BTTF Nikes with Mattel Hoverboard.

[Emeldahay]

I`ve ordered some Neodymium Magnets. The strong babies - N50 - I got a couple N36s - they are small and already shockingly strong.

My intention ...and I`ve no idea if this will work - is to fit magnets to the bottom of the board inside the resin hover plates. Then try to repel the board from a custom base that houses more of the same magnets. I`ll be holding the board down with something like fishing line - the theory is cause it cant go anywhere it will settle above the magnets.

I fear it might wobble like crazy - but I`m going t give it a go. I also fear it wont work at all but at least I`ll know.... :love

I`ve actually just ordered two large magnets just now to suss out how much they repel and how many I need.... at £40 each I dont want to over do it. It will be a week before the magnets arrive.


Heres pics of what I`ll be modding - I`m hoping it can take the weight of the Nikes as well but thats no crucial. I`d be happy with just the board hovering without Nikes if thats all I can make float - As long as I can prod it from time to time and see it bob about. :lol If this works I`ll upgrade the shoes if the nike project works out. :thumbsup

NOTE THESE ARE NOT TRULY HOVERING - I just put the stand in a good position.

Just dont ask me "why?"

Now that's pretty cool.

I have visions of this shooting through your window.

Just make sure you keep it away from your TV

I have a feeling the board will just want to flip over to adjust itself to the opposite polarity, or it may just push it off to the side. Try some small magnets on a peice of string, you will see what I mean.

Thats what I`m hoping for - It will only work if I can tether it down so it doesnt flip.

My worry is whether or not it will settle or will continually try to adjust itself the same way the magnets on string behave - How I tether it is key....erm...I think, :lol

 

[androidandy]

I am sure it can be done but I hope that it doesn't end up defeating the idea of it looking like no stand. You should try to make some miniature models to work out the concept.

 

[Emeldahay]

Good idea - I`ll test it out with the magnets that are coming before my board is destroyed.

FYI - The tether/s will be pretty subtle - fishing wire or magicians wire or similar.

 

[Hitogiri]

Cool project. Now if you get it to hover.....well lets just say your pm box would be full quick. lol.

I can tell you now, that won't work. The key behind magnetic levitation is the switching polarity of the poles. The top toy, which shows the floating is also constructed in that way, two halfes inside the top of a N/S magnet facing an bigger but weaker magnet with either just N or just S pole - you spin the top and the high rotational speed compensates the pull of the weaker magnet.

Same goes for the Transrapid magnetic leviatiton train - the rails have controlled inductive magnets switching the polarity within milliseconds.

Or you can wait till the Austrian physicist Dr. Martin Tajmar have the comfirmation from other collegues in the world, that he created recently an antigravition device with a superconducting stator, which generates the Thirring-Lense-Effect in a way much larger scale.

just so you know I`m not trying to create a real one. People are working on them but they wont be ready till 2015. :rolleyes

I have no intention of free riding this board.

This morning I can get a magnet to hover inside a carboard tube - you can push it with your finger and it bobs up and down - you push it hard it springs way back - that very easy to do cause the magnet cant flip over - I thought that would be the case but I hadnt checked till now...I`m glad its ok.

If I use all my fingerly force the small magnet wont get more than a inch closer to the base magnet - when it bobs back it settles about two inches maybe two and a half from the base magnet. I`m getting much more powerfull and larger magnets to give this a chance of working. I`d say the chance of taking the weight is good - the chances of holding the board in place slightly less than good.

If I can find a correctly sized clear plastic tube I`ll take a photo - my intention is to figure out a way of harnessing the board down so it doesnt flip...and also so the fibres holding the board down are as invisible as possible...as someone mentioned earlier not much point if the harness is more visible than a well positioned stand.

Its much simpler (and a lot more fake) than the Tajmarlensethrirringgravitomagnetismwikipedialevitationlock that you mention.

 

[Hitogiri]

LOL C'mon Emeldahay you know you wanna ride it atleast once hahaha. Where'd ya get the shoes? I didn't even know they really made those...

 

[Emeldahay]

If it can take my weight I`ll give it a go. but I`ll be lucky if it takes the weight of empty shoes.

The boots were bought from a member here...not sure where he got them. If the NIKE build thread come through there will be some available.

 

[Trooper_trent]

I can see how this could work, I used to have a little toy I bought at the science museum. It was a wooden base with a wooden dowel rod sticking up out of it. There were a few different magnets that were rings. If you dropped two of them on the dowel with their poles reversed, the top one would float above the bottom one. The Rod, kept the top one from flipping. SO what if you did something similar out of plexi glass? excuse the crude drawing. It would be a plexiglass tab fixed to the side of the board that would stand out from the side. It would have a square eyelet hole. Build the magnetic base with a square plexiglass rod coming up. Thread the tab down over the rod, the rod keeps it steady and from flipping over and the fact that its square keeps the board from rotating off the magnets. Of course, now that I think about it, it wouldn't be any different visually than having the thing balanced on a plexiglass stand of similar design. The only added bonus would be playing with it, pushin it down and watching it bounce back up.

You could possibly do it with fishing line, but youd have to secure it from every direction , much like a thanksgiving parade balloon, or its gonna launch one way or the other. But if you get too many strands of line holding it down, it will look like a scene from Darby O'Gill and the little people.
Could work though

:lol Yeah, but ain't it very promising, that actually we are soo close to a real antigravity hoverboard?
Now if only we could minituarize the device and cram it under a board...

Have you taken a look at

?

If you just put some pyrolitic carbon and N50 Neodyium under them - ok, maybe it won't float 20-30 cm above the ground, but floats

 

[Grouch]

great idea but it's not going to work.

nice hoverboard too. 123bttf make it? I have one of his and i love it.

 

[Emeldahay]

Yeah its a 123 board...I think...got it from ebay...IIRC that was part of his ebay name.

Its nice.

Still waiting for the magnets - added some more to the order as it hadnt shipped when I called them.

FLOAT DAMN YOU, FLOAT....

Worse case I end up with lots of magnets to play with...
