Treadmill Motor Controller Answered

HI, I would like to make a very simple controller my treadmill's Motor. Its MoBo went bad and I dont wanna fork over $200 for a new one. The motor works fine. I just want to make a very basic DC Motor speed controller. I know just a simple Pot or other variable resistor wont do.Will it? I've been messing around with Electronics since I was 9 so I'm not afraid to solder up some circuits even if its a complicated one. Im looking to spend around $50. Thanks.

you use a triac you could use a 555 timer driving a triac, using pulse with mudulation. Use a pot on the 555 timer for variable speed.
