    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:

    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.
