The nodes discover each other via UDP broadcasting and elect a leader using node name ordering. The leader manages a work queue, with an example implementation that distributes prime-finding tasks across worker nodes. Key learnings include memory constraints on ESP32s requiring serialized web requests, and that standard queue designs can be memory-hungry on embedded hardware. The project includes a web dashboard, a Justfile-based build system, and even 3D-printed housings for the ESP32 boards. ## Full article daily.dev links to this article rather than hosting it.
