I was previously working on an epaper phone project. A minimalist/modern feature phone. Anyway, the company pivoted and has agreed I can open source the hardware.

I decided to ditch GSM and just use wifi. I have been thinking it could be a good platform for encrypted messaging using Matrix/Riot. Unfortunately I am not a software developer. If anyone is interested in helping out, let me know.

Your cabin project is interesting! Any updates? How's it going?

Thanks, it is really enjoyable. Hiking right outside my door and exceptionally low expenses. I am planning a v2 soon that can be built more easily(no excavator), be significantly larger(my current cabin doesn't have an indoor bathroom), and still be low cost.

Its amazing to learn about 500 yr old buildings in Germany and England using low cost, simple techniques. I hope more people might realize that this is a lifestyle option.

haha. that's an awesome cabin! :) never thought I would end up reading about your cabin project when I clicked on the link about Signal :D

good luck for v2. Hope to read about it on your page.

This looks cool. Thanks for linking! What epaper hardware are you using?

Sharp memory LCD. It uses a simple SPI interface, can refresh at about 30fps, but has no greyscale unfortunately.

30 fps is pretty good for an eInk screen, and UI design for a two-tone black or white screen seems like a really interesting challenge.

Maybe I should build one of these...

Ill be doing a small run of prototypes in about a month. Could assemble one for you if you want to hack on it.
