Hi, my name is Alex, and I'm the project lead at EI2030 (https://ei2030.zulipchat.com/register/). The goal of EI2030 is to promote healthier computing practices and connecting people who are interested in discussion, learning, and collaborating.
We are working on building an open-source e-ink laptop. We are in the early stages of our first prototype, Archer (https://github.com/EI2030/Archer), and published an article discussing some of the challenges (https://alexsoto.dev/challenges-building-an-open-source-eink-laptop.html).
We are interested in using the TERES-I, modifying the chassis for an eink screen, and creating an open-source epdc expansion module. We are interested in hearing from people who have the TERES-I about this idea, suggestions/comments/questions and also, if any of this interests you, let us know over on our Zulip (https://ei2030.zulipchat.com/register/).
