Boards showed up today! Wrapping coils! Testing!

I abandoned the plastic mockup and have the coils wound. Continuity and wiring pattern seems good. None of the components are installed on the back of the board yet, so I'm using the three pin "alternate motor" header as in input to do testing.

The rotor moves a little bit with manual voltage pulses, but the small brushless motor driver I tested with can't get the rotor to turn. There is a lot of room for testing and optimization. Gaps, flux density, coil and magnet coils... guaranteed learning of one kind or another awaits me.

I'll resume tomorrow evening...
