- IMPROVE: reduce size of jack holes to make a snugger fit with less wobble? - IMPROVE: Some nice panel graphics!

- DONE: FIX: Replace the voltage regulator with one that will actually be able to deliver enough amps to power the screen and Teensy facepalm - ~~Can work around this for the moment by connecting directly to 5v Eurorack power with eg Dupont cables~~ - FIX: Fix/bridge/remove power diode that prevents power from USB going…
