# 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.

## Requirements & limits

- **Prerequisites:** Requires a compatible EarVision camera, an ESP32, a NodeMCU or second ESP32, and wiring for the documented bridge.
- **Prerequisites:** PlatformIO builds the firmware; local part identification additionally requires a vision model served by LM Studio, Ollama or a compatible server.
- **Testing evidence:** The author reports hardware measurements on a TXW810 camera with firmware 125.
- **License:** Repository code is MIT licensed; enclosure files use CC BY-SA 4.0.
