There’s a whole bunch of people on YouTube recording cover songs using floppy disc drives.
YouTube user MrSolidSnake745 used stepper motors in eight floppy drives to do a cover of “Pachelbel’s Canon in D”. The video was uploaded in December.
In an FAQ, MrSolidSnake745 explained his process, which uses code written by YouTube user Sammy1Am:
“What this code does is convert a MIDI file into serial data packets and sends them over to my Arduino Duemilanove… The Arduino receives them and then sends the appropriate channel/floppy drive the information.”
Here’s some videos from other users:
