Secret Pal

So I was thinking, what if we managed to have a sort of secret pal each year around the holidays. Where there's is a random generator that picks names and is given out to each person. Then we would buy a gift for that person ship it off to wherever they live. But there would be a minimum and maximum so someone doesn't send a piece of paper or a laptop. Like $15-20. So what are your thoughts?

secret boxes

Hi! I'm a letterboxer. I bet a lot of Instructable users know what that means. Every year I host a big Halloween event. I'm already in the planning stages for 2015. The theme is Twin Peaks. Mysterious stuff hidden the woods -- perfect. Anyhow... with the idea of building interest ahead of time I had a brainstorm of riffing on the backstory from the actual show that Cooper had been involved in an ongoing investigation long before Laura Palmer's murder. So I'm thinking of using a blog to put out a variety of clues, logic puzzles, visual things, whatever, that will fall into place at the actual event by allowing people to have access to.... to.... I would appreciate references to your favorite "secret box" instructables...things that you would need some code or something to get into. Thanks in advance....

Solenoid secrets?

Folks, I recently purchased some inexpensive 110Volts AC solenoid coils from China through eBay (of course.)  As I understand solenoids will convert electricity into linear motion.  I have been unable to do that.  I tried ferrous rods as plungers, they get stuck inside the walls of the coil's cylinder.  No ferrous material like aluminum rod did not work at all.  Can someone please guide me to make it work.  I purchased 110 Volt coil thinking that it will create a stronger field, I don't feel the strengths of magnets to be rather weak. 1. The coil gets hot when energized.  Will it burn out if I keep the solenoid energized for 4-5 minutes? 2. Should I go for a lower voltage DC coil? 3. What happens to the dc coil if energized for long time? I would greatly appreciate your comments. Thanks.

Secret To Slithering Is In The Scales

Secret To Slithering Is In The ScalesTalk of the Nation, June 12, 2009 -- How do snakes slither on smooth surfaces? Mechanical engineer David Hu, of Georgia Tech, filmed snakes slithering up inclines, outfitted them in jackets and photographed them through jello to better understand snake locomotion. The researchers published the study in the early edition of the Proceedings of the National Academy of Sciences this week.NPR's video that accompanies the article has some amazingly fun shots of snakes slithering in place on surfaces too smooth for them get any traction.

Kiteman knows a secret!

Instructables is going back into the publishing business! OK, so it's not much of a secret, what with a bunch of people getting emails about their projects going into them, but individual comments are building into a bigger picture: Instructables is following up The Book with a bunch of eBooks - a BIG bunch of eBooks. I don't know the titles, yet, but there are going to be... (counts on fingers, runs out) more than several (in aPub format, maybe Kindle too?).  Did you get an email?  Are you going to be in one of them? If you find out a theme or title, add a comment. Can we work out what they all are before The Powers That Be let us know officially? Oh, and get this - at least some of the several will be free for pro members to download!  Now there's even more of a reason to post a cool project that could get freatured - a helping of free pro-ness would come with a side-order of eBookiness! (K'NEX?  Surely not?) Yes!  They're on the Kindle!

Secret playroom behind wardrobe

This wardrobe is actually a secret entrance to a playroom. The owner of the house had the wardrobe and figured he might as well add a touch of magic to the house for a pretty amazing result. This reminds me of an apartment I once visited in San Franciso. There were two refrigerators in the kitchen. One was normal and the other was a secret door. Walking through it led you to a dark hallway that ended in a small room with a single chair in the middle and a single lightbulb hanging down over it. Creepy as hell.

secret boxes for the outdoors - revisted

Hello, Instructibles gang…. I posted several questions related to “secret boxes” over the weekend. I got some feedback suggesting that the inquiries should have been combined, and that they didn’t include enough information to lead to worthwhile answers. The topics came to mind sort of haphazardly, so I do apologize for the scattershot nature of the original posts.  As to the latter issue, “secrecy” was never the intention… rather, it was that this is all still in the “doodle” stage of planning, and I didn’t have a lot of details to give in the first place. Nonetheless, I’ll try to get a little more concrete - and combine the three questions in the process. I’m a letterboxer. Letterboxing stuff comes up now and then on Instructibles, but for those who are unfamiliar, it’s similar to geocaching (which seems to be more well-known), but with an added, artistic component. Whenever I see “secret boxes” in my regular Instructibles emails I think about whether the designs could be adapted for letterboxing purposes – either “on the trail” or at limited-time events and get-togethers. Naturally, I’ve been looking through my bookmarks and doing Instructibles searches, google searches, etc., but I’d appreciate if anybody might be willing to point me toward some of their favorite designs. I’m increasingly interested in creating boxes that are “hidden in plain sight” – not concealed, but rather “hidden” by virtue of the fact that they look like something else – such as a birdhouse or mailbox – and might in fact actually BE that something else, in addition to being a hiding place. I would welcome any suggestions that the community thinks might fit the bill. Here are some of the preliminary ideas I’ve been thinking about: 1)      Folks hunting the box are told to take a 9v battery, with the snap-on wire leads, with them. When they get to the box they have to put the leads into two holes, where they and the battery complete a circuit. The current trips some sort of latch, allowing a door to be opened. Of course, the door would have to re-latch when closed again. 2)      Something similar to #1 but a little more electronic. Hunters might be given a schematic of a simple Thing that they have to build and take with them. This would, essentially, be a key. I’ve already received an interesting suggestion involving RFID chips. I also got to thinking that a USB connection could be very discreet and easily hidden, and THAT got me thinking that the “key” could perhaps be something on a smartphone… data rather than hardware. I’ve got basically no background in electronics, but I’m fairly good at following directions…. 3)      Pretty much any other contraption where some sort of hidden compartment would be created, which can be accessed through some sort of process that likely wouldn’t happen randomly or accidentally. (I know… could I be any more vague?) The boxes would likely be mounted to something solid - a tree, wall, post, etc. - but I imagine it could be that you take it down, do what you’ve gotta do, and then put it back. And they would most likely be exposed to the elements and would have to stand up to being out of doors. The size of the compartment is entirely flexible…no minimum or maximum dimensions.  And, as stated, I’m a beginner when it comes to electronics – but I am more than willing to learn! I know what I’m trying to describe, but please let me know if I’m not doing well in communicating it to others. Like I said, I’m not trying to be secretive. It’s just that it’s still a very open-ended scheme – not many specifics – and I’m interested in hearing how different folks might approach it. Please shout if you have any thoughts or want more info.

Secret Message Revealed After Wet

Does anybody know of a way to have a paper with a secret message on it (pretend the message says, "It Rained"), and once the paper has been soaked with liquid (water, or maybe a mild acid or base), the secret message is revealed permanently? So like, if you had a little paper sign out in your yard with the secret message, and it rained, and the paper got wet, when you come home, you would see the dried out paper but with the message revealed. (note, i don't actually care about a "it rained" indicator, just an example)

The secret knock detector workshop door

Check out this great knock detector build by BFarn. It was inspired by the great secret knock detecting door lock ible by Grathio I'm extremely impressed by the design and technique's he used to make his own knock detector. I mean Grathio's detector was already awesome but this one just makes it a beautifull piece of art and also limits the area where can be knocked (which is a plus on security for me). So even when somebody accidently overhears you knock they still won't know where they should knock to get the door open! Check out the video to see it in action and for more info on the build you can visit his website here

The Secret Service is Calling Me! Help!!

Hi Friends,Recently someone has been calling me on my cell phone about 3 times a day saying they are the secret service from a private Caller ID. It is someone from my high school. I think they are using a spoof card because the phone number is blocked or the white houses number. It is really starting to piss me off and I need some help. They have called about 7 or 8 times in the last 2 days. Its really annoying. I called sprint to see what they could do but all they said was that I would need to contact local law enforcement to put it to a stop. The worst part is they are not only wasting there own and my own time but they are also working away at my phone bill. So, I need your help. What do you think I should do, contact the local police and get the perpetrator(s) arrested for impersonating a government member or should I try something else such as taking the law into my own hands (phone trap/ back spoofing)Thanks for all your help.Joe Rowley

The secret to storing Loquat for wine making!

If you don't know what Loquat means then just look it up on Google or Wikipedia ;)Mostly used as ornamental trees in the warmer climates Loquat fruits come into season right when the summer is on your doorstep.Although the fruits are delicious and high in nutrients, vitamins and so on: Most people do not even bother to try them :(So if you spot them please give the fruit a try and you might get hooked as did.The biggest problem of using Loquat for more than a direct snack is not the seeds inside.They are quite big and you figure ways out to get around them.Biggest hassle is how the fruits ripen.Unlike most real fruit trees there is fixed time.When the first fruits are ready then the last migh be ready about 3 or even 4 weeks later.And depending on the local wildlife you really need to check daily for ripe fruits....So how to do it properly then?Loquat goes bad really fast no matter what you try.Eat them quickly as otherwise they go off.Don't bother...Those are common answers you get from people who had those trees for years in their gardens.The trick however is really simple:Do not plug them off, cut them off!Some half decent pruning sizzors work great here, especially the smaller types.Cut the stem of the fruit so at least 5mm are left on the fruit.Without the hole from ripping the fruit off and handling it with gentle force there will be no damages or open areas ;)Like that the fruits stay fresh for a few days in your fridge, just make sure they are kept quite loose.Do not just fill a big box with them and hope all fruits survive the pressure ;)If in doubt layer them on soft foam strips or cardboard - works really well if can find complete clusters that are ripe enough.If you have access to more than one big tree you can get enough to even make a really nice wine from it.You need to be quick though, so let me tell you how I do it:Prepare a big enough fermentation vessel, in my case a 25 liter plastic drum, purpose made...Add about 10 liters of warm on prefably filtered water, some sugar and a good amount of your prefered brewing yeast.My personal favourite here is port wine yeast ;)You should prepare this drum once you can collect enough ripe fruits on a daily base.Prepare the fruits by removing the stems, the hard spot at the bottom and then cutting them in half.A small spoon can be sharpened to help to get the seeds out if have some with many little ones hiding.Have a pot with boiling water ready and put about 250 to 400 grams of prepared and cleaned fruits in it per load.A quick heating is essential as you want to keep the cooking time as low as poosible.90 to 120 seconds should be enough to get the heat throughout the fruit - please check every now and then that the fruits are quite soft now.This step is vital to prevent self fermentation - you only want your yeast cultures to work on the fruits ;)Squash the fruits when adding them into your drum.To make a full 25 liters with just a table spoon of sugar at the start you will need about 10 to 12 kg of fruits for a high volume and sweet result.The best option due to the constantly changing sugaar content in the fruits is to go with the flow.Stick to max of about 15 liters per 25 liter drum.Monitor the sugar content and alcohol level.Port yeast dies off at a bit over 14%vol of alcohol.Although some strong ones go up to 18% here...If the alcohol level goes over 10% while the sugar content is still quite high then you add water until you get down to about 7%.If the sugar content goes down too low you add more fruits.With still enough active yeast you can even transfer half oa drum to a new batch once the drum is getting too full and the sugar content is still too high.Just a matter of getting used to working with ongiong adding of fruits and water to compensate the time it takes to get enough ripe fruits.Of course there is always the option to go low and start with 5 liter canisters instead....

Using a laser pointer to display secret shapes?

Hey, all, I'm working on a puzzle for an escape room right now and am wondering if there's any way that I can use a laser pointer to display a number. My hope is that the number is not on the lens of the pointer, but rather is discovered after the laser pointer is shined through a specific spot on a piece of plexiglass. The players are asked to set up a tripod in a specific spot with a specific angle, mount the laser point to the top of it and then move the point around the room. Ideally, as the point is traveling around the room, it will shine directly on a small part of a plexiglass display and then refract a number on the wall behind it. Any ideas on how or if this is possible? Any and all thoughts are welcome. Thanks!

Help me make a bookcase door to a secret room

  Inappropriate Incomplete Spam Scooby-Doo movies became famous for it, spy movies have been known to have them, Batman had one, and yet... I used to live in Kansas, before I moved to Arizona, and while I was there I visited a place called Science City. It is basically an indoor amusement park with funky gizmos like a hologram of a fist sized diamond behind a painting, and a rocking chair that doubles as a power generator. But the thing that interested me most was a wall that revolved at the center, becoming a door that would lead to another room. I asked some of the employees about it, but it must be a trade secret since they all said they couldn't, or wouldn't tell me. One of them even denied the existence of such a wall! Ever since then, I have seen various recreations like this in spy and mystery movies. I think that this would be the coolest thing ever. You see, when you turn the wall around, one side is a fake bookcase, the other is a blank wall. It turns 180 degrees, then you have to turn it the other way. I want one of those in a cabin that my family is building up in the mountains. Since it would have to be custom built, I would need a very good idea of where to start. Anything in the way of advice, answers, or even speculations anyone could give me would be absolutely great. Sincerely Yours, Zelback1

Need Ideas For Collapsible Lightbox For SECRET Engagement Idea :)

So, I've been dating a wonderful girl for a while now and in the relatively near future I would like to pop the question. I have a clear idea of how I'd like to do it but need some expert crafter advice to pull it off. My idea is a fairly innocuous guerrilla art installation which was inspired by the Banksy paintings he surreptitiously installed in museums. I want to surprise my lady by taking her to a museum and having an accomplice quickly deploy my idea in gallery for us to "stumble upon". My idea is for a lightbox, suspended from a tripod. The illuminated box will have pictures of us on all six sides and the top will open and the ring will be inside. I've made simple decoupaged cardboard lightboxes before, but this time it needs to be something collapsible which will fit in a messenger bag or something similar. My current thinking is to have the six sides of the box be plexiglass squares attached to one another with hinges. The sides would all be hinged to the bottom center piece. The front and two sides would then fold up to make the front and sides of the box. The rear piece would be two lengths of plexiglass attached to fold up and over making the back and the lid of the box (see very rough sketch below for my idea of how the pieces would be hinged). What I'm looking for is suggestions on: What materials to use for the box itself and types of hinges (is plexiglass/lexan a good idea?) and how to attach the hinges to the box (glue?) A way to make the sides all stay up once they are folded into place (I was thinking perhaps loops on each side piece you could slide a small dowel through or something) And anything else you might want to suggest. Again the goal is to be able to bring this thing in without attracting attention, assemble it very rapidly, and be able to break it down quickly once everything is done. If I can pull all this off I'll document the process and post it here. Ideas?

"Secrets" about CB/UHF antennas on your car

Despite more and cellphone and internet coverage mobile radios are still a favourite of people in remote areas or just loving to explore by 4WD.And for most the complex task of starting with this great hobby ends by buying a radio and antenna.Of course the raio goes it fits best and that is fine but what about that antenna and while at it what type of antenna do you need?Let's start with the great myth that so called rugged or heavy duty antennas are really worth their money.Durability and stiffness is their main selling point or better was.At highway speeds they won't bend and flex around like your whip antenna.In the bush they won't swing all the way down onto the painted parts of your car either.But then again, a more solid steel whip on a spring base would do the same - but won't look as cool or proffessional...Inside those plastic or fibreglass rods is a dipole antenna, in rare case you get a 5/8 configuration or even a normal steel whip with a pipe around it...Means in terms of reception or transmission quality they are not a tiny better or worse than any other antenna out there.Come down to well it is tuned and where the radiating part is located.Location...There are often obvious choices to put an antenna, like that nice mount or your nudge- or bull-bar.Or the good old boot clamp in the back.I have even see 4WD's with the antenna mounted onto the rear bumper :(Why is it so important to place the antenna correctly?Place on the front corner of your car it is not only quite low but also partially covered by the metal parts of your car - limiting where the antenna can properly radiate.If you ever got some half decent training on a tiny handheld UHF radio then you remember to seek higher ground if you can't get anyone to hear you.The same is true for the antenna on your car.You want nothing obstructing it.People with a long spring base often think of it as just an elevated foot.Most of these however are "ground idependent", which means they actually form a dipole with the antenna you screw on the top.Having this "pole" below bonnet hight is quite bad for your reach and reception quality already.Mounting just a normal whip on a direct foot here means you might have better luck with a handhelp from inside the car...The best would be right in the center of your roof, the highest and most centered point.This provides not only the optimum radiation pattern but also give you that little edge in terms of higher ground.How much gain do I need and how long should my antenna be?Gain is quite relative if you ask me as it far more important to mount the antenna in the best possible place.A 3DB antenna on the roof will often provide better reception and range than a 9DB mounted on the bullbar.Assuming you have the best feasable location than to simplify it:The further you can see the higher DB you want if reaching far is the main objective.For general use a 4.5 - 6DB antenna is always good.In hilly terrain range does not matter that much, here you want the outgoing signal to be as strong as possible and with a shape that allows better coverage by being more like a sphere.For extreme cases it can mean on a 9DB antenna your friend that is just over that little bump ahead is not visible and with that can't hear you.On a 3DB antenna however the signal is strong enough to reach that blindspot at a short distance.The overall length of an antenna can be deceiving for UHF frequencies.What matters is where the antenna is radiating from.In most cases it will be the top 15 to 30 cm of your antenna.For a dipole or ground independent antenna you often need to include the entrire base mount.Antenna tuning....For the good old 27MHz bands we always had our SWR meter at hand and tried to get the best tuning.Since the big jump to UHF the commercial antennas come pre-tuned and are claimed to be good to go.That means that are within acceptable performance to fit almost all installation locations.In terms of SWR reading it means that 1 over 3 is still perfectly fine.Would have been an outcry on 27Mhz though in my times.What is true though that there is not that much real difference to notice between a near perfect 1 over 1.1 to 1 over 3.If you would bother to a distance test it might be less than 200m you gain on the near perfect antenna.For the reception it does not even matter all, so why bother anyway?On the much lower frequencies a really good SWR does not only mean you can get your signal much further out there but also that your transmitter is happy.Modern ones are now all digital and have ways to protect and compensate for bad antennas or cables.Together it means we could just forget about these few extra meters and move on.The stress on the transmitter in your UHF radio however is still there ;)The reflective energy from a badly tuned antenna has to go somewhere and that is usually back into the transmitter.The bit that lost directly to your antenna, as said, does not matter too much with the overall limited range of the UHF frequencies.I did quite a lot of experimenting with my own and commercail UHF antennas, so a network analyser and SWR meter was a requirement anyway.In terms of output power a good SWR reading means you get what your transmitter is capable of and set for.With an SRW reading between 2.5 and 3 however a 4W radio might only actually transmit 3-3.5W.With a bad mounting and an not so optimal cable it might go below 3W!Distance is not so much affected by this as we now know, but the loss in power on 3DB antenna in hilly terrain can make the difference between being heard and your signal getting lost in static on the other end.Repairing a blown transmitter often costs more than a simple SWR meter for UHF, so why not add it to the Xmas wish list? ;)Two antennas...In some case you want two antennas.Be it for two different DB ratings on the same radio or for totally different frequencies.High and centered is still best here but you should keep the antennas as far apart as possible, preferable at different heights as well.On a single radio it does not matter too much but right next to each other the unused anteanna is like these beams on your TV antenna on the roof.Unlike the directional and watned features in a Yagi antenna the unused element means we change the radiation pattern.In the worst case creating a blindspot from which direction we won't get any signals.As a rule of thumb let them be apart at least twisc as far as the wavelenght, so for UHF over 65cm.

The dirty little secrets about switching to LED lights

Some years ago we were told to invest in more energy efficient lights for our homes.Incandescent was using too much power, so CFL's, Compact Flouroscent Lights were the ting to buy.Much higher price than the normal lightbulb but hey we save a lot of money in the long run.No one liked the long warm up time to get full brightness...And even less people actually got the claimed lifespan out of them.Add the recycling costs and hazardous waste created and the costs of using CFL's is actually much higher than standard light bulbs.The only savings were for the power companies.LED lights had a slow start but once mass production started price went downhill fast.What started in the EU was made compulsory in other countries soon after: A ban on incandescent light bulbs.Thee are only a few exceptions left like bulbs for your oven as LED's won't cope with the temps here.So why was the ban necessary?An incandescent light bulb was available for often under a buck, so having some spares at home was no issue at all.Making people switch to LED lights that often cost 20 times the amount of an old standard light is impossible.Biggest incentive of course was the short boom to the local economy as the initial batches were all sold as high quality items.The scam started to evolve when it became clear that even with LED lights the overall savings hugely depends on how you use your lights.As a factor on your electricity bill the lights are usually at the bottom of the list.Things like heaters, airconditioners, fridges, freezers and of course TV's are the main users of electricity in many houses.During the winter times this changes as we need more light but still the impact is not as high as you might think.What did change though was the behaviour.Since we now save so much energy we don't really worry as much if the light is kept on for no good reasons.Again, the main savings are with the electricity providers.I won't deny though that a house with 100 60W incandescent lighs will have some benfit on the electricity when switching to 8 or 10W LED lights....Lifespan...Like so many others I have some stories about incandescent lights...For example the one had in the basement when I was a kid.Often on for several hours, sometimes just for a few seconds to quickly grab something.But it still worked fine when I was an adut and never had to be replaced.Or the house that destroyed lights on a regular base thanks to power surges from the nearby industrial areas.LED light were meant to make the difference here.Put them in and never worry about replacing.10.000 or more hours before the LED's fail...Nice claims but never fully true.10.000 is a bit over a year of constant use.Most people won't just leave the lights on for the entire year.So you would expect that a good LED light will work just fine for at least 5 years, under normal conditions close to 10 maybe.There is several problems with this claim - none of them are explained in the warranty leaflet and nothing was explained by your government when you were forced onto LED light.Electronics even as simple as a resistor come with a limited warranty.Some will remember the disaster when bad capacitors turned thausands of flat screen TV's into flashing lightbulbs.The parts used to make the lights can be a year old already before they are soldered together.Then there is time for shipping, storage, distribution.Sadly not all countries require to print the manufacturing date on the packing or LED light.Means that by the time you put a new LED light bulb into use it might be two years old already.Similar for the claim that the light won't emit heat.Sure the LED light itself is cold but the heatsink the LED's are mounted on is far from it, same for the often underrated electronics inside.In return the electronics suffer from the excessive heat, espcially if mounted in lamps not designed for them.Which makes the entire replacement a scam for most people.It is not uncommon that a LED light fails within a few months.If you are lucky to have kept the invoice for it you might be able to get a new one from your store.Now I replaced 20 lights when I moved in here.Only the first three that failed got replaced, after that the shop claimed I would misuse the warranty.I inspected them and it was not easy to get inside.The switching IC used should have had a heatsink according to the datasheet, without it the circuit board got toasted until the IC finally cracked.Without a sufficient heatsink the IC was only rated for a max of 5W while the light had a LED assembly of 15W...I kept doing these destructive examinations whenever a LED light fails.So far they ALL had sure signs of overheating, either for the switching IC or the tiny transformer.No one really bothers though to keep track of the hours a light was actually used and with that we just keep buying new ones with no worries in the world.Recycling....An incandescent light was never really worth much to begin with, so the final grave was the normal rubbish bin.CFL's required proper disposal due to the hazardous materials in the tubes.A comparison between the amount of sold lights and what ended up in recycling centers reveiled that the ,ajority of them ended in landfill because people tossed them in the normal rubbish.The long term impact of those chemicals on the enviroment will be hidden under fresh grass by then.LED's claimed to be the way out as they were meant to be fully recycleable.What really happend with our collected recycling bins was clear when China stopped taking it.....Means all the still usefull materials in those expensice lights again just go into landfill.A total waste on so many levels.So what is the real cost then?Electricity prices are only going up, so saving Watts wherever possible is a good thing.But ask yourself:How much energy and ressources were required to produce an incandescent light bulb?How much more is required to produce a LED light?We are told to focus on our electricity bill alone without considering the overall costs.Since we already pay the extra of making them we tend to forget what happens once they fail.More waste, more landfill, no recycling of the lights at all.But does it prevent your next blackout when the grid is at max capacity? Nope...Keeping your big airconditioner off for a hot day or two would save more electricity for the year than changing from incandescent lights to LED's ;) Does that mean we get way more efficient airconditioners? Nope...Where in developing countries cheap and highly efficient compressors are used we invented inverter technology ROFLMakes no difference at all on max power to have an inverter.The only real difference is that it runs slower at lower capacity while a normal airconditioner turns the compressor on and off.Forcing the use of highly efficient compressor technologies and replacing our old style systems would have made a real difference on the overall electricity use.We "save" electricity with LED lights and only turn them on if we really need them.Still the 5 or 7kW airconditioner runs all summer long and in the winter it heats the house and uses even more electricity.Makes you wonder, doesn't it? ;)

Repulsine - the great mystery...

Even before the repulsine saw some attention during WW2 there were sightings of what we know call the classic UFO shape.Be it in Austria, Poland or other places in Europe, people reported weird disk like thing with a dome flying around.What leaked in images and documents after the war shoed that the repulsine looked basically identical to what people saw as a UFO in the sky over big parts of Europe.Then again, the repulsine appearently never made it a usable stage, same for most jet fighters at the time and still they flew around...If we now just take it for granted that actual test flights really happened back then you might wonder why we did not see any after the war anymore.For most critics it is a simple sign of facts and "confirms" that the replusine might have been a nice idea but never anything that really left the ground.As said, I often like to dig deeper and in this case the digging took far more years than what I planned on.I can not provide any solid proof for the following but I am sure even a sceptic will come to similar conclusions after reading it.Try to find some "eye witness" reports from people who saw the so called "Roswell UFO".Yes the one that made Area51 so secret and famous...Reports can be boiled down to some essential features of the hull, for those who saw it proof that it is alien.Three distinct round shpes on the underside, like you add the bottom of an egg to a round disk.Said disc of the bottom was also shaped like a wing, or the flying disk toys our kids like to play with.On the other side the shape grew up like a half shphere with an added cone or round top on it.On these area they claimed to have see engine outlets or similar and appearently the top cone was spinning in another direction than the rest of the UFO.Now I am no expert for Roswell but if I leave area and time out then I could have been fooled to think these people discribed exactly the same thing people saw a few year eariel flying over Europe.The Roswell UFO was not from another world, just stolen from the looser of a really bad war.What was seen was a working Repulsine, be it an original or something the US created from the 5 prototypes that disappeared after the war.Ha, ha, good one, then why don't we saw them flying after this anymore?Well, for starters it was a testflight gone wrong.Presumable it was planned to be limited to Area51 but the pilot lost control.Considering the Nazies appearently did their best to kill everyone involved in the project before the aliies arrived it is no big surprise.What that test flight would have shown is the impossible manouvers people already witnessed over Europe.90° or more turns at full speed instead of making a turn like a plane, sudden changes in alitude as well as accelleration on a level that makes even modern rockets blush.And if it really was the first bigger testflight they did it explains the big secrecy about the Roswell incident and what followed and created Area51 as we knew it.A "weapon" capable of these things would mean total dominance and options to impove planes and more.So why did they not even do that - or did they?The repulsine was created based on what we call today fringe- or pseudo- sience.If there is only one peroson, or a few that can even understand the claimed working principles that it can't be science as we know it.So, lets take a look what things were already heavily used in the repulsine that "we" claim to have developed or discovered decades later.Coanda effect.When air travels over a surface then it will follow the surface.You can try this with paper strips and blowing on them as well as a stream of water and some shaped objects.Long known but never found any real use until the military picked it up.For example air inlets were then developed to utilise the coanda effect.Remember how a lot of them these days look like a ducted fan housing?The round and slightly conical shape of the inlet will actually act like an airfoil and provide lift - of pulls forward in the direction of the air flow direction of the engine.I supercars we use it to create more downforce and better aerodynamics.Venturi effect.Again a very old one but funny enough also a major factor to make a jet engine work.Tesla turbine.In the Repulsine the rotating copper disks acted like a huge Tesla turbine by using a similar effect.The space between the disks got smaller and smaller towards the outer perimiter.Due to the fast rotation the molecules were accelerated and this created a partial vacuum.We use these principles today for specail vacuum pumps but also in military applications.Harmonics.Without harmonics and resonance the Repulsine would have been impossible.And at a first glance it seems we never made any use from that bit of the machine.Then why do we design exhaust systems in such a way than already the extractors ensure a pump like action and controlled backflow?The sound a good exhaust makes is also based on using the harmonics created by the explosions in the cylinders and expanding gasses.We learned that it is far more efficient to use harmonics and resonance in an exhaust system from somehwere ;)Plasma.The repulsine was said to have emitted a bright glow during certain movements or speeds.To create plasma we need a lot of energy, not so much however if the plasma is a by-product anyways.We learned that a high enough voltage differencial in a vacuum can create a nice plasma arc.From there things like analog TV monitors were created.But we never made anything that creates plasma for any use in an atmosphere.Well, unless you start to check supersonic rocket engines and other things.The working principle is very, very close here in some applications like the ramjet.Vortex energy.Today we see all vortex energy stuff as a free energy scam or at best a waste of time.But from the inlet to the outlet the entire Repulsine utilised what we now know as vortex energy, vortex math and so on.The air is twisted and spun around so many times that it is hard to keep track - but it always happened in a harmonic and resonant fashion.In some way this is implepemented in very expensive cars to keep the ventilation system almost silent even at full power.If you ever take an expensive car apart you might wonder why the air system is not as smooth and straight as you would have expected to get this silence ;)There is more but the list would become too long ;)So, if the repulsine was really that great then why was it taken apart to only utilise fractions of it in other things?If you have something really great that combines a lot of things then no one would suspect if you "developed or discovered" some of it in other projects.And to give you a very bad comparison for the other way around:If you know how to combine a petrol engine with some long blades then you could fly!I know, we did that already but you get the point.I can give you a motor and blades but that would not mean you could build a plane or even helicopter!At that time and still today something like a Repulsine would upset the "balance of power".If claims are correct then the engines of the repulsine were only required to provide the enrgy for directional changes or speed but it flew on "free energy" as the main engine system.In lame words like a jumbo jet that only needs a small engine for the hydraulics and electricity...Another big problem is the replication even if you would have a complete and working model to disect.You see most parts were brazed or welded as screw or rivets would have been problematic in certain areas.Other parts like the Kudo horn like intake systems would even today pose a challenge if you want to replicate them 100% correct.And if your understanding of science and physics greatly differs from those who originally created the thing...If your understanding tells you a dice has 6 sides (we all know that) but in my understanding it would have 16 then you would never understand how my dice rolls ;)Bringing true free energy of any form into this world is only allowed if someone can still make good money from it.Just check solar cells and wind generators - we all can have them but our providers make sure they have enough of them as well ;)Will we ever see a fully working Repulsine again?Of course !Some people like old cars, some collect old planes or old machines and tools.A great project for people in the right trades is always to build thier own little steam engine.So to say as a reminder of how it all started.Same will happen with the Repulsine as the first really utilised free energy machine the world had.The war and killings were not what really scared the world.This happened and will happen over and over again to various extends.Really scary was once certain people realised what might happen if over there the war would end with a victory and people would have time to develop for peaceful things instead.Without the war or this idiot Hitler a peaceful war would have taken over the world by storm.Those making sure we know nothing else but paying for our fuel and energy would have lost their monoply.Times change though...We destroyed our world with our needs for fossil fuels and electricity.What is left we destroy by chopping it down, digging it out or just by building new estates on prime farm land.People are now more desperate then ever to find ways to reduce their energy bills or enviromental impact.Otherwise Google wouldn't make billions on all the fake free energy videos out there.But what would it take to recreate the Repulsine?The person able to come up with the understanding of at least attempting to build one again would need to have certain qualifications and titles.He or she would hold a Nodel price for completing some of our known laws of physics or for finding some of the still missing ones.It would be a quite hard to understand and like person too, maybe even highly autistic.The person would also have an addiction like need to complete things, add the missing bits.And of course a totallydifferent understanding on how nature and the universe work.David T. from England is such a person, or at least the closest mankind can offer so far.He can see math in his head as shapes and images.Complex math problems appear to him like developing landscapes in high detail.He even learned to speak icelandic fluently within 7 days!!Imagine such a person would develop an interest in the old pioneers like Schuberger, Newman, Tesla and so on?Where we normal people fail to see any relevance or connection a guy like David would be able to literally see how all these inventions and ideas connect.He would be able to SEE the math behind it!Knowing how something was supposed to work and combining what is known through patents, drawing, videos or reports would enable such a person to make conclusions.For example where we might just see a nice pattern when we throw a stone into an undsturbed lake such a person would also already know and see the corresponding math the created the waves and why they were created exactly like this.Assuming David has no real interest in such things, then is it possible others already try?Sadly yes and even worse they do it with kids.Learning methods that are different can bring great results.For example while we use a calculator for big numbers some kids attend really strict and performance based classes to do this with an ancient abacus!After years of hard and often painful training they are able to it with a small abacus that only has a single row of discs.Shortly after they graduate to a virtual abacus - they only twitch their fingers in the same motions they would use on the real thing, but the disks and rods are all just visualised in their heads.That however is all meant as an improvement and the kids do it because they want to and not because they are forced to.Like learning to be a chess champion before even being old enough to work...In china however we have a very selective education program.Kids are not just trained slightly different to our kids but also closely monitored on their progress.As soon as one stands out for some skill it is subject to examination.Being well above average here means it is an opportunity for the kid and the parents - on paper at least.We in the western world would see it as a viscious circle though.Over the years china developed not only a better understanding of how these special kids brains actuall do their things but also how to create tests for this purpose.What looks like impossible or nonsense to most kids will trigger a scecific response and understand in those that are special.We would create something that allows parents to know early on where the kid has really good skills and what activities should be promoted.In china though the parents receive a nicer flat or some additional income while kids are send to a far away school.Again we would refer to such a school more as a boot camp.Discipline is at least on military levels, same is the punishment system.In most cases families are not reunited for many years, phone or even video calls only happen in the rare times when western TV crews are allowed a sneak peak.I just say: If a kid would see the parents often enough then it would not only know what to talk about but also be happy to talk to them - this however you won't see.It is like they talk to some distant uncle or such.What is really scary though is how these kids are trained to see their purpose and how important it is to be the best in what they do.Imagine you lost your kid at an early age and the only thing you got over the year was letters from the government saying how well it is doing and that you can be proud of it.Then it graduates and you are not even allowed to be there on that day...After that the kid is gone for good, you get a new flat and your proud kid supports you with some nice extra income.You don't get to know where it is working, what it is doing or if it might just be attending some university.By any standards these graduated kids can be seen as a great number of genius young people.Math, music, languages, science, you name it and they will have the experts aged below 20 for it.But what do they do once school is finnished and life starts?So far no reporter or family was able to figure it out.Means they don't appear in some high profile company, they don't start a successful business or teach at any public or private school.I leave it up to your imagination where thausands of kids find secret employment once they graduated....If, at least in theory we could be able to understand all these old technologies then why don't we at least try?Everyone has a goal, some desire a happy family and nice house, other need fame or just money to be happy.With that comes greed.You might have a really nice car but that does not mean you would give to some neighbour for a trip.Even if it just a nice rose garden, you might not want to share the views with anyone.This is true on all levels and we created a term for it "Need to know basis".If you just operate a press in a factory then you don't need to know when or what the next job is that comes for your press.You will know when it arrives and can check the documents attached.You don't need to know that your council is expanding and it is only seen as a courtesy to let you know on some notice board or in the local newspaper.And even our government does the same.What we do from the first days of our new baby we do on all other levels in the same way.What the baby does not need to know we won't tell or show.But we provide all the littly anklebiter needs to develop and be happy.Changing nappies, feeding, proving comfort when sick or having a nightmare.Later we teach language and other skills like walking.It goes on as you know...Humanity as a whole is like a little kid as well.If we would know all the little, dirty secrets then we would riot and go mad.Things that are of no concern are nothing we need to worry about, so we don't get to know them either.Knowing how build the latest fighter jets is seen as a thing that would give a possible enemy an advantage.Makes a lot of sense to everyone as these things might have to protect us one day.The questions that remain are:If humainty is a child, then how old are we now or when do we graduate?If there is a collection of secret and old knowledge then who owns and controls it?What would it take to force the release of all the things people actually created for a better world and not to be locked away?As funny as it might sound but one answer to all these questions would be to do nice orund trip in your Repulsine.Fly over ever single country in this world.Let their guided missle and what not chase you and once enough show then how quickly you can make a 180° turn to get behind them.So called unimportant countries might ignore you and the people only enjoy a nice show.Those powerful enough will fear you and think it was "the other side" showing their superiority.Once done with your round they all will have to realise there is a new power that is at the helm now: Knowledge and understanding.No more secrets, a repulsine for everyone who wants the plans to build one.A new world would start.Ever thought about that when wondering why all these "Aliens" we see in their ships in our skies never land to say hello ? ;)Even if they would be Aliens and not just some human pilot in some experimental craft:Shouldn't this demonstration of absolute power and control without any violence tell us something?The Repulsine need to come back to life to end all this UFO nonsense and Alien theories out there.You hear the sounds, see the ligh show and impossible abilities.And suddenly most if not all UFO sightings would have a common factor again.Just because the Repulsine is claimed to be lost and that it never actually worked despite film evidence showing the opposite does not mean there is no one using the technology.A working Repulsine available to everyone would also kill the doubt on so many other old inventors and "fringe" scientists.Science and physics would need to be redifined as would be able to find a lot of missing links.I know there is not only a lot of people out there trying to get what they can about the Repulsine but also that there are others who try to prevent this.You have a really easy time getting permission examine some old and histrically important artefact from a museum than getting just a hands on approch for what remains of the Repulsine in various places.Not even decent 3D scans will be allowed.Anything like just getting a tiny pipe cam inside is rejected with the excuse it could cause damage.If the thing is a hoax and never worked then why would it be so important to never touch or move it? ;)I recently got word that two of the remaining Repulsine "artefacts" were examined by the same group of "scientists".This happened in the late 80's and said scientists were claimed to have had acces to a collection of spare parts for the original Repulsine that was lost after the war.A private collector was also mentioned who denied all access but what he had in a secure storage facility appearently disappeared shortly after his refusal.Putting all the dots and hints together it would mean that someone in the late 80's was able to get literally everything that is left of the project in his hands.Those who claimed to have seen these scientists working on the Repulsine leftovers claim they used top notch technology to do so, including 3D scanners - and those were basically imossible to get back then for any uni out there...The laptops used were said to use touchscreens and were connected to all sorts of equippment.And they did it in almost total silence, like a group who studied a performance many times and knew exactly what do when and where without the need of many words.Professional in examining something unknown all all possible levels.I was unable to get any information on these scientist or who they worked for.But if you are one of them and readin this then I would love to hear from you!

The Moon - What do we really know and what is possible?

If we look up then seeing the moon is the most normal thing to us there is in the sky.But did you ever wonder how it actually got there? ;)Theories are out there by the lot, including those from real scientists.One of the most common is that it all started by catching the thing and that all was perfect at the time.Over time the orbit then stabilized.Other theories include that formed when our planet formed..What they all lack is what is common and true for all other moond out there: These rotate.According to science an object the size of our moon would need to rotate to maintain a stable orbit.No one told this to our moon, so it just stays in a stable orbit anyway.The only other accepted theory, that funny enough never mentioned OUR moon, is that the center of mass must be facing the orbiting planet.Now theories can run and wild if you let schientifically people loose on a subject.Official NASA data obtained by monitoring equippment on the moon supports the theory of the center of gravity.You see, sesmometers recorded "moon quakes" but also the impact of burnt rocket stages - the later were dropped on purpose.At first everyone agreed the equippment must be faulty but going through it again and again confirmed all works fine.So what got them so exited that was never officially made public?You see, every thing with suffient mass will create a sesmic shock on impact.On earth we can located the source of an earthquake or even explosion quite accurately.Same happened on the moon only with one difference to earth.Every impact caused a ringing effect.Like a bell, the soundwaves and shockwaves traveled through the moon for very long times.An early explanation was that the moon is made from really hard rock or that it might even have a metal core.This was rendered useless once the actual mass was calculated and it turned out the moon would rip us apart while spinning around us.The term "hollow moon" was born.Another interesting thing happens when you try to track down what equippment was left on the moon during which specific mission.Everything up there must have been installed at some stage.For some things though it seems there is no record when or where exactly something was left up there.Then there is the thing with the interviews...If you check the fuzz about the first moon landing then back then you couldn't help yourself but got exited as well.None of the three astronauts however appeared to be at least a little bit exited about going where no man has gone before.Somehow like visiting Iceland for the first time only to realise someone was there before you already.But it was the moon, not some easy to reach island...And while up there we did not see any exitement either, like fully staged and planned ahead.Like a not so 100% school rehersal.Claims that it was a fake and actually filmed in some studio have been verified to be false - they really were up there.After they came back two went silent and refused any interviews about the moon.All three though never spoke about anything we did not see on "live TV"...All the missing segments, the drop outs, the silence during communications...The money...Apart from the Pentagon making a disappearing act of 6Billion US, the already planned and staged moon missions were cancelled with no valid reason at all.One mission already ready to go to the launch pad, crew fully trained and briefed.Two more ready for final assembly.Official reason back then was "We have been there, it is time to explore new things."Almost the same statement was made by Obama a few weeks after he claimed "We will go up there again!".If you take away the costs for the abandoned missions then the money blown up to the moon has a huge difference to what can be tracked back.The lost sum equals out to about 8 more moon missions plus tons of state of the art equippment (back at the time it was state of the art).If you add what the Pentagon lost we are close to 15 more missions.The now...A few years back a lot of previously declared top secret documents have been released to the public.What was a good idea however turned out to be a bit too much.Quite a few documents were included that provide missing links to "incidents, missions, money spent"...Within these piles were documents indicating that space missions of the same extend as the much later moon missions were made.Same rockets, similar crafts, same requirements for water, food and oxygen, some though with just payloads of oxygen and water.Mind you though the documents speak from proposed options and not planned missions.And none of them had any exploration within it, just deliveries if you don't mind the comparison.Those documents about the ringing of the moon and how this would impact on the things we assumed to know about the moon were in there as well.What is really interesting though is what came back from the moon.None of it actually indicate that there is suffient ressources up there to justify mining.Funny enough exactly is planned on a military style.Seems fair enough considering the military can provide the best people for such a hard job.Some normal miner might have no problems getting under ground every day but knowing he is on the moon and might never make it back is another.With all the probing done that we know of you would assume the planned mining operations would be in an area rich in minerals, metals or at least something to generate fuel or oxygen.But no, it is planned to happen "on the dark side" and in an area that appearently was never explored in other ways then taking a few blurry pics while flying around the moon.However, both Russia and China claim to have been very close to this area long before details about the mining became public.And that brings us back to the past and what astromauts stated or to be precise refused to confirm or deny.In some videos we can see movements in the background.In several adio stream we hear the comments to what happens in the videos.If there is light moving around then it does not matter that is blue.You just wonder what it is and where it might have come from.Imagine the surprise if then in other videos you hear things like that the lights are back or that steam comes out of the moon like a gysir.There were official explanations for the first sightings made by the normal people when watching those videos on the NASA websites.Soon after the videos disappeared from the servers.Copies were made by the curious and quite a few videos were identified later to have contained "sightings" as well.Some even show what appears to flying machines with great manouverbilities.And if you take the high point of the happenings then it is also the same time when it was decided that we actually have no real interest in the moon.Astromauts later denied to have ever made any comments like that they are being followed or "escorted" by another craft.And the same Astromauts many years later still refuse to deny or confirm that what we could see and hear during their mission videos actually happened.Don't get me wrong but if the deny it then it just means we all saw some refections or such things.If the confirm it then we know something was out there with them.Doing neither usually means what we saw is ture enough to deny any knowledge about more details.Why then the sudden interest?Trump wants to get up there, military mining, private companies not to forget China.If there is nothing at all up there then why would they all spent money that could provide a much better living for those with low incomes?Even if it would be just for new schools and hospitals the money would be better spent if we trust the official claims about what is up there.The not so official claims....We already know NASA does not want to come with an official explanation why the moon sounds and reacts as if it would be hollow.Same for any video, audio or picture evidence indication there is sturctures on the moon or activities.Here is some of things that other people of great knowledge and with nice degrees under the belt say could, might or even is true about the moon.1. We have no evidence that the moon was always there, only what we have in record throughout history.Some claim the moon would be an artificially created structure.Indications of techonlogically highly advanced civilisations before us are there.And mining out a tiny planet and placing it in earths orbit is not far fetched if you consider higher technology levels than what we currently (officially) have.2. The satellite claim.Like the Death Star our moon could be an artifical satellite placed there for a purpose.What speaks for that theory is the impact craters on the moon.If it was never spinning or better rotating around all axis then a lot them would have been impossible.A crater always shows to some extend the direction of the impact.And on the moon they all apear to be direct and straight hits only.And even at some proper angle that against physics did not create a corresponding crater: Our plant would have been in the way.Officially it is claimed though that there would not be much of a directional crater because of the missing atmosphere and all debris settling evenly.Debris however does not explain the deformation from an impact at an angle.The satellite claim would also explain the missing depth in the craters.By the size of the bigger ones the crater should be much deeper and as said show some direction.If however the rocky surface landed there over time or is just the remaining natural hull then the craters could no go deeper.No advanced civilisation would design a stationary satellite that get a hole as soon as some big space rock hits it...3. Undocumented missions.If claims are true then we have been up there a lot more times than what our history lessons tell us.Tiny probes to analyse things, send data and so on are a thing not the the USA did.If you explain the reason for collecting seismic data by wanting to document an impact of an astroid then it is a joke.Sure it would be possible but what could we learn from the data?Nothing unless you consider that in some unoffial missions drilling was attempted on the moon.Sample collection to evaluate what is in the ground of use for future missions.Some documents now claim that all these attempts ended prematurely.Drills failed or broke, drill heads failed to go deeper and upon inspection were totally worn out.And all seemed to have happend at around the same depth.Although there is no atmosphere on the moon - if you stand on it you would be able to feel vibrations of the surface.Something astronauts would have felt during the drilling.And you can feel the difference between a vibration ending by stoping the drill and one that keeps going for a long time after...The dark side is visible in quite a few school books.Looks like the front with the brightness corrected just with different craters.Ever bothered to scan these pictures in and use some software to find matches to craters on the front of the moon ? ;)Anyways, those images show us the moon as near perfect sphere.What they don't show is how the images were actually made.They certainly did not use massive search lights from orbit to provide light for cameras.Means other sources were used, like IR, Radar, Microwaves and so on.Like we found the ruins of old civilisations by using satellites that can "see" through the forest and soil.And with that it would certainly be impossible to create such a nice and detailed image like we get from the front side.If some is edited, then why not all of it...And if all those missions we don't really know about also landed on the dark side it would explain a lot of things.All sightings seem to have disappeared to the dark side.And all leaked informations about previous missions before our first landing idicate the interest in the dark side was actually huge.They all ended though with one mission report claiming to have spotted lights on the dark side.Moving and stationary and when trying to get a better look by adjusting the orbit for the next round those lights were all gone.But audio recording indicate that from that moment on the astronauts were no longer alone and followed until turning back to earth.Several attempts seem to have been made to land near sightings on the dark side.Those where the astronauts returned home the never were the same again.Documents claim long treatment in mental facilites or suicide.The official missions appearntly started with the backstory of exploring.Some now claim it was attempt for a peaceful presence that still was not tolerated.4. Stories from involved companies.Even if NASA builds a craft themself they still need the corresponding supplies.And for a lot of things they are made outside by independent companies and contractors.Trying to track down early space mission again seems to confirm all claims about previous missions.The amount of materials provided would otherwise mean NASA actually crashed the majority of things right after take off without anyone noticing.5. Launches...So far all claims about previous moon missions or just secret ones were denied.I call this "plausible deniability".In all statements it is refered to the official launch sites.Things like being in public view and so on.What is not that commonly known is that there were a lot of capable launch sites available.After all big rockets have been tested in secrecy since we had the first.The claimed landing of the chinese started a big conundrum.At first the US claimed it never happened because there was no rocket that went up.Images prived by the chinese however clearly indicated the opposite.Not much later it was noticed that a few launches might have been misinterpreted as missle tests....What does that really mean?Quite simple: The surveillance is not perfect if the other side insists that it happened.The plausible deniablity is gone.If the US was "forced" to confrim they actually noticed the launches then it also means the chinese claims about the US doing the same could be true as well.And wasn't it a very important thing during the cold war to know when, where and why the other side launched anything?The silent agreement not to go up there again was broken many times...And although most if not all of these mission ended in orbit only it makes you wonder.What would be big deal even if all claims and conspiracies would be true?A hollow moon would defy what we know about how the universe works.With that it would also contradict some of solid laws of physics.So we need(ed) proof.Assuming we had that for a long time already then it leaves the big question of why it is hollow.Natural or artificial.Nothing natural would make sense so we investigate further.And if people still claim that they can use their little equippment to every now and then hear transmissions from the moon...Sure some things up there transmit data all the time but they do so on common frequencies and not in a range that is and never was used for long distance communications.The interest in the mon came back with our modern technology.We have watches with more computer power than what was used for the old moon missions.Materials and manufacturing methods that provide much safe crafts and space suits with a fraction of the weight of old designs.And we have new means of taking more or less limited energy up with us...We are prepared so to say.No matter what really is up there, no matter if it natural or artificial, just the fact that the moon is hollow changes our views on a lot of things....What do you think would be the best explanation for the data showing the moon rings like a bell?

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....
