If you like to damage old hardware. It's possible to use floppy drive
stepper motors to make music. To my knowledge the floppy drives that are
at easiest to damage by making music, are old first generation C64
floppy disks, that use a bump, instead of a light barrier. However, it's
possible to remove light barriers.
