Hey! This thing is still a Work in Progress.
Files, instructions, and other stuff might change!

Description
This is an attempt to build a complete anemometer from scratch.
I need such tool to prevent my sunblinds from being destroyed during storms; they need to be moved up beyond 15m.s⁻¹. This will be automatic ;o)
I will also design the measurement parts, and the electronic.
More info on logre.eu/wiki/Anemometer (sorry, in french).

Instructions
Ok, I think this is a close to final release.
I finally switched to a Hall effect sensor, instead of using a pickup-coil, which needs a lot of turns to be able to deliver a usable voltage. But this means very thin wire, which can break easily.
The electronic part is made with an Arduino; I will post the test code.
I didn't find yet a good material for laser cutting gaskets. Note that the stl files are generated for a gasket thickness of 0.1mm.
Hall effect sensor is from Allegro (A1101 or so). Magnets are from Supermagnete (S-04-03-N).

I have made gaskets out of the nitrile rubber used for gloves which is about 0.1mm.
It cuts nicely when stuck on the self adhesive carrier of a craft cutter.
Good idea! I'll try that.
