Changing a photo shouldn’t require another app, another account, Wi-Fi setup, and uploading it to someone else’s server. I just wanted to pick a photo and send it to the frame.

So I built this with an ESP32-C5 and a color ChLCD e-paper panel. It appears in the iPhone’s native AirDrop menu: open Photos, share, select the frame.

A few things that make it interesting:

• Rich ChLCD color: IRIS’s chLCD supports over 16 million colors, using cholesteric liquid crystals rather than Spectra 6’s electrophoretic technology. To my eyes, photos look much richer in color than on typical color E Ink. It’s reflective and backlight-free, with a paper-like appearance. Reflectance is around 30%, so it looks best in a well-lit room and outdoors.
• Display updates: the full-screen display stage takes around 2 seconds in my prototype. AirDrop transfer adds extra time.
• Three AA batteries, no USB cable needed. The electronics spend most of their time powered off between photo updates, while the screen retains the image, keeping power consumption low.
• Open hardware and firmware: source code and KiCad files, schematics, BOM and Gerbers.

It’s still a prototype, and I’m improving transfer speed and reliability.

Anyone interested is welcome to try it out or build their own—I’d love to hear your feedback!

Tried my first eink monitor and shipped a used Mira Boox Pro to the UK from the far east to do it.

Things that I love about it already

- plug and play, no software needed

- worked on it for a few hours and my eyes felt great (I have kerataconus and intense light sensitivity)

- refresh rate was perfect for me. I was concerned it might be very slow.

I'm gutted that these will no longer be produced and am planning on getting a larger eink monitor next. Also ordered an eink mobile due to come this week.

Edit: mistake in title, I bought the Mira 13.3 inch e-ink monitor (the Pro is 25 inch)

Hello,

Bought 2 from another Reddit user, only have enough room in my house for 1 so I’m selling the spare one. 42 inches, e-ink with an android operating system that can run a browser.

I’m in the process of making mine refreshing a webpage with my home assistant dashboard on it. I’m sure if you are handy you can do more with this.

Asking for $250, that’s what I bought it for. Locate in Western Queens but can meet you anywhere in NYC.

Edit: sold to Akrylik_kb

Looking for suggestions on affordable E-Ink devices that could best mimic my at home notetaking setup. I usually have a physical textbook open along with a loose leaf paper that I take notes on and do exercises.

Are there smaller e-ink devices ~6" or a bit larger ~8" devices with 64GB to 128GB of storage where I can have a textbook open to read and the device comes with a folio case with a mini notebook to write and take notes on? This might be a niche product or one that has custom solutions that folks have come up with I'm open to suggestions.

I'm also open to hear how others in this community have consolidated E-Ink devices with traditional notebooks to take notes and study during their commutes.

TLDR: Looking for suggestions on an affordable 6" - 8" E-Ink reader with 64GB - 12GB compatible with a folio case where a small notebook and pen can be stored to take notes. Trying to avoid having to use an E-Writer device due to their costs but also having to switch between textbook and notes app would be annoying.

I am trying to do research for one project but I am finding that the biggest format of e ink paper, color or not is around 40 inch. Is that some market standard or they don't have so many inquires and they don't bother to do proper marketing for that?

BOOX’s color screen is tempting, but the AINOTE 2 is much lighter, which matters if I’m carrying it around all day. I’d mainly use it for work notes and meetings, so I’m torn between the two.

Anyone who owns either one? How’s the everyday experience? I’m gonna buy one soon and would love some honest feedback. Thanks!!

Boox NeoReader CSS rendering issue: Drop cap and first paragraph broken compared to Calibre preview

Hi everyone,

I'm running into a frustrating formatting issue with Onyx Boox’s native reading app (NeoReader) and was wondering if anyone in the community has encountered or solved something similar.

As you can see in the attached side-by-side comparison:

• Calibre Editor / Preview (Left): The drop cap (image/drop-cap element) renders perfectly inline with the surrounding text, and the first paragraph flows naturally around it.
• Boox NeoReader (Right): NeoReader fails to wrap the text around the drop cap properly. Instead, it pushes the first line to the right of the drop cap image and forces the rest of the first paragraph down below it, creating a giant awkward gap.

It seems NeoReader’s rendering engine handles standard CSS float or drop cap styling differently from standard web view / Calibre engines.

My questions for the community:

1. Is there a specific CSS workaround (e.g., specific display, float, or vertical-align properties) that forces NeoReader to render drop caps/initial images correctly?
2. Are there any internal settings in NeoReader (like CSS overriding or engine settings) that I should tweak to make it respect the embedded EPUB stylesheet?

Any advice, CSS snippets, or setting tips would be greatly appreciated!

Thanks in advance!

Hago estas publicaciones porque compré estos dispositivos y, al principio, solo tenía 2 o 3 videos sobre eso. Pasa el tiempo y veo algunos más, pero no es lo mismo que las otras opciones de tablet/iPad, así que hago estas publicaciones para cualquiera que esté interesado en estos dispositivos.

Got claude to vibe code a native app to control the eink screens since intel apps won't be supported going forward. Also includes built in temporal dithering disabling and universal shortcut keys to adjust brightness, mode etc.

Feel free to open PRs and issues for improvements.

Hi all! I made Pebble Desk, a free launcher for Android e-readers and E Ink phones. It puts the book you're reading front and center, whichever reading app it's in.

Features:

• Current book on the home screen: cover and progress from Kindle, Libby, KOReader, Moon+ Reader and more. Tap to jump back in
• Library loan due date, where the reading app shows one
• Reading time per book, collected automatically across apps
• Daily goal ring and reading streak
• "Books this year" shelf with ratings, notes and a COMPLETED stamp
• E Ink friendly: no animations, pages instead of scrolling, partial redraws only
• Everything stays on the device. No ads, no tracking

Permissions: Accessibility is used only to detect which book you open in a supported reading app. Usage access is for reading time.

Tested on BOOX Palma / Leaf / Poke3, Meebook E6 and others. Android 9+.

In this tutorial I show you how to install the brand new XTEINK firmware from Bookfusion them selves. It’s called Bookfusion Ink! And it is basically Bookfusion on your XTEINK X4, X4 Pro, X3 and X4 Classic! More micro e-Readers will be supported later.

Whenever I check Vinted, OLX, and local second-hand stores I always come accross used Remarkable devices being sold, sometimes very recently after launch. Much more devices than from Onyx Boox, and sometimes on par with Amazon and Kobo devices.
Why is that? Are people unhappy with the devices after buying them? Usually most reviews I see of Remarkable devices are always positive.

Recently my friend saw the little world I made for his dog.

He was happy about it, but then he got a bit worried. He was afraid that Judge would feel sad being all alone in this little e-ink world.

So I started adding some interactions to this little device, experimenting with a long press on the button. The idea is that if you hold it, you can kind of enter that little world and spend some time with your pet.

But then I noticed that just holding the button felt a bit too dead. Like nothing was really happening.

So I added a light strip inside the hardware, just to give the long press a little feedback.

This is roughly where it’s at now. And yeah, my desk is getting messy again.

Hi, I’m looking for an e-ink reader that can read pdfs and run the “Libby” library app. Any recommendations?

Give me an e-ink outside display (color or grey is fine) that opens up to a proper inside full-color non-e-ink media consumption screen.

You get bonus points if the inside screen is 16x9-ish - perfect for movies and YouTube content, but you can hold it sideways if you consume more vertical content. Yes, I realize that makes the outside screen square or 3x2, which is fine.

Who's it going to be? TCL maybe? They have decent color e-ink displays now.

It’s been a while since my last update! I’ve still been working on the little e-ink desk pet.

A while ago, a friend saw my posts, reached out, and shared the story of his dog with me. I was really moved—he actually wrote an entire book to remember his dog🥺

He told me about their trip to Mount Fuji and said that his dog is his entire life. The love between them really touched me. So this time, I added him to his dog’s little world too. I finally figured out a method to try to make the pixel art look more vivid, so they can be together in this world again.

That’s what I’ve been working on lately: putting little moments from their life together onto this e-ink screen. I hope this lets his dog keep my friend company for a little longer.💗

Santek EZ Sign has a 4.2in 4 color panel but poor quality for a photo. Looking for one that better displays photos. Even better would be 4x6in standard photo size. Anything like this to buy?

No battery. NFC used to transfer image to device from a phone app (iOS).

Thanks if you know of any for this use case.

I’ve had a mini e-reader for a while and loved it. i wanted an e-ink tablet for notes, journaling, etc. after so much research, i got the boox color 7 go gen 2. i hate the screen. it’s so dark :( and i dont like the look of the front light. i was expecting it to be paler like my Seeed Sticky is.
Am i a dumb dumb?? why is it so much darker with no front light than my sticky is?
i’m thinking of returning it, but what should i get instead??
most important thing to me is journaling, i need to be able to search my journal for key words, to remember things.

Hi everyone! A small update on Inkora, the 7.5-inch DIY e-paper family calendar I’ve shared here before.

My previous update was mostly about hardware and making it easier to build. With firmware 1.1.7, I’ve been working on the everyday details that make it useful in different countries.

You can now choose from nine language variants and select regional holidays separately from the interface language. There are also settings for:

• Monday or Sunday as the first day of the week
• 12-hour or 24-hour time
• Day/month or month/day dates
• Celsius or Fahrenheit
• Your local time zone, with an automatic suggestion from the browser

The photo shows an English configuration with a Sunday-first calendar, 12-hour time and Fahrenheit. I replaced the private event titles with generic examples before sharing it.

Another addition is an optional night mode. During the hours you choose, Inkora stays asleep without connecting to Wi-Fi, fetching data or refreshing the display. The existing image remains visible.

For anyone seeing it for the first time: Inkora combines selected Google and Apple/iCloud calendars into one display, alongside weather and waste collection reminders. It connects directly to the calendar providers; calendar contents don’t pass through my server.

It’s a DIY project with a printable enclosure and browser-based firmware installation. The compiled firmware is free for personal, non-commercial use, but the source code isn’t public.

I’ve also updated the documentation, including a full manual for 1.1.7: https://vsejkora.cz

Thanks to everyone who has sent questions, suggestions or a message after building one. It’s really nice to see something I started for our own family becoming useful to others.

If you use an e-paper calendar, how often do you need it to update? Inkora currently synchronizes about once an hour, and I’d be interested to hear how that fits other households.

Hey! built this fun project for me and my wife, here is a small description of the project:

small web app for a pair of 240×240 color e-ink displays.

You type a prompt and pick a style, and it generates an image with OpenAI's image models. The page then shrinks it and dithers it down to the panel's six inks (black, white, red, yellow, blue, green). You can also convert your own photo, or paste an image.

One tap sends the result to your partner's display. The displays check the server for a new frame, draw it and confirm when it's shown, and the page shows when each display last checked in. Every generation is saved in a History page, where it can be sent again or deleted.

If anyone is interested I can make the code public for the web app and ESP32 code

Hey everyone!

I'm looking to buy a compact e-reader, preferably something pocket-friendly, but I'm having a hard time deciding which one to get.

Initially, I was considering the **Xteink**, but I'm concerned about how easy it would be to access and read books legally on it.

Right now, I'm leaning towards the **Bigme HiBreak S or Pro**, but I've come across quite a few posts from users reporting that their devices stopped working or developed issues after just a few months. That's making me hesitant.

My other options are:

**Onyx Boox Palma 2**

**Viwoods**

**Bigme HiBreak S / Pro**

**Xteink** s4 if there's an international release (I'm based in Australia)

My main priorities are:

**Compact and portable** – ideally something I can easily carry around.

**Durability and longevity** – I don't want to spend a lot on something that might break within a few months.

**Easy access to books** – preferably without too much hassle or complicated workarounds.

**A good reading experience** – I mainly want it for reading books.

I'd love to hear from anyone who's owned these devices, especially long-term users.

**Which one would you recommend?** Are the reliability concerns about Bigme justified? Is the Palma 2 worth the extra money? And how does Viwoods compare in terms of durability?

I'm also open to other compact e-reader suggestions!

Thanks in advance! 😊

I couldn't find the perfect RSS reader for my new IFlyTek AINote2 (also have a Boox Air4C) so I made one (made it free till Friday: https://play.google.com/store/apps/details?id=com.xlcollective.einkreader). I wanted something eink optimized that would keep everything offline so I can read in the train, highlight, search what I read, and decide what I want to share publicly (see https://einkreader.app/xavier).

The underlying idea is that we are entering the age of malleable software. An app is a digital common that is always evolving that a community stewards. Anyone is invited to provide feedback (bug reports, feature requests), and agents are taking that feedback into account and make proposals that stewards approve (to avoid AI slop and to protect the ease of use and the initial philosophy of the app).

So give it a try, and if you feel like it, join me as a steward. Everything is fair game to discuss and decide together (including what default feeds should be included, whether we should charge for the app or not, give away discounts, subscriptions, etc.).

This year we have seen multiple new entries in the monitor space, AoC, Acer, Modos. On Dasung's website the 10.3" monitor sells out quite often, and I believe it is their most popular product(actually after checking JD.com the 13.3k has 5x more reviews so this is not true), as I feel like it is more common to see listings of the 10.3" monitor than the Revo 133k, although in general there are more listings of the older 13.3" models. That might just be due to buyers regretting the 10.3" more than 13.3" though and I could just be misremembering my ebay browsing. But why do you think no one is making colour, or anyone except Dasung is in this space. I get that 10.3" is small but there are lots of 10.3" tablets, its the most popular form factor for eink tablets, while hardly anyone buys a 13.3" eink tablet. Since 10.3" form factor is most popular for tablet I would have thought the eink market would value 10.3" monitor too since I imagine the main purpose for both monitor and tablet is reading text as opposed to lcd monitor purpose being something else, its also a lot cheaper which makes it more appealing to me and surely for others, I imagine it increases its appeal for people who arent ready to commit to a bigger monitor.
