Currently on the solar eclipse team, SE2017 - The Sunspots, we are working on post flight analysis for NSE-012 and the photometers. The photometers seem to be overloaded when in full sun so we are working on developing shading schemes. the circuit diagram is below. We're using a op amp to boost the small current from the LEDto a voltage that we can read. We've yet to see what LED types can be used for varying frequencies. I would like to get readings at 4 different frequencies. We're taking our lead from Forrest M. Mimms designs. We want to find tune and calibrate the photometers tomorrow.
