Another spin

A project log for Motor as Encoder

Inspired by the attempts of other people around the Interwebs, I use a motor as a rotary encoder, but with a different approach.

I tried this motor (salvaged from a floppy drive):

It almost worked. Tuning was a nightmare. Measurements were noisy, and levels were almost indistinguishable. It jumped back and forth, sometimes started to rotate indefinitely. For a few steps, it worked, but wasn't as nice or reliable as the HDD motor.
