If you’re a DJ or a wannabe DJ, you’ll want a turntable that sets you apart from the rest. You could spend some real money to get yourself a decent set-up or you can make your own if you have an old hard drive laying around. That’s what a group of students at universities in the UK, Austria, and New Zealand did.

They all worked together to come up with a digital DJ interface, and the HDD-turntable you see above sits at the center. The students fell in love with the weight of the disk and the quality of its bearings. All you need are “a few op amps, resistors and a programmable microcontroller of some kind” and you can be mixing like they do. Hit the link for instructions.
