Check out this cool little hack, it’s an open-source motor controller for an electric bike. There’s no pictures of a finished version but can’t wait to see this circuit in action!

n brief the PicOx is a PicAxe 08M based digital Controller that performs an ADC of a Hall-effect throttle and an ADC of a Hall-based current sensor. These two parameters determine the “Mark” value of a 15Khz PWM signal that does the switching to the Output stage. At the end of the project the Controller can sustain 48V @ 75 Amps repeatedly for approx 5 second bursts and is really only limited by the In-Line breaker that cuts the supply voltage, though the entire system’s overall design objective is met reliably at 48V 50Amp operation…
