Open Book: 2023

This is a beautiful project. Everything about it is what I wish manufacturers would copy, even a fraction.

[@geometerfpv2804]

Uh...so only supporting plaintext and not having any navigation? What exactly is it that you want them to copy? This is clearly a hobby project. Manufacturers make consumer products.

[@tomprice5496]

From a marketing and data collection point of view, this product is a total disaster. Companies want you to be the product, not the ebook.

[@bazoo513]

A _very_ laudable project - thank you, people! Just a note on file format: File formats were never an obstacle to e-reader interoperability - DRM is. Plain UTF-8 text should be displayable on this device, of course. But expanding it to HTML, markdown etc would be a laudable endeavour. Yes, plain text content is 95% or more of the value in a typical piece of literature (perhaps little less in textbooks and such), but adding features such as cross-references, index, TOC etc would not be too difficult. Perhaps even dictionary lookup, using some of free dictionary databases in a format that will enable enthusiast to contribute their own. EPUB is ISO standardized open format (ISO/IEC TS 30135) and no company controls it. It is less complex than it appears at the first glance, and supporting it, too, should not be a huge undertaking - there are tons of free EPUB reader apps for all possible platforms - perhaps one in marvelous open source tool "Calibre" could be used as a template for developing one for this device. Expanding the software driving this device in this way would remove _any_ advantage the proprietary ones have over it.

[@alsomika]

Considering it's open source, it'd be cool to see someone add epub compatibility

[@cupuacu4life13]

What the fuck is laudable

[@Markyparky56]

I agree; you lose a lot of intentional formatting by going plain text. If epub is a platform independent standard it would make sense to support and promote it.

[@EraYaN]

EPUB is probably the way to go, it supports images and such as well which are crucial for quite some nicely formatted EPUB and comic can be made to work with epub as well, although cbz and cbr are more common and less fussy.

[@colbyboucher6391]

What I don't really understand (and this is only vaguely related) is why we don't have a standard for zipping up simple HTML / CSS / JS websites for offline use. It shouldn't be all that hard, and yet our options are either to have a bunch of loose files, or... Electron. EPUB is basically proof that it's possible but it gets a bad rap because publishers are lazy as hell and tend to make awful EPUBs even though, like you said, it's not a very complicated format. It's just a markdown language. It's 80% HTML.

[@ManuelSLaraBisch]

So this looks like a very nice idea and pretty well thought through in its execution, especially for a homemade project. However, I think that if it *only* supports plaintext files, that'll probably be too big of a compromise for many readers. Even if they're willing to accept a lack of illustrations on the cover and inside the book (a big if), there are still readability considerations such as having page breaks before a new chapter, footnotes and end notes, larger font sizes and center alignment for headings, italics and bold text for emphasis, etc. Also, I suspect people these days expect some navigation features from an e-book reader, such as being able to jump to a specific chapter from the table of contents, or from one chapter to the next. I've personally used these extensively when looking up recipes in an EPUB-formatted cookbook.

[@so-tz8lp]

you said it. my kindle has a bunch more features and capability and works out of the box. its just a tool that works better. the spirit of this project rocks though

[@DerMBen]

Agreed. I really love the both the concept and execution of this project, but as it exists now, it's so limited. Luckily EPUB is an open standard and there's nothing stopping a future open source ereader from supporting it (maybe even a continuation of this one). The higher requirements might increase material costs, but I'm optimistic.

[@DavidLindes]

@@DerMBen Agreed; here's hoping this is a successful project at least to the level of being a springboard for more open/libre designs and software in this space.

[@maximkovalkov1334]

well i guess an alternative firmware could be developed that supports all those features! that’s supposed to be the advantage of having an open and accessible design :)

[@ManuelSLaraBisch]

@@t0k4m4k7 In principle I agree, but it also depends on whether the platform's hardware would support more advanced layout processing without unacceptable tradeoffs in lag/battery life or not. I'd love to see some planning stage documentation of what features would be desired vs what could be achieved without more expensive hardware.

[@naktaal]

This looks like a great project! Those buttons are a little on the small side, though. I also agree that EPUB support would take it to the next level. Keep it up, though. There definitely needs to be more competition in that space and an open source option would be great.

[@Chad48309]

The button problem could be fixed with a better housing design, and the introduction of large caps or supported bars.

[@Cobalt985]

You could slightly change the design and 3d print bigger buttons to go over them

[@sarowie]

@@Cobalt985 you are right, but this is the trade off of opensource hardware: Either go bigger/thicker (which is unattractive) or use smd buttons without cap (which is awkward to use). 3D printing just is not injection molding. But there is a trick: most EBooks and Smartphones life in a protective case. By marrying protective case and product case, the product can become a brick like the Nokia 3310.

[@anacajustories]

I never understood why going after what you want to see or read was so hard on those streaming platforms. I'm trully tired of all those barriers preventing us from what was the main reason for the internet: connections without walls. It makes me happy to see that there are other people thinking about ease and openness for everyone, if I were in the United States, I would certainly find a way to join you

[@DoubleMonoLR]

Indeed, all providers of digital content really need to be transparently available via an open standard web interface(& file format) - likewise with movies etc. Digital content availability is a complete shambles, caused almost entirely by wilfully proprietary standards and devices, it's ridiculous. Ideally governments would step in to enforce, but there seems bugger all chance of that happening. It's particularly ridiculous in the supposedly environmentally aware age, where devices are simultaneously incapable of using content from numerous providers &/or are permanently incapable of doing basically anything useful once the company decides to kill off a device/service.

[@dannymundo7538]

With the kindle you can just hook it up to a computer and move the book on to it. I have never even had it connected to the internet or spent a single cent on any amazon books.

[@colbyboucher6391]

Simple, money. Personally, I think people should just recognize that in a world where the internet exists a LOT of traditional business models become unusable, rather than enforcing traditional business models with garbage DRM, but that's what's happened. Being an author isn't something that can make you money in a truly free market where information is freely distributable. (I also wish the general public would recognize that and pay authors anyways, but so it goes.).

[@マキ-i1n]

@@dannymundo7538 true, I do the same, there are so many mobi and epub version of book out there, that you can transfer with Calibre eBook, but still i hope that project keeps on going !

[@theburntcrumpet8371]

I was onboard until you suggested that .txt is the one book format that will stand the test of time. I'd actively want to use this if it supported epub. Although I guess the magic is that it's open source, somebody can add epub support.

[@oienu]

I know, i don't know if my ESP32 can unzip the file, maybe I need one having PSRAM to try :,D, but we really need the epub format or rtf at least. I can have notes on txt but trying to read a book there will be a mess x.x

[@sarowie]

@@oienu if in doubt, host software can convert/preprocess any format into an other format. SD-Card storage is cheap. if in doubt, splinting the book in to pages and storing the pages uncompressed should reduce RAM requirements and processing times.

[@mrsvcd]

Epub is too heavy for esp32, my experience is that it is too heavy for my phone. My idea to solve this would be a ebook targeting version of markdown as a first step and a openbook targeting folder structure for ebooks with picture support and other things needed as a second step (using ebook md as the text base).

[@oienu]

@@sarowie or we can keep epub format but change to zip no compression, this will need add an extra step to use the file, since mostly they are compressed, but zip can store the file to keep all unify and you can read the content independly.

[@wearr_]

I love this project, and when possible id love to build one myself, but the most major turnoff is of course lack of EPUB (or even PDF) support, and seemingly not very rich navigation features (ie. specifying page number to jump to) It would be doable in theory, and im sure in future revisions or community modifications, they'll get sorted through and added.

[@eg1do]

This is an awesome project. This should be at high schools as a course project. This way every student would have an ereader, they would learn the other side of tech, the side of openness and control over their devices and software; and those devices would be made by themselves, so they could repair them, expand them... Even if someone is not really interested in tech, being alien to it is a luxury we can't afford anymore.

[@StrikingCrayon]

You should take this to Futo. This is brilliant. And they'd likely pay you well to bring it to reality. I'd to love see this in an injected molded mass-market good.

And, as someone else mentioned, epub is an ISO standard and anyone can use it completely for free.

[@cristianoo2]

​@@shawnsorbom8907we could increase the computing power, spending a little more money and then running epub. It's better than txt for sure, as epub is already established as a chosen format. Epub or mobi. I'm not sure which one is lighter

You could also just use it as an external display this way. I hope it being open source will lead to these ideas becoming reality.

Looking forward that such a firmware update so I can get right into building! :)

[@sethstenzel]

It needs to be able to display images as well. I think you need this to allow something like markdown or a markup language, as well as a format that will let you have a standard (or several) page sizes of texts so that there can be some forward caching. It also looks to me like there could be room for larger through-hole components, easier for new makers. I'd also like to see AAA size used instead of double for a lower profile, even if that means using 4x instead of 2x.

[@kezif]

Version of the project in github uses aaa batteries, so its okay on that side. I didnt watched the video yet, but it seems like book uses raspberrypi as mainboard and proprietary text format for displaying. It kinda odd for me because its cuts a lot of functions (Im real fan of kindle’s search, notes, time to read and send to device via cloud functions. But it’s raspberry so software wise it could be upgraded to your needs by community. (image, pdf display, etc.)

"I think you need this to allow something like markdown or a markup language" EPUB. EPUB is a standardized markup language designed specifically for ebooks and it's much better than it's poor reputation suggests.

@@colbyboucher6391rather than cross compatibility, I'd rather see optimizations made for this specific device, with just "good enough" features to cover your bases. I would rather a conversion be done on an epub, that optimizes that format specifically for this device, to allow for a crisp UI and reading experience. Now maybe that means have both options, accept a slower epub, and accept a customized format.

Wow someone actually made this a real thing! I have this same idea of using esp32 and reused kindle e paper because of how cheap it was, but I'm just an amateur and I don't know how to reverse engineer the displays. I also kinda imagined it to have 2 displays running just like a book and that's the beauty of open source, anyone can modify and customize it. A lot of people complained about the .txt only format but this is actually what I need. And epub format would be nice but someone could probably add that feature if they wanted to. This year hackaday really is amazing. Great job!

[@PainterVierax]

thing is: you don't have to reverse engineer the display of an old Kindle. If you search online you'll find this has already be done by previous projects using ESP32 as the display controller (I wish I could remember the name of the github project I'm thinking of, sorry ). Other than that, Kindle can be jailbroken and the whole hardware surrounding the display gives you way more possibilities than the ESP32.
