A device that uses the resonating frequencies of a stepper motor as a
tone generator. These particular motors produce a rich tonal spectrum
that reminds people of obsolete plotters and cheap printers. The buttons
on the front panel control motor speed / frequency, rotating direction
and an ON/OFF switch. Next to this the device has a built in
amplifcation system, which can be connected to an external sound system.
