Close, but no cigar
Wow, that has a lot of creative thinking and imagination!
It runs off LNB power, pulling 350mah max, while running.
Took me a while to get to that point.
They do talk about somehow balancing the dish, so it takes minimal energy to move it, even from the limits.
I couldn't quite visualize how they managed, from the drawings.
A serious shortcoming is the main mount bracket at the top of the assembly.
That has to be very rigid and not twist from side to side, nor droop.
It carries the weight of everything, so should be much more robust than shown.
If we were to brainstorm a similar design, I'm sure we could find some good ideas here, but I think we could do better. :up
