Self Destructing Harddrives

^those electromagnet isnt powerful enough to get pass the metal shielding of the harddisk. =P

Build a EM pulse generator.  Something like this with enough power will destroy the computer plus the neighbors as an added befit.  Anything in it effective radius will have damage.  People might look at you strange when they see 1.3u/100KV capacitors hanging around your room though (14”L x 11”W x 25”H and weigh 220 pounds). -- You do not have to build them this big, a gigawatt pulse would be a bit over kill.

If the hard drive is inside the EM field coil itself, it can crush it. 


Google EM pulse generator to get some ideas.
Watch a few youtubes where a large EMP pulse can killed the electronics in a car within 50' of the generator.  The EM field is strong enough to reach though the cars metal shell.

meh, coils from relays laid flat on the hdd will be enough to wipe the disk imho.

set it up like this:

bork:
Whats the fun in that?

Unless you have smoke, metal flying, sparks shooting out - its just boring.  Massive overkill give that feeling of satisfaction of a job well done.

kitamesume:
its not supposedly fun, you're frying your 100$ hdd with its oh-so-precious contents because some police "might've" suspected something fishy with your drives. with a magnet tho you could still re-use the hdd if you don't end up frying the components =P well the hdd platter's contents are magnetically erasable.
