We’ve covered a lot of floppy drive music here on Giz recently but if you’ve got a few floppy drives lying around (presuming you’re not using them for archiving your old media), it’s possible to hook them up to a normal keyboard for your own drive tunes.
The Moppy project uses a Arduino hooked up to a floppy drive on one end, and a normal keyboard at the other. Technically, it doesn’t have to be a keyboard, but honestly, once you’re making sweet floppy music, is it really worthwhile using some other kind of interface? [Moppy via Hack A Day]
