Day 1: Design Integration
Initial system integration work focused on subsystem validation, CAD model consolidation, and design backbone acquisition for band integration.
Subsystem Validation
Conducted comprehensive testing of all subsystems to ensure proper functionality. Identified and resoldered any defective joints, verifying that each subsystem operates correctly before proceeding with full system integration.
CAD Model Consolidation
Exported CAD models of all PCBs in the final design and imported them into a unified CAD assembly. This consolidated model provides a complete view of the system's mechanical integration and spatial relationships.
Integrated CAD Model: Exploded isometric view of the complete system assembly, including all PCBs (pulse oximeter, OLED/accelerometer, speaker/amplifier), main housing with transparent enclosure, and wearable band components. The model shows the spatial relationships between electronic subsystems and mechanical structures, enabling precise integration planning.
Band Design Backbone
Acquired CAD design files for Apple Watch form factor integration, enabling compatibility with existing band designs and standardized watch components. This provides a proven mechanical foundation for the wearable subsystem.
Resuming the daily schedule tomorrow with parallel work streams prioritized according to the critical path. Tasks that cannot be completed during scheduled days will be shifted to buffer days on Saturday and Sunday to maintain project momentum.

Data Integration Plan and Resources
MQTT-based data integration strategy for coordinating sensor data streams from multiple subsystems across the MirrorAge system.
MQTT Protocol
Message Queuing Telemetry Transport (MQTT) provides a lightweight, publish-subscribe messaging protocol ideal for IoT device communication. This approach enables decentralized data exchange between all MirrorAge subsystems, allowing each board to publish sensor data and subscribe to relevant topics for coordinated system behavior.
Server Hosting Strategy:
Initial development and testing will use a laptop-hosted MQTT broker. In a later development spiral, the server will be migrated to a dedicated Raspberry Pi Zero or Raspberry Pi 5 for standalone operation and improved system portability.
Each subsystem board (pulse oximeter, OLED/accelerometer, speaker/amplifier, load cell) will publish sensor data to dedicated MQTT topics. A central interface or server component will subscribe to these topics, aggregate the data, and coordinate system-wide responses. This architecture enables:
Decoupled communication between subsystems
Real-time data streaming from multiple sensors
Scalable architecture for adding new sensor modules
Flexible server deployment (laptop → Raspberry Pi migration path)
