Anemometer is made from 3 cut 2" PVC caps (cups), 1 cut 1" PVC reducer (hub), 1 cut 1 1/4" cap (bearing cover), small threaded rod/nuts, 5/16" threaded rod (mount), ABEC 9 roller blade bearing, 5/16" jam, lock and castle nuts, cut sheet aluminum (pickup mount) , one small round magnet and a Sigma bicycle computer.

The weather vane is sitting on a Maxtor Hard drive motor and bearing. The vane consists of 1 3/4" PVC cap, 1 3/4" PVC plug, small threaded rod and nuts, drilled trimmed and cut fishing weight and a small piece of sheet aluminum.

I have yet to put a potentiometer on the vane. In the end I plan to finish it as a complete weather station, with temperature sensor and barometric pressure sensor. Maybe a humidity sensor. I have not decided yet. This is all in preparation of building a home brew wind generator from Volvo strut parts.

The anemometer starts up in as little as 1 MPH breezes and has been very accurate. The weather vane is suffering from too little tail and too much weight on the nose. I have already made another one. Just have not installed yet.
