Hello!

I'm working on a sensorless BLDC motor driver using no microcontrollers, but rather logic circuits.

This project is near completion since i today finally for the back emf sensing to work.

Heres a video of the driver in action: http://www.youtube.com/watch?v=asvH2e7nKRw

This driver is based on a patent by Allan B Plunkett, however i did change a few things since i already had parts i wanned to use.
