Show HN: PaperMono, e-ink fridge magnet shopping list with mobile web page

Fridge magnet shopping list on an M5Stack PaperMono (ESP32-S3, e-ink touchscreen), synced with a phone web app over Wi-Fi. Works offline, ~2,400 lines of C++.

This is a great wee device! BLE, Wi-Fi and LoRa on one board makes it flexible for way more than a shopping list, this is just what I built first. This firmware only uses Wi-Fi.

Fully vibe-coded with Claude Code, I didn't hand-write this. I wanted to see how Claude would get on with building something useful for a new hardware device.

As it's stuck to the fridge it's easy for the family to use, and it's already being used day to day which I'll admit is a first for a home built project like this

Hold on babe I gotta charge my fridge magnet…

Jokes aside this is cool

At first I thought “that’s a very specific shopping list for fridge magnets”. :)

Curious what you landed on for refresh, full flash or partial? Ticking off items one by one is exactly where partial update artifacts pile up on these panels.
