I've had good experiences with a 10" eInk dev kit from Pervasive Displays, purchased from DigiKey. Looks like it's out of stock right now, but they've got a 7.4" and a 4.4" form factor in stock: https://www.digikey.com/product-detail/en/pervasive-displays... https://www.digikey.com/product-detail/en/pervasive-displays... https://www.digikey.com/product-detail/en/pervasive-displays...

How do you program this? Is it easy to get started with?

At the low level, it's pretty straightforward to work with their dev kits. A Raspberry Pi + some jumper cables + a bit of python gets things going.

There are some quirks, since for the most part the board is optimized for internal update speed, not for usability. I ended up putting together some code to update the display given a PNG file, including some basic dithering for greyscale. And I drive all that from screenshots of a browser running in a virtual X terminal on the RPi. The update speed is not the best (several seconds from screenshot to render), but that's fine for my use case, since I'm using it for slow-moving info (weather, bus schedule, tides, etc.) and I'm better at writing HTML+JS for UI than writing bitmaps.

Recently, I tried to contact E-Ink, hoping to get information for an architectural use of some of their supposed products. I couldn't get any real information, conceptual pricing, development kit, summary of capabilities, or anything useful out of their sales staff. I repeatedly explained, I am a well capitalized entrepreneur wanting to incorporate some of their tech into my properties at scale, and that I have a dev…

Sony has done some interesting e-ink things, of course they were able to partner with e-ink

I wish I could buy a small and light E ink typewriter. Size of iPad mini, but with a keyboard, and stiff enough to be used on my laps.

A little bulky I think. Not something I would casually drop into my backpack.

Are we looking at the same video? The video should be the Onyx BOOX Typewriter. It's the size of a tablet and a keyboard cover. It's a HUGE improvement over the last entry I saw in this space, the hemingwrite[0].

Does anybody think having a gigantic e-ink desktop monitor would be rad for coding? The refresh rate might be a killer, but I wonder how your eyes would feel after 8 hours compared to an conventional monitor.

You mean like the Dasung Paperlike[0]? Consensus from the writers I know is it's pretty awesome. Not a lot of programmers use them at this point because it's black and white, so there's no syntax highlighting. It's also powered and connected via USB, so there is a delay when typing fast that could drive some programmers crazy. It's about the same responsiveness as a regular monitor hooked up with a DVI to usb adapter.
