I built it using LNBits magic. 3D printed the case, grabbed an ESP32 board with screen and installed the firmware.
These would be great for businesses on Nostr requiring multiple people to make notes from a single account.

That's awsome, can you share a photo? Was it fairly straightforward to build?
Very easy to build. 3D printed case snaps together, no screws required. Firmware install takes 30 seconds. 🙂
