I plan to do some trials up on the moors in the car with my wind instrument
and a hand held wind speed device and work out pulse per min per mph etc etc


IF you can see any major flaws in my plan please tell me be fore I find them
the hard way..

I guess a fair bit of the cost is the software, which isn't particularly
useful from my point of view as I don't use Windows.

I guess it should be relatively trivial to build something that would
spin in the wind and generate a pulse for each rotation. How would you
calibrate it though?
