You can use Parabola-rM[1] with a reMarkable 1 tablet as an all-in-one solution, and like the T480 can be totally freedom-respecting using only libre software. [1]: http://www.davisr.me/projects/parabola-rm/
Does it also work with reMarkable 2?

Re: Building an E-Ink Laptop
#122Ha, this is a good write-up on a very interesting topic I’ve been thinking about a lot myself recently. The setup I’ve been thinking of putting together is similar, except I’ve been wanting to pair an e-ink monitor with something like a Raspberry Pi 400 ( https://www.raspberrypi.org/products/raspberry-pi-400 ) for a kind of deliberately-slow, ultra-low-wattage dev and writing environment. End result would be extremel…
If slow is what you are looking for, there has finally been some movement on building controllers for bog-standard e-ink panels like you find in kindles. Refresh rate is far below the 75hz in this project, but the price is too. my 10 second search didn't find the project notes I had in mind but I'm pretty sure this is the same end result:

No, I'm stating the fact that other companies can't improve the same exact technology (as defined in the patent).

That's equivalent to saying Samsung can't improve the same exact technology used by AU Optronics. Rightfully so.
> So this isn't about other companies still being able to make improved eg. OSes in the general sense, but if they can build improved OSes that also leverage the same patented techniques where needed (and they can't)
I think I've explained my point clearly enough. I'll wait for you to give some factual evidence as to which patent you believe is giving rise to your statement of "they can't".

#124There used to be Siemens-Fujitsu laptops with transflective displays for working in direct sunlight quite a few years ago. They were extremely expensive. I had a search running on eBay for several years but not a single unit turned up. They must be woefully outdated by now.
Re: Building an E-Ink Laptop
#125Hey folks, I've recently had the idea of building an e-ink laptop from the devices I had at home. I decided to document the process and share each step of the way: Some of the posts planned for the series are: Dasung Paperlike HD-FT teardown, Thinkpad T480 teardown, Creating the prototype, Installing and configuring NixOS, M-x e-ink-laptop-mode If you have any questions or comments, feel free to reach out.
Good stuff!
I did a screen conversion on a thinkpad t430s which I still have (not Eink, just a better LCD). Do you know of any 16:9 eink displays that take eDP as input? Or anything that would fit in a 14” chassis?
Just beginning to get into the eink world so some direction would be super helpful. Would definitely be up for swapping one into my thinkpad.

What is bistability in this context? Confidence that the ink will rest in 'on' or 'off' configurations? How does that relate to greyscale with multiple configurations and how does ClearInk manage pixel state?
Clearink does not rely on the foreground pigment particles coming to "rest" at a fixed position relative to the background pigment, ie: achieving a stable state. Instead they rely on driving the field for as long as the foreground is needed. As soon as it decays, the background pigment instantly rises back to the internally reflecting top plane. This allows the display to achieve much faster speeds since the pigments…
From what this description sounds like, the foreground pigment would only remain at the forefront so long as a charge was applied. Doesn't this defeat the energy savings of eInk in that once you have updated the display it doesn't cost anything to hold its image?

Thanks for taking the time to argue with this person. I withheld--despite the downvote brigade--because I presume he has some other agenda for promoting this story.

#128Lenovo had a dual screen botebook with e-ink https://www.engadget.com/lenovo-thinkbook-plus-gen-2-i-e-ink...
Yes, but the e-ink screen was on the wrong side of the device. People like me and the author need an e-ink display for writing in broad sunlight.
Probably not what you are looking for, but this: https://getfreewrite.com could be good for you.
Re: Building an E-Ink Laptop
#129I did try to hack something simmilar to this by the way of Onyx Boox e-reader running Android and supporting my bluetooth keyboard and it was more of a novelty than anything else :D
But it was fun to write in direct sunlight, in just a slightly less of a hipster fashion than using i.e. https://getfreewrite.com/ :D

Yes, it would lose the image once the display is no longer driven. The main attraction is the removal of the need for a backlight and the sunlight readability and all the other advantages that come from using actual pigments.
