Arc Reactor - Endgame, designed for electronics!

Finally, an easy to build Endgame Arc Reactor with plenty of room for electronics! This particular unit is designed to house a Circuit Playground Express and LiPo battery - no switches, no fiddling, everything pressure-fits. You'll want to glue down the circuitboard to keep it from sliding. The diffuser is printed in WHITE, and it does a good job of distributing the light. I've included a python script to run the lights; it starts red and slowly brings everything to white, and a “tap” on the case resets it.
