I decided to build my own Midi Fighter, a MIDI controller that uses arcade push buttons and has RGB LEDs for a light show. Powered by an ATmega32u4 and runs on Arduino libraries. Works with GarageBand, Ableton Live, Traktor, etc. Full build log here: https://medium.com/@monkeytypewritr/building-your-own-midi-fighter-406948137f8f

SANWA OBSC 24mm Push Button
Clear body with black plunger
I really want to build one of these but I'm not sure about the ATmega32u4, I'm not sure if I have the skill to hand-solder a QFP chip.
