Platinenlupe: reconstructing an EarVision camera protocol for browser viewing

Platinenlupe reconstructs an EarVision Wi-Fi ear camera's communication for browser-based PCB inspection. The author documents APK and firmware analysis that recovered BLE wake-up, Wi-Fi access, UDP JPEG framing and light control, then implements a two-board ESP bridge and local viewer.
