He is heavily involved with board bring up and troubleshooting to the component level and developing custom ground systems equipment with embedded microcontrollers and FPGA's. As a mentor, Davy brainstormed with a gifted student who created a SPI based custom board to emulate spacecraft, that allowed for testing a satellite power supply distribution unit before all of the radiation hardened subsystems were available. This design was leveraged in two different missions, with one being LVDS and the other being RS422 - using the same PCB. Davy also implemented a high voltage power supply controller using a low cost, off the shelf MIDI drum kit without being asked, that saved countless hours in the lab with multidisciplinary teams, since attention distracting text commands were able to be avoided with the SPI based custom controller.
