Hi All
I was here a few years back because I wanted to build a wind direction meter. Various life events outside of my control distracted me but they're all sorted now and I'd like to resume with this...
I want to build a wind direction indicator.
It's got to be analogue rather than digital with LEDs because I want a hand on a dial to physically spin round to the correct compass bearing that indicates the direction of the wind.
My idea is to put a small weather vane on top of my chimney (I'm in a listed house so it has to be pretty much invisible and I'm surrounded by other buildings so the chimney top is pretty much the only location where wind direction isn't blocked).
My plan is to use synchro motors. One attached to the bottom of the wind vane as the "transmitter" and a "receiver" motor that drives a compass needle on the wall in the kitchen at the bottom of the chimney and which will mirror the position of the transmitter motor.
The two motors will be linked with wire so it won't be a remote/radio system because that's beyond my skill level which is very basic.
I've been looking at this motor on Amazon and wondered if this would do the job.
What I'm trying to achieve, somewhat ambitiously, is a similar functioning wind direction indicator to that in the library at the National Trust's Coleton Fishacre. I contacted them about it and they kindly sent me the information that I've attached here.
As I say, my knowledge is basic so please bear with me but if anyone can tell me if I'm barking up the wrong tree or can suggest better methodologies or a different motor to use, I would appreciate friendly input.
Many thanks
Joe
