I seriously doubt anyone here will do the linked arduino diseqc 1.2 project because it is too much work. And for what gains?
All I need is the actuator to move precisely to a given satellite when it is selected. Really nothing more than that. I also think it is a good idea to be able to see the current being drawn as the dish moves, and have an amperage meter installed that shows 0.00 or two decimal places.

The only thing I would add for my current dish moving system is the ability to see the motor counts on the tv screen when the motor is called. It would be nice if I could figure out an easy way to do that.
