Hi guys. I am currently out to build a VERY SIMPLE and VERY LIGHT WEIGHT DC motor controller. Currently, I am trying to build a hovercraft for a school project. This hovercraft should be able to go in a straight line, and run off 2 double A batteries. I am sort of loopholing this idea, and running the hovercraft off a capacitor, thus lightening the load.
My circuit, a very simple one, uses a
1: 3 volt DC motor
2: 20F 3.7 volt capacitor
3: simple toggle switch
These parts work, but the problem is the capacitor discharges too fast for my liking, and that the motor vibrates at a high RPM, thus throwing the hovercraft off course. I do not know where to get a bigger capacitor, but I think that the main need is I need a PWM circuit, as simple as possible.
Thank you, iflymyhelishigh
