I'm back.

I left because I was annoying people too much, and I got a PM from a mod telling me he 'expects better behaviour in future'. I kept meaning to get back to it, but I just got caught up in a lot of stuff which was happening. Its christmas day today, weird, because I'm currently in England. When I did get time to go on, I decided to play BF2:BC, TF2, Minecraft, HaloCE or Mercs2. Well thats pretty much it. I'm back.

Delorean Time Machine

Hi guys, I would just like to ask for some tips/advice/suggestions on how to build a Delorean Time Machine (as featured in Back To The Future). I'm not talking about an actual scale model - decent ornament size will do, to be displayed on a shelf. It would be cool to include some fancy electronics inside of it. Perhaps a digital alarm clock?

BMW from back to the future remake!

Well, i was a massive fan of back to the future, and i found this great remake of one of the 'futuristic' cars from the second film.I think its great how films take newly released cars, stick some junk on them, and make them look like there from the future, they still do it today!'Chabotte restored the car to movie condition - obviously, and sadly, without flight capabilities.''Chabotte spent his blood, sweat and tears on this project strictly for the love of the car.'Hit the link for the full story, and a great gallery!viaJalopnik

Real-life Back to the Future 2 hoverboard

French artist Nils Guadagnin has built his very own hoverboard based on the hoverboards in Back to the Future II. It's pink, it's a board, and it actually does hover when placed on its platform. Integrated into the board and the plinth is an electromagnetic system which levitates the board. A laser system stabilises the object in the air. The board is hovering with the help of two CLM-1+ levitation modules made by Crealev. Hoverboard Project via geekologie

Back to the Future Part II Nike Shoes

Sup, everyone! So the idea I had was the nike shoes in back to the future part II. I got to thinking that it would be really cool if i could make a pair, so i looked around and found that nike had already made a pair back in 2011, it looked to me like they used reinforced foam. So then the next thought i had was get on instructables and get some ideas from you guys. The basic idea I have is to modole them out of strong foam, i'll probably make a cardboard mockup first, then line it with fome and material. after that I'll probably get some really stiff foam then make the outside out of that an probably make the sole out of rubber. Please share your ideas, thanks in advance

Back to the Future contest opened a bit late

So, as we all know, the day that Marty McFly travels to in 2015 is fast approaching (October 21). As a big BTTF fan, I put together an entire Marty McFly costume complete with holographic hat, Nike Air Mags, and jacket. A couple of days ago I posted an Instructable on how to make the jacket, but now it seems I am ineligible to enter the Back to the Future contest that just opened today. (I didn't even know about it because it wasn't on the upcoming contests forum post or the contest page of the app) Obviously, I'm pretty bummed and honestly it seems kind of late for the contest to start only two weeks from the day that people are going to want to have a bunch of BTTF props and costume pieces put together, don't you think? I actually rushed to get my tutorial finished because I wanted to be sure that others in the community would have enough time to follow it and make their own. Anyway, I was just wondering if anyone had any suggestions on a way I could still enter. I would just post a new, improved Instructable for the same thing, but I don't want to feel like I'm spamming or have my featured percentage to go down. =\

The future of K'nex guns?

What is the future of K'nex guns? It had literally been almost a year since I had been on this site, and when I came back, I was almost shocked to see that the best guns a year ago are still the best guns today.  There has been almost no improvements or innovations in the past year, and in many cases, the guns have gotten worse.   I really don't want to sound mean but this is a problem.  The only ones that I have seen (and I haven't looked around too thoroughly yet, so correct me if I am wrong) that have created something notably innovative and new are TheDunkis (new ram concept and gun), Zak (swagboss), Knexguy (bullpup bolt action), and Jollex (repeating sling).  And of course there are a few promising new-comers such as Icetank and Ryry.   I just want to encourage you all to at least try to think of something, put it down on paper, let others know, and even try to build it.  And even if there isn't something completely new you can come up with there are still so many things out there that need to be perfected such as pump actions, shotguns, repeating slings, horizontal (tube) mags, etc.  You can even try to combine some for an even more impressive gun. Personally, I think the future of knex guns are in horizontal magazines, as they are very rarely used and there are so many unexplored uses they can be put to.   Hopefully that inspired you to try something new, and if you don't agree with my point of view, prove me wrong!  Show me something that you've made that will amaze us.  I am simply trying to inspire a new year of knex guns.   So, what do you think the future of knex guns is?

The future of "mobile" energy...

Right now our current standard is still to use LI-Ion batteries when it comes to rechargable and power demanding devices.We all want more power for our phones, laptops or battery powered tools on the job.And we also want to be able to charge our batteries faster and faster.Back in the old days a D-Cell like lead acid battery in a flashlight was good for about 3 hours until it started to dim a bit.With up to 4 batteries inside they were not just heavy but also quite hazardous.Chargin was usually done over night and you just hoped they were not blowing up while charging.I spare you the other types that came after and that we still use as they all have their good and their bad sides.If we trust our marketing experts than quite soon we will only have electric cars on our roads and battery the size of a suitcase shall be able to run your car for hundreds of miles.The ideas of graphite based batteries or those using crystals and their forming reactions are all great and promising.Some will certainly make it to the consumer in a few years.The one thing that we are never told though is where all the energy to charge those batteries is supposed to come from.Replacing the combustion engine with electric motors is one thing but if no fossil fuel is used....Energy does not come out of thin air!Right now a lot of countries already struggle to provide a reliable power supply grid and distribution network.If you ever enjoyed a scorching hot day during a blackout caused by everyone using too much electricity you know what I mean...The population is growing as fast as the energy demand for our industries.Solar and wind are well and good but without proper storage solutions of not real use because no one can really predict how much they can produce.You know, weather and such things...If we trust our so called experts than all will come together really nice.By the time we have really powerful batteries we will have enough alternative energy supply chains up and running to keep them charged.I have a few issues with this entire concept, so let's see what other people have to about this:Imagine you have a nice and big cabin somewhere really remote and beautiful - but with no electricity for miles.Obvious solution for the modern hunter or nature lover is to invest into free energy.Free because that is how your solar, battery and inverter system would be advertised.You buy the stuff and after that all the electricity comes for free - the things pays for itself!Reality is a bit off though as you need to maintain and replace the costly batteries over time and such things.All this however totally changes for a residential home.Getting a huge solar system on your roof is no problem.Getting off the grid next to impossible.You see, once (or even before) you sign up for an electricity contract it is defined that your home is in a residential area.This brings certain limitations like the requirement to connect ot gas (if available), water, sewage and electricity.Only way to enjoy your "free" energy is by getting a good deal with your supplier.Some countries do it differently but around here it goes like this:Whatever you use still comes right off the grid.That is because your solar system really struggles to cope with load changes and providing surplus back to the grid.And since your meter is not capable ofworking properly with it either...To make it "fair" it is metered how much you use and how much you supply.Most companies here even do this on at least an hourly base - just to fair...For your bill the amounts are then adjusted.What you supplied is taken off.Sadly in most cases going negativ is not an option - if you provide more than what you use only your supplier is laughing.To make things worse what you supply is valued far lower than what you get from the grid.Often the difference is above 20%.Control....Around here quite a few people basically covered house, shed, carport and all with solar panels.This was while we had a great subsidy from the government to go solar...After now over three years most of these people still struggle to get anywhere near even for their investment.Without the grants the timeframe to break even was estimated to be around 12 years - which is about the time for when you need to replace the lot anyway and start over.Some do get nice savings on their bills though but families with kids not so much...If you have little to no chance to get your investment back before you have to replace it, then it is not really that much of a good deal after all.Imagine in town with hundreds of small houses everyone would be able to get the same money back for the electricity they provide...Pay 18 cents per kWh from the grid and get 18 cents perkWh for what you supply and once you provide more than you use you get money back.The providers won't allow this to happen as it means they not just loose some money but also they would lose control.How could they justify another price hike?How could they explain the blackouts?Why should tey pay you at all... ;)If a city with enough open and unused space would decide to go solar on a huge scale and while add also add a lot wind turbines....Someone would need the electricity provided and someone need to step in for those times where demand is above supply.Here the old triangle of power goes into full swing....You see a city or town would need also need a sub station to handle the electricity and to distribute it to the town houses, shops and so on.Funny thing is that only a "provider" can do such things.Doing it privat is usually only possible in really remote areas, like big mining outposts that just have no other option than using generators or solar/wind.And in most areas a town or city is no longer allowed to be a provider of electricty - at least not in the drirect form.Buying in bulk is no problem, having your own supply system however is not in the books.Right now most, if not all the big wind and solar farms are owned and operated by energy providers.There is billionaires everyhwere who could build a solar and wind farm the size of Texas if they really wanted but they won't do it either...Starts with the land, goes over the usage rights and won't end with activists claiming how bad it all is.Means it won't happen and if it does then the energy providers get together and claim they guy might have money but does not have the right to provide energy unless he actuall starts a corresponding company and plays by their unwritten rules.Can we still dream about it though?The dream is kept alive like the fire of hope that is only a tiny amber.If you sign up for electricity you are asked if you would like to pay bit extra so your electricity comes from alternative sources.Why is that bad, after all it is green?The initial investment might be huge for a wind farm but after that it is more or less just providing mone out of thin air.You can look the cost up for the new windfarm build near you.Same for the electricity prices in that area.And also the expected output of the entire farm.Do the math and calculate how quickly they break even....Once they do it only profit but you still pay the extra to go green.A bit like the new road that came with a toll....After 5 years the motorists paid it off but 10 years later they are still being charged while the road is disintegrating...Now add electric cars and our constantly rising consumption to the mix...We can't provide the electricity ourselfs as we don't get fully paid for it, we can go off grid either.The atom as the source of electricity is being phased out slowly as well.Finally as some might say, considering the thausands of years we have to deal with the produced waste and what aftereffects the storage might bring.Our providers will keep their grip on us for as long as they can.No government will stop them as in return they wouldn't have electricity.A cold war if you like.We never cared how much fuel our cars use until the OPEC decide to limit supplies and drive the prices up.And you can see the riches especially in Saudi Arabia.For most of the big OPEC players it really does not matter anymore whether or not they have oil or not.They make the same or even more money by other means and more modern means now.After this initial shellshock we woke up and decided that for the shopping trip of the wife a small car with just 4 cylinders will do.Overcrowded cities and roads also pushed us more into thinking small.Again it took force to go further, this time by governments slowy "going green".Emmissions, greenhouse gasses, polution, particles and corbon monoxide...Sounded all godd in the ads but it meant we could no longer afford our old car or even got banned from entering the town center with it.But a lot people still can't afford a modern car that meets the standards.Once they finally got the money and car the laws change again and they need yet again a newer car.This created a huge export and recyling market and profits for other people though.And what differenc did it all make in reality?While we were forced to improve and lose money countries like the US refused for years to even consider reducing the pollution.Countries like China and Russia even increased their pollution to impossible levels.We all remember how Bejing was literally shut down for the Olympics so the athletes have a chance to survive the games...We know how the pollution or global warming problem is misused to make money.The governments get huge payouts in the form of taxes from those cars that can't meet the specs.The dealer smiles with the increased sales of cars.And again the government smiles too as they get taxes from this as well.We know it happened before and is still happening with everything realted to fossil fuels, global warming and pollution, so why would electricity be any different?Reactors and coal fired power plants are phased out with basically nothing to replace them.Solar and wind will provide and till then we keep what we really need to keep....There is no plan for what comes after coal and the atom.There is no alternative.Batteries need electricity.And providers will always be the middleman controlling both the price and the availability.So how does this actually work you might wonder...No matter who invents or produces a new device to provide electricity - there is a very limited market for them.A farmer can't buy a full size wind generator and place it on his land...But an electricity provider can buy thausands of them....And if you go bigger than ask yourself who would need a 10 or 100MW fusion generator?Providing electricity is only a viable option if you go big and if you can sell the excess with a profit margin.Leaves only our electricity providers as customers.If you don't have to care about the buying price because it will be put down one way or the other onto your customers than it is like a credit.Only difference is that once it is paid off you start to get money back!Imagine that for your bank account ;)And if you know what you sell can have a very generous profit margin because your buyer does not care then the solar or wind farm will be quite costly to build..."We know we are not cheap, but who else can deliver you what you need?"And like our big supermarkets there will be an agreement on what the wind generator can cost.Ressources....Be it wind, be it solar or just the modern electric motor in your car - they all require stuff that is very limited on our planet.Take Neodyminum.Without it we have no wind generator or fancy motors as we wouldn't have powerful enough magnets.Vital elements and mineral required are only available in a few spots on our erth in quantities justifying mining them.I won't make this much longer than it already is, so please look up what is really needed to keep our future solow and wind projects alive.Then go and check where we can find thes things in good quantities.Once you did you might realise why the world tolerates the abuse of human rights, freedom or just self expression in other countries ;)If only China would stop today to export and sell their rare earths and prcious minerals basically our entire production worldwide would suffer quickly.Entire industries break down quickly and prices for certain things would literally explode.The US already started to re-open long abandoned mining projects as suddenly even the most costly operations become viable again.Think about this next time you fancy a world free of cars and truck using combustion engines ;)

Remember the autofitting jacket from back to the future two?

My friend and I are building a functional one for our senior engineering project. We've narrowed down the solutions to servos and cables or hydraulics. However, both of these are rather bulky. Any suggestions on what else we could do or more idealy how to shrink these systems? We we're thinking about using muscle fibers to contract a bladder instead of a pump for hydraulics, but that would be expensive and annoyingg to implement.

Anti Gravity

SCIENTISTS in Finland are about to reveal details of the world's first anti-gravity device. Measuring about 12in across, the device is said to reduce significantly the weight of anything suspended over it.The claim - which has been rigorously examined by scientists, and is due to appear in a physics journal next month - could spark a technological revolution. By combating gravity, the most ubiquitous force in the universe, everything from transport to power generation could be transformed.The Sunday Telegraph has learned that Nasa, the American space agency, is taking the claims seriously, and is funding research into how the anti-gravity effect could be turned into a means of flight.The researchers at the Tampere University of Technology in Finland, who discovered the effect, say it could form the heart of a new power source, in which it is used to drive fluids past electricity-generating turbines.Other uses seem limited only by the imagination:Lifts in buildings could be replaced by devices built into the ground. People wanting to go up would simply activate the anti-gravity device - making themselves weightless - and with a gentle push ascend to the floor they want.Space-travel would become routine, as all the expense and danger of rocket technology is geared towards combatting the Earth's gravitation pull.By using the devices to raise fluids against gravity, and then conventional gravity to pull them back to earth against electricity-generating turbines, the devices could also revolutionise power generation.According to Dr Eugene Podkletnov, who led the research, the discovery was accidental. It emerged during routine work on so-called "superconductivity", the ability of some materials to lose their electrical resistance at very low temperatures. The team was carrying out tests on a rapidly spinning disc of superconducting ceramic suspended in the magnetic field of three electric coils, all enclosed in a low-temperature vessel called a cryostat."One of my friends came in and he was smoking his pipe," Dr Podkletnov said. "He put some smoke over the cryostat and we saw that the smoke was going to the ceiling all the time. It was amazing - we couldn't explain it."Tests showed a small drop in the weight of objects placed over the device, as if it were shielding the object from the effects of gravity - an effect deemed impossible by most scientists."We thought it might be a mistake," Dr Podkletnov said, "but we have taken every precaution". Yet the bizarre effects persisted. The team found that even the air pressure vertically above the device dropped slightly, with the effect detectable directly above the device on every floor of the laboratory.In recent years, many so-called "anti-gravity" devices have been put forward by both amateur and professional scientists, and all have been scorned by the establishment. What makes this latest claim different is that it has survived intense scrutiny by sceptical, independent experts, and has been accepted for publication by the Journal of Physics-D: Applied Physics, published by Britain's Institute of Physics.Even so, most scientists will not feel comfortable with the idea of anti-gravity until other teams repeat the experiments. Some scientists suspect the anti-gravity effect is a long-sought side-effect of Einstein's general theory of relativity, by which spinning objects can distort gravity. Until now it was thought the effect would be far too small to measure in the laboratory.However, Dr Ning Li, a senior research scientist at the University of Alabama, said that the atoms inside superconductors may magnify the effect enormously. Her research is funded by Nasa's Marshall Space Flight Centre at Huntsville, Alabama, and Whitt Brantley, the chief of Advanced Concepts Office there, said: "We're taking a look at it, because if we don't, we'll never know."The Finnish team is already expanding its programme, to see if it can amplify the anti-gravity effect. In its latest experiments, the team has measured a two per cent drop in the weight of objects suspended over the device - and double that if one device is suspended over another. If the team can increase the effect substantially, the commercial implications are enormous. Okay. lets throw down our ideas and see if we can figure something out... or not

I thought this was interesting: Future Edisons - on PBS

Everybody has a great idea that could change the way we work, the way we live or the way we play. Everyday Edisons documents the development process of 12 inventions and the parallel stories of the people who invented them. Selected from thousands, the 15 Everyday Edisons learn how their extraordinary ideas are taken from a sketch on a napkin to a store shelf.Take Sheldon Levinson and Michael Diep: both like to tinker with concepts for new and improved products, or simply the next crazy fad. Levinson, a true kid-at-heart, is always looking for the next best toy or gadget to make people smile. Taking the traditional favorite bubbles and combining them with the lava lamp, another iconic American gadget, he developed the latest twist on bubble toys.Diep, a refugee from Vietnam, has thousands of inventions in his back pocket, one of which is a new design for a dual cat toy and claw scratcher. As a hectic business consultant, Diep encountered a challenge many of us face lack of time. With limited personal free time, much less time to take his cat to the veterinarian for nail trimmings, Diep incorporated sand paper into his jungle gym to naturally file the nails as it played.Inventing isn't just for adults, the retired or the self-proclaimed inventor. Mark and Cody Fox, brothers and juniors in high school, were tired of paying year-end fines for bent corners and broken spines on their school text books. After combining a few fabric swatches, some hot glue and pieces of plastic, the young men developed a way to prevent the dreaded fines come June.And The Link to the PBS site

Very old shielding materials and techniques for permanent magnets and resulting possibilities

Forromagnetic meterials are not just called that for no reason.It comes from ferrous - iron.Iron has the highest permeability at normal temperatures.That means a magnet is attracted to it very strongly.We utilise this for transformer cores, the stuff inside a relay and the moving latch of the relay itself.Like current from an electrical system magnetic fields like to take the easiest route possible.Air is a very bad medium, so any iron close by will be prefered even if it is at a slight distance.You can check with a magnet, a steel bar and some iron shavings - please cover the are with plate first ;)Slightly less known is the option to also guide and extend the magnetic field this way.If you check how far the magnetic field of a magnet reaches and note that distance,then you can add some steel bars or rods at the poles - the field will extend through the metal.The most powerful example of this are the shielded magnets used for hooks or speakers.Except for a tiny area the entire magnetic flux goes through the metal.So in this lefover area the magnetic flux density will my many times greater than what the magnet alone would be able to.What most people don't know is that magnets also interact with other magnets in terms of their fields changing and distorting.The Halbach Array is a good example of this.Seen as a single magnet the array would have one weak and one strong side instead of even strenght for both.Wherever magnetic fields change a conductor can produce electricity or current.This in return causes an electromagnetic field that opposes the one from the magnets.Just drop a magnet through a copper or aluminium pipe ;)Since these distortions are widely unknow to the hobby tinkerer mistakes can happen ;)In the early days of exploring science some people already knew about shielding.And they also knew that certain metals have certain properties.Where it is quite hard to create a good coil from steel wire, copper works fine as it is not magnetic.What would then a copper shielding do?If you have two moving magnets with only a tiny gap then the resulting field distortions are quite huge.A copper shield around the magnet like a pipe would then react to these changes and also create a megnetic field that works in relation to the enclosed magnet.In simple terms it means the shield would let the magnet appear weaker or stronger depending on the field change.A quite old document I found gave some hints on how people thought in different directions back then.It was in regards to the design of a magnet motor by the way.Here various magnets were shielded in tube made of a copper-bismuth-alumium alloy.These tubes were then electrically connected so it created a single loop conductor.The claim was that the resulting electromagnetic field of this ring would drive the fields of the enclosed magnets sideways out of alignment.Like bending straight pastic tubes sideways.This "pulsating" would always happen when the magnetic binding forces reach max and so basically drastically weaken this binding effect.Another document talks about a "magnetised brass rod".A holes of the rod diameter is drilled through a block magnet.Not from north to south but through the middle where the flux is greatest.The claim here was that if that rod rotates fast enough a very low voltage with a very high current will be generated.Sounds easy and interesting enough that I might have to test one myself one day.The best one however is what I consider a hoax or being as good as Starlite.Someone back in 1908 claimed to have created a material the reflects magnetic fields.In lame man's terms it would be like an insulator around some electrical wire.The claim and some pics showed it, was that no magnetic field can pass the material.Or to be correct only a tiny fraction of what would be possible through air.A small magnet inside a longer tube of this material would create almost the same attraction to steel at the tubes ends as on the magnet itself.Measurements showed the field strength would be almost equal to a long mangnet of the same field strength.Imagine guiding the field of a big and powerful magnet through a tube around some corners or other magnets and then end in just a tiny hole for the entire flux...Too bad he never shared his secret formula to anyone knows to mankind.Isolation...Imagine you have an array of changing magnetic fields and quite strong magnets.Then you might face the problem that your focus on the "working" end neglected the other end of the magnet (stack).Providing some iron core material will keep thes field lines contained and away from interfering with your setup ;)But it also allows to use te otherwise unused end of your magnets more directly.For example by guiding to another magnet to affect its field strenght ;)Placing a sheet or steel between two magnets in a setup provides a "shared pole" so to say.If you have a north and south pole on a rotor at a distance of 5mm then a sheet of steel between will drastically weaken the strenght and reach of this combined field.It is like pulling the arch between the magnets down to make it more flat.And at and an angle the resulting field will also be slightly angled ;)Capping...When I first encounter this many years ago I couldn't really make sense of it.Quite complex..If you check the magnetic field lines with iron filings or similar then you notice how they go in a rounded manner from pole to pole.This is because the single field lines are of equal polarity and will dirve apart like opposing magnets.By capping the ends of a magnet you provide a short.Instead of diverting out like mad they will follow the cap and create very intersting magnetic field in return.If both poles are capped it is like pressing the magnet flat but without having a field on top of the oles - only aorund the center part.For this the thickness much must match what is required for the flux density.As a rule of thumb: if the end is still very magnetic then it is not enough material tickness ;)Interacting fields in a tube...This one is quite old too and seemed to have found no usable inventions apart from simple magnetic spring replacement systems.But it gave me some clues about Tesla "earthquake machine" ;)If you place a magnet in a tube and at it's ends magnets with opposing fields to the one inside then you can fix this magnet in place.Push one magnet deeper and the distance from the inner magnet to the other end will shrink the same amount.In this old paper two coils were around the pipe with the inner magnet between them.In this gap and at about the same width as the magnets length another coil was placed.Violent shaking would then create electrical energy at much higher level then modern shaker torches.In return an AC current on the outer coils would cause the inner magnet to move back and forth to create electricity in the center coil.According to the paper possible uses include: core less transformer, measuring minute changes in AC voltages, providing free power from a running motor...The last one had me stumbled for a very long time.Until I considered a different configuration.The whole thing is basically a linear DC motor - with correct timing of course.And in some motors we use permanent magnets.I am starting to wonder what would happen if we would design a rotor magnet like this?The running motor would be subject to constant field changes that affect the rotor.And a normal motor is always "even".By using four magnets instead of one we can push the field really flat.This means the area where the coil would operate (about 1/5 of the magnets area) will have a much stronger field.The resulting torque should be higher by about 25% !!Even a simple two coil model setup should show a significant increase in performance here.Timing is critical here but I tried some calculations based on 8 poles and the required "on times" for the coils.In a standard motor configuration with a single rotor magnet the coil is active for about 12° of the rotation.With a 4 magnet configuration this "on time" can be reduced to under 8° of the rotation to get the same amount of torque.An energy reduction of about 4% if you neglect losses and only think in time.If you think in terms like impulse energy then we are talking of about 15% !Shorter on time but still much higher flux density overall than for the long standard timings.Going the long run now:If you check how most DC motors work then you realise soon that for most one rule seems to followed.Only use one coild pair at a time.This is quite contradictive if you consider the geometry and options.A dual commutator would allow to use a second coil pair with a field OPPOSING the magnets instead of being attracted to it.After all: on you bike you pedal with both legs and not just one...And if you do it professionally then yu do the same as I suggested for the motor - you use the up pull of your legs as well.Doing it brushless only requires amodified h-bridge desing to drive the second coil pair at the right timing.Some will now say that it requires twice the energy, I say that for the same motor size your get twice the torque!Just imagine what that means in possible weight reduction for a motor - or its size to deliver the same torque at the same power levels when a normal motor is used ;)The more poles the more complicate the precise timing but no big deal really with modern electronics.Can it be improved even further?I though long and hard about that one until I considered EMF.A DC motor produces a lot of it when the elecromagnetic field collapses in the the coils.We do not utilise this energy...There is a tiny delay until the released energy levels are at max.My theory is that it should be possible to divert this energy into another coil set.If that coil is not the next active but still within a strong enough field area then the EMF would actually add to the drive of the motor.Only downside is that according to my calculations at least 16 poles would be required to get an optimum result.Way above of what I can create in my little garage :(In theory it should then be possible to reach about 98% efficiency for the motor....

An answer would be really helpful to me, as I'm looking to upgrade my computer's video card sometime in the future, but can't get inside the certain part of the back of the computer case, as I don't have the right tool to unscrew button screws.

New Years 08: How We Could Theoretically "Discover" Time Travel/ers

Well that forum on time travel got me thinking...How We Could "Discover" Time TravelWrite down, carve on stone, burn into our memory, tatoo on my back, or something, that if/when time travel comes into exsistence, someone needs to travel back in time to a specific time and date in our near future (Instructables Control Tower, New Years 2008 would be a good time/place). If everyone were to record this, eventually someone/s might do so, meaning that a time traveler might turn up at Instructables HQ on New Year's. I personally intend to attempt to do so, or at least get my future kids to:)Anyways, if a good number of people do exactly this, there might be quite a congregation at Instructables on New Year's. Or of course, no one might turn up at all...

A central non-electric grid electricity storage system for solar and wind energy with future expandibility

I have been thinking and reading about building a system so that I could surf using a laptop, charge lights, charge mp3 players, mobile phones, rechargeable batteries so that if possible they would not need electricity from the grid, rather that would be optional when there would not be enough power that was found otherwise. I had first thought to work this out in a group as a kind of project, as there are others but I don't really know that many people with those skills. The idea is that you start very basic, with say one solarcell and the electronics. The electronics should allow plug to when you wnat to have the money you can add another, in serie or parallels so they give more power. This can then be plugged in to a system that stores that electricity in batteries. The system should also be so that it allows to connect for example one or more small selfbuild wind turbines, like the ones found here, so that in the best case you get electricity from both, or one of both but with the possible option to get electricity from the grid so that if necessary you can charge something from there. That would mean it would include an electricity meter, and maybe the possibillity to add that self powering powerplant as well.So basically you have two projects. Or maybe three. The casing to add small solarcells in, and then be able to add several casing together. The electronics to put them in serie and then a central electronic system, which allows to connect solar casings, self build windmills, batteries, the self powering power plant, possibly the possibility to add it do the grid, and last but not least the possibbility to charge things. That could be a seperate part of electonics. As one of the things I had been thinking about is to allow to connect fuel cells to it. I prefer us in what already exist, so I would suggest using the following instructabels projects or learning from them:a Savonius Wind Turbine,Ted Baer's Bicycle Wheel Windmill, savonius windmill alternator,introPringles Wind Turbine,DIY 1000 watt wind turbine,A remote controlled power RGB LED mood light,Power LED's - simplest light with constant-current circuit,Circuits for using High Power LED's,personal powerPlant, ... others may follow laterLike for example the Charge Any USB Device by Riding Your Bike but then connected to the portable usb batteries, so they could be also connected to the central charge unit. The connectors could be usb connectors. I saw some time back a connector which had a 4 port usb block attached to it, but other connector types would be usable as well. In adition, it should be able to switch on automitcally when the sun goes down, but allow a control a button or remote control to trun them manually off, so that no needless electricity is wasted. I know this is a lott at once, but its more my kind of thing to work on more complete/complex systems. The lights that would be used with this would be led lights, powered a la sunjar, using the same technique. So that them turning off and on, is mostly controlled by the sun going up and down. My idea was that with such a system, I could add piece by piece, and still have light, and electricity indepency from the grid, and I would know the cost, so that once I would have bought the pieces it would generate electricty whitout to much further cost.Solarcells would typically provide 8V or 12 V, this could be smaller ones, the casing would be is supose made of plexiglas, with pieces that standup to keep them appart, and holes for the cables, and a backside, that stays dry as well. This is what is on the drawing: the solarcells feed into the sersol which puts them in not parallel and then transport the current to the cen1 which directs it to the batteries to store it. The same for the windmills. But they go to the windmills, which puts there current in not parallel. The powerreg, regulates the power of the personal power plant, it can discharge, but also just regulate. There is connector to the grid, so if there is no electricity or not enough electricity it can be taken from the grid. There is the possibillity of a remote, which would work in connection with the cen1. The batteries might need extra electronics to see which one is full and to divert the current to another battery, and to get current back to the powersockets which could be regular oens, but also preferably usb ones. The other two connections could be for for example fuel cells, or something else. The control solar cells is simply to turn the connected sunjars which may still each have there own solarcell, on or off by the rising or going down of the sunn. The remote, is to turn them off manually.The casing should be sturdy but not to expensive, it may have to include somethings to keep it right, but the idea is to be able to put them after glass as well. The idea is that the electronics design would be free, or very cheap, so that people can build this themselves, the casing shouldn't be to expensive but that can differ on taste, most parts or thing likes windmills would be the DIY type or possibly ones you can buy as well, and most parts would have to be, off the shelf. I'll try to add a basic drawing, and some sketches, to give you a better idea. I'm not that good at that, i'd admit.

How discover time travel... i think

Long story short, my friend found some instructions of how to create a time machine or something. The drawing looked kind of dirty so instead of keeping the drawing, she just took a photo of it. She showed me the photo, which turned out to be real blurry and crappy.I posted the blurry photo up on this site, and someone commented that the original image is on a site called asiko.org It's some weird $h!t. I emailed them but never received any word back as to who is behind this. But anyway I figured to post the instructions here because it does seem feasible. The plan is basically this:1. Choose a date, time and city. These 3 things are called Asiko. Let's use 01/01/09, Time Square NY, New York just for clarification purposes.2. Popularize Asiko till step 53. Meet at Time Square on 01/01/09, and we should see a time traveler from the future4. In the unknown future, a time machine will need to be invented. Still popularize Asiko, 5. When they figure out how to have "safe time travel", a traveler will be sent back to the popularized location and time of Asiko, which is Time Square, 01/01/09.

UTF-8 Bugs

Adding extended UTF-8 characters to Instructables works the first time, but if I edit the page, the editor replaces them all with broken characters instead. I have to manually edit all the characters back before hitting save, or the broken characters are propagated to the web. The characters that I have tried are capital omega (Ω) and the degree sign (°), and I plan to use lower-case mu (μ) in the future. Also, the bug posting form seems to be much more broken in this regard.

Pretend to be a Time Traveler Day - Dec. 8

This sounds like loads of fun: Pretend to be a Time Traveler Day!Scheduled for December 8, 2007. Just spend the entire day in costume and character, but don't actually explain what you're doing- context, costuming, and behavior are key! Never admit you're a time traveler, and make really, really bad attempts at keeping a low profile.Three options:1) Utopian/cliche future- "If the Future did a documentary of the last fifty years, this is how badly the reenactors would dress." Think Star Trek: TNG or the Time Travelers from Hob. Ever see how the society in Futurama sees the 20th century? Run with it. Your job is to dress with moderately anachronistic clothing and speak in slang from varying decades. Here are some good starters:- Greet people by referring to things that don't yet exist or haven't existed for a long time. Example: "Have you penetrated the atmosphere lately?" "What spectrum will today's broadcast be in?" and "Your king must be a kindly soul!"- Show extreme ignorance in operating regular technology. Pay phones should be a complete mystery (try placing the receiver in odd places). Chuckle knowingly at cell phones. 2) Dystopian Future:- This one offers a little more flexibility. It can be any kind of future from Terminator to Freejack. The important thing to remember is dress like a crazy person with armor. Black spray painted football pads, high tech visors, torn up trenchcoats and maybe even some dirt here or there. Remember, dystopian future travelers are very startled that they've gone back in time. Some starters:- If you go the "prisoner who's escaped the future" try shaving your head and putting a barcode on the back of your neck. Then stagger around and stare at the sky, as if you've never seen it before.- Walk up to random people and say "WHAT YEAR IS THIS?" and when they tell you, get quiet and then say "Then there's still time!" and run off.- Stand in front of a statue (any statue, really), fall to your knees, and yell "NOOOOOOOOO"- Stare at newspaper headlines and look astonished.- Take some trinket with you (it can be anything really), hand it to some stranger, along with a phone number and say "In thirty years dial this number. You'll know what to do after that." Then slip away. 3) The Past:- This one is more for beginners. Basically dress in period clothing (preferably Victorian era) and stagger around amazed at everything. Since the culture's set in place already, you have more of a template to work off of. Some pointers:- Airplanes are terrifying. Also, carry on conversations with televisions for a while.- Discover and become obsessed with one trivial aspect of technology, like automatic grocery doors. Stay there for hours playing with it.- Be generally terrified of people who are dressed immodestly compared to your era. Tattoos and shorts on women are especially scary.

Most of the time, I try to use the "date and time" stamp, but that's problematic since the time is computed on the fly in my local TZ. It's worse if the comment is embedded half a dozen layers down in some thread in a completely different Forum Topic. Once or twice, I've tried to use "View Source" in my browser, and search through to find the corresponding markup for the comment, and then extract the hash from one of the tag/JS attributes. Since the information is already there, would it be difficult to add a "link" hyperlink to each comments, such that the returned URL was the one needed to get back to that comment in the future?

Vimeo inclusion quirks

It seems Vimeo and Instructables are not the best of friends just yet. I hope they are working on these issues so that including our Vimeo hosted videos is a less frustrating experience in the future. Only If you use the new editor you can embed video with the Vimeo URL, or even simply posting the link in the body will place your video. Save right away. But then... anytime you open your Instructable to edit it moving forward, Instructables removes the video and saves the Instructable (Awesome). You'll have to add it back in again and save for it to reappear. Youtube quality is always improving, but the ad-free playback and greater controls makes Vimeo a winner in my book.

Eye-fi Eye Films now a Thanksgiving contest prize

Instructables just received some beta Eye-fi Eye-Film cards. These amazing little devices are SD-memory-card-shaped packages that go in your camera and wirelessly upload images. Right now, the awesome people at Eye-fi have a few of the major photo-sharing and photo-storing sites integrated with their service.I took a picture of numberandom in the shop, and before I got back to my computer, the image had been uploaded here to my Flickr account, geo tagged, and placed on a map. Holy cow that's awesome! Now, I will admit that right now the integration with Instructables is quite lacking (I had to download the image in this post from Flickr and reupload it to Instructables!). However, I'm sure everyone can see the direction this wonderful piece of hardware moves us in -- one step closer to the Memex! "One can now picture a future investigator in his laboratory. His hands are free, and he is not anchored. As he moves about and observes, he photographs and comments." More here and here.In the near future, you'll be able to just take pictures and have them automatically appear on the web ready for use. Anyone remember developing film pictures (and maybe scanning them)? Hopefully, uploading will soon go the same way. We have three of these that we're giving away as Grand Prizes for the Thanksgiving contest. So, if you want to take your documenting and picture taking to the next level, you'll really need to take Thanksgiving to the next level.

I'm having trouble finding the right material for a full head mask. suggestions? Answered

I get bored, often. And to pass that time i make goggles and masks, until now ive used leather, denim, hard plastic, metal, paper mache, and even clay. I've been inspired by this game, Gotham City Imposters, to make a "homemade" version of batmans cowl. I'd like to make it out of a material that i guess would have to stretch, cuz i just want to be able to slip it on and off, you see, all of my full head masks ive made so far have either had belts or laces in the back that id have to do up and undo everytime i took it on and off. So my question for this project and future ones is... what the lump should i use (as far as materials) that would be tight (not too tight) and be easy to slip on and off my head, without breaking or tearing?

Overly Featured Authors

I'm happy to see the ladies on the front page and their work is fantastic, but I'm on the site every day and it seems that 75% of the time I am seeing giannyl (published in March) and 25% of the time jessyratfink (published in May).  I haven't see the April dude on the front page once.  Did you have a "Sexy Bunny vs. Guy Who Dresses Very French" focus group? How exactly it this rotation determined and why does it rotate back to one person?  Is it based on views? Regardless, perhaps it could be changed up a bit to allow other authors some front page time? And just a quick aside on the 50s era wording "much more than a pretty face"...Will you please continue to reference how authors look in future features?  I would love to see "For a handsome dude, this guy sure knows a lot of math!" or  "This moderately attractive author has created some gorgeous pieces" or even "At least his soldering iron is hot."
