The printed circuit boards for two DingBot units. Made by Advanced Circuits, and I think the quality’s great. Their standard prototype package doesn’t include solder mask or silk screen, but that’s fine for these prototypes. It also doesn’t include interior routing, but a few quick passes with the Dremel took out the corner bites and enlarged some of the holes I had goofed up.

Looking forward to getting these assembled and in their boxes!

The battery-powered DingBot. The main reason for using batteries instead of AC at the moment is just that I’m short of 3V regulators. But, it does feel nice in the hand.
