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 swit

The first motor turned out have too little power to give the rotor enough speed. So I added another motor and a gear, and put stream line wings on the LED bar. The first motor had the rotary encoder at
