Project Introduction

The process of designing medical devices necessitates meticulous planning and steadfastness in seamlessly integrating various components such as hardware, software, and external enclosures. With the objective of preparing for my undergraduate capstone project, I conducted a comprehensive design sprint, wherein I successfully undertook the development of a light box. This endeavor entailed the utilization of technical proficiencies to create a wearable photoplethysmography (PPG) temperature sensor.

Contributions & Outcomes

The project involved the design and development of a CAD enclosure for a light box, which was intended to seamlessly integrate with a printed circuit board (PCB). The PCB featured a voltage-regulated circuit with inverse polarity protection, specifically designed to illuminate an LED. To achieve adjustable brightness of the LED, a 555 timer was incorporated into the circuit design.
