Hi. My name is Tony. I am brand-spankin-new to the forum and this is my first significant attempt at building a robot from scratch as well as my first post to the forum. I have studied several aspects of design, control and implementation on this website as well as investigated some other resources. I have taught myself the basics of using the Eagle PCB design software and I have preliminary designs drawn up for a simple motor controller and another schematic and board for a very basic and inexpensive augmented main control unit based on the ATmega644P. I would like to make them available here and request that anyone interested take a look at them and offer any comments as to any issues you see or recommendations you would like to share. I hope for some feedback before I try to etch the boards and put them together. I don't know the best way to make them accessible to this forum, so if anyone would like to help walk me through the process, I will be most grateful. Oh, yeah, To complicate matters, I am working from a MAC computer...FYI. Thanks. TONY
