I was surprised how easy it is to make one. Does this fry the hard drive as well? Than it could be pretty usefull. If the feds would come in to bust your door in, it would be a quick way to corrupt your data.

I believe that in most cases (modern computers) only the motherboard would be rendered useless but other components remain in tact from the tests I have currently seen on the internet; So it may not be the best solution in such a situation.

Nice share by the way! Quite an interesting concept, I saw some company online selling these for $50 a piece, what a rip off.
This will surely help some.
