# PiBuddyCam: reconstructing Buddy3D camera cloud behavior

> PiBuddyCam recreates the Prusa Buddy3D camera's cloud communication on a Raspberry Pi Zero 2 W using a protocol the author says was recovered from firmware. It registers with Prusa Connect, uploads snapshots, follows camera settings and answers WebRTC live-view requests; protocol documentation accompanies the implementation.

## Requirements & limits

- **Prerequisites:** Raspberry Pi Zero 2 W, CSI camera module and microSD card; a Prusa Connect camera token is needed for cloud registration.
- **Limits:** The author reports that Prusa Connect may hide live-view controls, and 90°/270° rotation remains to be checked on hardware.
- **License:** MIT license.
