My new home in Lubbock Texas is blessed, or cursed, with lots of wind.
At times the gusts can reach 60MPH. When the wind is about 40MPH, we have found it
impossible to do any work in the back yard. What I would like to see is a wind speed
indicator with an easy to read big dial, similar to many outside temperature dials.
Perhaps the dial would be about 12 inches in diameter with a clear plastic cover.
With such a device can look outside and determine if it is too windy.
The system might consist of a standard 3 cup anemometer. The
frequency of the pulses generated by the device’s internal magnet rotor would be
proportional to the wind speed. The frequency would be converted to a voltage.
That voltage would then be converted to an angle by a servo motor. The servo control
might provide about 270 degrees of rotation. With a calibrated dial, the readout
might range from 0MPH to 60MPH. The whole thing might be powered by a combination of
a rechargeable battery and a small solar panel. I solar powered white LED spot light
might be turned on at night, so the dial could be read at night. We often have high winds
in the middle of the night.
