For my undergraduate thesis project, I used Altium Designer and PLECS to design a current source inverter featuring cutting-edge monolithic bidirectional gallium nitride switches. I successfully validated it on a three-phase resistive load with plans to deploy it as a variable speed drive for industrial PCB-stator axial-flux PMSMs.

I collaborated with two other students to design, build, and test an electrochemical impedance spectroscopy board that characterizes lithium-ion battery modules. We used Altium Designer to layout the PCB featuring a half-bridge IC, Hall effect sensor, SPI ADC, and Teensy 4.1 microcontroller.

I designed, breadboarded, soldered, and debugged an LM317-based adjustable linear power supply using KiCad and a digital multimeter. It features voltage indicator LEDs driven by a Schmitt-triggered LM339 and a resistor ladder.

As a licensed amateur radio hobbyist, I designed a custom Morse keyer based on an Arduino microcontroller. The device was drawn in Fusion 360 for 3D printing, programmed using C++, and can interface with my computer via Python over the serial port.

I designed and built the avionics system that initiates and controls launch procedures of UTAT's hybrid- and liquid-engine rockets. It features li-ion batteries, buck and boost converters, a Raspberry Pi loaded with a custom GUI, a DAQ board for load cells and pressure transducers, actuator controllers, and a wireless radio transceiver.
