The STF-1 team has been busy over the past weeks working with the Computer Science and Electrical Engineering (CSEE) department at West Virginia University. During this time hardware, firmware, and software updates had been made to allow for integration of the payload into the STF-1 stack. The video below shows one of the two boards in the payload triggering, or flashing the LEDs, as a response from the flight computer.
The LEDs shown are specially made using Gallium III-V Nitride-based materials at WVU. The payload is set to test the amount of shielding needed in the harsh environment of space to allow use for short-range distance measurement and shape rendering. The second board (not shown) utilizes photo diodes to provide the measurements needed for the experiment over the duration of the mission.
