I bought a Kobo because it felt one of the most hackable e-readers but I ended up using the stock software with a single but very important change: I edited a configuration file to point the API to my BookLore instance.
This gives me access to all of my ebooks and preserves all the functionalities of the stock software, which is perfectly adequate for my needs.
It turns out that what I wanted all along was the ability to seamlessly read books I buy from any source, not any deeper hacking of the OS.
Kudos to Kobo for keeping their system so open. These days it’s not that common
Commenting to provide a confirming data point. I bought a Kobo Libra H2O a few years ago. Unboxed it, modified the config, and immediately started using it with Calibre. It has never participated in any manufacturer's "ecosystem" and has functioned well in a totally "offline" capacity.
I was sad to hear newer Kobo devices are shipping with Secure Boot. I've never reflashed my Libra H2O (it's my daughter's and I'd never be able to get it away from her long enough to replace it) but I liked knowing that I owned the device. I'm sad to hear the new ones are owner-hostile.
I used the Kobo with its ecosystem, even bought a few books with the store. Also disappointed to hear that they seemingly don't allow unlocking the bootloader on their newer devices... If that's true.
I don't care about secure boot / a locked bootloader so much as the ability to unlock it.
I'm not sure about that. The relevant discussion here is at https://news.ycombinator.com/item?id=46194337 but from the linked Github issue it's not at all clear that a true bootloader lock is involved. It should still be possible to boot something else on device, it's just likely to require a lot of work.
My dream for an open e-book reader is to have some kind of graphical OPDS browser as a substitute for the commercial storefronts offered by Amazon/Rakuten/etc. If you could host and publish your own ebook library (using BookLore or something similar), then explore and fetch content off of it with the same UI polish as you can get from a corporate vendor (complete with cover art galleries, carousels for recent releases and recommendations and the like), I think that'd make e-readers so much more appealing and usable for diehard FOSS folks.
I use koreader, including its OPDS server support! While I'm always grateful for all FOSS (and especially for well-written FOSS), koreader's OPDS UI still has a long way to go to approximate what I'm imagining. It's basically a file browser in List view, whereas a good digital book storefront would include gallery views with cover art, synopses and other metadata when clicking into any individual publication, search functionality, recommendation carousels, and more.
Yeah they could take some lessons from Plato. However, koreader works on everything. Android, Kindle, Kobo, PocketBook etc. Not just on Kobo like Plato does.
It took me some getting used to but it's not bad IMO. It's more that its conventions are a bit different from the commercial readers but that's not a bad thing.
True, that could be spiced up a lot. But I didn't think you intended it for mainstream users in your comment. For the HN crowd it should be enough. A mainstream user will not be messing around with OPDS servers anyway.
And recommendation caroussels are a bit too much like advertising to me. Something I wouldn't want on self-hosted stuff.
I'm desperately searching for an e-book reader and i wonder if someone here has a good answer. I'd like a something I can root and or at least run arbitrary userland code on. I want a size that's good for edc in a small backpack or handbag, maybe 7 - 11", pen support would also be really nice, does any such thing exist?
I got a Boox Go Color 7 as a less locked in alternative to my Kindle a while back, and overall I've really enjoyed it.
It's apparently rootable, although I haven't done that personally. It's Google Play certified so anything from the Play store works, and side loading Android apps works too. I use it with the open source KOReader app and in tandem with Calibre Web Automated. I did a writeup[0] with some details if you're interested.
I second this, been using an Onyx Boox tablet for a year and a half for uni. It's great for reading and taking notes and it fits nicely in my laptop bag on top of my laptop.
I habe a "Pocketbook Verse Pro" that runs Linux. No need to root, you can copy ARM executables to the SD card and run them (that's how I use Syncthing on it). KOReader also works on it.
Love my Remarkable 2, but my main use case for an e-reader is reading in bed at night, and it just doesn't work for that (form factor and lack of backlight, though the newer ones do have a backlight).
However, for reading technical docs or workshop docs in daylight, it's great.
The Kobo Libra Color is within your size range and has pen support. You can run Koreader on it and some other things, it's not like, a linux device though. I do think you can run arbitrary scripts through the program that manages alternative readers like Koreader or Plato.
I tend to think kindle is an anathema but I also think I'm heavily invested in their product, and so is a lot of the world.
Being able to strip drm is good. But, it's stepwise refinement warfare. In the meantime, being able to run a copy of the Google Android kindle reader, and obtain a valid licence-to-read key is useful. I'm not disparaging calibre or apprentice Alf, I'm just pointing out the more compliant path also exists.
That's what boox does. It's clear android can do this. I suppose what I'm asking is can these debian style OS run enough emulation/compatibility libraries to run an Android kindle app?
Don't the told exist to divest of one's 'ecosystem investment' in Amazon by way of Kindle. You've been able to strip DRM from the Amazon-purchased books and jailbreak the Kindle. At that point, Amazon holds nothing over you and both the ebooks and hardware are no longer held hostage.
I have a paperwhite theater I bought years ago from Woot for like $30 and I simply never logged in or even connected it to wifi, so I get no ads and I don't buy DRM-laden books from Amazon. Calibre turns DRM-free epubs into Kindle accepted mobi format seemlessly on upload.
I can't help but think that those who complain about the lock-in but simply never bother to break free, just don't care that much. Shaking a fist at Amazon feels more like a self-soothing exercise to allay the cognitive dissonance that arises from telling oneself that you agree with those who curse Amazon (or what it represents) while you continue to choose Amazon.
Unfortunately this is mostly for very old versions of Kobo e-readers! Specifically the ones that use an SD Card for internal storage. Very sad since I'm very much in the market for an e-Ink device that I can just use offline to read my .pdf and .epub files. Does anyone have suggestions?
Apparently they're working on a new OS based on the Pine64 Pinenote* but it's almost $400!
This is very timely, as I recently purchased a Kobo device. One painpoint has been syncing sideloaded books between my phone and Kobo. I am using Readest sync with KOReader but I'd love to see a more seamless solution. Hoping that Quill can offer some sort of sync in the future.
This is the best setup I've tried as well. Syncthing works so well I just often forget about it / take it for granted. I used to just deal with plugging our Kobo devices in, but now I can just distribute the relevant media by dropping a file somewhere.
The Kobo devices are truly worth every penny and we've got 4 of them in our household at this point. These are some of the best devices to put in the hands of kids.
Yes and Kavita just introduced support for it in epubs. It already had it for comics but that's because their pages are more static, a much easier problem to solve.
Considering the Kobo ereaders have bluetooth antennas, it is really too bad that they cant be put on the FindMy network to find a lost ebook. Open source firmware should enable that though since the FindMy protocol has been reverse engineered.
By OS I take it this includes a kernel and is a full replacement of the native Kobo OS (Nickel)? If so, then I wonder if it's possible to get Kobos to boot directly into KOReader.
While I do like Plato, it's got a lot of bugs and design issues... It can't handle epubs without chapters/really large chapters, it is noticeably worse on battery life than KOreader or the stock firmware, the amount of time taken to load the dictionary is proportional to the number of dictionaries, etc.
Is it? Calibre with deDRM is a must for me. I love Overdrive but cannot imagine to stick to the forced regime of lending periods and random waiting times. I also typically read multiple (sometimes dozens of) non-fiction books in parallel, plus one or two fiction. That just wouldn’t work at all with digital lending.
It's the only way that works with digital lending! If you want to always have something available to read you need to be steadily queuing up books, but then they come in at a semi-random time so you have to jump between books depending on lending periods / length / interest to get through everything you have checked out before they get returned.
I love the idea of OverDrive but I've yet to have success with it. Either the book I'm interested in isn't available or it's unavailable for weeks. I don't have a ton of time to read or to drop what I am reading when something becomes available, so I usually just wind up buying the book if I'm really excited about it.
Granted, my library is not part of a major city's system but it's also not what I'd call a small one. I'd be curious to know how NYC or Chicago compare, as those are where people I know have had very positive experiences with these options.
What works for me with overdrive is using holds and then when it comes available, if I'm not ready to read I let someone skip ahead of me. That way I'm still next in line but it gives me a few days until someone else finishes the book and then it pings me again.
If you read one book a quarter then yeah it’s not for you. If you read one book a week you can queue up fifty good books and wait for that one to come available at some point in the year.
If you care about the author, navigate to their website and buy a book directly from them, or a tshirt or something. Then they'll actually get paid, unlike from a library loan, or the scraps that Amazon gives them (unless the author depends on Amazon's print on demand for all prints of their books in which case, I guess buy it from Amazon).
> Waiting in line in a library app is annoying, but the waiting signals demand, which drives the library to buy more copies to circulate.
This is not true for digital libraries. They do not "buy more copies" to circulate. They don't physically send you an USB Stick with a copy of the book and you send that back without making a copy. They can send everyone "in line" as many copies as they want. Whats the size of an ebook these days? 1MB? How many trillion copies could you make in a day?
You have to wait in line to hopefully someday maybe be allowed to read a copy of a book while meta torrents a petabyte of books for their AI usage. This is nothing but a humiliation ritual.
Huh cool, we don't have any such large online libraries in Europe. Some countries or regions have some small online repos but it's a real PITA to get working as they all use Adobe drm.
I used to buy on kindle but since they made it much harder to break drm I just pirate now. I'm not paying for content I don't get to own.
I have an account with Berlin libraries and they offer both Libby and Overdrive (and some others) with a fairly large catalog. There is deDRM for calibre, and a command line tool called Knock which does not require Adobe software to remove the DRM.
But I don't think I will go back from what I'm doing now. It took a lot to get me to leave Amazon, but the DRM thing and also lately the larger amount of books "not available in your country or region" has just made me give up on the industry.
I will buy books now only if they are available to buy without DRM, and if they are not I will just pirate them.
What I don't really understand is why they've tied the reader app so tightly to the entire custom OS. It seems like it used to be more standalone, and these days that is essentially impossible?
I'd love to try this, but (tangential) have they fixed their screen issues? I sent back three Kobo Elipsa 2E units in a row before just getting my money back due to bright point spots on the lit-up screen, which are reportedly caused by dust caught between layers during assembly. It's a bit disappointing to spend over €400 on a device several times and discover that the manufacturer apparently can't even bother assembling them in a clean room to avoid messing up the primary feature of the device.
Rakuten, the company behind kobo, has always tolerated hacking their devices, so there are several options, including KOReader, Plato and the subject here, Quill. Personally I think Kobo is your best option, if i understand your ‘open OS’ requirement.
It turns out that what I wanted all along was the ability to seamlessly read books I buy from any source, not any deeper hacking of the OS.
Kudos to Kobo for keeping their system so open. These days it’s not that common
There is a config file on the stock OS that you just need to change, and you can point the Kobo store to your own instance of Calibre Web.
This lets you sync and download your own books to the device over wifi.
I played around with KOReader a bit but found the stock software simpler to use. All I really need is to not be tied to an ebook store.
I was sad to hear newer Kobo devices are shipping with Secure Boot. I've never reflashed my Libra H2O (it's my daughter's and I'd never be able to get it away from her long enough to replace it) but I liked knowing that I owned the device. I'm sad to hear the new ones are owner-hostile.
A quick config change to the store URL to point to Calibre Web, and some setup in Calibre Web and you're good to go.
This is the guide I followed: https://brandonjkessler.com/technology/2021/04/26/setup-kobo...
I don't care about secure boot / a locked bootloader so much as the ability to unlock it.

The Remarkable 2 has an e-ink display but is rather underpowered as an e-reader. It does have an SDK for building apps: https://developer.remarkable.com/documentation/sdk

Does anyone know what the mainline support is like nowadays, and whether widely packaged software can make it usable as an ebook reader?
0. https://github.com/Quill-OS/quill
https://git.sr.ht/~hrdl/linux/log/v6.17-rc5_pinenote has many commits.

Until you learn the hard way that e-ink displays have a thin, fragile glass plate inside.
Integration with libraries is the killer feature of ereaders IMO
Granted, my library is not part of a major city's system but it's also not what I'd call a small one. I'd be curious to know how NYC or Chicago compare, as those are where people I know have had very positive experiences with these options.
In the end I gave up and just download now.

Part of the motivation derived from newer Kobos deploying with SecureBoot, making it tough to reflash them.
