Hi guys, i want to build a LOW COST anemometer.
I have dismantled an old Hard Disk, and i've made 3 holes on the side of the central axis of the drive (sorry for my english!), to screw the 3 lives.
The cups are from olds plastic eggs from Egg's day.

I've spent €0.60 until now, to buy the lives.
Now the problem: I have a cyclocomputer (5 yo) and doesn't have the sensor.
I hope the sensor works with the hall effect, it has 2 contacts on the rear side, and they emit a small tension;
i don't know how to build a sensor or how i can procurate it (in an elecronic shop, i've said: give me a FET Transistor and they did not know what it was...)

Please give me an hand!
