Basic 74AC240 Bicore
Here he is, after three hours of soldering. His brain is the exact one from the "Junkbots, Bugbots, and Bots on Wheels" book. He's still a work in progress, and I still want to add some indicator LEDs and some solar cells so he can charge a battery. Also, I'm really new to this stuff, and I would appreciate any tips and/or constructive criticism and/or ideas. His body was from a kit called a brush bot that I modded a little with a dremel tool.
