E-paper shopping list for the M5Stack PaperMono, with a FastAPI server and phone web UI
Firmware and companion server that turn the M5Stack PaperMono e-paper device into a fridge-mounted shopping list. The C++ app shows items grouped by aisle with touch UI, offline edits, and syncs over Wi-Fi with a FastAPI server offering a phone web UI, plus optional AI-powered aisle sorting.
Why now: Just shown on Hacker News as a Show HN project — a complete, working e-ink fridge magnet app (~2,400 lines of C++) people are reading as both a household tool and a PaperMono firmware reference.
Who it is for: M5Stack PaperMono owners wanting a smart shopping list, and embedded developers looking for well-documented e-paper firmware to build on.
