OK. The penultimate, or possibly ultimate question:Looking at pic028, you have a bit of white cable to estimate the rpm. Did you just see that cable move momentarily, or did you see it rotate continuously in both directions?
It moved continuously (no stuttering) for as long as I wanted it to be by having the wires in contact with the connection points. By shifting connection points I could make it go the other way. But they moved in different speed. Lets say 80 rpm and 150 rpm. That they moved in different speeds makes me think that there isn't any "low" and "high" connections, changing direction makes the high and low.
