Projects

3D Printed Doppler Shift Measuring Device

Physics capstone: crank-slider linear actuator + HB100 microwave sensor to measure doppler shift. Custom mechanical design, analog front-end, and ESP32 data capture.

Mechanism: 3D printed crank-slider for controlled linear motion
Sensing: HB100 IF output (mV-level) with metal target reflector
Analog: biasing + op-amp amplification to reach MCU-readable levels
Data: ESP32 streams waveform to a computer; oscilloscope used for final frequency/amplitude measurements

SolidWorks 3D printing Op-amps ESP32 Instrumentation

Multiterrain Aluminum Rover

SEDS structural rover: custom 5052 aluminum frame, jackshafts, drivetrain, and field-range telemetry. Led mechanical design, assembly, plus electrical + comms.

Frame: 5052 structural aluminum + corner brackets
Drivetrain: 24V motors (~24Nm/mot) with custom jackshafts
Power: terminal distribution blocks → buck converters, motor drivers, logic electronics, and drivetrain
Comms: rover telemetry range ~740m (field tested)

Mel spectrogram visualization from UrbanSoundAI

UrbanSoundAI (CNN + Spectrogram Generator)

Trained a CNN on UrbanSound8K to classify sound sources (dog bark, drilling, sirens, and more). Generates spectrograms from audio and runs inference on them.

Data: UrbanSound8K
Pipeline: audio → spectrogram → CNN classification
Output: predicted class with confidence + visual spectrogram
