Picture of a home made "Anemometer" I constructed: Used to measure wind speed.



Materials Required:

1. A small DC Moter which can be purchased in most electronic stores.

2. 3 small plastic cups or 3 metal cups.

3. 3 six inch ling steel rods.

4. 2 Conductor wire.

5. Small steel plate.

6. Fitting.

7. Solder: To solder the three 6 inch steel rods to the small steel plate.

8. A small "DC Volt" Meter which can be purchesd in most electronic stores.

9. Some good "Water Proof" glue.




"How To Construct The Home Made Anemometer" 



1. Attach the "Fitting" to the shaft of the "DC" Motor.
   Tighten with a screw driver or allen wrench.


2. Solder the "Small Steel Plate" to the fitting on the motor.

  
3. Solder the 3 Six Inch steel rods to the small plate on the motor.


4. Drill a hole on both sides of the plastic or metal cups.


5. Slide the plastic or metal cups over the ends on the six inch rods.
   If the cups are plastic glue the cups with a good water proof glue
   to the rods.


   If the cups are metal you can solder them to the six in steel rods.


6. Connect the "Motor" of the "Anemometer" to the small "DC" meter
   with the plus wire on the motor to the plus contact on the meter
   as shown in the below picture of the "DC" Meter. 









7.  Calibrating the "DC" meter is not to difficult: Get the
    wind speed  from you local "Natinal Weather Service". Open 
    the meter to get to the face of the meter. You can than 
    mark the face in "MPH" after some time of experminting with the
    anemometer.
