Colin is busy at work with the latest iteration of the CannonBall hardware. He's constructed a bare bone version of CannonBoard using the new board designed, and programmed with the firmware that we prototyped on the previous Arduino setup.
Currently it's a minimal setup, with only the essentially components soldered into place (the CPU, the RS232 level shifting chip, some debugging LEDs, the resistors and capacitors). All looks good so far.
