In the early days of computers, operators noticed that an AM radio set next to a computer would pick up signals from the circuitry. It wasn’t long before someone managed to make one sing by writing a program that made the circuitry buzz-out different notes. The same trick was used on hardware in the 60s, when line printers began to sing. (Probably only when the boss was gone.)

This project, though … well,, what better use for old floppy drives?

Phantom of the Floppera or How to made floppy drives sing Test run of (d)iskette (O)rgan doing Toccata & Fugue ….. Features two 3 1/2″ drives and two 5 1/4″ drives connected to a PIC18f14k50 microcontroller. It interfaces to any MIDI source via MIDI over USB. Straight MIDI would also be possible with an additional small circuit and some minor firmware changes. This initial version can respond to all 128 MIDI notes, and pitch bends +/- 2 semitones. As it can produce only four simultaneous notes, an … Read More
