BoB's mouth - Custom PCB fabricated and installed

This morning I got the chance to etch, drill, build, test, install, and program the custom PCB that drives the led array for BoB's mouth.  These first couple images are of the board being tested on the bench, before going into the robot.

The leds mount to the back of the board and are spaced to fit in the holes printed into the robot's body.  This meant mounting the board was a simple matter of press fitting the leds into the holes, soldering up power, ground, data, and clock, and adding a few lines of code to the walking program to produce a simple pattern on the array.

The next step is to do *something* with the eyes - what I haven't decided yet, and decide on a name.
