Ok, not really furry at all, but this thing has taken up so much of my time lately. If you're a perfectionist, PCB layouts are never finished. I doubt this one ever will be!

This board will be part of an unmanned ground vehicle that I've been building at home. It accepts commands from an industrial computer over RS232 and controls two motor speed controllers that drive the motors, which in turn drive the tracks. The RS232 protocol is binary: synchronisation word, left speed, right speed and a checksum. There's a header on the left that will be used to add feedback from quadrature encoders at a later date.

This board is also an experiment in home PCB fabrication using lasers. I've prepared a copper clad board with a layer of etch resist and jencen is going to try and ablate that with lasers! After that, it's a quick dip an acid bath and the result should be a PCB :3
