A space-constrained custom PCB combining an ESP32, BQ21040 lithium-ion charger, TPS63001 switching regulator, USB-C, and I2S microphone—designed for a wearable LED project where thermal management and miniaturization were the primary engineering challenges.
A lighting and smart home design for a three-story property being converted into a short-term rental. The engagement covered power architecture, rail planning, power injection, and integration with Home Assistant — with design recommendations on hub hardware, voice control, and sensor selection.
Black Beauty is the third iteration of Lit, featuring refined construction techniques, weight optimizations, and a custom 3000mAh power pack. While the hardware achieved significant progress, challenges with firmware stability and power system design highlighted areas for future refinement.
A series of three prototypes - based upon the ESP8266, ESP32-S2, and ESP32-S3. These were built to help me explore the limitations pertaining to processing power, refine the power supply/battery management system, and to provide me with enough devices to test out the faculties for commmunication between devices, to enable wireless synchronization, and ultimately enable me to realize the core concept behind this project.
Lit Glamour Alpha pushed the boundaries of wearable tech, blending custom double-sided LED panels, advanced optical engineering, and sound-reactive features. This ambitious first phase laid the groundwork for scalable, innovative designs while overcoming challenges in power, weight, and usability.
