rotary encoder is a bit sloppy. It is missing pulses when rotated too fast. The reason seems to be that the debounce caps don't discharge fast enough. Would be better to use only half of the state transitions probably. We don't have use for the extra resolution.
Next Steps
[ ] bread-board based test with rotary encoder and logic analyzer to find a working capacitor/resistor combination that works with fast rotation speeds
[ ] add a power bank and charging port (Adafruit panel-mount micro USB socket)
