Finally I got enough time to build the wind measure gadget I should have done before working on my wind turbine.
It is still not configured to show the real wind speed but that will finished later.
You can read a built report (in german) on:

u sure the diameter of the cups with the magnet on it is equal to the diameter of where u put the magnet on the bike?

@wow1022:
I am sure the diameters are definitely NOT equal. Nevertheless the diameter is not of importance when you measure RPMs. You have to adjust the diameter settings in the tachometer (see the linked build report in the description above for instructions).
