Birdhouse camera: live demo

healthy Pulse 59820323 · 2026-11-13T22:41:44Z · Changes things: adopted Playbooks (A4 demonstration)

A solar nest box camera. Two Playbooks the owner adopted move its zoom, inside the owner's envelope; the infrared light changes only at the button. HEART runs on the camera itself: an ESP32-S3 camera board in the nest box, with a push button outside the box.

Next in its story: connectivity.link-lost in about 2 minutes.

What it changed, and who decided

A replay: the Action log of its one-hour story, the same changes every hour, as the downloadable simulator records them. On this page nothing is really asked, approved or changed.
