That's not something I am able to do as much anymore, now that hard drives are becoming obsolete.
I had an aluminium frame lying around for many years that had been retired due to a crack. Recently I cut it up and turned it into wind chimes:
The tubes are hung from a right crank. It's important that the holes for the string are exactly 1/4 of the way down, as the standing waves that make the tubes ring have a node at that point.
A few other things that I've done include bending spokes into hooks for clothes-hangers, and grinding a pair of titanium skewers into chopsticks (sadly they are too short to work well).
What creative ways have you come up with for finding new life for old parts?
