The motors are top quality, but how the heck do you drive them without shelling out a fortune? Lightweight, with Ramsey Super Stepper! Build an accurate positions XY controller, plotter or even a robot! Super Stepper will drive almost any stepper from 5 to 15 volts. You will be able to control direction, speed, step [...]

This controller was designed to control AC motors with carbon brushes, anything from drills to vacuum cleaners to saws. Unlike normal dimmers there is a phase-cut only once per period. The moment of cutting determines the speed, which can be adjusted from 5-95%. Thanks to this control, this kit provides high torque even at low [...]

The circuit is not particularly susceptible to motor transients and supports FULL STEPS FORWARD, FULL STEPS REVERSE, ACTIVE HOLD, and POWER OFF aka RELEASED. If the motor does not turn then swap around the leads of ONE of the two coils. To reverse the sense of the EN signal simply rework the circuit around an [...]
