If you love MacGiver you will love how I turned old hard drives into speakers for a Hi-fi system.

One of my favorite spot at work is the electronic dumpster, it's a great source for materials or spare parts.

During my last visit to the dumpster of wonders I found :

an old Hi-fi system but no speaker to go with it.

There was also a pile of old hard drives (busted or really old)

electric wires.

My first intention was to use those old hard drives to add real percussion capability to my Musical Floppy Drive system. But during my fiddling to find out what voltage was required to get the reading head arm to move all the way from one side to another I manage to get sound out of the HDD.

And then things got interesting.
