Shepherding electrons

I've had a MicroPython board sitting around my work bench for a while.  I think it's a brilliant way of interfacing hardware and using Python in a very straightforward way.  I've thinking about getting into into programming ARM chips for a little bit, and my MicroPython board came to mind.  After all, it's potentially a great development board if only we could hack the firmware that comes with it!

I can now control my quadcopter with a PS2 controller - really cool!  The magic control box is powered either from the Arduino Nano inside and communicates with the quadcopter via radio, or a lipo battery, which is rechargeable over USB.  LEDs on the top feedback about the drone status and look really awesome. UPDATE: I have now incorporated the control electronics, and a long distance radio module directly into the PS2 controller!
