How can you "drive" a wind clock?
Noitoen:
It's very easy to make a contactless potentiometer that will last a very long time. Use a LED to shine on a LDR through a plastic disk with a "spiral" pattern painted on it. If you use 3 LDR's in a 120º configuration you can even get that three phase pot mentioned earlier.
Eugene:
Bill,
The parts are now to hand; thanks a lot. I'll play around and see what I can make of them.

I found a wind vane and arm, it'll be on its way to you, so you'll have no excuse when it arrives.

Eugene:
Bill, You are not only very kind, but nuts too!
What voltage / current do I apply to the pot to make things circumulate?

BillTodd:
From memory, mariner used 10v but it will probably work with 5v. it's a1k pot.
