Hello all, The school year's starting and I need to commence my annual science project. I wanted a good RC car to hack. The LEGOs aren't sufficient. I don't need speed at all, actually I'd rather it be slow but I can always gear it down. But I would (...) (25 years ago, 6-Sep-99, to lugnet.robotics.handyboard)
