Converter control board: A capable, user-friendly board with a large clear display, accurate measurements and adjustable current protection; development continues.

Digital PWM speed controller for a brushed motor: It works normally and is neatly assembled, but does not stabilize motor speed and behaves poorly with switching power supplies.
