That's how I think about it too. E-readers are vertically integrated devices: the hardware, software, UI, and refresh behavior are all tailored around reading. E-ink tablets like reMarkable are similar, but optimized around writing and

In normal use, we don't expect fast refresh to significantly reduce an E Ink panel's lifetime. The E Ink material itself is long-lived, the main stress is on the driving electronics and waveform behavior during refreshes. Our appr

The stylus solution is provided by E Ink to us. E Ink made the switch from EMR to USI a few years ago, so most E Ink devices, including the Modos Flow are using USI now.

Our driver board works with color e-ink screens.

Yes, this is one of the areas I’m most excited about; it makes e-ink more practical for everyday use and opens the space for experimentation. In the long run, as the community grows and more people get involved, we’ll see even more possibil

Yes, that’s the mental model I’ve been working from. Variable refresh tied to user input makes a lot of sense: short bursts of speed for navigation or editing, then settling into a low-power static state. Part of the challenge is deciding w

We’d like to offer a kit for the MNT Reform, and possibly the Framework, in the future, though it’s not part of our current roadmap.

> Maybe you can optimize many of them away (if some parts of the screen don't move, especially if software was rewritten to optimize for the display). Yes, that’s definitely something we want to work toward. As the community grows,

I agree with your points. I would add: - Making the project open allows people to reuse displays they already own. - Others can contribute and build on what’s been created. - Open source firmware, documentation, and the driver board make de

Thank you for your thoughts and support. I agree, doing this in X11 is definitely doable. I’ve seen others achieve similar results by running a daemon that listens for damage regions. I hadn’t considered using a custom backend video driver;

Can't wait to see what you have in mind ;)

Great! The board uses about 1-1.5W under continuous use with no OS/kernel power optimizations.

Three years ago, I posted about modding a ThinkPad T480 into an e-ink laptop: https://news.ycombinator.com/item?id=26245563 That turned into a community project and eventually into building our own FPGA-based e-ink display

At 0:47, both sides use the same e-ink panel, the left in outdoor conditions, and the right indoor. Latency was one of the challenges we addressed, and our driver board supports different panels, you can use one with lower glare if preferre

Thank you for your kind words. I agree that small teams can achieve a lot. We’re grateful to NLnet and the EU, whose support made this project possible and especially in overcoming complex challenges. We’ve made a point of attending confere
