Hardware & Acoustic Design
Machine Health Sensor and Mechanical Test Bench (2026)
The target of this project was to develop a remote sensor that can detect mechanical failures when they occur and use acoustic cues to predict component lifespans. This would inform technicians which repairs are imperative and reduce unnecessary downtime. Current solutions are expensive and typically reserved for high-end machinery. Developing a budget-friendly option creates an opportunity to deploy this technology to a wide range of systems. To achieve this, a custom mechanical test bench was designed, and an Arduino Nano was loaded with a machine-learning model trained through Edge Impulse on collected acoustic data to detect faults.
PCB Design: Bass Headphone Amplifier (2026)
This project is a bass headphone amplifier designed from scratch. It is a four-stage circuit, powered by a single 9V battery supply. It's designed for bass guitar player who plays an active bass and with to practice silently under some settings and not have to carry a big amplifier with them.
Diffuse Sound Ambience Using a Circular Diffusing Speaker
To address the localization errors and lack of immersion in normal speakers, this project explored the design and characterization of a horizontally cone-shaped diffusing speaker. My teammate and I built a custom prototype featuring a conical diffuser and utilized the CLIO Pocket system to capture frequency response data. By isolating direct sound from reflections in a anechoic chamber, we analyzed the speaker's radiation patterns with and without the diffuser. The result showed signs on how specific geometric installations can broaden directionality and enhance the immersive sound field without complex multi-channel arrays.
