Create your own computer controller dual axis solar tracker in under an hour, using only a screw driver.

The sun is awesome, and so is solar electric power generation.  Unfortunately for solar panels, the sun moves.  To counter this you can make a tracker that follows the sun and allows for even greater energy production.  This is accomplished by using two micro servos, four sensors, an Arduino Uno, custom laser cut wood, and a whole lot of screws.  By popular request the Dual Axis Solar Tracker was designed to be non-soldering, and all you will need are some screw drivers and a wire stripper.

The Dual Axis Solar Tracker also comes with a very handy solar cell and voltmeter to gather solar data for use in projects and experiments.
