This section gives some basic electronics and robotics information along with helpful links. I also detail a lot of my projects. For most of them I've included schematics. I use ExpressSCH for drawing them and ExpressPCB for designing circuit boards. They are a free package from expresspcb.com. You can download for free and get your boards professionally manufactured for very reasonable prices. Of course, with the final layout you can also etch your own boards at home if you choose.

This project was from David Cook's "Robot Building for Beginners". You should check out his site at www.robotroom.com. He has a ton of great information and has written two books that take you from a complete novice through building advanced robots with microcontrollers and even aspects of machining parts. After some playing around with BEAM robotics, this was my first real robotics project. It's a line following robot that uses CdS photocells and an LM393 comparator chip to sense brightness changes on a surface. The robot can be switched to follow a light line on a dark surface or vice versa. It was a fun project and Dave's book details everything from start to finish from prototyping on a breadboard to troubleshooting the final product. Here are some pictures of mine:
