• Designed RP2040-based embedded system controlling a thermal paste dispenser. Utilized SSRs to isolate control signals, crystal PCB guard rings to reduce surface current leakage, and an ADC to monitor strain gauge output. Wrote C firmware to interface with the RP2040 over USB serial, performing a dispensing operation when a formatted command is parsed.• Designed UART to USB serial converter board to translate system debug data over micro-USB• Utilized embedded Linux (Buildroot) to perform a variety of system tests, including backplane Ethernet, PCI Express linking, I2C bus activity, and GPIO loopback• Performed Pierce crystal oscillator tuning and component selection to improve oscillator startup time, frequency stability, power consumption, and safety factor

• Designed and milled current telemetry PCB to monitor power delivery from battery and ground support equipment to electromagnetic thrust vector controllers (SLS TVC power). Incorporated Hall effect sensors, analog amplifier stages, signal MUXing, fault detection, digital panel meters, and modular design principles.• Designed solenoid optimizer circuit to reduce on-state power consumption of a plunger valve. Utilized high-side FETs for power gating, clamp diodes to protect components, and RC delays to time power switching.• Assisted in writing test and verification procedure for a transient-shunting circuit protecting downstream Environmental Control and Life Support System (ECLSS)• Integrated watchdog timers into testbed power supplies to automatically cut power when heartbeat signal not received

• Designed and constructed a portable AC load bank to simulate excess power draw during testing, featuring an adjustable wattage selector and tolerance settings to compensate for source error. Utilized 80/20 and large heatsinks to mount resistors, relays, and front panel controls.• Tested variable frequency drive designs to ensure compliance to UL standards and specifications• Operated IGBT rise/fall time, dV/dt, and breakdown tests to select optimal gate drive components• Utilized NI DAQ tools to monitor dynamometer and thermocouple data streams during testing
