Welcome to modern astroturfing in the social media age.
There is a build page on the github for the device.
I see no link to GitHub, but I do see two links to crowd supply.
There's no such link. Can't even find one through Google

Looks really nice. How much do you want for one? Surely not more than twice as much as the competition needs. /s
I'll wait until they make one with 300 screens I can flip like a book.
And each screen has infinite battery life! Oh and each is as flexible and light as I dunno, a sheet of paper maybe!
imagine a book you could plug in to change into a different book
I want VR recreations of famous libraries with full on books you can take off the shelves to read and homeless people washing their feet in the bathroom sinks
pair of 648×480 e-paper displays
Um lol no. I could see using a pair of Inkplate 10's connected by (at least metaphorical)) duct tape. Doesn't seem worth mucking with special hardware.
Every affordable e-reader I know of is simply too small though. I mostly want to read stuff like ArXiV preprints (A4 sized pdf's) so would want at least a 13" screen. Someone a few days ago posted a link to a 14" Android tablet with a semi-reflective display at around $300. It seemed interesting but I'd rather degoogle.
There are some hinged Waveshare displays that look nice but they are regular TFT displays so wouldn't be great for a portable e-reader with long battery time:

I hope you get what you want. Me I want something I could put in my pocket.
The small kobo kinda fits in a jean pocket, easily in cargo shorts or inside jacket pocket. Only comfortable for reading novels though. I prefer a little bigger even if it isnt pocket size.
I do like the old kobos. Fully hackable.
I like dedicated devices for things rather than all in ones. If you have the money of course.
Oh hmm, I just use my phone for that. It doesn't seem worth having an additional, limited purpose device. I assume a 7" e-reader is too big for a pocket.
The Inkplate 10 isn't pocketable but it's very light, easy to put in your backpack or whatever. I just wish they had a 13" version. The 13" Ipad Air is really very nice if you don't mind Apple products.
There are also some folding phones now with largish screens. A buddy of mine has one and it's nice. Too expensive for me though, and it's more Android.
Being able to fold down a larger "sheet" display so that it fit in a pocket would be pretty cool. Having extra room for reading things like maps and comic books is so much better than pinching and zooming on a pocket sized display. What you call limited purpose, I call functional design. I'm kind of over all-in-one devices. They've turned into Jack of all trades, but master of none.
Obviously that's not what this device is, but it got me thinking about why I'd want a device with multiple e-ink displays or a foldable display.

Yeah most 7" readers have the page turning buttons on the side which usually makes the device too wide for pockets.
The 6" readers fit my pocket quite well... So a foldable dual screen 6" sound like a pretty nice upgrade.
Most of what I use my readers for are reflowable text like epubs... But I guess if you could show a single page from a PDF across both screens then it might actually be big enough to be able to read while still being pocketable... You would probably want to go with the high resolution e-ink screens, like the one in the Kobo Clara HD (1072 x 1448). A combined resolution of two of those would be 2144 x 1448,
Hello there, just scrolling through and I saw your comment. You seem to know a bit about this topic. I'm currently thinking of buying a reader as I lost mine some time ago. I used a kobo and a kindle in the past and didn't see much difference. However, this thing about reading papers seems really cool. I have tried in the past reading PDFs on those readers without much success.
Do you think you have good options for reading articles/manuals? Consider I end up printing about 50 pages a day in articles I read. If I can turn that into something digital that'd be cool.
If an 8-inch screen is enough for you, then I recommend either the Pocketbook Inkpad 4, or the Pocketbook Color 3 if you want color. They run Linux and have a very capable PDF Reader (especially compared to Kindles)
If you want an even bigger screen then sadly they start to get very expensive, and usually ship with an already outdated version of Android and an underpowered SOC. And they also have the terrible standby battery life you would expect from an Android device

I'm still looking for a good answer myself! There are lots of possibilities but all have drawbacks from my perspective. I guess the 13" Onyx Boox sounds nice if you don't mind the cost. I haven't tried it though. Same with the 14" TCL Android tablet if you don't mind Android.
EInk gets expensive fast as the size gets bigger. At 10” its hard not to just use an lcd and bigger battery.

I don't like the fact that it has two displays. It's unnecessary and makes it thicker and heavier.
I like the concept. I have a e-ink reader where I removed the hull because it's annoying, but at some point I must have damaged the display a bit and now it has a little black spot. With this the added bulk also doubles the area available for text. Maybe not that useful for novels that you read through linearly, but for non-fiction it would be nice to see other chapters, glossaries, etc. on one display while keeping the other at the page you were reading. Mainly a problem of software and enough buttons to be able to comfortably use that.
Though the low-res displays of this prototype look atrocious to me (pixelation and uneven blackness), maybe a later version will improve on that.
How else would it recreate a book unless it had a folding display which would be even worse?
Books are made like this because it's impossible to make them any other way, but a digital device can have just one "page" since you read one page at time like Kindles and Kobos
The other option is a scroll. historicaly I'm told a book was always a scroll and the factor we now call a book was a codex. (I don't know how to verify this)
For some people, recreating the form factor of a book is the point, regardless of its convenience or cost. I'm sure whoever put this thing together was quite aware of how mainstream e-readers are built and didn't want that, or they would have bought a Kindle or a Kobo.
I can imagine a future device with an e-ink page that's so thin and flexible that it looks and feels like a paper book with magic changing text. I don't know how many consumers would pay a premium for that, but I would definitely buy my wife one.
Go old school and have it recreate a scroll. Really, not having to shift your head/eyes when reading is a plus with r-readers.
Nevermind the fact most readers and tablets come -with- a cover ... So its almost like a book anyway. Which people fold behind the page. Like a book. What was that extra screen doing again?
a cover ... Which people fold behind the page. Like a book.
Ho ho hold the fuck up

It’s too bad this isn’t actually “DIY”, because I have been mulling over building a dual screen e-ink sheet music reader for a while. Dual screens definitely have a place, it’s just niche.
Not a big fan of having 2 screens.
A huge fan of ESP32 DIY E-Reader!
Great. Now i can get that "real book feeling" of wrestling the books pages to lie flat enough for me to read them as I lay down.
The only reason I'd want 2 "pages" is so I could close it to protect the screen(s)... but that's exactly what covers are for.
Apart from the tiny minority of people who might prefer the form factor/"book feel", are there any actual advantages to having 2 screens for general reading?
Could also be useful for doing research with ebooks. Maybe show a list of bookmarks or the table of contents on one screen and the text on the other screen. Or you could compare different texts easier, showing one on one screen and one on the other. Or use one screen for notes. But I guess people that need to actually do productive research will use a desktop anyways.

It’s probably just for the people who want it. I have thought about how much nicer two pages would be in the past for this reason and for displaying sheet music.

I would like to be able to get comics and manga in ebook form. I’ve always had to go with the print versions because two-page spreads end up looking bad/being more confusing to read on my ereader thanks to the single page display.

Why not hundreds of screens so you can present all pages of a book at the same time and you just skip through the screen? Would be so much more convenient and innovative!
I'd get a whole bunch of these and keep a different book on each one, so you could just pick it up and read it. But it'll never work, it's too much trouble to keep them all charged.

Look. Hackaday... If it's a slow week... We get it. Take a day off. We still like you. Just... Less of this please.
oo we can bring back 2 page spreads, probably 2x price though.
