I'm using this as a music and speaker controller for Music Assistant and Home Assistant. If you are interested in the esp32 yaml code, message me. This was a print project I made before I had my first 3d printer, I borrowed use of a printer in my office. More recently I bought a Bambu Labs P1S and refined it. I've been printing this more often as controllers for a sunrise alarm clock. I'm sure I'll find other purposes. These are neat little circular knob and touch enabled devices.
