The 'signal source' can be a potentiometer or a 10-throw switch, etc. The main issue is that it represents a linear, variable (analog or discrete steps) voltage divider (and I believe the circuit should handle the supply voltage on board). Tomorrow, when back in the workshop, I'll put together a preliminary circuit diagram and part list, and make that available. Personally, I want to try out a simple, homemade inductive angle sensor instead of a pot-meter, as I think it would be a lot easier to waterproof a pair of coils [ref. attached image]. However, if that will work, then I would also need to handle AC signals, which again requires a different circuits. There was a few other questions asked, but I'll tend to those to morrow. Best regards, Jens Laland
