Here is another cool idea for your old hard drives. The device is called a Springverb, it’s a Hard Drive Spring Speaker. There are lots more of sound clips and videos on the site.

Video after the jump.

“Inspired by the wealth of hard-drive recycling ideas on hacked-gadgets and the >springverb research posted at Electronic Peasant. When looking at both these pages… this hack becomes pretty obvious. It helps that i had all the materials laying around already.

One drive was bolted to a metal plate and the plate bolted to a heavy vice. The vice was bolted to a piece of wood. The other drive is just held in place with a smaller vice. as can be seen in the first picture at top, the circuit board was removed from the drive and 2 connectors on the back are connected via alligator-clips to the speaker output of a normal stereo amplifier.

It took a bit of searching to find which pins were actually connected to the voice-coil. I used an amp which has electronic circuit-breaker protection on the speaker outputs just in case… this would be recommended so as not to accidentally blow a fuse, or worse, wreck the amp.”

Thanks Brian.
