For your chat device, you might be interested in
checking out the Grey Cat collective,
https://greycat.co , they have a hardware kit that sounds similar to what you are
describing.
Unfortunately, I think their code is still closed source and last time I played with it
(August
2018), it was only demo and the keyboard was not yet implemented.
Alternatively, you could build your own box around a Disaster Radio. While it wasn't
designed to
have a screen, I'm sure you could adapt its code to print messages to a built-in
screen (probably
an SPI OLED is your best best) and take input from a physical keyboard (or a push button
matrix?).
I'd recommend getting in touch with sudomeshers in Oakland who could send you a
Disaster Radio
prototype to play around with. If you are able to get a prototype, I'd be happy to
walk you through
the code, since I'm the one mostly responsible for it's current state.
You can find the code and other resources here
https://github.com/sudomesh/disaster-radio
, there
are also schematics and board designs in there, if you are up for printing your own
circuit board.
Good luck!!!
