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)

(...) 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 (...) (26 years ago, 20-Jan-99, to lugnet.robotics)

You are correct I did mean "Anemometer" - I'd love to call that misspelling a typo but I realise I did it twice today *sigh* - I do know the correct way anyway :) I was thinking of the windmill/current concept - though am open to better suggestions.

Daniel, Peter Hesketh posted a similar suggestion, and yes the motor may be too firm for the job. I'll play around and do some testing, this week or as I can get time. Then I'll post the results. My goal is to end up with a pure Lego anemometer or (...) (26 years ago, 20-Jan-99, to lugnet.robotics)

It occurs to me that a pure Lego solution could be constructed fron a fibre-optic doodad and a light sensor. Get your mechanisim to rotate the fibre-optic rotator, use one fibre pointing at the light sensor, and bingo! instant anero...wossname. and (...) (26 years ago, 21-Jan-99, to lugnet.robotics)

There is a better way to use the fiber optic doodad as a rotation sensor: just connect it to the RCX on an input configured as a light-sensor and count pulses in electrical resistance. Read more here: (URL) -----Original Message----- (...) (URL) (...) (26 years ago, 21-Jan-99, to lugnet.robotics)
