We have lift-off!
Here is a short clip of firmware booting. Note that the hardware can be easily "punched out" from the larger dev board.
Reset controller is now being finalized. This is an independent piece of hardware which guarantees that the main unit responds to outside events in some sensible way even if the software crashes, decides what should happen if battery is low, prevents "bricking" of the device in case of firmware update gone wrong etc...
Preliminary Reset Controller specs can be viewed and downloaded here (now updated to version 0.3).
