A ragtime classic given new life through SCIENCE! The music you hear is being emitted from the streamer discharge on the Tesla coil. This is a demo of the ATtiny2313 MIDI player being used to interrupt a solid state Tesla coil. A MIDI song is played on a computer and MIDI signals are sent to the interrupter with a USB to MIDI interface. The interrupter then decodes the MIDI signal, plays each note, and sends them down a fiber optic link to the Tesla coil. When a note is ON, the coil turns OFF for a very brief amount of time (It runs 95% duty cycle when playing a single note). The frequency the coil is interrupted at corresponds to the frequency of the note being played. The result? Audible music! The MIDI interface allows keyboard players to play music directly on the coil as well!
