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.
- mycall 7y agoI've gone through multiple RPi on my boat. Maybe if I epoxied the board it would have a chance.
- londons_explore 7y agoMost epoxy isn't very flexible, and cracks leading to leaks over time. For something you can do at home, try heating the whole thing to 120C and dipping in hot glue.
- hanniabu 7y agoIdk 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.
- jmiskovic 7y agoWith 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.
