For the UCAR project, we have an infrared camera to record thermal images of the ground as we fly. Synchronizing these images with our radar system required us to design a small, robust controller. Using a Teensy USB development board, I am able to watch for voltage changes from our radar system, and output the required PWM signal to trigger the camera. This is an incredibly simple solution – exactly what we needed! It will connect in with our radar on one side, the FLIR camera with the other, and has a small micro USB port to power the controller. Beauty in simplicity! Attached is a memo explaining the process.
