So, I note that the Venture ball Screw unit says "40 pulse". Is that referring to a hall sensor output? Can someone link me to some diagrams or technical info on this? Perhaps I don't need to worry about that at all? The electronics driving the whole mess will get feedback from the sun...

Venture Ball Screw. This actuator is 5X as expensive as most of the others I have seen. Is it really that much better? I could spring for this if it is the right tool for the job.

For a picture of a similar machine, google "builditsolar Red Rock Tracker" . The Forum won't let me post the URL for some reason.

I am building a solar tracker. The mechanics are amazingly similar to a C-Band antenna - a pole, an actuator, some electronics, and a big ugly thing that can move around one axis to point at the sky. Only this one receives sun - light, not satel - light. (sorry) Why the hell would anyone...
