This is the first of many videos I’ll be posting of my stepper motors playing music. The data for the music is taken from a MIDI file I made. The code for interpreting the data and moving the motors was written by me over the course of a few days.
The sound you’re hearing is coming entirely from the motors. The motors are screwed into some pieces of aluminum from an old project to help them resonate. I’m taking requests for other songs to play.
Currently, the information for the song is stored on the Arduino. Plans for implementing a realtime MIDI stream are underway. Eventually I’ll be able to plug in a keyboard and play the motors as though I were playing piano.
These motors (and their L-shaped aluminum bracket mounts) were taken from The Pipe Dream MIDI Robot that I built in 2008 (see my other videos). I reluctantly disassembled that machine when I moved out of my old house.
