[Terry] sent in the first of his projects that he’s posted on his site. Having grown up in the midwestern US, I can’t even express how badly I wanted to build one of these puppies when I was a kid. His remote control lawnmower is essentially the bastard child of a three way between a R/C car, a wheelchair and the lawnmower. The radio is interfaced with the control box from a wheelchair, otherwise it’s a good welding project.

Nice work. I’ve one suggestion – a safety circuit that disables the mower if radio control is lost. There are a few devices designed just for R/C projects that’ll do the trick. (Update: ok, there’s a failsafe in the design but I wouldn’t call it optional!)
