From the project
Some work I do for CycloneRocketry
This is an avionics control board for Iowa State's Cyclone Rocketry club. Our rocketry must carry a payload to a target altitude of 10,000ft. Score is determined by how close a team's rocket can get to the target altitude, among other things. To ensure we hit our target altitude, we have an air brakes system which actively calculates when and how long it needs to deploy it's air brakes system. The board additionally provides data-logging and radio-relayed GPS tracking.
