Found these things on YouTube, an odd desktop gadget.

Im trying not to say, "what a load of balls", but that might not be appropriate. :LOL:

I kinda like the idea, though I don't think I would pay that much for them.

Playing near your computer with 216 rare-earth magnets? And nobody else sees a slight risk here? Granted, this is NOT the 80's, and we no longer have stacks of floppies around, but still!! <(o.O)>  ZRO

I must admit that had crossed my mind, magnets and computers are a no no in my book.

Haven't they come a long way with magnets, these days they are massively stronger than they used to be.

How?

I found this on the Wikipedia
http://en.wikipedia.org/wiki/Rare-earth_magnet

That's why they cost so much then they are made of alloys of rare earth elements, I didn't know that.

Quote from: wikipediaThe stronger magnetic fields can be hazardous also, and can erase magnetic media such as hard disks and credit cards, and magnetize the shadow masks of CRT type monitors at a significant distance.

Just what I was referring to. :o

You may want to keep them well away from your car key's also. :o

If he's eluding to what I think he is, it involves some of the more modern keys that have theft deterrent technology built-in. Strong magnetic fields may have disastrous effects on some car keys. Of course, I may be wrong here. :)

Don't worry Data, the key's to the Shuttle Tow Mobile are quite safe against most thing's. However, Dave is quite correct as most newer vehicles have Transponder chip's fitted inside the plastic part of the key. Radioactivity, magnetism and, worst of all, infant spit, can kill them stone dead!. ::)

Just a thought, perhaps someone could ping one into Vettel's cockpit, let it roll around (as I doubt there's any ferrous metal's in there) and monkey about with the odd ECU. Just for entertainment purposes of course. :sign-evil-laugh: :driving:

I've bought myself 3 sets of these from Amazon (http://www.amazon.co.uk/s/ref=nb_sb_noss_2?url=search-alias%3Daps&field-keywords=neodymium). Cost about £35 for all 3 sets (3 x 216, 5mm) inc postage.
They come in a range of colours but I'm not sure how hard wearing the colours are. Get nickel if it concerns you.

You will need a credit card size plastic card. Do not use your credit card though; they are magnets. My thumbs hurt after 1 evening of playing (didn't use a card until later). There's loads of cool vids of how to make things, many using 3-8 thousand of the things. Here's one vid of what you can do with with 1 set of 216.
