My cheaper attempt at building an FLD for my R2D2.
I'm trying to build my artoo as cheap as I can without spoiling it too much. so I thought rather than go for the normal 5 x 9 matrix, I would build my own 3 x 6 matrix running from the max7219 and an arduino. This way I can run both FLDs off 1 max7219.
probably not saving massive amounts of money to be fair, but every bit helps I guess :)
