I believe the word is anemometer... it's really just a form of pressure
gage. Were you just thinking of attaching a windmill to the motor to
produce current?
I've seen various ideas postulated on this list for pressure gages (or at
least limiters) for use with the Lego pneumatics system, but nothing has
come down the line that would be sensetive enough to detect the few psi
difference between static and total pressure at any reasonable speed. On
the tunnels here at Purdue, for the lab courses we have big sensetive
pressure gages, and on the big Boeing tunnel we have more sophisticates
and expensive things like seven-hole pitots and multidirectional hotwires
and...

| Bill, Interesting you should mention that. I've been toying with the idea of making a anenometer (wind speed tester) from a motor, but haven't over come the idea of how to calibrate it. You'd need to place a resistor in line to help avoid damage to (...) (26 years ago, 20-Jan-99, to lugnet.robotics)
