hello, I have been working on a project off and on for several months and thought I would share my progress. The idea is basically a battlebot with everyday usefulness. A metal frame with 2 wheelchair motors powered by a car battery, with a lawnmower attached to it. I know this has been done before, but I just wanted to try it myself. here is a web page that I made to track the project: http://rediculouslygoodlooking.com/site/lawnmower.html I have specifically been focusing on the H-bridge motor driver, building it from P/N channel mosfets and the code to translate a PPM servo signal from a typical R/C reciever into a PWM value that can drive the H-bridge. I will post some eagle files of the H-bridge if anyone is interested. Also, I am interested in coming up with a good PCB design for a high powered H-bridge (around 25amp or higher at 12v), so if anyone has any suggestions to the circuits I have already come up with, please feel free to suggest changes.
