Week 13 - Break, midterm review

Project Tasks and Timeline Overview

The project is organized into several overlapping phases spanning from May 15th to June 13th. Each phase focuses on a critical aspect of the development process for the driver stress and mood monitoring device.

Phase 1: Design & Preparation (May 15 – 25)

CAD Design: Designing the device architecture, sensor housings, and mechanical components.
Circuit Design (PCB): Developing and validating the PCB design for the sodium ion detection system and overall device integration.

Phase 2: Fabrication (May 22 – June 3)

3D Printing: Fabricating PETG enclosures for housing the device's components.
PCB Assembly: Soldering and assembling the XIAO ESP32S3 breakout boards and ensuring signal integrity for the biosensor.

Phase 3: Assembly & Alpha Testing (May 28 – June 3)

Mechanical Integration: Mounting sensor modules with neodymium magnets and integrating the Raspberry Pi with the output display.
Functional Verification: Testing data transmission, calibrating the sodium sensor with saliva samples, and verifying LED feedback response.

Software Optimization: Enhancing facial recognition algorithms and refining LED feedback.
User Experience Tuning: Improving the interface and output screen for real-time mood and stress level display.

Phase 5: Final Validation & Media Production (June 10 – 13)

Demo Video & Documentation: Recording the project demonstration and preparing final documentation for delivery.
