Projects

Electrocardiogram

Designed and built circuit that filtered, amplified, and analyzed ECG signals, enabling accurate heart rate detection through real-time processing.

Circuit Simulator

Developed a circuit simulation tool inspired by SPICE for analyzing electronic circuits using Python.

Arduino Nano Breakout board

Designed, prototyped, assembled breakout boards for NULunabotics rover for Arduino Nano and board designed in KiCad.

Power board

Assembled and debugged a power board to step down 12V to 5V, enabling reliable power delivery to the rest of the rover. Which included small SMD components.

RISC-V Single Cycle Processor

Designed a RISC-V single-cycle processor, optimizing instruction execution through effective architecture implementation using SystemVerilog and RISC-V instruction set.

Modular Antenna Mount

Designed and implemented modular mounts for a high-gain lens horn antenna using SolidWorks & SDM 3D printing.
