I built a tremolo pedal using a transistor-based adjustable phase shift oscillator. After learning more about guitar pedal design from my previous project, I integrated true-bypass switching, anti-pop resistors, and a 9V AC/DC adapter instead of a short-lived battery. The pedal also features amplitude and frequency control, with everything soldered and neatly packaged in a custom 3D-printed enclosure.

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.

I applied my recently completed electronics course to design a fuzz pedal for my electric guitar. It is based on a common-emitter NPN Darlington pair and features a volume control and power indicator, all soldered and neatly packaged in a custom 3D-printed enclosure.

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.

I designed and built the avionics system to initiate and control launch procedures for our hybrid- and liquid-engine rockets. It features Li-ion batteries, buck/boost converters, a Raspberry Pi loaded with a custom GUI, a DAQ board for load cells and pressure transducers, and a wireless radio transceiver.
