| 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. |

Bill, The parts are now to hand; thanks a lot. I'll play around and see what I can make of them. Eug |

I found a wind vane and arm, it'll be on its way to you, so you'll have no excuse when it arrives. bill |
| Eugene:
Bill, You are not only very kind, but nuts too! What voltage / current do I apply to the pot to make things circumulate? Eug |
| BillTodd:
From memory, mariner used 10v but it will probably work with 5v. it's a1k pot. bill |
