Spiderwheels: I have so much to learn...

I realize this is my first robotics project and I should stick to wire nuts and breadboards but I want to learn as much as I can from this project. Frustratingly enough, this means I must take several steps back and pursue PCB fabrication. I built a mill and am getting close to being able to mill boards. The next step is learning how to design them. This is a very overwhelming subject for me and it is hard to know where to start. I have decided to go with Eagle as my layout editor mainly because the RepRap team uses it and this is all I have to go on when it comes to board fabrication. So, I guess the first step is to follow some tutorials. I have chosen this tutorial because it will also serve as an introduction to the FT232RL chip, which is used in the Arduino. Time to learn.
