Speed PCB Painting using FreePCB (Part 1 of 2) 

6 hours of PCB routing, designing a double h-bridge (motor controller) for use in a bipolar stepper motor controller. Speed up 100 times. I used FreePCB. You can download it from www.freepcb.com.

The h-bridges uses only N-channel MOSFETS and is controlled with PWM so I can create a chopper stepper driver. I will use an arduino to control the h-bridges.
