E-ink is so Retropunk
rmkit.dev
rmkit.dev
rmkit is a library (and group of devs) for creating apps on the rM (and now Kobo). outside of rmkit, people typically use Qt to write apps, but there's many routes[0], including SAS[1]: a solution that uses unix pipes. the rM2 requires a bit more hacking to get working than the rM1 because their framebuffer driver[2] is embedded in their software for rM2 and requires updating rm2fb every time remarkable releases a new update. there's alternative drivers[3] to drive the display in development.
i will keep updating the article based on feedback, thank you and keep hacking

as long as you have SSH keys and you don't blow away your home partition, you are mostly fine. you do need a slightly older version of Xochitl, though (3.2 and below)
It would be nice if someone were to start working on an aftermarket linux distribution/ecossytem that targets eink devices. It's a lot of work to do, though, so I'm not surprised that nobody has picked up that torch yet.
Some notes on the reMarkable, it is running a custom linux distribution that is based on Openembedded Core[0]. The company publishes their modifications to the linux kernel[1], so one person has created their own linux distribution for the original reMarkable tablet [2]. The reMarkable 2 currently has no native framebuffer driver for the screen, due to it being software controlled by the UI application, which requires a workaround for custom applications[3].

That is what I'm trying to do with https://github.com/bjesus/air . Kobo runs mainline Linux quite fine, and specifically PostmarketOS works great. Assembling an interface that plays nicely with the device hasn't actually been that difficult!
1. You can either just serve an image on a URL and the device will display it, refreshing whenever the image changes:
https://www.invisible-computers.com/invisible-calendar/image...
2. Or you go one step further and wrap it into an API with a settings page, which will also allow others to install and use your app:
https://github.com/Invisible-Computers/image-gallery/blob/ma...
To be fully transparent: I know that many people are using the first approach to display their own designs, but I haven't had much uptake yet on the second option to build a public, installable app. So if anyone is interested in trying this out, please contact me! I am willing to cooperate closely and iterate on the API where necessary.
(I hope that this is sufficiently relevant, even though I am tooting my own horn here.)
https://github.com/Invisible-Computers/image-gallery/blob/ma...
But right now, I understand that building an app for my platform is
a) more hassle than just pointing to a URL
b) limited upside, because the audience that you can charge for a subscription isn't very big yet.
However, I think that a good app could generate its own audience (aka drive ppl to buy the displays) and then make money by charging them a small monthly subscription fee.
- You stop updating the app and my phone OS wont run it,
- My phone stops updating its OS and cant run the app, or
- The walled garden gates lock shut on you for whatever reason and I cant install the app, or
- You stop supporting my version of the display.
Is there any way to interact with the display without the companion app? Pushing raw bytes over the network is fine, just anything that doesn't require some phone.
In another eye rolling move, I also dont really consider a response of "we promise to opensource the companion app, or unlock the device if we go out of business" viable (what if you die unexpectedly?, or simply, dont care to follow through?).
If the promise is real, they should make it legally binding. If you go bankrupt, you lose control over your IP and quite possibly can't choose to follow through.
Although, even then, open-sourcing the app can be expensive (you need lawyers to confirm you actually have the rights to open-source all parts of the relevant code, and if there's something you can't open-source then you need devs to write a shim, identify the relevant keys that need to be published, and hopefully write some documentation.
I’d like to see legislation requiring this for any software that a physical device needs in order to work, but I doubt that will happen any time soon. (“Right to repair” is meaningless without something at least as strong as source code escrow)
I think your questions are valid and not eye-rolling at all.
As for the app, you can find the Android APK here, so as long as you have or find an old Android device, you can sideload it anytime: https://drive.google.com/file/d/1nnAHVm21FLKIAJ4kTmz6Q0D9Zk4...
But there is another dependency that you haven't mentioned: The device requires a running backend with an API.
At the moment, my only answer to that is: "I'll keep it running even if it becomes uneconomical and I will then also open-source everything.".
But I am also intending to add a way to completely avoid the backend, which will require users to render the data in a specific format to the device.
Supporting this is totally worth the effort for me. If only to put my own mind at ease a bit! But, and there I have to be honest, I have limited resources to work on things. There are other features that I feel are very pressing as well. And so I cannot promise when I will find the time to implement this.
Honestly; a (?rest?) API to push content and trigger updates would potentially cause me to buy immediately if I can self host all the required parts. I've been trying to come up with a household GTD system for awhile now and i can see some clean integrations.
What if the device had a mode to let people connect to an API via a lan connection? That would solve all the privacy issues I just mentioned, and also improve reliability when the internet is flaky. It would also solve the e-waste problem if your backend shuts down.
The config would point to the API that a user can deploy. Exposing more knobs through a config would be much easier than through a mobile app.
Overall, I am impressed with the device and the dev-friendly documentatio. I consider buying it. My use case would be to display weather and calendar - preferably together. The OAuth2 stuff is quite complex, so I appreciate that the company handles it on the backend.
Does that just require some hacking, or do they still some how lock that down even if you are a power user?
Just remember to ensure you have some form of recovery prepared or make the necessary pogo connector just in case.
Just back from a reading session in my Kobo, and I sent this article to it of course :) (through Firefox/Pocket). I can even read in the swimming pool (it's water resistant), nothing better than reading in sunglasses halfway in on a sunny day, awesome!!! And it doesn't weigh as much as some books. While I still prefer paper for certain reads, it has definitely helped get back into the habit of reading real books/reading more, so lost to smartphones and social media / "sugar" information type content these days. So convenient in terms of size/weight/number of books you can carry, while being easy on the eyes. No distracting crap, either, as TFA mentions.
Long live e-ink, whatever device you like most!!
i’m always worried it’s just around the corner from outliving its usefulness/profitability to most people. even within my tech/gadget bubble it still feels like a relatively niche thing. this keeps me upgrading my Kindle pretty much anytime a new one comes out because i’m always worried the technology will be discarded. i really love the fact that i can fall asleep reading on it pretty naturally. this DOES NOT happen when i’m in bed on my phone or tablet. i’m glad to see devices like reMarkable and Scribe pushing it further, and i just hope research continues to get the tech to a point where it can refresh quickly without artifacting at near lcd quality. and yeah, it’s nice to have a device where i physically can’t distract myself with inane social media or other silly things. i’m generally of the Alton Brown thought that anything uni-task is unnecessary, but i’ll continue to make a happy exception here.
I'd probably buy one immediately if I could be guaranteed I could put any pdf on it and have it display flawlessly, and if it were relatively open in terms of compatibility.
That means an e-ink device the size of the pages. So probably A4. A device of 21x30cm. (8.2x11.7inches). That is huge. Equivalent of the largest iPad.
In a world of uni-task devices, that is one worth owning.
So I find books with Libby, check them out, then hit sync on the Kobo and they all show up. It’s brilliant. I used to torrent books and now I never do, I just borrow from the library constantly, and I love how having to make choices (because not everything is always available) widens the scope of what I’ll try reading.
I've already had my eye on Kobo, but Libby support seals the deal I think.
Which Kobo do you have?
In terms of Libby support, keep in mind that the method I am talking about doesn't depend on any interaction between the Kobo and Libby. I think it's all based on Overdrive, that is, I check books out from the library, and the Kobo knows what I have checked out and syncs anything that isn't on the device already. My kids have newer Kobos and this method works well for them too, so you should be good.
YES I am aware there are ways to hook an e-ink screen to my laptop. But that's such a kludge! How is it that there are so few options, how is it nobody is thinking about the health benefits of knowledge workers being able to spend half their day in the sun?
Sorry for the rant, it's just big tech brain that very few product developers think in this way. Humans are meant to be outside in the fresh air and sunshine, not locked to a damn screen all day.
I would be SO happy to sit outside and think and code for many hours without worrying on battery life.
No need for a powerful CPU. I just need to edit my code, see if it works and take notes.
I want to hack on my compiler while the cows graze around me !
this isn't a hardware product (people here have mentioned an e-ink tablet that can sideload, that plus a keyboard plus a battery, or ESP32-S3 etc) but rather a software product.
and that software is the glorious resurrection of vt320/vt330 buffered/paged terminals. because that's what's going to minimize your terminal's power consumption. you need to brutally minimize the number of bytes you transmit, which means having relatively small working set for any assist features (eg things like debugging might be nicer with a local variable cache). A large persistent eMMC or flash storage (but optimized for doing some decent writes) might be nice for those things. 32GB or 64GB goes a long way in a dumb-terminal context, you can use that like a portion of your RAM load if you code carefully.
btle can do some active data transmission in realtime and it has the basic "beacon, I'm still here" etc, and you can use the notification-push thing for server-side async ops. And ideally you'd use your phone as a BTLE client that routes packets/data or provides your server-side api. This can be done even on apple with the Bluetooth Browser thingy, your self-hosted website can interact with your BT device and that'll be your relay.
https://en.wikipedia.org/wiki/Bluetooth_Low_Energy#Applicati...
in an interactive scenario with an IDE-ish thing and a larger working set maybe you use more power but if you're running a nano/pico clone onboard that's dirt simple and can be done with simple buffer flush etc. And most of the ESP32-S3s come with 8MB of external SRAM.
The other major power draw is the USB, I think you could bring that down a lot with an actual hardware circuit wired right to the ESP32.
Again like, the e-ink tablet with an external KB is simple and lets you get tinkering with the editing experience in that kind of form factor! but I also think you can cut power way below that if you use something like the ESP32-S3 and BTLE with aggressive onboard caching. Don't forget to minimize power in idledown mode, and idledown as aggressively as possible. Running the keyboard as an interrupt-driven thing could cut power a lot if you can idle down between keypresses.
Part of the success of things like GPUs is their ability to degrade gracefully in the presence of one or two errors which would otherwise render the whole thing unusable.
Better than cutting edge semiconductor fabs? Why would LCDs need such cleanroom facilities?
Also, CPU manufacturing facilities keep the insides of the machines cleaner than the facility, containing the wafers in transit between machines, and LCD manufacturers do not have the same luxury.
I mean, I'm not saying they aren't, I just don't know. And the explanation you're presenting as the likely reason doesn't really bear that out. So far anyway. :)
I think you're expecting some sort of first-principles argument as to why that ought to be true (or worse, asking someone to waste a bunch of time digging up a public citation on the details of factory design), which you're not going to get handed to you on a silver platter. To put it bluntly, if you want to think about it from first principles, go for it, it's not that hard. If you want a source for something covered under NDAs, you can go do the work yourself.
This is most tenable for large-scale displays (e.g., wall displays), and we're already used to segmented "television walls" in which borders between individual displays is strongly evident. The trick would be for such compound devices to both match one another's display characteristics (brightness / shading / hue), and for borders to be made as undetectable as possible (several possible mechanisms suggest themselves to me as I write this).
Given the sweet spot of 8--10" displays, compound devices made of multiples of these would seem to be at least a conceptual possibility. 16x8 displays would give 32" diagonal measure, 300 dpi, and assuming 50% BOM cost might run less than the 25" Onxy BOOX Mira Pro ($1,750).
It's a shame that this technology is kept artifically out of reach to hobbyists.
I've seen the Waveshare displays, but they're too small and limited in features (monochrome or few colors, very high refresh rate, etc.).
This is still an issue where a single company controls the entire tech, right? When do the relevant patents expire?
Some exceptions are obviously inapplicable here, e.g. special rules for plant varieties [1] and nuclear energy [2]. The one most likely to apply to e-ink displays is that, under the Bayh-Dole act, if an invention was funded by government grants, and the patent holder fails to make it widely available, the government has so-called "march-in rights" to license it to third parties themselves. However this has never been successfully used. Wikipedia summarizes: "Though this right is, in theory, quite powerful, it has not proven so in terms of its practical application" [3].
[1] Perhaps because it's controversial to allow plant varieties to be patented in the first place, the statute for them has an explicit compulsory license clause (see the last subsection): https://www.law.cornell.edu/uscode/text/7/chapter-57/subchap...
[2] https://www.law.cornell.edu/uscode/text/42/2183
[3] https://en.wikipedia.org/wiki/Bayh%E2%80%93Dole_Act#Petition...
I mean, someone can also compel you to license your IP using a hammer.
Newer versions that are easier to manufacture or have color are still under patents for a while.
The answer would be "chiplets" of course, assembling bigger screens out of smaller ones. At the hobby leven, I think something decent could be built out of a few second hand kindle screens, if you plan the seams as part of the aesthetic.
Aside from the ink capsules and higher voltage (though still very low), E ink is almost identical to LCD and probably slightly easier to make. There's a TFT (which can have a larger footprint, since it doesn't need to be transparent) on the back, an LC or E ink capsule layer, and an ITO electrode. Dead pixels are almost always caused by damage or defects in the TFT.
I wouldn't say it's artificially out of reach, though- setting a line up to produce large panels is a high opportunity cost. If anything is artificial about it, it's that you presumably can't buy E ink capsules yourself. With enough effort you might be able to separate the top glass from an LCD TV, dissolve the LC, and replace it with E ink, but I have no idea how you'd do that. No promises it wouldn't burn out the TFT immediately.
False. E-ink film, especially color, is definitely more complex to get right than LCDs. Sure, e-ink displays have the same TFT layer underneath just like LCD displays, but the e-ink pigment and film is tricky to make.
TFT: Thin-film transistor
LC: Liquid crystal
ITO: Indium-tin oxide
LCD: Liquid crystal display (though this one's widely known).
(Please expand acronyms on first use. Even, or especially, where they strike you as well-known or obvious.)
This Is Not A Popular Habit Here On HN
But it should be
YMMV
(Not the hero we need, but the hero we deserve.)
I went with a 7.5 inch display for the eink calendar / smart display that I am selling.
I am definitely feeling the limitations, but there is still a lot you can do at that size.
Have a look: https://shop.invisible-computers.com/products/invisible-cale...
And maybe once the business grows, I’ll have the volumes needed to get better prices on the bigger displays.
I’d buy one in a heartbeat if there was support for iCalendar or other common/open standards.
If you write me a short mail at info@invisible-computers.com and tell me what integration you need, I will make sure to let you know once it is out.
In the meantime, there are often ways to sync other calendars (also iCalendar) with google calendar. It’s a bit of a detour but it might just work.
Showing a clock ended up being bad for the display as it quickly degenerated. You calendar view is great.
I’m looking into 10 inch displays right now, but they are already significantly more expensive.
At some point it just drives the price of the end product up too much.
<https://onyxboox.com/boox_mirapro>
Note that the pixel density is markedly lower than other e-ink devices. For smaller devices, e.g., the Poke 5, DPI is more than double at 300 dpi (comparable to a laser printer): 6", E Ink Carta Plus, 16 shades of grey, 1072 × 1448 dots, pixel density - 300 ppi
<https://onyxboox.com/boox_poke5>
Granted: with increased viewing distance, resolution can fall somewhat, but given that areal density falls as the, well, square, this is 4x lower resolution.
The Mira Pro runs an eye-watering $1,750, further impeding the viewing experience. Given price trends on other E-Ink devices, I'm pretty sure that's all but entirely driven by the display cost itself.
If you want I can let you know once it’s done if you send me a short email to info@invisible-computers.com
I can send you the disassembly instructions (email me at info@invisible-computers.com) and then you can disassemble it before painting.
Or if you want I can paint it for you, but I would have to charge a bit extra :)

Would strongly recommend using another language than PHP to make it work, but the LLM du jour would probably translate it to any other language for you.
Here was the original post that inspired that one: https://onezero.medium.com/the-morning-paper-revisited-35b40...
Thank you for learning English! As a speaker of (to some extent) 3 other languages, I for one appreciate anyone who has struggled to learn English as an (N+1)th language.
When they first appeared, I was sure the price would drop with increasing volumes, but that has not happened. Probably they can't get good enough yield, and it's not a product suitable to sell with dead pixels, like a TV, where cheap models have dead pixels while the premium models don't.
It sounds like they might have just recently expired but I imagine there is a catchup phase.
E-ink is expensive because it's a niche product that lacks economy of scale, and it's a niche product because it does almost nothing that can't be done by LCDs (which are incredibly flexible). E-ink is amazing, but it doesn't have the best business case.
I assume that's why its first killer app has been pricetags. A store with 5000 items each requiring a LCD pricetag would be constantly replacing little batteries or having to reprogram units if they popped out of a plug or rail-basewd power system.
I think some of the interest from the hobbyist brows is less about that and more about other aspects of the technology-- it has a bit of a distinct look and excellent full-sun readability.
A hypothetical nonbacklit high res grayscale LCD would have some similar properties and might be more viable at small scale; I know they're making basically that in small sizes for use in resin 3D printers.
Errr, not really. LCD price tags existed before e-ink (and still do) and battery life was not much worse. It's something like 1.5x-2x tops, so enough to make business sense, but not orders of magnitudes earth shattering as one might assume.
Not necessarily that. They're making the switch to digital price tags because it's much quicker and easier to run promos on certain items to clear the shelves before closing time on perishable goods, but most importantly, they're making the switch because when employee have to manually change paper price tags, mistakes happen far too often, and stores end up in situations where the price on the self doesn't match the price on the cash register, angering customers who in certain jurisdictions are entitled to compensation for the store's pricing mistake.
Digital price tags ensure such mistakes are gone saving the store money over time.
E-ink is great, but it is niche and basically everything that you can do with an EPD, you can do with an LCD. E-ink screens are in the at best tens of millions, whereas LCDs are in the billions per quarter - there are over 6 billion smartphone owners in the world already, and LCDs are in everything from supermarket self-checkout kiosks to laptops to smart fridges, they utterly demolish E-Ink in scale.
I love e-ink screens, but there's no denying the tech's business-case is rather marginal and that won't change anytime soon.
The commenter said that a billion dollars are needed to make the technology scale but The EInk Corporation itself raised only 1/10th of that and now they're making a billion dollars per year off it -- why haven't they brought prices down then?
If you look at their annual reports, EInk sure seems to think their patents are important; they mention patents as part of their "strategic roadmap" every year. Their initial patents were in the late 90s, and the last few years the royalty revenue amounts on E Ink's revenue breakdowns have been dropping every single year as they shift more and more into actually making the screens. The data lines up IMO.
Now, while €120 isn't nothing, it's also not a whole lot, and it's cheap enough that with a few books a year you're saving money.
Amazon's 6" Kindle sells for €110 by the way, but is missing some features my Pocketbook has, and the 6.8" Kindle Paperwhite with comparable features sells for €170. Doesn't seem that much cheaper to me.
They even have a pi version
This is a myth. They're not artificially expensive, they just have low economy of scale because they're a niche product. As you yourself said, you're tempted to just buy a large LCD display instead.
Is that fundamental to the technology, or is it just it being a low-volume niche product?
I make and sell an eink calendar (and smart display) for $149, complete with mobile apps and google calendar sync.
https://shop.invisible-computers.com/products/invisible-cale...
The display is 7.5 inch.
This is still a side project for me though I am thinking of ways to turn this into a self-sustaining business.
A battery adds a lot of complexity and cost for testing, certification and shipping. And it adds another failure mode. So I decided against it for the current version.
I’ve got my Urbit running on a native planet hardware box (https://martiancomputing.substack.com/p/product-review-nativ...) plugged into my router’s switch that I can access from anywhere. The UI for groups also looks good on e-ink (mostly white and black, nice design) one of the devs has an e-ink phone that shows it off. It’s cool to really own the entire stack.
I had the original remarkable tablet mentioned in the post and it was really cool (someone was also using it as a browser to access urbit back then), the new tablet looks better too.
There was someone at the first urbit assembly (probably here on HN) working on cool new e-ink style tech that had some advantages without having to engage with all the patent nonsense and vendor lock-in that has plagued (imo seriously stalled) e-ink as a technology.
This is the first time I'm hearing about Urbit and, having spent the past 5-10 minutes browsing their website(s), I still haven't been able to figure out what it is exactly. Could you explain? And what do you use it for?
I primarily use it today for chat (similar to IRC), and I locally host my own system. Every user is their own server.
I wrote up a longer form description here: https://zalberico.com/essay/2022/09/28/tlon-urbit-computing-...
Hopefully that’s helpful. It’s a little outdated now though. We’re doing free hosting for now at tlon.io to help the network grow (so it’s easy to check it out).
The (long) original technical intro to the ideas is here: http://moronlab.blogspot.com/2010/01/urbit-functional-progra...
Just kidding. Seems like a brilliant collection of ideas.
Maybe some "slow" strategy game, that updates upon certain events but might remain unmodified for hours at a time? Or - more in general - an application that is required to be on for a long time but really doesnt' change often.
The biggest roadblock to these being super compelling is update rate. The black/white screen on Badger can be driven pretty hard, but overdriving it (a friend built a continuous E-ink zoetrope [3]) has consequences.
Inky Frame’s 7 colour display is awesome for dithered artwork (missing cyan and magenta notwithstanding) but very, very slow to refresh- ~30s after the panels were updated to incorporate an unskippable “clean” phase.
Faster, cheaper and bigger all seem mutually exclusive right now, but I share the authors passion for the format.

Doing a write up has been a plan of mine for a while now lol I bought a 3d printer to move on from the gutted airpods box and a case has been in a half printed state just waiting for me to design the rest of it. I've run into a creative wall and haven't gotten much further.
Hacking on a panel scrounged from a discontinued product, or a bare one, sure. But when you're spending multiple hundreds of dollars for a new part, I don't consider that the hacker realm.
Nothing against the author; I've been looking at E-ink for a long time and this page is inspiring. But in the end, the cost turns me away yet again. Also the pitiful refresh rates I've seen...
Kindle is probably not the best choice for DRM free books since ePub and PDF are the dominant formats (outside of Amazon).
I run it with ESPHome connected to Home Assistant.
Fits in a picture, I only update it every 8 hours. Battery is still alive after two months.
I'm using Todoist to host a Todo list that I can update from my phone. It gets pushed to the eInk display on my office wall.
(I am trying to sell an epaper smart screen as a commercial product. Right now it only has a calendar app and I am looking for apps that I can add.)
I’d hack my own but I’m a little paranoid of bricking it with only one hardware button.
https://www.youtube.com/watch?v=xJIS_amo7TI
I think he used a boox tho
Plus, the ReMarkable 1 has a total of four hardware buttons, and is even 50g lighter! Plus it's power button doesn't get stuck.
Unfortunately the Folio keyboard doesn’t work with it. So it’s stuck being a tablet.
I tried this but latency with the cursor was annoying for me, so I just did termux with tmux so I can be keyboard-only.
I'm working on an e-ink theme for Obsidian[1]. So far it's working on Boox devices, but I wish I could get it running on reMarkable. I'm not as clued into the reMarkable ecosystem, does anyone know if they will eventually add an app store or better tools for developers?
The idea I want to eventually pursue is set up a service where you could sync your pdf (or send specific pages via email), have them OCRed (including dates and titles specifically since they already live in well-defined parts of the pages), and then ingest them into your PKM for long-term storage and recall
Unfortunately Obsidian Cloud doesn't seem to have an API to support this at present, but I think it's theoretically feasible with Notion at least. Let me know if you build something like this :)
The screen I am using doesn’t have touch input though, so it would only make sense if your app has non-interactive use cases.
For now, the only out-of-the-box app that my display comes with is a calendar with google calendar sync. I am looking for ways to extend that.
Maybe email me? (Email is in my profile.)
And here is the eink smart screen I am talking about: https://invisible-computers.com/
This is a myth endlessly repeated without evidence. LCDs have patents up the wazoo (OLEDs etc, plenty of new screen techs), it didn't stop them being developed. E-Ink just doesn't ha e any economy of scale, and it hasn't had an easy route toward economy of scale in the future, it's fairly niche in it's use-cases when it's competing with LCDs.
If ReMarkable ever adds an app store, I'll eat my RM2*. They suffer from Apple syndrome and it goes against their "digital paper" schtick.
*No I won't.
Yeah, their whole product management is just downright obnoxious. Personally, I'm waiting for Supernote to open up their devices to 3rd-party devs.
The language is one of the nicer Pascal descendents. The windowing system was similar to tiling. The entire system was tiny in terms of code. Everything was black and white.
One of the nicest features was universally embeddable widgets. You could make a simple clock and embed it in running text, for example. Kind of like what OpenDoc dreamed of, or Google Wave's inline widgets, or what it might be like if you could extend Discord with custom UI in a few hundred lines of code.
I wasn't motivated to keep using Oberon—it was honestly too odd and too small to compete with my other desktop options.
But I do agree it would be neat to try with an eInk display. It's a small, interesting, black-and-white system with a minimalist UI. Particularly if you customized the UI input layer, it could be a neat tool for building small household dashboards.
This said remarkable 2 is so underpowered it's impractical. I love the paper-like experience, but I never use it for any important notes because I can't find anything ever. For example copying and pasting more than a trivial amount can take minutes (i.e. it blocks for minutes) and scrolling is just painful. Writing is not always accurate and you can get weirdly thick lines, etc. All of this can be fixed with better hardware and more performance, but I suspect the experience vs cost ratio is logarithmic/exponential.
While scribbling in Goodnotes an iPad pro is not as "rewarding", actually working is so much better.

I tried out the color boox and to me, it looked like the worst of eink and lcd. Bad colors, bad battery life, hard on the eyes, slow, and expensive.
A week-long battery life, cellular connectivity, visibility in the sunlight, and it should be cheap if it’s cost+ priced.
Oh the things I’d put on it. I could host an API on my server where I’d ask GPT to summarise recent events or my email metadata and calendar events. I could probably finally ditch my smartphone for good.
Its hard to find anything like that, though.
This seems like there should be good ways for a) easy sync and b) OCR without relying on their subscription (that's required, no?).
Idk about hackability and whatnot but as far as a useful e-reader, note book, sketchbook, planner, it’s amazing.
Edit: Also unaffiliated with this product but it’s awesome: https://hyperpaper.me/
Configurable, highly linked PDF planner with a very responsive person behind it (I figure he must be around here somewhere :))
I recommend pairing it w/ a LAMY stylus.

You can currently "sideload" apps. It's not officially supported but the Supernote team appear to appreciate people tinkering. Adding an official means of installing apps has been in the road map for a while.
> You guys are really exploring! A kind warning, installing third-party apps on your device may cause problems, as our kernel is optimized for E-Ink screens. We cannot guarantee a good experience with third-party apps if they are installed through unofficial methods. We are in the process of adding an official app store and support for sideloading, so please kindly wait.

Hey, that's me :D
Thanks for the shout-out Ethan, I'm happy to answer any questions people have about hyperpaper
https://support.remarkable.com/s/article/Help documents where to find the information, and the account details you are given afaik are for root
Probably because it's easy to get root, like another poster mentioned.
I use it pretty much daily for reading, and occasionally for all sorts of hacking fun.
It's really a shame...
I've been using a Boox device lately to read old comics and I LOVE it. https://shop.boox.com/products/novaairc
The thing is that it makes them feel so retro because of the limited colors they can supply, and it still looks great doing it.
My only regret isn't a regret, it's just timing. I purchased the nova air c before the Tab Ultra C had come out. https://shop.boox.com/products/tabultrac
And its form factor is just so much more pleasant.
I can't wait for the coming years of e-ink advancements.
Imagine an open ecosystem whereby we can have low power embedded systems running Linux OS or RTOS for plethora of computing/sensing/IoT useful applications on top low cost MPU that need rudimentary or sophisticated GUI e.g. dashboard, virtual buttons,etc [1].

I'm not saying this isn't "retropunk" - it's probably a complex mash of the two meanings of the word "punk", in reality. I do hope you push for the latter meaning, however :)
One from Waveshare, a 10 inch display that I cannot seem to get a current rev data sheet for:
https://www.waveshare.com/product/displays/e-paper/10.3inch-...
I really want to run it via USB and understand the controller better. Currently using SPI on a Pi 400.
And a smaller one, Papirus. I have that one on a Pi hat and have gotten quite a ways with it in python.
Love these things and agree with OP on their appeal.
It's fantastic, as it has a big battery for all-day battery life, and the display is eminently sunlight-readable. It's just a little bit of a bummer that it's tricky to ensure elements always contrast well against the map with the greyscale colour-scheme.
This has not been my experience with ARM assembly. There are several RISC machines with far smaller and simpler instruction counts.
The standard open ISA RISC-V can be described like that relative to both legacy ISAs.
The latest release handles most things without locking.
I got my 3 MMOs working on it (Java, Java+LWJGL and C+), the impressive part is both OpenGL 1 and OpenGL ES 3 work as expected, but much too slow still.
Raspberry 4 and Vision Five 2 are the contenders for relatively open and passively cooled 100% gaming.
Even if the TH1250 and RK3588 promise more juice they also consume ~10W and make more heat that in most cases require fan or very large heat sink.
to anyone considering buying one, if you are left-hand dominant, skip it. what most people don't understand is that being a lefty doesn't mean that you can use a mirror image of what's served to righties (in this case, the UI) and then everything is fine.
don't get me wrong, I'm returning it for several reasons - a few can be inferred from other people's comments here. I'm only putting this out there for all my sinister siblings, 'cause writing english is a pain for us.
Also, the Remarkable devs are notoriously bad when it comes to software updates and sharing their plans for the future with the community. Meanwhile, the Supernote people even share their Trello boards over on Reddit -> https://Reddit.com/r/Supernote
The Supernote, admittedly, is not as hackable yet as the Remarkable but 1) official software updates are much more frequent and 2) there are plans to open up the device to 3rd-party Android apps.
But kindle is The cheapest e-ink afaik
Edit: I also experimented with the Poke 3 by creating a sort of "writerdeck" setup with a bluetooth keyboard and termux, then attaching everything together with velcro and magnets: https://chuck.is/writerdeck/
it uses grayscale bmps that i create through calibre so fonts are great and i dump in a sd card that goes in the display. the esp just manages the sleep of the display and the displaying the correct image. with the battery switch that i have, it can last months
So it would be the same basic principle here as what you envision.. boot into that other system, but have it instead launch some other app.
Too bad. There are probably other use cases for "keep the screen on continuously".
> It's kind of finicky as well: I would have the network selector pop-up and stay there if there was a temporary disconnection in the WiFi (say if someone used the microwave).
Now this I've never seen. The WiFi is pretty solid here, though... there are 5 WAPs in different parts of the house (primarily so I can get signal out to the edge of the yard -- the house is only medium-sized)..

My dream is a pocket computer running headless linux with a reasonable keyboard, e-ink display, and vim/mutt/git.
I feel like my eyes have gotten really tired from over a decade working in the tech industry, and wondering if taking my notes/reading emails/articles on a reMarkable 2 or similar could give my eyes some rest.
I've fucked with Gentoo and Arch for so long that sometimes I just want a break from it all. No dependency hell, no bugs, esoteric stack traces, nor popups, advertisements, notifications, nor distractions. Just some pen and paper, except without the eraser shavings or ink blots. Not having to scan your notes to digitize them is a nice bonus as well.
Especially since the pandemic and in the WFH era it's nice to get away from the omnipresent touchscreen or mouse and keyboard interfaces and deal with something a little more tactile; something reminiscent of a less perpetually online era. I'm tired of being hyperconnected to everything. Not to mention all the problems from staring at LED monitors all day long.
Sometimes I don't want to troubleshoot software; I've done enough of that already.
But it's great knowing that I _could_ drop down a layer at any time. It makes me feel a lot more comfortable about relying on an ecosystem to know that it has redundancy in the support layer. For example, if Remarkable themselves go out of business, will I still have access to my documents? Will they still receive updates? Will I still be able to buy replacement parts?
Both Linux installs were an 'it just works experience'.
The windows box has been a total pain in the ass and I've had to reinstall multiple times.
Linux is a better out of the box experience than Windows.
Excepting 4k, which is fine out of the box. the pain comes in if you need fractional scaling.
I started using Gentoo on my personal machines (Desktop, Laptop, NAS) after I needed to understand it for work. Eventually I fell in love with the developer workflow that it allows.
That was seven years ago. These days I feel like I've spent so much time tinkering for little to no benefit. I've been through LFS a few times so I don't feel that being a Gentoo user made me understand Linux any more than I already did.
So much "emerge --sync && emerge -1 sys-apps/portage && emerge -auUDN @world" and then fix USE flags problems and mask problems and keep rerunning the last command until it actually works.
I somewhat self host everything right now - VPN into my home network to access my NAS. But the user experience of documents and media just feels so poor compared to existing cloud services that I'm tempted to just give up on homelab stuff.
The upfront price of 10+ TB hard drives is hundreds of dollars a drive, you need to replace them every 5 years or so to "trust" them, you need redundant disks because you can never trust them, you need a backup solution, time investment to make backups, and the price of power in the Bay Area means you are spending several hundred a year on power to run the gear. Whereas I could just get 10 TB for $50/month from a cloud provider. It's not like I actually watch or listen to any of the blurays or music rips I've made, which represent most of my data...
I bought a PineNote in early 2022 hoping to replace my reMarkable. I've worn out the battery but I don't want to give money to a company that intentionally makes swapping the battery nearly impossible. Along with the fact they're useless at work because you can't directly use a cloud service, you have to proxy through reMarkable's own service.
I thought it'd be fun to tinker on but then I actually developed a healthy social life and exercise routine again and have found little motivation to stay inside when I'm not working.
Personally I completely agree with you, and could have written almost exactly that paragraph - I too have a ReMarkable (the 2nd / current version), and love using it as it ships for both note taking and especially for reading ebooks/PDFs ("especially" just because it's what I use it for more, not because that's what it's better at - in fact, its UI for reading documents is among its weaker points and I hope they improve it in future software updates).
However it is worth pointing out that you can SSH into it, and there are a fair few 3rd party tools and hacks for it - so far I've avoided trying any of them as there's nothing that I want strongly enough to have even a 1% risk of bricking it to worry about. But I'm tempted to start playing around with it someday.
This is the best list of stuff for the ReMarkable that I'm aware of, though I don't know how complete it is / how many released tools or guides there might be that aren't included here:
Not sure what problems you mean. Any reference?
That's why I switched to FreeBSD.
Every OS kernel update, every package upgrade just works. Rock Solid.
OT, but FYI... I have all that on NixOS. Things install and run reliably and configurations stick reliably, all declaratively. It feels like "the final distro hop" for me.
1) Getting back to known-good from any fucking-with that breaks something is 1 rollback away.
2) It's still Nix wizardry to do something as relatively simple as set up a systemd background process that gongs on the hour (I actually made this work, but it broke recently and I don't know why yet because 2-year-old-son). This actually discourages "distracted hacking" while making you work for the changes you definitely want, which ends up being a nice compromise.
FWIW, I've been the most productive on this Linux distro of all the ones I've tried (Ubuntu, ElementaryOS, Pop_OS, Manjaro, Arch).
It's the same trick that pharmaceutical companies use to extend their patents. Find a slightly new use or way that also covers the old use, and bam, exclusivity for another 20 years.
This effect in the case of eInk is clearly described by others in this thread.
The real problem is that E-Ink is a niche product that lacks economy of scale, because LCDs do everything an EPD can do and more.
I don't know if it's been patented, but E-Ink's recent Gallery 3 screen is pretty amazing, they got multi-dye color screens to refresh fast enough to use in an e-note. That's insane, that's an order of magnitude reduction! It might actually make color e-notes a viable product category.
That's a bit disingenuous and short-sighted view from people not knowing or understanding the industry, market, technology and manufacturing challenges. Sure, like any successful tech company, e-ink owns patents and controls a large part of the market more-or-less, but patents aren't the main reasons why the e-paper industry hasn't moved forward.
That's kind of like saying "ASML's and Cymer's patents are the reason the EUV lithography hasn't moved forward and why they have no competition."
No mate, that's not true. Just like EUV lithography, making e-ink tech displays, affordably, and at scale with good yields and healthy margins to keep the industry afloat, is hard, very hard, bordering on magic, which is the main reason they have no competition.
Turns out making minuscule pigment electrostatic particles that can quicky move around inside a fluid suspension and hold their position long enough at various ambient conditions, is a huge challenge, and manufacturing that at scale with very low defects and sustainable margins is even harder.
Nothing in their patents currently is holding back competition, but competition can't reach the scale and yields that would make enough profits to support a viable competitor consider even entering this field, versus OLED displays, as that's where thew real money is in display manufacturing right now and that's where the competition is heating up and where all the R&D money gets poured.
That's why there's been various alternatives to e-ink-like tech popping up from university research labs and being displayed at trade shows, but going from a research lab one-off prototype being shown at trade shows, to mass production at scale with good yields and profit margins, is the real challenge and is where e-ink has their secret sauce that nobody can successfully replicate.
Similarly how China has been showing off working home grown Xnm lithography prototype chips that can compete with TSMC, but reaching the yields and volumes of TSMC is where the impossible to cross cliff lies, and why people get confused and don't understand that the major challenge lies in manufacturing at scale and not just the core tech that makes the widget unique.
I'm not defending e-ink the company and their corporate practices, just wanted to shed some light on the technicalities of the subject and hopefully clear some of the FUD and conspiracies that get wrongfully spread around.
For clarification -- disingenuous is defined as:
> not candid or sincere, typically by pretending that one knows less about something than one really does
In your post, are you claiming there's a shadowy group of people who at the same time are both unknowledgeable but also conspiring to hide their own knowledge?
>In your post, are you claiming there's a shadowy group of people who at the same time are both unknowledgeable but also conspiring to hide their own knowledge?
No, that's nowhere near close to what I claimed. I think my post was clear on what I meant despite my mistake: that people are too quick to blame e-ink the company for malice without understanding the technical challenges around industrialization of such technology and the economic factors of the e-ink-like products market (profit margins, supply/demand) that drive competition and investments, or lack thereof, in this tech.
Also, I have no reason to apologies to the commenter as he did not provide any evidence to support his claims that "e-ink is evil" in order for his integrity to be affected, to warrant an apology for my counter-arguments, nor do I think the original commenter is petty enough to be offended by my honest mistake, which I rectified later.
to me, that counts as a reason to apologize
> Sorry, I'm not a native English speaker. "disingenuous " was the wrong word in that context. I meant to use it as a synonym for "unfair" and made a mistake.
This particular mistake (assuming disingenuous means a little less than it does) is not particularly uncommon among native english speakers (or on HN, at that).
FWIW:
> you called them a liar who was pretending to be stupid
The "pretending to be stupid" is not an essential part of the definition above (merely "typically by").
Finally, Merriam-Webster offers up other definitions:
lacking in candor
giving a false appearance of simple frankness
These don't fit particularly with the strident definition you're using.
English words are complex, with contextual and flexible meanings. You've picked one definition. And then you've attacked someone's integrity on the basis of it, which is exactly what you're arguing has been done to someone else. Don't be this guy.
You're on the right track, though; it's worth asking if the people criticizing patents and their stranglehold on innovation are not being candid or sincere in doing so. (The answer IMO is "no, they're being very candid and sincere, in stark contrast to most defenders of contemporary patent law", but it's nonetheless the more relevant question).
It doesn't really make sense to say that on the one hand, it's super tough and hard to make a profit, and on the other hand the costs of accessing patented hardware is an immaterial cost.
Your post just really isn't convincing that a patent here has little effect on the ability for others to compete.
When margins are as tight as you say they are then obviously the costs of licensing are going to make the margins even thinner or next to impossible for another competitor to meet.
Love when people come out here with unironic defense here of monopolies by simply defending them as some meritocratic output of success or something.
That wasn't my point. You must have misunderstood.
But ideally, even if you think they don't deserve your explanation, considering it's a public forum you could still explain why you think there wrong for the benefit of the rest of us who maybe also don't understand your argument.
That wasn't snark from my end, I was just telling him he was wrong, as plead for him to re-read my comment again with an open mind. That's it. Actual snark would have added more fuel to his flame-bait which I didn't want to do.
> considering it's a public forum you could still explain why you think there wrong for the benefit of the rest of us who maybe also don't understand your argument
Because I don't have more information than that of my original comment, which is based on some years of experience developing products with e-ink displays and getting to know the tech and the company to a degree that allows me to have a relatively informed opinion to a degree on this topic.
And, because you can never please everyone no matter what you do, and some members can be overly contrarian and needlessly pedantic at times when it contradicts their entrenched belief that "evil corp is evil", expecting "sauce or GTFO" for every opinion on the matter (even though they themselves provided no proof for their "evil corp is evil" opinion), but I don't have or can't publicly share any documents to provide proof or more deep insight into the matter, nor the time to perform investigative journalism on the spot based on public OSS data, just to win an argument here.
Like I said, it's just my opinion based on my experience in the field, so take it as is with a pinch of salt, as an opinion of an average joe on the internet, not as a proper journalistic piece.
I'm just finishing up Schnier's - A Hacker's Mind - and it's a good example of where "hacking" happens these days. The force the book profiled hackers are working against are just the masses. Us. People. Which has always been around - but it makes me wonder if we as hackers of the 80s and 90s just developed a mental toolkit for corporations to use against us and then left our counterculture post empty.
Is there evidence of this? On every HN e-ink thread this is repeated as if it is common knowledge, but I haven't read much to back it up. Have you personally been shut down by lawyers when you try to use an eink display in a hacker kind-of-way?
And yes, there are patents, but so what? How does the company wield them? Are the licensing terms terrible? My Raspberry Pi has a Broadcom CPU. Broadcom is no stranger to patents yet there's plenty of hobbyist and hacker activity around their components.
1. Does not make any logistic sense: eInk is rather a small company versus the likes of Qualcomm, Sony, Sharp, Fujitsu, Philips, Microsoft (thanks to Wacom) all of which have way more patents in the EPD area that eInk. EPDs are literally as old as the _GUI_, and even started at the same place (Xerox). Plus, eInk relies mostly on chinese manufacture... which is well-known to generally don't give a damn.
2. Could not possibly have any motive: eInk apparently is a suicidal company that likes to torpedo its already shrinking little market so that .... what exactly? LCD manufacturers have a field day?
3. Ignores the fact that there are, indeed, multiple competitors to eInk whose panels are either indistinguishable from eInk or literally better. Many smartwatches like Pebble/Garmin don't use eInk _at all_, yet people even right here in HN still believe they are eInk. Qualcomm of all companies (an actual patent troll -- ask Apple -- and most definitely unlikely to be afraid of a minuscule company like eInk) owns a in my opinion _much_ better EPD technology called Mirasol which has zero of the slow refresh problems of eInk, much better color reproduction, much better contrast *, and is barely more expensive!
The plain truth is that majority of customers just don't care enough about these technologies, and therefore they will always be niche. At the end of the day, average customer can't distinguish the latest EPD panel to a reflective LCD from decades ago. Customers will flock towards shiny glossy LCD watch over EPD all the time. That's why Gyricon failed. That's why Mirasol failed. That's why every other electrophoretic startup folds.
* eInk contrast is still a joke and for the last decade actually degrading rather than improving, thanks to touchscreen layers, color filter layers, etc. But you see it being parroted all the time that "eink has infinite contrast". The latest color panels this year are no better than the ones I have on WindowsCE devices from the late 1990s, eInk or not. Colors still look incredibly dull, there is a ridiculously limited palette, and resolution and contrast take a sharp hit (pun not intended).
Does the author know who wrote DOS? Microsoft and Apple were essencial to the magic of that era of computing.
It’s a genuine question, someone born in the 2000s is 23 now and will have only experienced that age indirectly.
Hint: it wasn't Microsoft!
Edit: to clarify, when people say "DOS", 99.999% of the time they mean MS-DOS, not the generic "disk operating system", which is a category and wasn't developed by anyone in particular.
The “DOS for the 2020s” being anti-Microsoft and Apple makes no sense to me. Also, DOS was the mainstream, not some retro-cyberpunk thing. Again, makes no sense at all to me.
In addition to that, lending ebooks from the public library provides (at least some) income to the e-book authors and editors.
The library also has the current (clickbait-free) print versions of newspapers as e-papers, which the shadow libraries (at least those that I know) have not.
They synergize very well, though. :)
My go-to e-reader for years has been an ad-supported kindle that I immediately jailbreak to install KOReader and remove the ads (as well as any communication with amazon). It's cheap, supports epub, and the hardware is surprisingly good and durable.
As a bonus you can basically install any GTK app you care to on there; I have a term emulator with SSH and a chess game with AI on mine, for example
Also, developing your own OS is not necessarily cheaper than porting Android. Boox has been doing Android-based e-readers for a long time and their devices are usually on the cheaper end for the hardware. I feel it boils down more to UX rather than cost - do you want to let the user install whatever apps they want, or do you want to give them a more curated experience (and probably also limit them to your walled garden).
I know you can de-DRM Kindle books, but there are other walled gardens that don't allow you to do that easily (for me it's some Chinese e-book apps).
Performance is always in tension with price and weight, but software openness isn't in tension with any of them, really.
Yeah if you discount the one huge and obvious advantage of this approach it’s not clear why anyone would do it.
The thing that nobody realizes until they actually spend some real time with eating is how much more comfortable it is to read with then a phone or iPad screen. It works in all lighting conditions, the battery life lasts for weeks. Good luck reading on your phone at the beach on a sunny day.
The things that it's not good at are non-text based games and videos, but that's not what it's for. I have a computer and phone for those things.
But I could imagine sitting this on my desk and using it when designing software to draw out diagrams.
That said, I also use actual paper and pencil and have notebooks full of sketches... so ultimately I don't know if I would want this or not.
Help me decide!
EDIT: I bought it so from here forward only rationalize my decision that it was good!
The only benefit imo is portability and ease of sharing to computer, but I find my scanner on my printer works perfectly fine and that I have trouble finding things digitally even with effort organizing
My opinion against e-paper tablets would definitely change if their price becomes much lower
It managed to get close enough in feel (not perfect to be fair) to paper that I don’t mind using it for notes and studying.
It’s pretty nice being able to markup text books and research papers as a separate layer I can toggle to de-deface the page, add note pages, etc. And having my whole book collection at hand everywhere I go without lugging around a 50lb backpack.
I still prefer paper for desk references. Flipping through a 300pg tome looking for a specific familiar page is still easier with analogue.
That’s my 50 cents :)
I have a supernote. I'm glad I have it, it fills a niche for me that has been very beneficial. With that said, I don't think because it works for me that it will be a good tool for everyone. I'll make a bit of a blunt argument, but I hope you take it in good spirit.
If you buy some shiny new toy that you know you don't need then you are a slave to your desires, a slave to marketers. You're taking hard earned money that could be saved, invested, or donated and using it to engage in a useless fantasy of some sort of benefit that you already know to be marginal. Do you want to be the kind of person who does that? Do you want to be someone who mindlessly consumes products just for the sake of consuming products? Tools are a means to an end, don't make them an end in and of themselves.
Also, you already have a workflow. What are the costs of switching from what you know works? Think also of possible unforeseeable downsides. You know the limitations of what you have currently, but you also know /exactly/ what you have. Do you choose the unknown item that will only possibly have marginal benefit or do you stick with what is tried and true, known, and established? Id choose the established option any day of the week.
The very fiber of my being down to my DNA is about creative energy, not consumption. I am inspired by tactile things, and things which spur certain energies. This is why I love programming, painting, etc.
Money is no issue, so there's that.
And lastly, my entire mind is a kaleidoscope of tradeoff decisions every waking second. Things like "investing the money of my tablet" I will just never do. I do not think like that. If I can have a happiness factor of 10, with the ultimate cost of not investing as some variable, and the amount of time learning about investing, and the benefit of the joy of learning things that earn me far more than investing, or starting a new company, I will always simply choose the simple answer "Just earn more." That is ultimately what it always boils down to, with my happiness and satisfaction level of life at the highest, while minimizing costs of heavy minutiae like investing. It's not that I don't like technical things, I am obsessed with them, but I can have hundred percent returns through my own companies rather than < 10% returns through investing. I'm absolutely certain this will seem like the 'wrong' perspective to others, but no one else lives in my head. For me, what is most paramount, is that I'm constantly maximizing benefits while minimizing costs, and projecting this plan forward constantly, and refining my trajectory if I see inefficiencies, or miscalculations.
Also "literally no purpose for it" is hyperbole, I obviously have some purpose for it or I wouldn't buy it. I have 20+ sketchbooks sitting next to me that I fill, and every new project or company I start/take part in which is complex, I sketch it out across multitudes of pages. I was more saying that... I have no "need" for it to replace paper, but I'm always open to trying new things that augment my experience
Paper is better for reading than E-ink.
I then switched to an Entourage eDGe briefly (too big) and then to an Entourage eDGe Pocket in ~2011. I still have it and use it (battery amazingly holds all day charge under use).
Just got a Boox Tab Ultra C and I am in heaven. The CFA layer over the eink goves really nice muted colors that remind me of 1960s news print and it is so easy on the eyes. The screen refresh speeds are amazing (I actually watch videos using PiP floating (smaller windows refresh better) while doing other things. The Android 11 install is heavily optimized and runs beautifully. If I use it for just tectual data in airplane mode I easy get nearly a month per charge.
My dream is a laptop that is 300+ DPI eink @ 13-15" with maybe a clear oled overlay for when you need color. It would be so nice. Or even a laptop with a rotate screen like the old panasonic toughbooks or fujitsu lifebooks that has a 180 hinge.
Oled or IPS hiDPI on one side and highres eink on the other.
Would be phenomenal. As soon as I have the spare cash I am going to get one of the desktop eink monitors! I am so excited they are finally becoming a thing.
I used to run a greyscale NeXT Turbo for years. Was only 68hz but it was a proper monochrome CRT and was easy on my eyes. For whatever reason, color CRTs hurt my eyes unless they are ~85hz or higher.
Anyways, enough ranting. Suffice to say eink is a dream for people like me and I can only hope it contonues getting better <3
It seems people managed to jailbreak older versions but you will brick your device if it's too new...
As for bricking your device: It will not hard brick, it may only soft-brick[0], as in, the display will not update on the rM2, because the software driving the screen needs to be updated to support the new OS. You can still SSH in and revert the changes and then downgrade. If you were silly enough not to write down your SSH password, or set up an SSH key and can't get into SSH, you can still recover your device[3] on your own.

This big warning is on the front page:
> Warning: Toltec does not support OS builds newer than 2.15.1.1189. You will soft-brick your device if you install before support is released. See remarkable2-recovery for information on how to recover your device if you have done this.
There are two types of bricking[0]. A hard brick, where the device no longer functions, and may not be recoverable, and a soft brick, where the device is still working, but fails to boot to a usable state.
> It does NOT sound like having root access.
Could you clarify what you mean by this not sounding like you have root access? You have the ability to sign in to the device as the root user out of the box, which is exactly what root access is.
> This big warning is on the front page: > > > Warning: Toltec does not support OS builds newer than 2.15.1.1189. You will soft-brick your device if you install before support is released. See remarkable2-recovery for information on how to recover your device if you have done this.
Yes, I know about the warning, I wrote it. When it was less strongly worded, way too many people were ignoring the warning, trying to install toltec on an OS version that didn't have the offsets required for rm2fb yet, and did not write down their SSH password or set up an SSH key.
Interesting. This means that if I ruin my grub I soft bricked the PC. As long as it's recoverable easily, I wouldn't consider that 'bricking'.
> Could you clarify what you mean by this not sounding like you have root access?
I just meant that if the device is no longer usable, you don't control it (as root). But you clarified that soft-brick is like a boot problem which, if easily fixable, isn't a problem.
> Yes, I know about the warning, I wrote it.
Heh, small world.
/s
Very fun piece.
QBasic would be fine. GW-BASIC would be fine. P5.js would be great. Hypercard would be adequate. Heck, even raw assembly code would work.
Documentation on jailbreaks, microcontroller versions, ssh, and file systems? Not so much.
The whole point was /simplicity/. Simplicity isn't the same as ease-of-use or speed-of-use, but old-school computers might boot into a BASIC interpreter. That was simple.
I'd love to have a simple eink solution. I don't care if I'm manually flipping pixels or have high-level APIs, and I don't care if I'm using BASIC, Makecode, Python, or C. I do care that it just works, and I know ahead of time it just works.
What I don't want is I buy an old Kobo on eBay, and find out it's not jailbreakable, or requires some library which requires a different version of Ubuntu, or whatnot. I don't need another half-baked project.
The actual ultimate here would be an all-in-one which is micro:bit compatible. All-in-one means it includes a case, a reasonable form factor, and works in standard micro:bit programming environments.
Why does it have to be /simple/ anyway? With a rich programming environment you can make your own simplicity. The world needs more devices that force you to come to them, not the other way around.
Yours is probably a better one, but perhaps less relevant here.
I understand what you're getting at. When I was following some of the article links with respect to the Remarkable 2, I had the exact same concerns when they were discussing how you need to wait for the patches to be updated to new firmware versions since the screen driver was integrated into the software. Needless to say, I have also been bitten by such things with other devices.
That said, you picked a poor example. Kobos aren't locked down in any meaningful way. Anyone with a knowledge of Unix and how the update process works can inject their own software. There are no secrets. There is no encryption. At least when it comes to the operating system. It is the way hardware should be, albeit it is so rare for it to be so that it is easy to jump to conclusions.
EDIT: misread, I agree
And that's obvious.
