"Crackers" PICO Midi Controller takes shape

I’m building a partner device for the “PICO Midi CheeseBox”. This gives four rotary controllers with pixel ring feedback displays which you’ll be able to use to control MIDI playback. It’s called the “Crackers PICO Midi controller”. Why? Take a look inside..

The wiring is a bit crazy, but it worked first time. I’ve got a new build technique called “making the design and writing the drivers before I build the device”. You can see the circuit diagram and the Circuit Python code creates controller instances for each of the four inputs.

The controller will be making an appearance in a future HackSpace magazine, when I’m going to be using it to control a Pure Data synthesizer.
