How can you "drive" a wind clock?

OK then Bill, back to the Pitot tubes - mechanically very simple

Yiss, Sorr, dats roight so t'is.

Im guessing at an 8 - 10' dia clock face. We have a cheapo wireless weather station that has an LCD display; no wind direction function (they are available) but it's surely possible to render the input in analogue form. If you are cleverer than me that is!  Andrews rotary encoder / Arduino /stepper sounds great but nailing it together would be beyond me without a very close to hand mentor. However I'd be quite happy for someone else to put the circuit together and then fit it myself.

BillTodd:
do you want the pot and motor shown in my video?

you may be able to fix / clean the pot (i have not even tried to open it)  I think the motor is ok but may need a front bearing.

PM me your address and I'll post it to you.

Eugene:
Bill,

That's extraordinarily kind of you. See PM.

Eug

BillTodd:
ok Eugene it's on its way.

My guess is that the fault with the pot is mechanical. Probably, one of the wipers has come loose - P&G usualy use a sort of wire brush that wipes both the main track and the input track.
