hi to all!
Recently I started a research to build a portable anemometer. I tried to build an easter egg, but I didn´t find the 3-cup helixes to buy. So now, I´m trying to build a 3 transistor vector anemometer, that can be found here:
h**p://www.edn.com/archives/1997/090197/18di_03.htm
the idea seems to be good, but unfortunately, neither the article nor the figure/schematics are clear concerning the components used to build this anemometer.
So I have two questions to all you people.
Have someone built this 3-transistor vector anemometer? Is this works good?
Can someone provide the component's list of this circuit?
Best Regards
