My latest project to build a cheap but very powerful DC servo motor controller. It's actually a multi-part project, that is made up of the firmware and the driver circuit. The driver circuit will be a modular design that will allow multiple driver sections to be "bolted" on to the firmware to allow a variety of different load handling capabilities.

This is a new project geared to provide the community with a low-cost PIC based microstepping controller. It will provide Full step, 1/2 step, 1/4 step, and 1/8 stepping modes, plus will be able to drive 3A @ 55V per coil!

This is a adapter board to allow the LMD18200 H-Bridge to be easily used from a breadboard. I designed this so that I can design/test my new servo motor controller.

This is my first step in building a PC controller PCB mill for cutting/drilling circuit boards. It's based on the L297 and L298N stepper driver chipsets
