zonker board pictures
Here is the random point board I build. I had help from our local Community College Professor to to the schematic, then used online circuit board layout softwareExpress PCB (FREE), ordered the PC board, and then spent LOTS of time soldering ALL the lED lights. But the kids love it. First is the schematic, then some good pictures of what it looks like. Here are the files to go with the software.
