Derek Lai

Electrical Engineering student at UCLA working on analog electronics, computer vision, and local-first software. Most of these projects are active works in progress; each repository documents what currently works, what remains unverified, and where the project is headed.

Projects

A physical 5 V transistor astable oscillator with potentiometer-controlled frequency, two switched timing capacitors, an RC-filtered passive buzzer, and a button-controlled LED and audio fade. The repository includes the completed breadboard, LTspice model and measurements, and design history. The next phase will use computer vision to estimate the board orientation and control positions from photographs, then configure matching LTspice simulations.

A Windows application that imports wearable health data, calculates explainable sleep and energy metrics, tracks personal trends and feedback, and provides AI-assisted coaching while keeping the underlying data and calculations inspectable.

A local discovery engine that collects public internship, research, program, and event listings, reconciles duplicates, detects changes, and generates compact review queues for later verification.

A private Windows lecture-transcription and dictation application that uses OpenVINO across available Intel NPU, GPU, and CPU devices, resumes interrupted transcription, and exports timestamped transcripts in multiple formats.

A Docker and WSL environment for running coding agents against one selected Git working tree while isolating the rest of the host filesystem, credentials, and Docker socket.
