Designed and implemented a dedicated pad-control PCB for a liquid rocket ignition and launch system. The board communicates over CAN with the flight computer, servo and sensor boards, and distributes regulated 6V power over the same harness for downstream electronics. It manages remote arming and ignition sequencing, driving three independent pyro channels while maintaining safe-state logic throughout pre-launch operations. This system was used during static fire and launch campaigns and contributed to a First Place finish in its category at the FAR-OUT 2025 competition in the Mojave.
Built a first-pass power and control PCB to speed up underwater vehicle testing and reduce risk before the final revision. The board combines battery input protection, high-current distribution, and system communication so the ESC, servos, and Raspberry Pi can be tested early on one platform. It uses an STM32 with CAN, USB-C for bring-up, and microSD logging, and provides regulated outputs for the ESC rail, the servo rail, and dual 5.1V outputs for the Raspberry Pi and peripherals. An INA over I2C monitors current and voltage with telemetry sent over CAN, and a firmware-controlled MOSFET load switch supports safe power sequencing and fault shutdown. Embedded C in STM32CubeIDE was used to validate PWM control, CAN messaging, I2C telemetry, and logging during bring-up.
Led PCB layout work for a custom charge safety board in Altium Designer, translating the team schematic into a clean, manufacturable board layout. Placed connectors, protection circuitry, relays, passives, and test points with attention to logical signal flow, accessible probing, and practical integration with the larger electrical system. Used Saturn PCB Toolkit to estimate trace widths, copper current capacity, and via sizing so power paths and critical nets were routed with reasonable width and reliability in mind. Managed component spacing, grounding, connector orientation, and routing organization to support assembly, debugging, and safe operation, while also helping plan how the board would interface with the accumulator and surrounding harnessing.
Hello! My name is Emmanuel Che. I'm an Electrical Engineering student at the University of California, Riverside, graduating in June 2027.
I'm currently working on the Highlander Space Program liquid rocketry team, where I help with hardware bring-up, testing, and integration.
My main passion is hardware and PCB design. I enjoy turning ideas into real boards, debugging them on the bench, and improving each revision to make the system stronger.
I also love building with friends who share the same passion for engineering, because great teamwork always leads to better hardware.
