file with a release key not available to the public.Custom recoveries allowed us to get around this.This still works to some extent but now we also get additional checks starting from the bootloader.A modified system will be detected and stopped and a stock system will stop i a modified boot is detected.Even using a custom recovery by flashing or through fastboot is preventable now.Right now the only way for most new devices is a total wipe and the installation of an unsecure firmware with everything.As you already guessed this is to prevent now as well.So does all this rooting stuff actually concern you?Of course not!If you never had any need for rooting or no clue what to do differently with a rooted device than you are a happy camper.But your neighbour or friend might think differently.You see, I have two problems when it comes to "stock" devices.a) I have no clue what data they collect from me and what it might be used for.b) I do not like being forced to agree to terms that are endless and of questionable content just to use the damn thing.For crying out loud: In most cases it is now impossible to even set up a new device without working internet and a Google account.....

Is my book good ?

Well i hate to bother anyone but can you please take some time to read this book i worked hard on ? i spent  countless hours of my free time over the weekend developing the plot and creatures so can you please take some time out to read the whole thing tell me what it needs or what would be good i already am 16 pages into the sequel so tell me if this is good so i can post the sequel ! enjoy Times come by Alby Chapter 1- beginning It was the night I would never forget,the night.......i....the......the last night I would enjoy life. It was spring of 2017 the night air was heavy in my lungs and you could faintly smell the BBQ and charcoal smoke from cookouts that died down hours ago I could here people talking and having a good time but I think my drink I grabbed the wrong beer it was Sarah's it was spiked I never would have noticed who did it at least it wasn't her to drink it. I simply enjoyed the sky line of Chicago filled with sky scrapers and mirror like office buildings it all seemed like a Bokeh picture to me the drug is taking affect on my body I feel dizzy . I hopped on the train, it was empty as for the weather gave a good reason to walk but I needed to get home safely. In about 30 minutes I was home. I clumsily walked up the stairs and almost fell it took about ten minutes before I opened the door, I then plopped down on my bed and ran to the bathroom and regurgitated everything I ate that night. i starred at the ceiling. I saw every detail to the nearest centimeter and then blurry the specks the marks swirled in my vision and I felt weightless for a while. I starred at the clock and noticed it was about 4:00 am and cursed myself for going to that bar with Sarah I threw up all over my bed. I tried to grab the phone to call the paramedics but I fell and hit my head on my night stand. I passed out from the concussion i fell into a deep sleep a very deep sleep. Chapter 2 Change I wiped the crust out of my eyes and felt my head a sharp pain rippled thru my scalp it was a Gash about two inches in length. i walked into the bathroom I pulled the faucet but all that came out was a wisp of air. I snatched a baby wipe and cleaned off my face I cleaned my wound with alcohol the sting ive gotten used to I used to get hurt pretty bad in the army, I got shrapnel in my knee and they sent me home the first year. I noticed a dead silence on the street I thought they probably closed it off for some type of repair. I put on my white tee shirt and noticed its softness and how it fit snug on my semi-muscular figure I was in good shape for a twenty-four year old, my mom would always tell me most of the people in America are fat but I guess she loves to tell stereotypes for what they are. I put on my jeans and not forgetting the belt this time either. I snatched my keys off the kitchen counter and headed for the door. I walked outside and paused too look at the empty streets filled with litter and carnage . My mouth wide open in amazement I asked myself what happened and pondered the different reasons riot,panic,fire what could cause such a mess, I walked towards a police squad car and smelled something rancid I slowly proceeded, I instantly veered back in panic I could not believe what I saw a dead police officer lying face down with half a chunk blown clean off his head. There were pieces of it every where splattered on the windshield and door of the police car and some on the concrete. I instinctively inched towards him and thought to myself that something bad is happening and I need protection. I unhooked his holster off his waist and placed it on mine I pulled off his Kevlar vest and put it on weirdly enough it barely was messy or smelled bad. I checked the pockets of the vest and took out a pair of keys I knew it belonged to his squad car. I first popped open the trunk and saw it glistening in the sun a Ar-15 assault rifle. I picked it up and the memories of my army training it just instantly popped into my mind. I guess it applied the same here, I slung it around my back and walked into the silence. I took out the pistol put in the clip pulled the slide back and switched the safety off and cautiously held it. I believe the gun made me more nervous than whats in the shadows, I walked down the narrow street and saw it the skyline of the city filled with smoke and fire. I stood in anger and confusion my home town ravaged broken and charred blood stained the streets and walls, but why.....why....how could this... I mean what could....d..do such a thing. I walked away in the opposite direction and then cut into an alley way to piss and paused as I heard a roar I looked up and saw a quick glance of the belly of a apache attack craft it quickly zoom by and then another. I looked away and ran out of the alley and then down the street to see what direction they were heading. They sped towards the lake area and then I saw a tiny black object fall horizontally from the choppers belly and it slowly fell, then a explosion. I could feel the vibrations. the explosion ripped the lake area into nothing....nothing..but....but...smoke. My heart skipped a few beats thinking what if the next one falls in this area I quickly broke my daydream and bolted as fast as I could as far as I could until I saw a woman crawling on the concrete she was Moaning and holding her stomach. I came up behind her and asked for help. She turned on her back “ Sarah? Ohh my god sarah are you okay ?” and she held a gun in her hand a Glock 22 model the slide locked all the way back and no clip in the gun. I kicked it out of her and and sprung on her she begged for mercy “albert you have to stay away from me im turning” she saw that I was armed and quickly told me the gun was unloaded and that she was sorry she told me she would do anything just get away from her . I told her “Im not here to hurt anyone I just want to help” I starred at her beautiful figure her perfect face and thin hourglass body but ragged cloths and red eyes from crying. How and what did she go thru that could turn her into such a wreck. She got up and put her arm around my shoulder kissed me on the cheek and passed out. I dragged her to an fenced off alley where there was a mattress I put her down and sat next to her .she hugged me and began to cry she than jumped on top of me “Sarah what are you doing no we cant do this now no!” I told her I will help her but I dont think she understood a word I said. She looked at me in my eyes I could feel her touch my soul, her blue eyes glared in the sun. “i dont want to die alone please” I stood up nervously, I was concerned for her health when suddenly I heard a bang then felt a sharp pain in my leg. I collapsed in agony and saw the cause of my pain a bean bag round I looked up and saw a gas mask wearing figure he shot me with another bean bag round in the knee, from his shot gun he then walked over my numb body and. picked up both bean bag's and threw it aside two people in hazmat gear grabbed Sarah and took off her clothing I screamed “what are you doing to her!!!” they did not acknowledge me they looked at her body like they where searching for something. Her passed out figure limp as a rag doll they removed her pants then her underwear I screamed “No!! you son of a bitch don't do it ill kill you” they studied a bite mark on her upper thigh they made some type of hand signal and left. the soldiers then they came and started pouring gasoline on the mattress and her body. the one with the kriss super V took his cigarette out of his mouth and then flicked it at her it rolled of of her shapely belly and hit the mattress her body bursted into flames and she spasmed and kicked wildly. Then the man pointed it me and said in a British accent “ knock that fuckin Yankee an put em in da ACP double time, thoes hungry bastards are comin” Chapter 3 world gone mad I awoke on a bed in clean clothes and a hair cut. I stood up and walked into the hallway and noticed that this was a hospital. Suddenly a hand grabbed me. “aey where do you think your going ya damn runner rapist” I starred at him & his arrogant look and heavily customized ACR bushmaster. “get the fuck away from me im leaving what ever the hell this place is” he then sprung up and pushed the barrel of his ACR into my neck. “look if you want to get devoured by those runners be my guest buddy but dont go exposing this place to the infection” I looked at him like he was retarded “infection what infection and why the hell is the army bombing populated areas” he looked at me the same way. “ where were you 2 days ago ? There was a virus it was originally H1N1 but it evolved up to 10 times now its got Chicago by the balls and its spreading across the world as we speak turning everyone into animals devouring and ripping people to shreds and then the virus takes over the dead body and brings it back as a runner also know as a fresh undead body that has the ability to run or sometimes sprint god forbid but after 2-4 weeks without food the tissue breaks down from constant use without fuel and they start to get slow and shuffle around” my mind felt overwhelmed I wondered how my parents were doing in Dallas. “so what am I supped to do here but be a waste of space” he grinned. “well you obviously know how to use a weapon and our records say you have been in the military. you cant take care of yourself out there so we will make you part of out kill squad. “kill squad ?” “ohh shit you mean you have never killed or seen any infected yet ? that means your fresh you can be put to good use in our kill team” he told me his name was henry the specialist of his team kill team Charlie-mike. He directed me to the staff sergeant who looked at me and said “well well well we got some fresh meat hope you ready for 3 months of hard core trainin cuz this wont be easy now get yo ass in the garage and clean every APC tire the armory I think the kill teams ran over a little too much runners” 3 Months later........ the training was more rigorous than the basic military stuff a the armory where there was at least a 100 others conversing and grabbing into boxes of gear. Henry took me to the gunny of the armory where he helped me choose my gear. I picked up dragon skin Kevlar with implanted ceramic & alloy inserts. I took some gloves which I cut the fingers of. My boots where the basic digital camo color probably a left over from the war in Iraq which ended several years ago when our president simply drew the troops out. And European troops and some Russians finished off the big time terrorists soon after we heard no more from any our genocidal efforts finally payed off. I went to the weapon stand where I had to fill out a ID sheet to make sure they knew I had training with combat rifles. I chose the ACR which was in stock by the thousands as a gift from the weapon companies to the American army. I pulled all the safety clips and then grabbed a eotech scope out of a box and locked it onto the rail system of the weapon. I attached a mag pull the every one of my carbon strength reinforced clips. The gunny looked at me with a grin and we left for briefing. Chapter 4 things get messy we met up in the garage of the hospital every runner hunter of this kill force a total of 300 men and women in the huge elevated parking complex of the hospital, a general arrived in the elevator his chrome glasses shined in the evening light so did the many badges pinned on his suit which fit his old figure rather awkwardly. he had two formally dressed men with him they both had desert eagles on there side holsters but the general had a FN 2000 slung around his back. it was worn and scratched its polymer body was embedded with and insignia that I did not see so well as it was obscured by the scuffs and grime he looked at us and smiled his mouth opened and he flung his cigar off the ledge of the building he then begun and explained in a dominant voice. “there are 40 spec op Humvee's set up in formation ready to patrol the streets of Chicago you all will be in sector 6 the most dangerous sector of Chicago but no need to worry we have full fledged firepower of 4 APC's which will Carrie your kill team to your objectives take as much time as needed the runners arent going any where. you will clear the sears tower area a hot spot for runners. look all you men and woman, its time to revolt and fight back. its time to say we will not be scared, we will not be intimidated, we will win back our freedom!!” the whole complex light up with cheer. As the two men in formal wear took out PDA's and started directing people to there kill teams the first man shouted “ Chavez,Williams,buck, and,Samson go to APC #1” I quickly advanced thru the crowd to APC 1 I slowed my pace and saw its matte paint job of digital camo and its pop up dillan machine gun turret mounted on top. I pounded on its steel behind and its back door unlatched I stood waiting for the rest of my team I saw all three walking in a line towards the door I saw him ,the man with the kriss super V he smiled at me and said “no fuckin way you tha yankee we picked up in tha alley way you mad cus we killed your little runner girlfriend” I sprung towards him and grabbed his collar and punched him in the stomach then elbowed him in the mouth all the color drained out of his face. “ if you wouldn't of shot me with a fucking bean bag I would of blown your brains out back at the alley” he looked at me and with blood dripping down his mouth “i was just doing my job. welcome to foxtrot 3 by my names john samson you can just call me hunter” I let him go and he limped into the APC then another walked towards me he wore a Grey baklava and tight fitting clothing and a vest that barely covered his chest which awkwardly bulged out he walked towards me and took off the mask. She looked at m surprised face and said “what ? a woman cant be in the military” “well I..I...I just did not expect to have such a high rank personnel on our team” she looked at me and frowend “were both specialists grade one my names Kelly williams” “a heavily armored male in a hijab walked towards me playfully he came up to me and pulled off his hijab he was a African American . “hey specialist now look Im basically here to keep the moral you catch me ? I was in the navy im Ricky buckman Just call me squid now what do you want to go by kid?” I smiled “echo” “nice choice” Albert “echo” chavez I thought in my head I figured that sounds good. We all jumped in the APC while a kill team of rangers in a heavy Humvee with a mounted sentry gun rolled behind us as the whole convoy of kill force 6 prepared for battle. I thought about all my training aim for the head,short controlled bursts a shot anywhere else just stunned them. They move fast so they have to be neutralized if you get bitten or infected kill yourself with the poison capsule that was given or a team mate would do it. I grabbed a Kukri blade off the weapon rack that was provided in the APC I looked at its razor sharp edge its brushed steel surface reflected no light I sheathed it and strapped it to my leg. I caught the eye of Kelly who was fiddling around with the UAV control panel she looked at me and smiled. The APC's lights blinked red prompting us that we are in a hot zone. The APC vibrated as the co pilot took out a pack of runners with the Dillon remote controlled mini gun. We all loaded our weapons and packed up some ammo. Hunter and squid looked at each other and they bumped fists. I put a clip in my ACR and cocked it I turned on the eotech scope and strapped on my helmet and then slid on a black baklava. The APC driver prompted a alarm which was the signal that the door was opening, the big metal door slowly lowered its platform to the ground and we all got out Kelly was the last one out she grabbed that control panel and slid it into her bag she ran out and flipped the close button on the APC. We met up with the four other teams in our sector who already exited there Humvee's. A black Humvee that I never knew was in the convoy rode up and a military adviser jumped out and barked orders like some scared little dog and then jumped back in glad that he wasn't us. He positioned eight snipers on the roof who where each divided into teams of four they zip lined up the roofs and soon each team where picked up by two little bird helicopters the rest of us where on the ground either Humvee calvary hit teams or long range grenade support foxtrot was positioned on the magnificent mile at least it was magnificent. We cautiously walked down the street with another team of 6 watching our back and little birds with snipers covering us and telling us where the nearest pack is. It was empty until we got a report a pack of twenty runners where heading straight for us about 3 blocks away we had about a minute to prepare, snipers took out some and only six broke there steady aim and where 5 feet away, I drew my weapon and just before I could fire a Humvee rammed half the pack of runners over my team shot at there heads to finish them off . I stunted back and fell startled by a runner with broken legs dragging its smelly corpse towards me, my team did not even notice as they where pre occupied with finishing off the pack it grabbed my boot and pulled itself onto my chest I pushed it back and hunter tackled it and shot it once it grazed its ear he then rad up to it and curb stomped its head in over and over, like an egg it crunched under his boot he then walked towards me and picked me up and then our comm's screeched with a danger code: sector red REPEAT SECTOR RED!! this is not a drill!! squid looked at Kelly “OH shit radio the APC radio the APC!!” Kelly hastily radioed the APC and it arrived around the corner ASAP she got in and took the panel out of her backpack all the rangers got back in there Humvee's and formed up a line of vehicle's and the APC was in front we all jumped in and squid popped open 3 of the four combat hatches. We took stance and poked our body's out of the hatches while Kelly was typing away at the panel. “Kelly get us that predator drone NOW!!” “on it Echo..about.....NOW!! get ready for some boom boom boys” she said over the comm a predator drone deployed from a building somewhere and roared across the city's night sky. The little birds shot flares into out immediate area and the military advisor said nervously over the comm “formation green zone ASAP make space for one more hummer!!” his hummer screeched into our circle formation at the middle of the block intersection. We all could hear the uproar and the screaming rage of the Runners it was 9:00 PM and my stomach dropped as runners came at us from every angle swarming in between all the vehicles as we took out as much as we can the advisor yelled. “Break formation head for lane 3 of sector 5 Kelly yelled “but thats a dead end we have no where to go !!” “exactly now MOVE !!” we hastily rammed out way thru the crowd of runners it was easily about 200 to 300 runners we reached the street which was a dead end it was blocked by a collapsed building from all the beach bombing runs. We waited for 5 minutes until we saw it our doom three times as much runners appeared and headed for the convoy. The driver looked bewildered “Get ready im breaking position” he advanced the APC towards the crowd its massive tires gripping the rubble and concrete so agile and quick. He opened fire the Dillon mini gun until there was not one round left. the APC swiveled madly like a dog chasing its tail, all the blood and body matter stuck to the tire made it impossible to control. The whole interior rocked forward on impact with the flipped car. suddenly a screech and the APC flipped over on its side. the runners ignored the APC and went for the group of Humvee's ripping the rangers out that had not locked there Humvee door and devouring them. We herd the screams despite layer after layer of Kevlar and Armour of the APC. My radio started to squawk. “ Pindad Panser down repeat,flipped on its side calling in little bird for support !! bring in UH-60 shadow for medivac ASAP!” I groaned in pain the impact was hard,i could taste blood in my mouth my world was spinning. my team mates did not move they where all laying face down. I soon passed out Chapter 5 delta crimson “Delta crimson GO GO GO !!” I awoke in a sweat, I felt normal again I wiped my blood crusted face off. I leaned up and saw them. “Squid Kelly Hunter Your all alive !” hunter smiled “the crowds not givin up. Hurry mate we got to get outta this APC or crimson is just gonna have to save us” Crimson was an elite rescue squad of some of the best rescue force members in the military marines,rangers,green berets, you name em they can save you. Suddenly we heard the roar of helicopters. Then the door of the APC light up and blew of its hinges a soldier in a crimson baklava shined a light me and my team he latched two metal hooks onto our APC and then the helicopter lifted us into the air, this vehicle the best attack helicopter crafted by the engineer crew over at Hudson base they called it the Shadow because thats all it was, a quick killer in the night. A man made machine manufactured to kill and thats what it was best at. I broke for the chopper and jumped in then squid then Kelly it started to take off right before it left ground hunter grabbed the bay door and climbed in. “forgetting something ?” He threw me my ACR bushmaster which started to look like the generals FN 2000 it was scuffed and marked in every crack and crease. A crimson medivac specialist handed us some refreshments and snacks he said he picked it up at his last raid. He gave me some meds, adrenalin shots use them as a last resort of energy he said. I looked at squid who was holding his dog tag “ man echo you see how that APC flipped on us I almost crapped my pant's” I laughed at the joke even if its not funny my team needs the moral. I looked it the pilot he caught my stare. “where going to the main objective” I sighed and looked away hunter looked at me and made some type of hand signal. “hey Kelly you think we could of died back there” “easily hunter luckily the runners did not find our APC interesting” I looked over at Kelly who was looking at the cracked screen of the control panel. “hey Kelly what all did you use that panel for” “i saved the whole platoon with this thing while you where taking a nap, now its gone and base is a long fly away. The screen broke when the APC flipped. And the predator drone crashed without me controlling it” “damn, nothing good ever lasts long does it” “well echo thats not true your still alive aren't you ?” I we both smiled and when the happiness broke it was back to work. chapter 6 Raid The shadow landed on the roof of a building about 3 blocks away from objective R.R.T.R (runner ruled territory raid) our forces had to kill all runners and take back the sears tower. Kelly was stationed on the roof with hundreds of other snipers .with her barret M82 which ripped into 2 to 3 runners at a time with its large caliber amour piercing rounds. Military advisors sent Ground troops they marched the streets for the main attack on the R.R.T (runner ruled territory). Soldiers of all pact creed and faction marched side by side. the ISF (Iraqi Security Forces) the IRA (Irish Republican Army) even the CIA and DEA forces were marching along with whole police precincts including the bulk of the U.S military. This battle was inevitable and we are going to win.

The worst time of my life

If three years ago somebody had told me that I would be at Maker Faire, using my cyborg arms, watching Arc Attack playing the “Doctor Who” theme, and meeting Adam Savage from “Mythbusters”, I would have said that person is crazy or is mocking me. But I was there. With Instructables. It was awesome when Adam Savage, in the middle of his conference, yelled to me “Hey man! Nice borg!!”. “OH MY GOD!” I thought, “ADAM SAVAGE FROM THE MYTHBUSTERS TOLD ME I MADE A NICE BORG!!” But, beyond Adam Savage, the giant robots, the fire and electricity shows, the beautiful steampunk women, the good energy, the delicious food and the pictures with Daleks; the most beautiful, shocking, awesome and magical moment of the Maker Faire 2013 was when I had just arrived at the Autodesk booth. I saw the giant map of DIYers from around the world, and I realized my picture and profile were representing Colombia and I was one of the three leading makers of South America. I was paralyzed remembering all this journey, from being a complete loser without a future to that point in time and space when I felt absolutely happy, calm, and at peace with myself. It was worth it to keep fighting, just for that sublime moment. I felt like a Rock Star. Not because I was, but because Instructables and Autodesk made me feel like one. ……………………………………… When people ask me “Why do you love Instructables?” my answers are always the same: because the site is awesome, has amazing projects and great contests with cool prizes; because Instructables is the only one who has supported my DIY activities, especially in my country (Colombia) where science and technology aren’t priorities, and so on. But I never gave the complete answer. And now, after these fantastic five months as Artist in Residence, I want to tell the truth: I love Instructables because they were with me in the worst time of my life. ……………………………………… In 2009, I lost my job as Security Analyst in an important Colombian company. I thought I could subsist thanks to my junk projects and creating my own business, but almost nobody was interested on buying recycled crafts (besides, I wasn’t as good then as I am today.) And the only interested people wanted my works for free. It was not enough for a living, so after a few months I started looking for a job. Due to its economic situation, Colombia has high rates of unemployment and it’s very hard to find a job, and there’s no government subsidy for unemployed workers (sorry Colombia! One day, I will talk about all your beautiful and fantastic things, because you have a lot. But not today). Besides, when you are a former military officer the only civilian jobs you can apply for are in security because nobody thinks you can be creative; and if you are, nobody takes you seriously. Every two weeks I had an interview. Every interview ended with just another “we will call you.” It’s time to confess something to the world: at the same time, I was diagnosed with mild Borderline Personality Disorder and depression. It’s not something that “SHAZAM! You are nuts!”. No. I knew from years ago there was something wrong about me, but just in that moment I found out what I have. Just in case you ask: no, this condition doesn’t make me a bad employee, and I’m very competent in my work. No, I’m not some kind of evil psycho. Just a little bit creepy sometimes, but I always try my best to be a good person. And no, I’m not trying to look like a “dark and bizarre, Tim Burton style” character just because I want to look interesting. It may work for an artist or a teenager, but not for somebody trying to get a job in the security business or a stable relationship. I didn’t have any health insurance; I didn’t have money for any treatment and, in case I could afford it, there is a social stigma about persons with some kind of mental disorder, and no company would be interested in hiring a security manager with that kind of problem. So, I had to keep it to myself. I didn’t even tell it to my family. And my girlfriend broke up with me. So, my life was “complete.” I was without a job, love and almost without my sanity. Almost all of my “friends” were gone. I was drowning in debts. I didn’t have money even for basic things. I had to return to my mother’s house. I lost every goal, every dream, and every hope. The situation was so desperate that I seriously thought about giving up. But only two things stopped me from doing that. One was Carolina, the only friend I had in that moment. The other thing was Instructables. ……………………………………… I found the site several months after because I was looking for simple robots ideas. Then, I saw Instructables has contests, and I entered my first project (the “SPD Exoskeleton”) for the 2009 Halloween Contest. A lot of people made awesome comments about my project, and I received my first prize: the “Photojojo!” book and a Robot T-Shirt. “What? I just post pictures of my project on an internet site and they give me free stuff? Interesting!” Then, I made another project, the “Valentine’s RoboGrinch”. I was a finalist in the 2010 Valentine’s Day Contest. People around the world commented about my ideas, and my projects started to become popular being featured in other sites and blogs around the planet. When I got the First Prize on the Dead Computer Contest, I gave to my mother the netbook I won. It was the only present I could afford to give her in a long time. In my darkest moments, when I thought about giving up, I remembered I had some project on Instructables I didn’t finish or publish, and then I keep fighting just one or two days more, because I didn’t want to leave it uncompleted. When I finished it, I endured one week more, just for knowing if it was successful in a contest. Sometimes I won. Sometimes I lost. When I could get some money, I used it for buying tools or materials for the projects, instead of food or paying debts. Because I started to think that every project, every idea I was making, every instructable I was writing, was my little legacy to humanity. Probably one day I will die, but at least in some part of the Internet, it would be a proof that I made something good, something that could be appreciated by anybody, and my life was not in vain. And I started to win more contests. It felt good, because I thought “I’m a loser, but this loser is kicking butts!” With so many fantastic authors, the competition got tougher, so I had to improve my skills (and my English. Instructables was the only opportunity I had to improve and practice this language.) I became very good at making stuff with plastic trash and limited resources! Besides, without knowing anything about me and my personal situation, even without being on the same country, the Instructables staff and community were (and are) very special and kind with me. They always made me feel respected and loved. Instructables was the only escape I had from my reality. This site has thousands of users and still they had the time to talk to me, to care for me, to make me feel like part of a bunch of friends! They were the only people that didn’t see me or treat me like a loser or somebody who needed to be pitied. They were the only ones that made me feel I wasn’t completely alone on this planet. All of this situation lasted one year and two months. Instructables kept me fighting almost all of that time. ……………………………………… Finally, in September of 2010, I got a job. It wasn’t the best (honestly, it was horrible!), but at least I was working. Four months later, I got a better job as security manager of a business center, enough to start paying debts. On October 2010, I went to the Colombian equivalent of Comic-Con, using the Cyborg suit I built for the Instructables’ Dead Computer Contest. Thanks to this, a beautiful woman found me out of the crowd, because she loves robots. She became my biggest fan and we shared a big love. I never thought I could find a love like that. She was the girlfriend I got thanks to Instructables! She was the inspiration of my “Cyborg Heart in a Can”. And I gave it to her. And then Instructables interviewed me as Featured Author. I would be the first Colombian to be a Featured Author! That was awesome! In total, I have won twelve Instructables contests and two challenges. Thanks to Instructables, people of all the world know about my cyborgs and my Roboplanters. (The funny thing is I’m still feeling like the black sheep of the family!) ……………………………………… It was 2012. After one and a half year of relationship, my girlfriend and I broke up, for good (our respective problems were stronger than our love.) Besides, I was stuck at work and I couldn’t study something art or robotics related because the restrictive schedule of my job. So, the depression was returning… I was lying on the couch watching “Doctor Who” when a phrase get stuck in my mind: “All of time and space. Everywhere and anywhere. Every star that ever was. Where do you want to start?” And then I realized that nothing was tying me to Colombia and I could apply to the Instructables Artist in Residence Program. I wanted to know, at least for a few months, how it was to be in the most awesome company in this world. So I quit my job, I sold most of my belongings, I packed my Dremel, my trench coat and my sonic screwdriver, I said goodbye to my family and I traveled to San Francisco on February 27th of 2013. I didn’t come for the “American Dream”. I came for the “Instructables Dream”! ……………………………………… What can I say? How can I describe the most fantastic experience of my life, using just a few words? How can I summarize five months of happiness, learnings, DIY and good energy, when every day was an amazing adventure? I felt, after 35 years of life, I finally arrived in the place I belong. I met the faces behind the site I love and admire. You know who they are (sorry for breaking the magic but, please! Update the Instructables Team page! A lot of awesome people are not there!) I’m trying to not mention specific persons, because I shared awesome experiences with each one of you. Every one of you taught me something, every one of you made me feel appreciated, every one of you does a fantastic job keeping this site working. And I want nobody feels excluded of this post (Sherry always fights for sending out prizes on time, silently. Why nobody says “Thanks Sherry?”) Because Instructables is more than servers and computers and projects and internet. Instructables is the people. From the beginning, Instructables and the Autodesk Consumer Group made me feel like one of the team, like part of something bigger than myself. The Pizza Thursdays, the Marvelous Mondays, the Build Days, the Design Nights, became magical events for me. But it wasn’t only Instructables and Autodesk. This beautiful city of San Francisco taught me real lessons about tolerance, respect and being yourself. It doesn’t matter if you are radically different to the other people. Just be a nice person, do your job and respect the others, and everyone will respect you. I had never touched a CAD software, because I didn’t see any possible use for it in my life. And I thought it was something so complicated that only engineers and designers could use that kind of program. But then I went from 0 to 123D Design! I learned the basics in just two days and I fell in love with this awesome program, and it’s free! (But, seriously guys, try to fix that problem with the crashes. Everyone in the lab knew that when I screamed, it was because the program had a crash and I hadn’t saved the progress). And later, I learned how to use a 3D printer, a machine beyond my wildest dreams! I remember the infinite sadness the first time I went to the amazing Pier 9 (new installations of Instructables and the Autodesk Consumer Group) and thought I could never try that fantastic technology; and the happiness when Noah told me I could stay two months more! You have all the best freaking hi-tech tools in this freaking world, and you don’t need to be a NASA scientist or a millionaire to use them! This place is waiting for people of all the world, to come with their ideas! (It doesn’t matter how crazy they are). 3D printers, laser cutters, a water jet, a bunch of expensive machines I still don’t know the names of, an awesome test kitchen, metal and wood shops, even a sewing area! And all available for the DIY community! But, more than being on Pier 9 because the fantastic machines, I loved to stay here because Instructables.  My life has good things and bad things, successes and failures. But being part of Instructables and sharing moments with all of you has been the most memorable experience of my whole existence! ……………………………………… I want to say something to my dear friends of Instructables and Autodesk: if one day, for some inexplicable reason, you feel like your work is meaningless, you don’t like it’s Monday or simply you forgot what this is all about, just remember something: you will never know exactly how many lives Instructables has touched: how many persons found their true calling thanks to the projects, and how many persons found a hobby that makes their life happier. How many couples fell in love thanks to the delicious recipes and romantic crafts, and how many parents shared precious moments with their sons building something. But now you will always know, at least, Instructables and Autodesk saved one life. My life! ……………………………………… I wish to finish my post with some “Doctor Who” quote. I love “Doctor Who”, because is all about being awesome and optimistic and keep smiling even in the worst situations or despite you are feeling absolutely sad and alone. And the series has a lot of badass and beautiful quotes! But now, when I have to start packing my bags, when I have to return to my hometown where I have to pretend I’m a “normal” person and try to get a “normal” job again, when I have to say goodbye to my coworkers (that are at the same time most of the only real friends I have had in my life), and to the greatest organization I have had the honor of being part (where for first time in life I felt truly appreciated, respected and loved, and happy because it was Monday and I could go to work in a company that is making of this world a better place); there’s one, and only one phrase that I got stuck on my head; the last words of David Tennant as the Tenth Doctor when, standing alone after saying goodbye to his loved ones (and to the most awesome time of his life), his final moment comes: “I don’t want to go.” Mario Caicedo Langer Former Artist in Residence.

Heavy duty UHF CB radio antennas and why cheap can be much better....

If you not a fan of normal road cars then you might get some 4WD and go off road every now and then.There are even those doing trips to remote locations that take a few weeks.An essential piece of equippment these days is a UHF radio.In a convoy you might get away with a handheld one if the cars are not too far apart and the terrain suitable.Most peole however opt for a permanent installation in the dash or roof console.After that decision comes the hardest and often costly part: What antenna to use....If you trust certain online reviews and manufacturer claims then one thing becomes quickly obvious.If you need a sturdy and powerful antenna then you have to pay top dollar.Some come with heavy spring bases claiming to protect the heavy fibreglass rod if you hit a bush or trees branch.There is always a compromise between weight and stability.And trust me, on the right corrugations you prefer not to look at your antenna....So how are these expensive antennas made?As I don't have any own pictures and don't want to steal them from the net: Please search for the terms used if you don't know them already.To answer this let me go to the other types of antennas you can get for your UHF radio.There is the famous rubber ducky - a stubby antenna best suited for short range on difficult terrian.Then we have the fibreglass whip antennas that have more or less coils integrated or even consist of one single coil with different spacings in sections.Good for normal road use, not so much off road as they won't tolerate too much vibration, they often snap off the base screw.Most people now just ignore the short whip antennas of 15 to 30cm length as they usually only come with a gain of around 4.5-6db.I will explain later why that might be a misconception.The last ones are those steel whips with one or two "loading" coils.These coils electrically shorten the antenna.They also provide a matching to the 50 Ohm required for most transmitters and antenna cables.Usually they are designed to be 5/8 Lambda antennas.A good antenna for just receiving, like when using a scanner is not critical in length.Transmitting however means you need a proper Standing Wave Reflection or SWR ratio.For this the antenna needs to be tuned.To be of any good use your antenna needs to match the transmitting frequency.This works best if the antenna length is at 1/2, 1/4 or 5/8 of the corresponging frequencies wavelength.Also called Lambda if you look for antennas.In the good old 27-MHz days we were used to quite long antennas in our backyard, for the car we then opted for 1/4 of this - usually around 2m in length.For UHF however 1/4 wavelength already means you are down to about 16cm...Going for 1/2 is a good thing here as it is still quite short at about 34cm.Real difference when it comes to these Lambda factors is the radion angle produced.You can imagine a 1/4 to look like a huge donut with no hole, about 25° for the radiation angle.At 1/2 this will be flattened out to around 20°.A 5/8 Lambda ntenna can get as low as 16°.Imagine it like a flashligh that has adjustable focus.The light source is of fixed output as your transmitter.The lens does the job of the antenna.If you make the beam more narrow then the light intensity of a certain areas at a certain distance will increase.Means for the radio you get a longer distance your signal can travel with enough energy.This however comes at a price!Imagine you are at the bottom of quite stepp mountain and your mate is up on the top about 2km above you.A high gain antenna with a narrow radion pattern might not even reach up there, while a short stubbie with just 3db still has a chance due to the more spherical radiation.Also explain why low gain and with that short antennas work best in hilly terrain...Back to the thick ones...As you can see you can basically hide any type of whip antenna into a fibreglass rod.But most of the are as said "ground independent", means unlike your normal whip they don't need the spring or foot to be of low resistance to your car's body.How does that work?Well, exactly like these ground independent whip antennas with a spring base or metal pole base work.You know the earliest antenna was a dipol - look it up on Wiki ;)For our CB radios that means you have a metal rod or spring that is about 1/4 or in some cases 1/4 of the wavelenght long.This is connected to the shielding of the coax cable and provides the required ground for the mounted antenna.The big difference is that only too often a dirt cheap dipol is hiding in your expensive fibreglass rod ;)The complete antenna might bring over 2kg on a scale, but the actual thing allowing you to receive and transmit is a few grams of coax cable...HOLD ON A MINUTE!! Some will say now...My whip is 70cm long and my expensive heavy duty one with 9db is 2m long - how does that work with your wavelength theory??Well, it is not my theory, just a fact ;)Imagine a 1/4 Lambda dipol, then it would be all up around 35cm long.And funny enough, that is about the length of a $180 heavy duty stubby if you just tak the rod itself.Go 1/2 of Lambda and you get an overall length of the dipol of around 65cm - add the metal rod making the crew that holds the fibreglass rod and you have the common 70-75cm heavy duty antenna...Anything above this length usually is either just a long rod with noting above the 75cm mark or simple has the 75cm long dipol made from the coax cable at the top with the antenna cable going down the otherwise empty rod.Ok, I got it, either 1/2 of the wavelength or 1/4, so about 35 or 16cm long.Ground independent we add either 1/4 for the spring base and rod or 1/2 for the longer ones.And how again does it work with the gain of an antenna?If you trust Wiki then it comes down to the radiation pattern.These heavy duty antennas usually come with around 6 or 9db, the short ones with 3-4.5db.These values might give you an indication about the theoretically possible distance you can transmit but nothing about the terrain it is suited for.Common rules of thumb created by those selling antennas and radios is that you a high gain antenna on flat terrain and a low gain antenna in a hilly area.Around 4.5-6db seems to be the golden ratio here as these anteannas are equally bad for both extremes in terms of terrain options.What you really would need to know is the actual radiation patterns in a three dimensional plane.A straight whip or dipol as a more or less donut shapead radiation pattern.However, location affects this!Mounted in the middle of the roof it is closest to perfect, while at the corner of your bumper bar you will distord the donut and also block parts out with the body of your car.This is why for this type of mounting elevated antennas are prefered.Makes no sense to have a 16cm long stubbie mounted so the top is still lower than your bonnet...Any antenna with a loading coil (or several) or top load will have a distinctively different pattern.We speak of so called "lobes".If you see it in 2D then for example a 1/2 lambda straight whip will look a bit like the infinity symbol.A 1/4 Lambda of the same style looks more like two ping pong bats joined without the handles.Those with loading coils or linear arrays made from coax cable however can produce multiple, prefered lobes.Usually they are in the 4-6db range and claim to be "universal" or as "allrounder".Here you get a quite narrow main lobe of 12-16° with one or more but much shorter lobes going upwards at about 10-30° depending on the configuration.At short range, like in hilly terrain both lobes overlap while you get a dead area at greater distances.You can sometimes notice that when you are on a low level talking to someone up high.There are cases when with a bit more difference in angle to each other (in terms of height and distance) the signal jumps up a few numbers.You just went from the dead zone into the lobe ;)With just a db value for the anteanna but no details about the actual design, heavy duty antennas can fool you badly.In mayn cases a 1/2 Lambda straight whip on the roof will outperform a costly, heavy duty antenna mounted to your bullbar.This is the reason why the expensive ones are the biggest cheat - they just elevate a quite small antenna above your roof line.And since it is heavy it needs a big spring and you hope it will not break if you hit something on a narrow track.All while the thin stainless stell whip with the cheap magnetic base just flexes under all obstacles with no damage at all.Plus, if you really get into the thick jungle you can just take the magnet off until you are through LOLWhy is a SWR and power meter still an important tool to invest into?Those remembering or still using 27-MHz radios only know too well why you need a proper SWR and power meter.With the lenght of the antenna at these low frequencies and affecting factors new the antenna proper tuning is a must.The bandwidth of the channels also means you have to tune the lowest and highest channel so the are basically even, anything else and the old guys would scream "UNACCEPTABLE!" ;)Especially it you want to get the last out of your system without going illegal.For some reason we accepted the claims that an SWR reading of around 1:2 is fine and acceptable.Most of the radios lower the power output to protect the transmitter if the SWR goes to far out.Allows for simple mass production of antennas with fixed cable lengths that are usually well overpriced.The most expensive bit is the cable itself here...I had no time to build an analog SWR and pwoer meter that works properly on 27 and 470MHz, so I ordered cheap SW30 from China.With that I first checked my little collection of antennas then those of some of my friends.This includes everything from short rubber duckies over loaded and straight whips to heavy duty models.One thing that was obvious right away: most are far away from an SWR readin anyone with a 27MHz groundplane antenna on a long mast would accept.And only one heavy duty antenna had a SWR readin of below 1:1.6 for channel 1 AND channel 40!That one was relatively cheap noname brand.With that sorted I decided to tune at least my steel whip antennas.To my utter disappointment they were all just a tiny bit too short - a thing that would have caused a proper 27MHz antenna manufacturer to to keep a large stockpile of his antennas...I had one though that was longer than needed.And before you ask: Yes, I tested them on both my elevated bullbar mount AND a direct mount on the roof rack.Did not change much for the bad ones so I ignored the mounting position for the tuning.I checked the power once for both channels on my prefered antenna and got 4.4W.Mind you that one has a SWR reading of 1:2.2 and will no longer be used as I can't be bothered to make it longer.For some reason I thought I check the SWR and power everytime I cut a bit off the antenna instead of just watching the SWR reading.At original length I had a SWR of 1:1.9 on ch40 and 1:1.75 on ch1 with 4.6W.I kept trimming down by about 2mm increments until I got an even readin of 1:1.07 on both channels.And with every trim the power went up a little bit.I have a friend that is or better, was just at the brink of being unable to reach from my driveway when he is parked in front of his house.A radio check after the tuning revealed that instead of coming with a lot of static noise and sometimes cut out I got a solid reading of 2 on his end with a much more acceptable level of noise.However, I still struggles as badly to hear him...Funny thing is that test was with just a plain and straight whip of 1/2 Lambda, in my case the tuning resulted in a length of 38cm from the base of antenna screw to the tip.My fancy 9db high gain antenna that is just over 70cm long did not even reach him while I could hear him slightly better than on my tuned one.Changing the mounting to the roof rack gave me a clear reception and a signal strength of 4 at my friends end with no noise.Elevation and nothing around the antenna does matter...After all this, would I still bother to buy a ready to go antenna for 470MHz?Only if I had to.Getting some RG58 cable or re-using it from on old antenna is cheap enough.A standard screw mount with a grub screw to hold a steel whip sets you back less than 10 bucks, from China even cheaper.And most will find a soldered on connector on the other end of an old antenna to be salvaged if required.If you don't have any sring steel wire of about 40cm length then think out of the box ;)The packing of pillows and such often come with a sring steel wire to make the plasitc floil keep its shape, some old suitaces have thicker wire doing the same.And if you ask nicely you might get a bristle or two for free from a street sweeping machine at your councils depot ;)After all we only need a maximum of 40cm to have enough left to trim and tune down.What is left to do?Of course some distance tests to check how well such a simple antenna really really works in comparison to commercial models.I only have one 9db antenna and will check it first to see if on flat terrain there is much difference in distance for transmitting.Unless this difference is well above one kilometer I will not bother with a high gain antenna like this anymore and instead opt for a longer mast and 1/2 Lambda.Another thing on the to do list to try a ground plane antenna with topload to squeeze the radion lobe down to under 15°.The resulting antenna would be quite short here and using an elevated mast is a must have to get over roof level with at leat a few wavelengths of distance to the roof.I guesstimate that an optimised antenna of this style should result in a distance increase of about 10-15km of flat terrain while being utterly useless in a hilly areas.Plus, such a design is not really suited for a vehicle going fast on a freeway, so it will go on my house instead.

Tesla's earthquake machine - revisited!

Nothing is better to beat isolation boredom than a good science puzzle.It's been centuries since Nicola Tesla was claimed to be responsible for a minor earthquake caused by one of his inventions.We can be quite sure the actual earthquake was just a coincidence that happened duiring his experiment but still...Inventors and scientists alike have tried to figure out how his appearently small and simple device could have caused effects that can be felt by people.Now it is time to reveal a possible way how Tesla might have done it.Harmonic vibrations are what cause structural things to swing, a reason why soldiers will never cross a bridge with the steps in marching sync ;)The famous London bridge was a modern example on how seemingly randomly generated pushes by pedestrians create one syncronous motions by all of them.You can replicate the effect with a rooling board that has a bunch of metronomes placed on it.Set to the same pace they will start more or less out of sync no matter what you try.But after a few minutes the moving board brings them all in perfect harmony.The above examples and a modern vibration speaker made me think...Tesla used terms like "airspring" and "harmonic coupling" to describe how his machine worked.We know Tesla did not use written notes and that his understanding of science was a bit different.Magnetism wasn't new to him.My proposal for anyone to try is this approach of his earthquake machine:We use a T-shaped housing with a mounting plate at the bottom.Inside is a hollow tube construction.Either side of the T in the top is an electromagnetic coil.Polarities of the coils are identical.In the downgoing pipe we have one magnet mounted at the bottom and another, smaller one in the top - the middle of the horizontal part of he T.Between them is a cylindrical magnet.The upper and lower magnets are selected or machined to keep the moving magnet centered.Preferably in an equal way, meaning the weight of the moving magnet should be compensated for by the other two magnets.The tube shall be providing a tiny air gap around the magnet - enough for a free movement but small enough to provide some air resistance.We created the airspring ;)At least if the tube is properly sealed.Theory of operation:In a vibration speaker we use the weight of the magnet and housing to transfer soundwaves onto a surface.This is a forced coupling that relies on the weight and inertia of the speaker assembly.A sinewave fed into our linked electromagnets will cause the magnet in the tube to move up and down with the amplitude of the sine wave.Electronics side of things:Tesla was a genius, I am not, so I need to cheat a bit now.With the moving part solved we need a way to syncronise our coils to the movement we need.In the most basic form by a simple sinewave generator and audi amplifier - helps to create 4 or 8 Ohm coils ;)However, to make it work in harmony we need one or two hall sensors.The sensors have two functions.Firstly they help to provide the right amplitude for both polarites to get a really even movement from the magnets neutral position.Secondly they provide the feedback to find the harmonic frequency(ies).Like the push-levitating platforms we need a PID control for the coils.The reference comes from the hall sensors like in the platform.Calibration needs to be done on a rocksolid surface.The calibration ensures the magnet will always move in a perfect sinosodial motion - in sync with the coils.In normal operation the hall sensor(s) will monitor the difference between set value and reality.The difference is used to adjust the frequency in small steps.Operation requirements for the electronics:During a frequency sweep the required amount of energy required to get the set movement of the magnet changes.The closer the frequency gets to resonance the less energy is required to push or pull the magnet.Like your kid on the swing.You would try to push when the swing is at the lowest point, you wait until it is just about to change direction ;)The sweep can locate one or several resonating frequencies depending on the set frequency range.The one causing the lowest energy requirements is usually the best.With the resonance almost figured out the electronics now start a fine sweep near the found frequency.From then on the frequency is adjusted to track the point of lowest energy consumption through the PID control.Detailed explanation:With the surface the device is mounted onto starting to swing the magnet becomes weightless at resonance - every time it reaches the top or bottom end of the swing.This means we need to adjust the sinewave so the coils only provide a push right when the surface starts to move in the other direction again.We also need to make sure this push is short and ends when the surface swing together with the coil push moved the magnet to the bottom - the surface push shall keep it here in freefall so to say.In theroy short ramped pulses would be sufficient here.Limitations of the design:As we still have no clue how Tesla create friction free air springs and can only guess how he found and tracked the resonant frequency we face several problems.1. The possible amplitude or lenght of the vertical tube is limited by what the coils can provide in electromagnetic field strenght.The need to be able to pull the magnet from the lowest point as otherwise the frequency sweep is very difficult to accomplish.2. Weight and lenght of the magnet.Ideally you want the biggest cylindrical magnet you can find.Realistically you need one that has a weight the coils can handle properly.No use having a 2kg magnet if then you need coils the size of door holding magnets.So going a longer and thinner might be the way to go.I found a ratio of 1 to 5 suitable, 1 to 3 still works but causes a lot more sideways push on the magnet and through that actually more friction than a longer magnet.3.Ventilation...You will notice that at very low frequencies there might be a "delay" caused by the air pockets either side of the magnet.If you can't ge a suitable air gap between magnet and tube it is often better to have a snug and friction free fit and to add venting holes either end.If the above three points are addressed and matched properly it is literally like you pushing a swing - the limit is the energy you have to push.Good thing is that we don't need to support a circular motion ;)That means the device is mostly only limited in what is possible by the electronics and code.More severe and vital to consider is the last part:Placement limitations:Imagine you want to test the device on a vertically mounted beam with sturdy support either end.The first harmonic would cause the center of the beam to swing but also means the ideal placement of the device would be dead center.In the center the device can support the movement in an ideal way.Place it half the center distance to the mounts (1/4) and the push from the device is far less effective.Furthermore you risk adding sub harmonics thanks to the uneven pressure on the beam.If used as a subwoofer to make your wooden floor shake during the action scenes of your favourite movie you would of course aim for a more hidden placement that would require to find a harmonic frequency that causes the desired effect in the right area of the floor.As a "destructunal" device you would need to find the resonant center of the structure and the frequency where this structure is able to transmit and amplify the motion throughout everything that is structural.Makes it quite unlikely to work as an earthquake machine but still can cause some interesting effects.Ok, if all this relatively easy to accomplish with some cheap electronics and a 3D printer then what about reality and physics?Before you go overboard on the testing and coding try a simple surface or vibration speaker with a suitable amp.Don't use the suction type thingies that use batteries, go for the bare driver (speaker).The amp shall be able to produce and work at frequencies down to below 20Hz.Sounds impossible but I had good luck with dirt cheap 25W car amps that have a 3.5mm audio input on top of the stuff for the car stereo.Most phone with a real headphone output are capable to be misused as a frequency generator.Mount the speaker onto a suitable testing surface, preferably centered.If you happen to have one of these tables with a glass sheet as an insert you can cut a plastic or steel shet to fit in there and add some window sealing tape to act as a cushion.Start at about 10kHz and adjust the volume so you can still tolerate the noise.Move the frequency down and you will notice that at certain frequencies the volume seem to go up quite hard.These are resonant frquencies that cause harmonic waves to form on the sheet.The lower you go the bigger the "spacing" between these waves become.When you found the one that causes a single wave to form on the shet in a suitable direction you will get a rather violent movement of the sheet.It will be required to crank the volume up the lower you go with the frequency.At around 50Hz you should hear this a an annoyingly loud humm.What works with a speaker works even better with a dedicated device that can accomodate for a growing amplitude on a surface and only uses pulses at the right time to move the weight around that causes the push.That means we can only fully utilise our device in stuations where we can match the device capabilities with the structure or surface in question.It is not hard to destroy a pane of glass with a surface speaker and the right right frequency but much harder to make a complex structure vibrate as intended.A very rigid structure with measures to prevent the swinging of supporting structures, like a building, is unlikely to fall in sync with the device.Ever seen these rope or banner swingers in action?They can create amasing shapes by their harmonic movements.Imagine how the rope or banner would look like if there were lots of overlaying swings at different frequencies - that is what you wuld have to fight and eliminate.Fear chamber anyone? ;)Subsonic vibrations are quite easy to do with such a device.And some people say that certain low frequencies make us feel unwell, even haunted.If your house is made from plasterboard and wood then why not transform a wall or the floor into a subsonic speaker?Imagine your next Freddy Krüger night with friends....Crank the volume up every time it gets scary and your friends won't know why this fun movie suddely makes them feel so scared LOL

Ancient technologies revisited - Ancient math

You can not have technology without math a fact not too many people would deny.At a certain level you just need a common ground to get from an adie to reality, even if it just a simple measuring tape.When it comes to math we have two major players in the game today.The metric system and then what the other people use ;)Jokes aside they both have their merits and they both come from similar origins.What they both lack though is literally anything that is not a straight line.As soon as it comes to something round, harmonic, free flowing or just with a complex geometry we utterly fail.It is like running aorund the barn, climing up a rope to squeeze through a thight hole to get inside.While all you had o do in reality is to open the damn barn door to get in ;)Ancient cultures used different way to tell the time of the day or day of the year.And when it comes to defining lenght that had everything but a common ground.For some it was how long some piece of wood was.So you want a plank of "4 meters" but order from someone out of town - his "4 meters" might be less than half of you need.Despite all these local differences though they managed to build and create with astounding accuracy.To calculate the movement of your solar system and other stars you need quite complex math - today.In ancient times people were able to just this without a compunter or wasting weeks or endless calculations....How did they do it?Nicola Tesla had a glimps of how nature really works.Despite never making any real documentations to create his invention he made one big exception.The circle of math.A simple thing on paper with lots of lines, numbers and spirals.You can find several copies and remakes with your favourite search engine, I prefer Duckduckgo.He used this circle to promote new ways of doing math in lots of schools and universites.With great success I might add.Sadly all this ended when he was discredited and died as a poor man.So, what then is so different between our modern math and ancient of nature's math?We are based on the decimal system mean we use 10 numbers for everything.Our first computer only knew two - 0 and 1.A bit later they used not just bits but also bytes and words- 8, 16, 32,64, ...If you break all this down then it comes down to evolution in terms of how in netures you go from one single cell to a complete human being.One make two, two make four, four become 8, 8 become 16, then 32, 64, 128 - you see the computer here and why it is more efficient that the math we learn in school?A computer does not count to 10 and start over...Our current math uses shortcuts and walkarounds to get to the finish.It made a lot of sense in the early days but has certainly long reached the limits of use.If we understood that a computer needs to go from a single bit to a byte like nature then what about the rest of the numbers nature uses and that most likely our ancient cousins used?To really explain it I need to involve our alien friends again.If we agree they would be resonsible for all things from UFO's, over technology and down to building entire cities:Someone would have to know about it and most like have or had contact.Ancient texts more than confirm all this through myths and legends.Now imagine you would like to influence the evolution of an entire race ove thausands of years.How could you make sure they reach a very high level but will never be able to "break the seventh seal" to reach your level?Of course in a way that this civilisation would never find out or consider...You limit its capablility to understand math!Despite having the solution right in front of our eyes from a single atom, over a ceel multiplication down to sunflowers and vortexes - we only march in 10 digit steps and won't ever consider to just dance aorund with the music playing...It really makes no sense to use 10 numbers!The day has 24 hours - 2 times 12, 12 hours for the DAY 12 for the NIGHT part.Eggs come in a dozen or 12 again.Not even the moon is "digital" and ancient calendars were highly accurate while our way of defining days weeks and such resulted in a total chaos requiring complex calculations.In ancient times it was all beased on how nature does it.The gregorian calendar changed this and if you check for the "excuse" why we suddenly had for forget all about lunar calendars you might be surprised.Fair enough but how could you convince an entire civilisation to forget all about real math and learn something way to complicated?USE YOUR FINGERS! ;) Yes, by pure coincidence our math system is based on how mand FINGERS we have.Not hands, not eays, not legs, fingers.Literally any other part of our body would have made more sense, at least you can get from 2 to 4 then to 8 and soon realise you are one with nature again.Simple, genius, unbreakable - show me one little kid in school that never tried to use the finger to do help with math....How many number does nature use then?Just nine.And for good reason there is no zero as we know it.The scam works so perfectly because all that was required was to teach us to not jump from 9 back to 1 but instead to add a zero to make it 10.Every time we go past the nine in the sequence we add a 0 and once that is done we add a diget and make it a 1 again.As a result and with no escape from it our math creates numbers that go bigger and bigger until they are too complex to handle with just our brains - we get the help of a computer using a similar flawed system that is at least faster.Nine numbers only - how do you use them?You can't apply our understanding of math to a system that does not know zero as we do.But I will try anyway in the best way I can.Take the computer sequence again: 1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, 2048, 4096, ...There is a thing often just refered to being a party trick.It is the simplification of a multi digit number into a single diget one.In reality though a reamins of our knowledge how math really worked.You simply add all digets and if you still get more than a single one you repeat until you have just one.Let's try to reverty our embryo back to how nature created it b using the above numbers for this simple trick:1, 2, 4, 8, 7 (1+6), 5, 1, 2, 4, 8, 7, 5, 1, 2, 4, 8, 7, 5, 1, 2, 4, 8, 7, 5....I guess you see the pattern by now ;)Try for yourself!It always breaks down to 1 2 4 8 7 5 ! And if we have no real zero then there are only three numbers left: 3, 6, 9 .If create a circle and instead of going from 12 to 12 like on a clock you go from 9 to 9 you have the basic circle model.From the 9 on top go to 12345678.A pie with 9 slices if you need helping marking, but you can just devide the circle in 40° pieces.Draw a triangle between the 3, 6 an 9 - it should almost look like a sideview of a pyramid.Now draw lines in sequenc with the remaining numbers.Go from the 1 to the 2, then to the 4 and so on.Looks rather symmetrical with a "twist, like butterfly wings if you like.You can perform all basic math with just this circular concept.You only need to know how 3, 6 and 9 have other "meanings" and that there is no zero.Too bad we are no longer wired to think like this - but you could learn it (again).Higher math seems to be impossible though.Oh! Why no zero you ask?Well nature does not know "off" or nothing - all start with a single thing and in the end goes back to just that.Nothing is wasted...If you now would try to implemt PI into our circle we could try it dead simple.We multiply it with the numbers of the circle and add the result as a vector from the center through the corresponding number.If we would now connect the end points of these vectors and interpolated the stuff between them we get a very nice spiral.As we have no zero we also have no 10 and seem stuck at 9...But 10 times PI over the 1 still gives us the right result...In either case you could now enlarge or shrink this sprial any equal (x-y) way you like and the only thing changing the true result is the lenght of the vector.For a circle you don't care if the diameter is 2 meters or 5 kirdigs, you only need to know the vector - the definition of lenght relates to it, PI....Ok, but how could you do harmonic things like the change from day to night or a soundwave?Look to asia and simply draw the Yin Yang symbol insde your circle.Preferably rotated so the two small circle are orientated vertically.Going back to our simplification of the large numbers but using the remaining there:They are very special as they from a triangle - the proximation of a cricle with just three lines.Take any multiple of these numbers and you always come back to them through the above decimal intergation process.And it perfectly goes along with our nature.(Keep in mind real values like time or meter are just vectors here!)12 hours come down to the number 3, 24 hours turn into 6 18 hours into 9...If noon is 9 you would have a pretty nifty way to tell time precisely and the 3 and 6 would mark the turning points - or amplitude reversal....And if you now dare to color in the Yin Yang symbol slightly differently you end up with two sine waves that cancel each other out ;)Use Yin and Yang at the right enlargement (vector for lenght, time) and turn it to the correct number(s) (rotational vector) and you could do complex calculations with pen and paper that are accurate enough to build a ball bearing from the drawings and measurements - and bearings have tight tolerances.Go further and explore how our natural sequences like the Fabanucci Sequence or just the golden ration can be placed correctly in the circle and how it changes and simplifies relationships ;)Suddenly it becomes clear why our know laws of physics have such simple equations to explain them.The all deal with just linear things.Becomes painfully clear when you try to do math for a pendulum.Put down to the pure basics it eventuall becomes clear that weight does not matter for a pendulum (ideal), not even how great the amplitude is.The time it needs for a full swing only depends on gravity and lenght of the rope.....A force and vector....We did realise this at some stage at university but only after going painfully long hours of calculating all sorts of things to distract us from this simple fact.With the claim that it is needed to fully understand it LOLWe can't find the missing laws of physiscs because our math is flawed and does not allow for harmony and resonance - it is not a circle, it is a line getting longer and longer.If we do find them we will either re-invent math or use the most complex formulas you can think of to get results.Ok then, but why was this math secret hidden from us?Once you realise that you have 6 numbers representiong "evolution" or "progress" and 3 numbers that define how it all cycles in sync and harmony you can help but wonder how far this system goes.Nature and the universe is everywhere from sub atomic size to our galaxy...What drives life or evolution? Energy....Which means 3. 6. and 9 stand for the three universal forms of energy and their sum at the same time.Remember! NO ZERO, Remember! Yin Yang, no end, no beginning, always equal, always opposite.Real power comes from REAL knowledge and what you make with it.Is there an easy way to re-learn this forgotten math so it can be used for things as complex as calculating how a comet travels through space?Not really as we would first have to forget almost everything we know about math in terms of calculations with numbers result in more numbers.What we can do thoug is open our eyes and observe.Nature is all around us and we just need to learn again that nature knows it best.When you see a pretty flower look behind the flower, see the symmetry and harmony in the design.See how the number of petals relate or simply start counting with sunflowers to decipher why this design of seed placement is so perfect.The more you really see the more you will understand how it fits together using numbers.We had huge cities long before we lived in caves if we can accept that humanity is much older than what we think we won't reject true math anymore...

Does the magnet motor really work and keep spinning?

See it as a last hurray before the forum here disappears ;)For ages we have people claiming that they managed to build a working magnet motor.Basically not even a perpetual motion engine but something with enough energy output to spare.As soon as they surfaced to make it all public the vanished.Most say they only vanished because it was just another fraud as those things simply can't work - physiscs won't allow it.If that was really always the case then why did some of these people AND their families disappear after till publishing details and being active in their communities?Either way: If there is a will then there is a backseat - or so they said in the 70's ;)People are still willing to fall for every foolish plan they can find on the net, waste their money and find out that, well, it just won't work.If you dig long and deep enough though you get a glimpse of what really is possible without violating our laws of physics.And yes, done and applied properly even a magnet motor is possible.The do's and don'ts of trying to build a magnet motor:Once you got hooked you have to start somewhere.Usually some V-gate or similar that ALMOST worked for you already.Anyway, you will have to encounter the appearently only reason why these motors won't work rather quickly.It seems impossible to provide accelleration without having at least point in the cycle where the binding can't be overcome through inertia or mechanical trickery.So the first thing you really need to learn is to forget what you already know!Treat magnets like a think you never knew at all, something rare and very special.Don't use your schoolbook knowldege or what you learnt at university - only use what you discover yourself!!!Make your conclusions no matter how wrong they seem - you will find out soon enough if something was flawed.I, for example, "wasted" endless hours when there was nothing on TV.Just some good music running and playing around with my magnets.Adding metal strips, filing them down, seeing how they react at different angles and distances to each other.Once you are at the stage of getting over this last bit of forces that ruins it all you need to learn how to think totally out of the box!You can't see the magnetic field lines, can't really use magntic viewer foils on the running thing - you have to try things!Take 5 magnets and create and array with a very strong pole on one side and a very weak on the other - realise that the manetic field lines don't care whether or not they go back to their own magnet!See for yourself how strips of metel from some old transformer core will provide a pathway for those field lines.See for yourself where the "threshold" is from just "shielding" a part of the magnet to "re-shaping" the field itself.See for yourself how a magnet that you bring close to one pole also affects the opposite pole of the "attacked" magnet ;)And did I already say you should try to forget what you think you know until you could actually check it and all possible variations yourself? ;)Butter on the toast....For mostly the reason to keep it shorter I just assume you tried to build something based on the classic V-gate motor and that you found this topic somehow...For other motors most of what comes now still aplies in one way or another though.Binding:I speak of binding if a motor has one or more points during a full cycle where it gets stuck.Not just a bit of attraction, enough to ruin the entire motion.There are two forms of binding forces that I identified as important.1. Opposite poles.2. Equal poles.Just means your binding is either caused by too much attraction to move further or that the next (set of) magnet(s) repells too much.Either is bad ;)Redirected forces:It is a bit impossible to only provide a force in the exactly needed direction.For example when it is more displacement forces driving the wheel - going more sideways than in a true rotional motion.Means nothing more than that a lot of potential energy is literally wasted.Shielding:You can't shoild magnetic fields!I still use the term to indicate that I am "wasting" a part of the magetic field - I don't want this bit to interfere with operations.Flux directing:Or fluxing...I use this whenever I want to affect the shape or reach of a magnets field.E.g.: by adding a rod to "extend" one pole or by providing a "shunt" strip between two magnets.A way to get field lines where they are needed most.So much for the basic terms that might pop up from now on ;)Before you can worry about lost energy from redirected forces you need to overcome your binding points.This is only possible through shielding and flux directing!Of course it also includes the possibe use of arrays to create a field with a specific shape.Let me try with some classic examples you might have faced already:Where your V changes from wide to slim you always get stuck, so you did it again by using two V's in line.Hoping that you could use what one V has in excess to overcome the binding on the ther side.Nice thinking only you forgot that your max power output is about half way through the V ;)So you realised this and added two more V's on your roll with a 120° phase shift.Does much better now but still prefers to bind no matter what you try.So what went wrong?The approach did ;)You compensated for a binding force by wasting what you have in rotational energy - to say it simple.You might have tried some mechanical lifting and flipping as well to get closer but never close enough.Our first array....By now you realised that the junction between wide open and really narrow ruins your motor.Check where the thing stops without the next magnets in line.Then check the opposite arrangement and see where the next bit would stop the thing.This is your binding area.Mark this area.Now test where your machine creates the most pull or push to get it going.Do this by finding the strongest starting point.Mark this again.Now take a look at your markings!You will see a angular relation.E.g.: You max push/pull is 50° away from your max binding point.This angle defines how many parallel V-gates you need on your drum.You want then arranged so that whenever you have a max binding point you also have a max push/pull point at the same time.This is you basic V-Gate array allowing you compensate for a lot just by using a better design.Or second array....We now need a way to compensate at least a little bit of the binding forces by redirecting and shielding some field lines.If you like fairy floss then grab some ;)We face the problem that we use a displacemnt force to keep things rolling.Fairy floss on a stick can help to visualise ;)Grab two sticks so their stick end comes out either side of your fist.Do the same with the other hand.Having two colors helps as well and gives it some flavour.Try to align those double cones so they create areas where their forces would cancel ech other out.Meaninf for example when one north pole is close enough to another south pole to create a flattened field.You realise soon that angles are not really that relevant here, only distance ;)You can cheat by adding some (smaller but strong) magnets in little arrays between the closed and open ends of your V.Keep the distances from the previous power tests in mind though!!!For example if the closed end would just keep pushing with little binding due to having a long magnet bar on top then you focus on providing a path where the adverse push from the open V is mostly compensated.Or third array...We need some balance in the system now, so why not use magnets for the weights ;)You want to place them so they increase the push/pull forces!Helps to have a big collection of various sizes and shapes....Please also consider strips or bars of silicicium rich steel (transformer cores) to brigde from one magnet to another to get a good balanced system or just adding short pieces on the underside of magnets.Ok, where are we now?We have a phase shifted array of 3 to 6 V-gates.We have it properly balanced and still use these long mangets as the driving bars on top - or even multiple if you have more than one V per array part.And that thing is causing all our binding issues.....Common solution is now to just lift the offending bar up or to increase the distance until it can provide force again that we need.Unless you are already an artsist for building you own little steam engines froms cratch it is the worst possible approach.Creates too much friction, uses to much energy!We think we are almost there.....We can't waste ANY energy until we figured out how to get more than enough of it.A mechanical gear system is far from perfect but offers precision.A simple push rod solution works well too if properly balanced and the mechanics allow for a smooth operation.I leave it up to your what you prefer.We can't just change the lenght of our magnet bar but we can cheat - a lot.One good option to check for yourself how a magnet if a fixed rotational thingy reacts when you spin a magnet close by.Even with really good bearings you will realise the binding forces between them are not equal if you keep the same distance while rotating.Now re-think your engine desing - I know it hurst if ou realise now your magnet arrangement wasn't ideal.Do you have a north-south bar on top of a V with one row of magnets facing north and the other facing south?Really I am sorry if you do but it is not all lost unless you glued your magnets in place as a permanent solution.You can leave it if you wish but it might be harder to apply the required cheats - there is ways if you look good ;)Why a V-gate where both rows of magnets are orientated the same way?It is just easier and more flexible as you then can focus on the driving bar(s) ;)Let me explain the difference as I see it:With a fixed north and south pole on your bar you seem to be able to use "more" of the magnets.And it seems to be the logical way at a first glance.But now that you learned and discovered so much yourself already, ask yourself:Does it really matter if there a north and south pole available on the bar?Wouldn't two rows of north facing magnets with matching magnets on the bar to the same things?They would....And in such an arrangement we have almost endless ways to "cheat" physics as we know it.Especially if you have two V's per drum and have one facing north and the other south ;)For the standard single V the trick is to rotate the "magnet bar" in a controlled way so when the binding forces of the V are max the forces the bar can apply are minimised.You can see that nicely if you manually rotated the wheel and watch how the bar reacts to the field.At some points it wants to push, at others pull and at still others it would love to just flick over - use this behaviour in your rotating mechanism!You want to keep the max possible forces for the longest possible time and keep the flicking over time in sync with the drum rotation.Look up on the many ways to do a flipping motion by mechanical means to see how you can best implent one into a rotary action.If you were a really good observer during your experiments you now realise that you start to also deal with friction and mechanical losses and counteracting forces.We can not reduce all of them to zero by simple cheats and mechanical solutions.Whenever we try we must do this in the most efficient way possible - even if it means cheating on our own constructions.Remember playing with the magnets to see how they react at various distances to each other and ferrous metals? ;)There is a fine line between too much and too little ;)Try for yourself on your whell with a simple bar mechanism that allow distance adjustment.Do you really get mor "driving" force the closer you get with the bar? ;)Where is the point between effective force and you needing too much force to keep the bar at this distance? ;)Do you notice how the distance affects the forces in your binding areas? ;)Cheating the cheat ;)Now that we have to find the opimal distance for our bar to avoid changing this ones as well on a constant base during the rotation, we should see how to make this the least energy wasting.You need some sort of counter balance for your mechanics and it would be nice to somehow affect our bar magnets so we don't need to much mechanical energy to make them rotated and flick over.Why not use a drum around them ? ;)When you need a reduced force you can have a metal (ferrous of course) roatate in place.As a drum you would just cut out the parts you don't need and add weight where needed to compensate the imbalance in the mechanical system.Like for example having the most "shielding" metal between bar and drum when the binding forces would be max.Hence the need for correct distance to prevent unwanted binding forces from the drum parts ;)You can even influence the width of your magnetic bar to some extend this way ;)If done properly you now wasted a few weeks in your shed and have a motor that still is only very close to keep running forever once you gave it a little push.Let's say you did a really bad job.Means you still have one or more destinct binding points left.In this case I suggest you focus on them after finding out if they are mechanical or magnetic in origin.If you did a half decent job then your machine should be able to start running from multiple points in the rotation.But not in some others.Perfect would be two equally sized areas per revolution where it seems the thing would just need to be started a few degrees later to overcome the power loss.If you reached the max point and going a few degrees more again start to reduce the power output you are good to go.What exactly haapend so far, assuming all is still well in your shed?We tricked our system in various ways to actually utilise the push/pull forces our motor provides.And we learned what to do and how to do it so we overvome almost everything.Just to finally fail like all those idiots on the net before - or did we??? ;)Isn't there something really vital we missed in our construction while we cheated so much?There is but I can't blame you if you have not picked it up much earlier in your construction.We rotate our magnet bar now to compensate for the binding effect by mecahnical means.Ever wondered if we could more rotation and changing orientations in our V?The magnets won't mind too much if they are put in with north and south alternating as long as you rotate the bar correspondingly.Just instead of one spin or flip during max binding you do it for every single magnet in the row.... ;)The shielding drum though operates as normal with this.Bit complicated, lots of mechanical design involved - I know!!!And for what exactly???To use what have not even touched yet - electrical energy produced by our now alternating drum ;)I know :( Now you are whacking your head against the wall like I did so many years ago, sorry for that experience!But would it mean that coils will cause additional losses and binding forces?Of course it does, that's why it is so much fun trying to cheat physics!This approach is usually just neglected due to the ill thinking that a magnet motor would provide free energy for everyone.Simple fact is that no matter how good you are it will be impossible to get more than a magnetic machine that almost works forever - you won't be able to compensate for all losses and utilise them as energy unless you either have multiple high degrees or spend a lot of time in your shed - a lot...Since a full rebuild is now due anyway I leave it up to you to figure out how desgin it, I just throw in some "ideas" here:We only use the outside of our magnetic drum, this needs to change.And before you go into a mechanical frency to figure how to place inner magnets that rotate with the drum to compensate for dead zones: Just don't! You will get a headache and waste too much time.We can use all those inwards facing magnets to our advantage though.A lot of the arrays, if not all, could be replaced by creating a rotor to hold the magnets.Not in the traditional sense though but to guide the field lines to a common center.There is a need for a rather wide distance between the magnets so you can provide a ferrous pathway that won't just fully shortcut the fields.It needs to be enough so that a coil array placed on the inside will be subjected to changing fields- north south...I leave it up to to decide if a low resistance or ahigher output voltage is the better option.Either way we are able to produce some electrical energy as long as the drum rotates.But we only need extra energy for those ares where the system does not produce extra energy and in fact eats all our energy up.One way would be to store the electrical energy in a nice supercapacitor and to use it for some electromagnet that is placed in the right spot and activates at the right time.And yes it works.Far better though is to utilise resonance.We aim for a fully harmonic system so we can actually try to figure out where and if there is a way to produce more neergy that what we feed into it.Perpetual motion means a system produces enough energy to sustain motion.If motion is sustained AFTER getting to a certain speed by other means it is perpetual from then on.We have the impossible if a machine produces more energy than what is required for the motion AND if we can utilise this power.Sadly we have no means to utilise friction energy....So a machine that sustains motion would already be in what is called "over unity" !?In a sense yes, but not in a usable as it will discredit you quickly.A resonant electrical system is able to handle way more energy with way less resistance - or losses.Now to give you the final homework lesson and risk being watched again:What do you think happens if a resonant LC system has a set of rotating magnets at a matching speed? ;)Right! It won't be able to stay in sync because we still have this firction and "binding" problem on our hands.....What does that mean in reality though?The spacing of the rotor is critical, that is clear already,And our electrical system is never fully in sync with our drum, clear again.But it is still a resonant system, totally unclear, now I lost you ;)See it as two independent frequencies, one defined by rotor spacing and our desired operational speed, the other what results from our losses and running slightly behind.Imagine you would finetune the LC system to actually match the frequency that results from the losses....Suddenly it is not longer tuned to a theoretical speed but to the real speed.And due the the now full resonace the phase shift now is able to provide extra push for our system ;)Explains nicely why basically all magnet motor machines that claimed to work and disappeared only worked at a fixed speed ;)What are the final conclusions here then - is it really possible to do the impossible?I say it depends on your time, workshop and willingness to think out of the box.Impossible, certainly not.In case you came to the same impossible conclusion after neglecting your family and friends for weeks you now wonder how much more might be possible than just keeping it going for almost forever.For this you need to understand and basically feel how magnetic field lines interact and react, including electromagnetic fields.A magnetic field is a form of energy.We usually created this by putting an awful lot of energy into coild during the manufacturing process.And like a battery magnets lose their energy over the time, especially in bad conditions.Still we treat this energy as unusable because we can't seen to be able to utilise static fields at all.If neither the coil, nor the magnet moves there is no change in field and with that no electricity.Does that mean though the megnetic energy does not go through the coil? ;)Nope, it is still there, going nowhere.Otherwise we would not need power plants and just use earth's magnetic field instead.Now to drive your brain into true overdrive for the final:Did you ever watch these nice videos where a great physics teacher of the old kind shows how (AC) electromagnetic field work?Or maybe you had one of those in school?Remember how a metal cylinder placed ner a tall electromagnet starts spinning?Often used to explain the righthand rule ;)The cylinder spins due to the eddy currents created - like the disk did in your old school electrical meter in the fuse box.And doesn't our drum now support a changing magnetic field on the inside while it rotates?What do you think happens to "drums" placed off center and close to those magnets? You think they would spin?And, if made from aluminium or copper, wouldn't the field lines stillpass through and reach the electrical coil(s) ;)Couldn't you utilise the drum motion during the times of not enough spin? ;)Considering they are basically short cut inductors: Couldn't you use a "coil" that still spins while producing electricity? ;)Once you can answer this with confidence you will know how to build a magnet motor able to produce excess energy.I am not saying it is easy to include all this knowledge into a simple and basic design.But I do say that one you understand the relation between static permanent magnetic fields and electromagnetic ones you are a winner.I'll give you one final hint:Every electrical current or electromagnetic field near enough to a permanent magnet will influence its field!You only need to decide where the electrical energy is used to influence permanent magnets is a positive way without using more than what the system is able to provide.Then, and only then, will you motor to be able to start (with no load) from any position and keep gaining speed until resonance is reached.The amount of energy you can draw once this speed is reached is only defined by how much it drives the system out of resonance.Once the load is greater than what the system can sustain the speed slows, resonance is lost, efficiency down the drain.A good motor of desktop size is able to provide about 100W of extra electrical energy.And no it still isn't over unity or perpetual at all!The magnets deplete and they do it surprisingly fast in a working magnet motor.You are lucky get 6 months of continious use before one or more magnets get too weak.And if you check how much electrical energy was used to give these magnets their abilities you realise that even two years of usage wouldn't make up for it.Still nice to have a machine that runs for a few years with no load attached or that powers some fan, lamp, whatever for a few weeks without batteries or fuel.

Facebook and privacy in VR - on a worse level than for the social media app...

These days not just isolation drives more and more people to try VR - virtual reality.It is great fun to watch a movie on a huge screen you have on your head and even more fun to actually play games while moving around and dodging bulltes.But when it comes to the famous Oculus headsets we might have to pay a hefty price - several times....Imagine you just forked out the $400 or so bucks for their latest headset and want to get going....It is a standalone device, so how hard can it be?....Pop it on the head, turn it on and follow the instructions that shall come.Well, before you can do this you find a piece of carboard covering your lenses and if you bother to read it you are getting slightly confused - if you are privacy concious person like me.I can set up basically any Android device I like without the need to have another mobile device or computer to do so....Not with Oculus, or to be precise Facebook as the actual company owning Oculus.You first need the Oculus app - appearently because it makes the setup process soooo much easier.How does this two stage initialisation actually work and what are (with FB always) possible privacy concerns?For totally unknown reasons Oculus insist that you need location services to turn on a VR headset for the first time....Without this you won't be able to proceed.Means in reality FB gets your pinpoint home location provided, whether you want them to know or not, whether you have a FB account or not.They also need a "real" Email address.Most freemailers are rejected here, claiming they would not allow for a verification.Disposable Email providers are rejected right away.Depending on your operating system clicking on the confirmation link in your Email will then also provide vital data on the OS, device and Email client you used, and of course the browser.So far so good, or bad...With your Oculus account finally ready you can proceed and try to link your headset to your mobile device to complete the setup.Isn't it great that you can type in your Wifi password on the phone instead of using the headset?Not claiming FB does but it would be dead simply to collect that info from you as and to send it home...Unlike Google Oculusis still unaffected from authorities getting concerned about data hoarding, tracking and privacy exposure.No wonder than that your only option is to agree to all terms and conditions - for everything FB deems fit.If you actually bother to read these terms and conditions two things become clear quickly.1. You basically have to give your identiy to FB unless you cheat properly right from the start and from well before trying to pair your new gadget.2. All concerning privacy and information sharing options will be turned ON BY DEFAULT. It is quite a long process for a new user trying to find the few things you can turn off...After all this you can put the headset on and try to explore - well, not so fast please...There isn't much free content in terms of games or good experiences, so you need a payment option - a verified one....At least this option is not forced on you right away and you CAN continue without setting up a payment option.For now anyway....You are finally there, you made it and can enjoy a 3D environment for the first time!A bit of fun and help from the UI to get you going and it is time to do things...No full game of any use comes installed, so it is the first thing most new users want to try.Not much free games at all, a few Demo games, previews and the rest...Well, let's say IMHO not worth wasting time on unless you are below 13 years of age and like simple shapes.You decide on some Youtube or some of the great 360° experiences on offer and might actually waste your first charge on them.While the thing recharges you start to wonder what else you could do....You have some nice movies in your DVD collection, wouldn't it be great to watch them on the big screen?Let's just say it is quite a hassle to get a real DVD to appear on your headset and play.But things like Netflix are a breeze to set up if you already have an account.For your normal Android, PC, Laptop or MAC you find a huge amount of really good and really free video players.The VR community though is locked out thanks to the content control in the store.Most things start out "free", like Skybox once did so the users can sort out bugs, help to create something users want and value.Then the support ends and there is only a paid version available.Unlike your other devices you won't be able to use the old, free version any more, it just refuses to work.Same for all the demo and preview games, once you start to like it, it is over already.Then you need to pay to keep playing the "real" thing.Frustration sets in as you did nt really buy a 3D headset just to watch some movies and do software testing.You need to buy something to make real use out of the headset.Great thing is that you get a 14 day full refund policy - read it carefully!You basically have about one charge of the batteries to try something new you paid for.Use it for two hours and it is yours forever...Even if you wife called for dinner and you just take the headset off and trust it goes in standby.It does, but unless you used the exit button the time for your new purchase will keep running while you eat.Yes, even a blank screen is standby then counts as time you used the app or game ;)You could accept all this, considering it all new to you and just need to keep an eye or better alarm on the 2 hour mark.Oculus does not like it though if you "test" a lot of things only to ask for a refund.Try 10 or so titles on a long weekend and ask for a refund, then check the response you get for the next weekend of unseccfull testing...For many titles and apps the price is IMHO outrageous!Even things that have been free or dirt cheap for often decades are now sold at a premium.Fruit Ninja, Tetris for the price of a good steak....A $50 "Game" is played through in often less than 2 hours, after that it is the same again and again, you only get more points but won't see anything new.And then there is is this addon or parts thing....You get a free game or experience only to find that most of what you are after is available at additional costs.It is very, very easy to quickly have a collection of a few apps and games that are worth more than the entire VR set....It is a scam...There are not many apps or games to begin with and even less you could label "exclusive".Especially for the Quest and GO Oculus uses ported games and apps - often those who were available for years on their higher end platforms.Often with higher prices than anyone could understand.A port costs you next to nothing, it a more or less automated process....Many things are available with a license of sorts.Steam for example makes it quie easy to use a game you pruchased on multile platforms without ripping you off in the process.You could buy 5 Oculus VR headsets for your family to enjoy lockdown in the virtual world together...Maybe a Quest each for the parents and then some GO's for the kids?Sadly Oculus does not provide anything for owners of multiple devices, unless you mean using a high end PC to stream Steam titles and hope the thing won't start smoking.You would think that if you bought a bunch of devices for the family that you could enjoy things together with ease.Well, every app or game you need will need to paid for every single device at full price...Suddenly watching you movie collection with the family sets you back well over 100 bucks just so that everyone has a player for the movies installed.Doing some family battles in a VR game can set you back $250 with ease!Suddenly a virtual family gets really expensive, really quickly...One of the reasons you find so many second hand devices that were only in use for about a month or two until the owners gave up on VR....Let's sum up what FB does to make a lot of money and collect a potential mountain of information on you in the virtual world:You provide the follwoing freely only to get the thing running:You name and full address - the later confirmed by your GPS location.Any location you use the companion app and pair with your headset, so your firends places as you need to set up a new WiFi connection...Your personal Email address and postal address unless you bought over the counter and decided not to register your device for warranty purpose - and who would need warranty for a device only worth a few hundred bucks.... ;)To really get going you also provide the following:Your credit card details.Accepting that there is no real security to prevent your kids installing what they like in paid apps once a credit card is linked.It is possible but again not really easy and straight forward to set up.Your social media accounts - FB already has you FB account if you used the same Email Address anyway without you making it offcial on your headset.Now, I don't know about you but should I really trust a company like FB would to only the right thing with these informations?? History showed us how much we can trust FB on privacy...Any further hassles?Well, if you do have a lot on you laptop, PC or just phone you do backups, at least you should.Oculus does not really provide such an option.So once you storage space runs out, and it can do so quickly especially on the 64GB models, you need to delete things.Appearently once you bought a title it is your to keep and you could, in theory, just download and install it again - once you deleted other stuff....You can't even connect to any cloud services or network storage you have for this.You need to constantly charge or use a cable with a battery pack/charger.I could not finish a 2.5 hour 3D movie on a single charge....What about community projects?Be it Playstation, Nintendo or just plain Android, you find thriving communities that provide a lot of additional content and usage options.Homebrew is great for everyone.Especially the GO and Quest models are basically nothing more than a stripped down Android phone with a split screen.Means Android or Android TV apps that can cope without any Google services and frameworks will work just fine.FB does not like this much so and makes it very hard to utilise what you might simply call emulators.Unless the Android(TV) app supports the gesture and controller setup Oculus provides many things just won't work as you need them, for example pinching to zoom in and out or tapping on the screen if the app expect a real touchscreen.An emulator would basically convert what is available in gesture and controller actions into what a "normal" app or game would expect.Some game controllers are supported but would it be great to move around for real while exploring your 3D game and to use your own hand to perform actions istead of holding an additional game controller?Oculus does not support "Thrid Party or homebrew", depending on how you read their agreements you accepted, it means your account might be banned, rendering your expensive device useless for any offcial stuff.There are unofficial, or if you like homebrew stores available.A place where you find early stages of new titles to try out, some free content and also experimental stuff.At your own risk and frustration though ;)A great project that never made it due to the complications with Oculus/FB was a robotics VR app.The goal was to control a robot or even mobile one, like a rover, through the headset and controllers/hands.The project ended when it was clear FB would not provide the required API stuff unless the app is devleoped under Oculus terms and conditions.Needless to say it quickly continued on a higher level for military use and remote bomb disposal.Some othe, private company saw the actual potetial in homebrew and snatched the developer off.Can't blame the guy considering the money...The main concern for any serious "hacker" providing real homebrew solutions are the offcial terms and conditions.Google for example still works o your Android phone if you install some custom firmware.You can even keep using the Samsung store and Apps if you did install homebrew on such a phone.Not to mention that you also install basically any other unofficial store you like on top.What you ultimately do with your device is up to you and might only affect your warranty based on claims that not always make sense.Oculus however reserves the right to terminate all access to their online features.This can include but might not be limited to:Updates, online store access, online features provided by Oculus and online features provided by apps and games from the official store.The concern here is that it basically means not a single Oculus app keeps working as they all call home once online.Games requiring Oculus services, like purchasing the next part of the experience fail then as well.And if played hard it means your linked account means even you favourite video player will fail to work.So far Oculus only made it hard and then even harder to give homebrew or alternative uses a chance.Not too many developers want to be responsible if their testers or users get banned and their devices rendered basically useless.What about predators?Vr is still a new thing in most parts of the world, some are already hooked in great numbers though.Especially in Asia Vr seems to be the new future already.Hackers showed in the past how easy it is to enter a room on a Oculus device and stay invisible, listen to conversations and even access the camera feed and take control of linked computers.Good hackers though who did this for the right reasons and results - those backdoors were closed.But it shows nothing is perfect, especially if age and content control is left to the user alone.VR works best with friends and if you don't have any (with a headset) you quickly find them with your heaset active.Many titles are "kid friendly" so to say and still offer chat options and virtual contact.No kid can buy these toys, so the responsibilty is entirely placed on the adults providing the technology to the kid(s) - usually the parent or unsuspecting family member thinking a VR headset is great xmas present for the teen..."Groomers" not only know what to say and when, they also know quickly if the watch a kid play and once they had a few minutes of chat they get ready.I have small kids in the family and with lockdown we are often reduced to doing things online instead.If you enter one of these virtual worlds and appear and act like a kid you soon find "new friends" especially if you pretend to by shy and prefer to be left alone.In the real world you won't find any kids bothering to become your friend if you act like this.The virtual world however seems to have an endless supply of kids like you and desperate to find a friend thinking and suffering the same....We all know how many of these kids are real on normal social media platforms and how reluctant they are to let the parents check on each other to allow these "play dates"....You might be able to monitor and moderate a written chat platform, no so much though if everyone is talking for real....A growing concer here is the nice option these VR chatplatforms offer to create "private" rooms.Be it for just chats and playing with wirtual Lego or to share a nice movie, there is an option for everyone.Parents usually don't bother to set up a screen for monitoring of what happens on their kids VR system, maybe they should...They don't see what the kid does and since it can get annoying, headphones are prefered, close the door and no one hears what the kids talks, if anyone cares.There are already pages on the dark web with all the required instructions to set up "a most pleasurable" VR experience - you just read them down so even a 6 year old can install and set up what is required - again use the few parental guidance options available on these headsets.So far the real risk is limited by the simple fact that not every sexual predator uses VR and that not too many kids (yet) have access to headsets.Does not mean there isn't planty of options to use their phone and some "CARDBOARD" to get going without a headset.There does not seem any concern to protect underaged kids in the virtual world - let their parents do it...Keep that in mind when handing over a VR headset for kids to use unsupervised for long periods of time...

Magnetmotor - really impossible or just supressed?

When someone starts talking about a so called magnetmotor than most people judge right away.Laws of physics, perpetuum mobile is impossible, magnets are static....We all know the limitations nature puts on us... That however did not stop quite a few people since the 1950's to build working magnet motors. Or, to be precise: To make the claim, show them and then somehow disappear. A few though seem to have survived and even claim to make good business. Securely closed machine, stellite tracking and 24/7 online monitoring. Either just a bad and long running hoax or a real attempt to keep a secret secret. Even the somewhat famous Yildiz motor showed off around the world only to disappear.Some like them, some don't. Either way all this sounds like the perfect conspirary theory LOL So lets take a look on what is fake and what might be real but missing some vital clues. You can find several good Youtube channels created by people trying to build a working magnet motor. Some of them have no problems to admit failure and still keep trying and updating their projects. Did long enough and you see two outcomes. The first is giving up or "realising" that it will never work. The second often seems like a user is getting some relly good results and is really close to keep the magnetmotor running. Both disappear without and updates or traces. Now of course this is just confirmation that it will never work, but then again: What if it did already quite a few times? Even Tesla had patents for a magnetmotor and so far none of his patents were a hoax. Although none of his patents allow to actually build a working devices without some additional info and knowledge. And that is the key that I am trying to get: The lost knowledge.How can a magnetmotor never work? That one is quite simple from the start. If a linear model won't work no matter where you start then a rotary version will fail as well. And if a linear version works, it has to do so far at least 5 segments and with preferably increasing or at least constant speed. Having said that and assuming you know a little bit about magnetism: Ever wondered about shapes of magnets?? The common types are block, round like a bar and those disk like ones, some even with holes. A less well known version is the ring magnet. You can look them up as well as their corresponding magnetic field geometry - or what is assumed to be the right geometry. To give you a clue: All those floating spinning toys use a ring magnet in the base and onother one in the spinner. In the center is a dead zone for the magnetic field that is far lower than further out on the ring. And the strnger outer fields also reach further - giving the entire spinner a bowl like area to float on, the spinning just stabilises it like a gyroscope. A similar flat disk magnet wouldn't have this indentation in the field but rather a dome like sphere. The ring just kicks a dint into this sphere if you don't mind the simpification. Similar changes in the field structure happen when you combine two or more magnets. One example we all know is stacking identical smaller magnets. And often we are suprised how much stronger two thin disk magnets are compared to a single. Distance however sets a certain limit. And take those hook magnets... Just a small ring magnet in a metal pot with core. Remove the magnet and just by itself it is far weaker. Why? Quite simple.... The same way a transformer core directs the magnetic flow, the metal part of the hook magnet provides a shortcut for the magnetic field - and in return all is much stronger ;) Now you have some more clues, but still there are tons of options for failure... The most common is the sticking effect. No matter how well you planned and designed in most cases you linear or rotary prototype will stall sooner or later. Even if started manually at high speeds some seem to run very long but once they slow down and stop it is obvious they always stop where the magnetic field won't allow the binding effect to be overcome.Wouldn't dare to say that I have a working magnetmotor, but I might have some clues you want to try if you decide to give it a try yourself. So how COULD a magnetmotor actually work? Like in the Perendiv examples all over the web, you could aloow a moving responder to the rotor. Like a piston the responder will be lifted in areas it would otherwise limit or reduce the speed of the system. Well designed only a few mm would b required but it also means wasted energy to move the responder. Then there is the nice way of modifying fields by adding magnets in different angles and polarities. Lets say towards the end of your stages on the linear model it is hard to overcome the binding effect from the end of the previous stage. The perendiv model would now somehow change the distances. But you can also add magnets to lower the binding effect ;) Like a ring or hook magnet you can shape the field and offer a stronger repulsin field or a lower binding force. Last but certainly not least is the option of adding magnetic metals like iron or somehow weirder ones like bismuth. So, do we have any examples of something very common utilising any of this? We sure do :) Take a speaker apart and you end with the cage, the membrane, the actual work coil and the magnet. We don't need anything but the magnet so take a good and very close look. What in the audio world is called a shield to prevent the magnet from messing with things close by is exactly the same as on a hook magnet ;) Only difference is the tiny gap for the coil. The magnetic field is directed into two paths, one by the metal core, the other by the inner enclosure of the magnet or the magnet itself. The coil operates in the area of maximum flux.Last hints... If you take two identical and strong magnets with north or south facing up then it is quite hard to push them very close together. But check what happens if you try the same wen both soth poles (or both north poles) are placed on a magnetic surface - if in doubt your standard fridge door. Suddenly you can move much closer together with the same amout of force (not considering the added friction!). And similar story for opposing configurations. Where in free air or on a table the magnets would just jump together, on a metal plated you can move them much, much closer before this happens. Copper pipe and magnet fun :) Ideally you would have a straight copper pipe and a cylindrical magnet that has a loose fit in the pipe. Aluminium pipe work too or even a roll of aluminium foil if you have nothing else. A magnet in the pipe will travel very slow down the pipe, friction is not an issue here. So what is slowing it down? The magnet creates a field in the pipe and through that the pipe generates electicity. And funny enough this electricity creates an opposing magnetic field in the pipe - the magnet slows down. Even if you glue it onto a wooden stick it won't rush through it. Trying to push it by hand and you feel the created resistance. The faster you push, the harder it is to push! If you made it all the way down here with the reading then I have to assume you fit into one of three of my categories. a) You are a total sceptic and just read it for your amusement. If so, then please don't post a reply with usual negative feedback, instead see it as the same fun you had reading it ;) b) You are at least curious and like to play with magnets. In this case take the above as inspiration to explore more ways to have fun with your magnets! c) You are more or less frustated because you wasted a lot of time and some money to build a magnet motor that just won't work. A and B might go on and enjoy the fun, C however might want to read very attentive now ;) If you take some indicator sheet for magnetic fields, like these funny green ones, and play with moving magnets then you see a very interesting effect on the "screen". The otherwise static field lines change chape and sometimes even seem to disappear or shrink. With a small rotor assembly it almost looks like flashes when the magnets move past each other. This effect is often totally neglected and to be honest I overlooked it for a long time as well. Being able to see how the magnetic field changes gives the thing an whole new dimension so to speak. Creating a magnet with a complex shape is difficult to say the least. Only ferrite or ceramic ones can be used and you would cut of machine them according to your desired shape and with regards to the orginal center of the magnetic field. So most people revert to the classic way of shaping by adding magnets of various types, sizes and amounts. Modern neodymium magnets make this trial and error process easier as there are many sizes and strengths available. Add a detector shield of suitable size and you have hours of fun time ahead of you. But doing so in any rotary assembly is next to impossible. So what did Yildiz differently and what was missed so many times? Yildiz took it a step further and not only provided "shunts" to create very strong magnetic field from the generated electricity but also a second rotor. Since we all start small lets focus on the basics first. Remember the hook magnet and speaker or the copper pipe? Some examples for shape shifting your otherwise static magnetic fields: 1. A magnetic metal "connection" from one (low in the armature) pole to an opposing (high in the amature) pole with cause the field from the "high" pole to "bend" towards the connected magnet. 2. A magnet with an orientation of 90° to the last magnet is the sequence will severely influence the field of this last magnet! This goes for either orientations! 3. Adding a non-magnetic "shield" around a magnet, like a piece of copper pipe, will not affect the static field of the magnet. However it will severely alter the field of the enclosed magnet when another magnet passes it! It will also affect the overal field during the passing as the moving magnet will also induce a field in the copper by affecting the field of the enclosed magnet! Thickness and lenght of the shield influence the strength of these effects. 4. In a simple perendiv motor design the bar that creates the attraction for the spinning part is a magnet too. Either a long bar type or two small ones with an iron or nickel rod between them. There is no need for a piston or something that drives the bar up or out of the way ;) Just use the right magnet at the right spot on your rotor to repell the bar ;) Mount the ar with suitable springs and you suddenly can have multiple stages on your rotor instead of just the usual one! Don't forget the moving magnet on the opposing side of the segment in question though as otherwise you still will get stuck. (Hint: You can place a small but powerful magnet in the center of the opposing bar ;) Just make sure you limit the springs movement so the bar won't be pulled closer)Ok, hold on now! Does a magnet motor actually work or not? I can only give hints and say the laws of physics as we know them apply to magnetmotors the same way as everything else. Unlimeted motion without supplying energy is not possible. Limited motion with adding or using energy however is still possible and real. The same is true for being able to machine, 3D print or otherwise manufacture at very tight tolerence and accuracy levels. This includes bearings or bearing systems with very little friction losses. Just check these floting and rotating magnet toys that look like a spindle. Only a tiny needle like pin makes contact with a glass surface - next to no friction loss. A proper and supposedly working magnet motor should provide more energy than what it uses - one way or the other. No law of physics lets us get around the fact that such a motor could only keep spinning if the produced power or motion energy is at least the same as what is required to make it move. Magnets lose their strenght over time, they are like a very slowly depleting battery. So, isn't it funny that all magnet motors so far that claimed to work also had the requirement to replace the magnets once the things fails to work or start? And if you leave a very strong neodymium magnet shielded from outside fields or magnetic stuff than your grandkids will still find a quite strong magnet. Do a little performance test with your new magnets, like how much force is required is required to lift them off a steel plate. Make the same test with the magnets once you played around extensively with them in your motor. Now take a spare magnet that was never used from the orginal batch and compare both against each other ;) If the motor would not use energy then why are the magnets depleted to a certain degree, realted to runtime and usage time? Wait a minute! Does that now mean it actually works? Lets just say energy is certainly used. We only know similar effects from electromagnetic systems. But did anyone ever really check how much actual energy is in magnetic field generated by a non electric magnet? Get a good sized N52 neodymium magnet and check how much force is required to pull it off a steel surface. Now try to get the smallest sized electromagnet capable of that force and check how much energy it consumes at the level that equals the pulling force of the N52 magnet ;) Makes no sense to even try to compare these you will say now. I just say energy is energy and we were formed to only think in certain ways and don't even try silly things like this ;) To keep the fun up let us imagine we would actually have a similar energy available than what our electro magnet would require. In reality more because we wouldn't have electrical or flux related losses in the metal around the coil. Or is the imagined reality, no clue ;) If true it would mean even a motor with very bad efficiency would be able to create huge amounts of torque. Well, torque is basically acceleration. Which would mean our motor would not just be happy to spin, it would speed up until the bearing fail or the thing is ripped apart. Imagine a dental drill of that size and weight suddenly falling apart at full speed... Every example of motors claimed to be working, that are not fakes, seem to be happy no matter what the load is. It the thing turns a generator than it would have to slow down a bit with the increased load but they don't. With no limited factors otherwise this makes them a fake. Even a perfect motor would have to react to load changes.... Don't we agree that the stronger the magnetic force or field in a conductor the stronger the resulting magnetic and opposing field of the conductor? We use the difference to either drive a motor or take out electricity... But if you take the "open" shielding of a magnet in a changing field than the influence of the shield on the overall field gets stronger with stronger field changes. And properly desinged and orientated they would actually double as a natural limiter for the rotation speed. Once the electrical energy in the shield becomes too strong it will be able to cancel out the field of the enclosed magnet...If we assume a magnet motor is really possible and works with the intended output to keep it spinning or even take energy out: Then what would be possible downfalls that stop this thing happening in everyones garage? We can explore the stars but so far no one bothered to invent anything to visualise magnetic field in a 3 dimensional way other than by simulation. No realtime and true observation like this. The few working technologies that exist rely on sensors, interpretaion and filling in gaps. But imagine something like a detector shield as cloud! And then even better with selctive spacing to get a realtime view of where exactly the field lines go. All we can do is forget our teaching and try it out anyway ;) If by some mistake a magnet motor would really work right away, then chances are high the inventor would wonder why that thing takes off like mad and how to stop it. Unless well prepared it would certainly end in the destrution of the motor. But the inventor would know what to look for in the next prototype. The logical conclusion would be to the couple the energy taken to the speed while physically limittin the free load speed. The other one would be the design the electrical generator around the and within the motor. To even get close to this point you would have to spend endless days and nights working on finding a solution. The closer you get the more disappointment when the final model still fails to keep spinning for more than a few hours. Most people will then accept defeat and move on... Still not saying it actually works but if you made it to this point in time where it could be easier to move on and do other things:Ever wondered what would happen if you "shield" a magnet with a coil? Of course nothing would happen as we know. But try this in some fixed assembly that allows you move another magnet through the field of the shielded one. Perferably witha force gauge or some option to read out the energy required to move it through the various stages of the field. See what happens if you short the coil or add a resistor to it ;) Now if this coild is able to produce electricity then the more we use the more the effects on the required force would change. What do you think would happen if you combine common coil relations of electric motors to a "coil shielded" magnet motor? Right, all these coils would interact with the magnetic fields of the coils they are connected to... And through that with the overall field surrounding the enclosed magnet..... I leave up to you to imagine how these interacting coils could provide "resistance" or "acceleration"/"surplus electricity"...Like they say: You can only find out if you try ;) To keep up the positive thinking: A permanent magnet just sticks to any magnetic surface and does so with the same force. But the real energy loss in terms of getting weaker can almost be neglected. Any electromagnet capable of the same holding force woul require ongoing energy supplies to keep it up. It is using energy the same way the permanent magnet does! The difference is the permanent magnet is not seen as anything that would provide us with energy.... And if it can't provide energy other than passing through coils then why the heck does it keep sticking to the fridge year after year? It does require energy to keep this weight up doesn't it, even if you add a thin teflon disk and oil to reduce friction? ;) No magic, no "free energy" bogus, just plain physics viewed from a slightly different angle than what we learn in school ;) Have a good laugh and a good beer, then read it again and just consider some of the things here that are not mentioned in any literature about magnetism that we commonly use. Now I got you thinking, didn't I ? ;)
