exploring the fubarino SD

Since the fubarino has so many pins (45 IOs) and there is a lot material out to grab data from cartridges with an arduino, it should make a good controller for this. I created a cartridge board to get to the headers and this time I didn't want to order and wait for 3 boards because I'm in the mood for etching boards. 

I made those duo LED charlie-plexed matrices a week ago and "ported" my arduino sketch to the MPIDE in order to control them. I only had to swap the pin numbers and it worked like a charm.
