Would be interesting for use on a boat. Generally you want a fast refresh rate but once a minute would be fast enough for most users. The problem with navigation displays on boat are
1. daytime visibility
2. long term waterproofing in a saltwater environment
With this setup you could mount a raspberry pi W on one side of the fiberglass to interpet NEMA 2000/0183 data and the NFC chip, and the waterproof, hermetically sealed e-ink display on the other, held on with velcro or neodymium magnets etc.
Idk about new hot glue, but I have some old projects with hot glue from about 15 years ago and it's starting to dry out and crack. Something to keep in mind if looking for longer term.
With this solution you could never be sure that pi is functional and displayed data is fresh - you'd have to always compare display clock with wrist watch or something.
