From the project
Turning otamatones into MIDI controlled instruments.
This is a project that takes an otamatone (https://otamatone.com/) and hijacks the control using digital potentiometers and a Teensy running USB MIDI libraries to turn it into a MIDI instrument.
The Controller PCB files currently use optoisolators. This design does not work correctly. I manually replaced the optoisolators with darlington NPN transistors, and that led to everything functioning as intended. I plan to revisit the PCB ocne I've tested the advanced features of the board (such as the servo control for opening the mouths, and the addressable LED lighting for the heads) to avoid…
