Here's the first video from the field of the new BOB PID Servo Controller running a motor (a tiny motor) from an encoder (a standard low resolution HEDs optical encoder). Not terribly impressive as motors and encoders go, but it's nice to see it out there working for other people. The BOB PID Servo controller is a very (very) low cost, controller. It takes a standard Phase A/B Quadrature Encoder signal telling it where the motor or output shaft currently IS... and it accepts standard step / direction signals from any motion controller telling it where you want it to be... then it puts out direction and PWM drive for a motor driver to make the motor move to the desired position.
