Printed Circuit Boards

20dB Amplification Module

Designed a differential-pair, common source amplifier achieving a low frequency gain of 20 dB. Circuit features a JFE150 N-channel JFET and SMA connectors. My only regret is not adding any silkscreen art.

DC Chopper Apparatus

Modified the laser-cut acrylic supports and designed a PCB to minimize extraneous wiring and reduce electrical noise in an educational lab experiment for USC’s AME-341 Mechoptronics class. The board enables investigation of PWM duty cycle vs. DC motor RPM using a phototransistor, improving measurement repeatability and robustness. Custom polar-equation silkscreen art spans the front layout.

Gantry Control Suite

Developed a PCB for a 2-axis gantry used in a turbulent jet flow experiment. The board integrates a pressure transducer, x/y limit-switch inputs, and a visual indicator LED to signal gantry boundary conditions, supporting safe and repeatable airflow characterization. Mathematical silkscreen art populates the back layer.

Differential Op-Amp Module

Created a PCB to provide students with an intuitive and configurable module of a differential amplifier where different gains can be selected to accommodate the experiment at hand. The layout prioritizes clarity, symmetry, and instructional usability, complemented by custom polar-equation silkscreen artwork I plotted in Desmos.
