build a sun photometer using a LED diode.
build a sun tracker using RC model servos
operate the servos using the left and right audio output from the smart phone
add a solar panel and battery
develop software to track the sun every day, recording time, elevation, azimuth, and flux level, with fish-eye images of the sky taken for good measure. Use cell phone or wireless link to email the data to your home lab once a day. Calibrate the photometer. Use the sun
