Later, I helped a friend disassemble a Tesla model, and the mass of circuit boards inside was overwhelming—until I drew 5 ...

Running a brushed motor in muddy or dusty environments takes a toll on controllers, with both heavy back EMF and high stall currents. This explains one of the challenge in Europe’s Hacky Racer series, ...

Permanent magnet dc motors need a chunky inductor in series with them if they are fed from an SCR (thyristor) based mains power controller. It is (probably!) possible to safely interface an Arduino to ...

Maxon Precision Motor's ESCON 50/5 OEM module is a 4 quadrant Pulse Width Modulated (PWM) servo motor controller that can efficiently control permanent magnet brushed DC motors (PMDC motors) and ...

One of the bigger problems with any CNC machine or 3D printer is the issue of missed steps when moving the toolhead. If a stepper motor misses a step, the entire layer of the print – and every layer ...

After purchasing the Qu4tro electric skateboard and finding the controller wasn’t quite as good as the skateboard, Timo Brinschein decided to build his very own using a little Arduino hardware and ...
