Final Design of the Hunter Wind-Clik Prototype

Final Wind Tunnel Test of the Wind-Clik

Cross Section of the Wind-Clik

Test Site = UCSD's Wind Tunnel at the Undergraduate Laboratory

Preliminary Test of The Wind Clik

Testing the Wind-Clik by Coupling it to a DC Motor

Signal Generated by Rotation of Wind Cups

Cross Section of Magnet and Coil Housing

A Diametrically Magnetized Cylindrical Magnet Provided an Electrical Signal in the Above Orientation upon Rotation of the Wind Cups

The signal from the anemometer provided by Hunter Industries was converted using an op amp as a comparator to output a step function.

Final Electronics Layout

The anemometer provided by Hunter Industries was tested in a wind tunnel to find a linear relationship between RPMs and wind speed.
