With the many older desktop PCs getting thrown out across campus, I took it upon myself to make the floppy drives still fulfill a purpose, as my personal MIDI devices with Arduino Floppy Drive Music. My work is based on the guide from Analogue-Chick over at Instructables.
My playlist of music is here. I originally had six drives, but only four sets of cables to work with. However, I am not up to eight drives for the maximum that the single Arduino can support.
