I am mad-scientisting (to coin a phrase) a little 12-foot flat-bottom boat. I plan on mounting a pair of 12-volt, 50-pound thrust trolling motors (hooked to 24 volts YEEHAW) , positioned on a transom-mounted frame with a motor at each corner. I will use varying and reversible motor thrust for steering. The reason I am running them from 24 volts is for BRIEF bursts of what I hope will be crazy speeds for an electric-powered boat.
I've already designed, built, and tested a pair of PICAXE-based PWM circuits which will read a POT voltage and shift PWM control to a forward, reverse, or stop sub-routine. The circuit works like a charm with either bipolar or MOSFET controls in both high-side and low-side configurations
My problem is that I haven't been able to find a POT that is anything remotely like what I'm looking for. What I want is a lever-controlled POT with a lever position radius of about 160-170 degrees and some kind of center-stop or center-indent. Normal POT's have roughly 300 degrees or so, and that's not practical for what I want to do. If anyone knows of a source for that kind of control, I'd love to hear about it. I'm not totally against trying to construct my own, but I'm ALMOST totally against it.
