You’re proposing smart glasses with a camera and microphone that:
- Record video, targeting 4K
- Record synchronized audio
- Save recordings to a microSD card
- Connect to a phone for control, preview, and file transfer
No schematic, component selection, or PCB layout was created in this session; the project remains empty. The main unresolved engineering decisions are recording duration, acceptable glasses weight, battery life, live phone preview versus control-only connectivity, and whether 4K encoding is performed on the glasses or delegated to the phone. Native 4K recording typically requires a high-performance video processor, substantial power, heat management, high-speed memory, and a relatively large battery, so a split architecture—camera on the glasses with the phone handling encoding/storage—may be more wearable.
The next step is to define the system architecture and power/storage requirements, then select the camera, processor, wireless link, microphone, microSD interface, and battery system before creating the schematic. Execution stopped because your ACUs ran out.
