wind instrument

Weather instrument with anemometer and wind vane.
Made with 4 printed parts.

- there is a 5mm screw attached on the bottom part (40 mm long in my setup).
- a 608zz bearing is fixed between rotor and cups with 3mm screws.
- a 9mm magnet(from a bicycle odometer) is inserted on the rotor
- the wind speed is calculated with a reed switch

- for the wind vane, a continuous single turn potentiometer is used

Use with arduino as described here:

Update:

The electronic I use are the following:
- one potentiometer for the wind vane, just an example bellow but can be other type. Secure it on the 'top' part.

- one reed switch (any type) triggered by a magnet attached to the rotor. it is inserted from inside into a piece called, by me, 'bottom'. secure it with hot glue
- an arduino mini to
