A project from last year, when I heard the BeagleBone Blue could run 8 servos at the same time I got wondering what could be done with all those.

Servos

So I printed some mounting blocks, found a toy glockenspiel and hooked it up to the Beaglebone blue. I had some challenges with the power but built a simple shim to provide power for the servos whilst the Beaglebone provided the control signals. I also had to extend some of the cables.

For the software I was learning NodeJS at the time so that seemed a good way to control the board. A web page sent MQTT messages so a server and a Music Daemon listened for those messages and activated the relavent servos.

The results won't be getting me any concert performances but it was a fun little project to build.
