I don't have an iPhone.
And the flip phone battery keeps dying after a day at the River.
Can I just use my calculator instead and just leave the results here when I get back home to the computer?

Oh, and,
Do you just need the average or would having data on the gust help out?

How about a variation on the above: The spinning rotor generates a magnetic field. The magnetic sensor in the phone (used for compass function, I think) detects the period of the magnetic field variation due to the spinning magnets, and then calculates the speed of the wind meter turbine and thus the speed of the wind.


Hi Prevett,

You pretty much nailed it. But several other people had good ideas. So your prize is a custom Gorge forecast and suggestions for the best sites for quality wind and GLASSY swell on your next vacation to the Gorge. Just mail me at mike@iwindsurf.com
