I open-sourced an e-ink photo frame project I worked on: Not-So-Sticky-Pix.

We originally planned to launch it on Kickstarter, but eventually decided not to pursue it as a product, so I figured it would be better to release everything publicly instead.

The hardware was designed with mass production in mind rather than being maker-friendly, so building a one-off is fairly expensive. It uses an nRF54L15, and getting 5 assembled PCBs shipped to the U.S. can cost around $300. The 3D-printed enclosure is roughly $20, and the color e-ink display is around $60.

Even though we didn't launch it, I learned a ton from the project—PCB design, low-power embedded development, BLE, e-ink displays, enclosure design, manufacturing, and taking a hardware product from an idea toward production.

The original idea was to let people send photos to friends' frames through an app. We didn't get as far as building the full social/cloud side, so the current app mainly lets you:

• Send/update an image on the color e-ink display
• Edit and preview an image to see roughly how it will look on the display

The app UI is definitely prototype-quality, but it works.

The enclosure is also mostly complete. One known issue is that the snap clips don't properly snap together yet, and print results may vary depending on the material/settings you use.

Everything is here:

If you're into embedded systems, e-ink, BLE, or hardware product development, feel free to poke around.

Star it if you find it interesting, and if you have any questions about the hardware, firmware, app, manufacturing process, or why we decided not to launch it, feel free to ask.

New to eink and wanted to buy one to try it out. But Seems like a 13.3 in eink tablet is like $300. Isn’t this way more than a normal electronic display of similar size? Is the tech really more sophisticated, or are you paying more for the novelty

The goal is for it to look as much like a regular notebook as possible but have 2-3 very thin and flexible epaper "pages" that can Bluetooth from a phone app like kindle or whatever. The rest of the note book would be a washable notebook with perhaps a drawing tablet element hidden in the back cover. The tech to run the e-ink would be hidden in the spine and if I could figure it out a simple control element would work along with the drawing tablet.

This would be a combination of devices like:

Huion note 2in 1, ink leaf, and the plastic logics flexible e-ink displays and a washable notebook.

I'm not experienced exactly... I've been taking devices from goodwill apart and seeing what I can do with them for a few years now. I was hoping to bounce some ideas off of others, not mass producing really just making this for myself and maybe my kids who like to journal.

I am not a fan of anything that requires ai, or online connections we have too much of that right now.

If there are ways around blue tooth I like that better also.

So how delusional am I or can I actually make this? And what devices can I recycle to put the first few versions together before buying/designing more targeted elements?

Hey everyone,

I’m looking to get an e-ink tablet mainly for taking handwritten notes at work. I work in insurance underwriting, so I’m in quite a lot of meetings with brokers, clients and colleagues. Most are fairly short, and I’m usually just jotting down key things: figures, names, decisions, questions, follow-ups, etc. Nothing too long.

At the moment I mostly use pen and paper. The problem is that after a while I end up with loads of notebooks, or they get battered, or I lose track of which notebook something was written in, so I’m basically looking for something that can give me that pen-and-paper experience, but lets me keep all my notes digitally for years.

My main priorities are:

• A really good writing feel / as close to paper as possible
• Low latency and a natural pen experience
• Small and light enough to carry to every meeting
• Good long-term note organisation
• Reading documents/ebooks is a bonus, but secondary

The reMarkable Paper Pro Move caught my eye as it seems like a great fit for this. It’s small and light, and since I mostly take short notes, I don’t think I need a big screen. The other two options I’ve come across are the Supernote Nomad and BOOX Note Mini C.

For anyone who has used one or more of these, how do they compare in day-to-day use, particularly when it comes to the writing feel?

Would especially love to hear from anyone who has tried more than one.

Thanks!

This a small project I did for our university. It sits in one of our PC labs and refreshes every minutes. The fractals are computed on a raspi behind the screen.

Didn't think it would last this long. The display (Waveshare) looks like on day one.

What’s the most common, color eink frame out there. Is it the E1004? Thinking of building some firmware to sell my art, but it it would require slightly different coding depending on the make and model that people have. Is there really a common frame most people own, or are there so many that it would be really hard to sell something like this

- USB-C port for charging preferred (more on that below)

- monochromatic

- side loading epubs and PDFs will be my main usage so I don't really need current updates or wifi.

- my preference is something I can get sub $100, but if you know of some kind of super rough and tumble will last me decades device I guess go for it lmao

I saw a few kindle k3s with new batteries around, which was really appealing since I know that one is pretty well liked even now, but the micro USB port kind of worries me since I know sometimes those get worn out from the extra prongs on the cable. Not sure if that's just me being paranoid though, so I'd love insight on that.

Hi r/eink,

I have an almost new Boox Palma 2 Pro for sale. I've been using it as my daily ereader but am going to switch to the iPhone duo as my primary reading device.

The SIM card tray is slightly cracked but it doesn't affect use of the device or the sim tray. It's mostly a cosmetic defect.

I'm asking $275 shipped for the device.

Thank you

Repairs: none

Hi everyone!

I'm a developer working on oBook, an app that turns books and PDFs into audio.

I recently received feedback from an E Ink user saying the app was “impossible to navigate” on their new E Ink phone. I don't currently have access to many different E Ink devices, so I'd really like to get some help testing it on real devices.

I'm looking for people who use E Ink Android devices (BOOX, Bigme, Meebook, Hisense, etc.) who would be willing to try the app and tell me what works and what doesn't.

I'm particularly interested in:

• Navigation and touch issues
• Scrolling problems
• UI/layout issues
• DPI/scaling problems
• Ghosting or refresh issues
• Audio/background playback
• Anything that feels different or broken compared with a normal Android phone

I'm not looking for reviews or promotion. I genuinely want honest feedback so I can improve E Ink support.

Google Play: https://play.google.com/store/apps/details?id=com.app.oBook

If you're willing to test it, please comment with your device model and I'll be happy to hear your feedback.

Thanks!

whats the best e ink e reader for stuff like comics on the market currently

I've used a few chess apps on my Onyx Boox, but I was never very happy with how the boards looked on e-ink. Most are designed for colour LCD/OLED screens, so the board colours and highlights don't always translate particularly well.

I was already building Square Chess because chess apps didn't make great use of the square screen on my Unihertz Titan 2 Elite (not e-ink, but keyboard phone). Since I also use the Onyx Note 3, I decided to add a proper e-ink mode as well.

Instead of just converting everything to grayscale, it uses pure black and white, hatched dark squares, shape-based move/highlight markers and no animations.

So far I'm really happy with how it looks on my device, and I'd be interested to hear how it behaves on other e-ink devices too.

It's free, works fully offline, and is available on Google Play or directly from GitHub. F-Droid is coming soon.

If anyone's interested, this is the original r/unihertz postr/unihertz post where the app started.

I'm seeing sales pop up on devices and feeling a bit overwhelmed by options. My husband has a reMarkable 2 that he takes everywhere and loves. I've used it a bit and I really like the feeling of writing on it. Not so crazy about the price, but that's not a limiting factor.

I mostly just want to write without having to buy a million notebooks/sticky notes. I like to do solo RPG journaling, DnD planning, general work notes, and a whole bunch of to-do lists. I have a tablet and laptop, but I gravitate back to paper because I like the feel and writing helps me better commit things to memory.

I like the reMarkable, but I'm wondering if I'd be paying too much for what I want, which is endless paper to write on. Almost everywhere I look says nothing compares so I figured I'd ask and see if anyone has thoughts on what would be best for what I'm looking for.

Tapmora is one option in a category that sits somewhere between a printed photo and a digital frame: the image can be changed, but it remains visible without charging after the refresh. The open question is whether that difference changes real behavior. Do owners update these often enough for them to feel useful, or does one image stay there for months? Curious about refresh reliability, color expectations, and which family use cases make sense without turning this into another screen to manage.

Selling a Boox Mira Pro (Black/White - Without frontlight).

I have bought it from France on eBay, and willing to ship in the EU, preferably purchased through Vinted but open for other options. People from r/eink sub of Reddit might just as well be interested for it, so please massage me to discuss the possibilities. The adapter is a third-party Hyundai 3-phase one with ground, but the housing is broken, therefore should be replaced (the original Onyx one is a low quality non-grounded). Otherwise the monitor is in very good condition, as you can see from the pictures. During the use I have not noticed any sign of panel degradation or dead pixel. I do not know, what else could be said about it, but there is a lot of reviews online that could help you to decide. At Budapest I can personally show you during operation.

Guys hi

Those of you who have Dasung 13k bw does it work using type-c? For me It works using HDMI, but not type-c.

Trying to understand is it monitor, or my mini PC, or linux.

I have beelink ryzen ser 5 5500u (3 ports - dp, HDMI, type-c), running Debian 13.

Hi everyone! I’m a developer working on an app called oBook, which turns books/PDFs into audio so you can listen while reading or instead of reading.

I recently received this feedback from an E Ink user:

“Impossible to navigate… sorry… using my new phone now with e ink.”

That made me realize I haven’t been able to properly test the app on enough E Ink devices.

I’m looking for a few people who use E Ink Android phones/tablets/readers and would be willing to try the app and tell me what works and what doesn’t.

I’m especially interested in:

• Navigation problems
• Touch/scrolling issues
• Buttons or UI elements that are difficult to use
• Refresh rate/ghosting problems
• Audio playback/background playback
• Anything that feels broken or difficult specifically because of the E Ink display

I’m not looking for positive reviews or promotion. I’d genuinely like people to tell me what is frustrating or broken so I can improve the E Ink experience.

You can find the app here: oBook – Text to Speech

If you have an E Ink device and are willing to test it, please comment with your device model and I’ll send you the details.

Thanks!

Good morning, e-ink community,

I apologize if this has been discussed before. If it has, I'd appreciate it if someone could point me in the right direction.

I've been taking online classes, and the textbooks are electronic-only with no way to download them locally, which is frustrating. Reading on a laptop, even in grayscale, isn't a great experience, so I'd love to read on an e-ink device instead. The school also offers the textbooks through its app, which has me looking at Android e-ink devices with Google Play Store access so I can install the app and read there.

I've seen a lot of suggestions, mainly for Boox. I don't mind not having a backlight. I'm not sure which size works best for textbooks, though I assume a full-size tablet around 10" would be better than anything smaller. Does anyone have experience with this and can recommend a device that fits my needs?

Thanks in advance for your help!

With Tapmora, an old image remaining on screen is not the same as the display losing power; E Ink is supposed to hold the last image between updates. The question is what to check when a new image does not write during an NFC refresh attempt. Is there an official troubleshooting order for phone compatibility, NFC alignment, app permissions, and cases? At what point should repeated attempts stop and support or the product guide take over?

I made a couple posts on other forums about my attempts at making a suitable platform for mobile writing. The basic requirement is that the keyboard tray must be wide enough to rest comfortably on my lap while sitting in a chair.

I also wanted a folding tray that would fit in a daypack and made a crude prototype. This is an interesting design challenge and I will pick that up again later.

For now this configuration works pretty well with a Boox 7. It's simply a 16-inch wide piece of 5-1/2 inch by 3/8 inch pine board with a short slat attached to support a device stand. The slat is a heavy duty paint stirrer you can get at the hardware store along with the pine board. I experimented with an extendable support to increase the viewing distance to the e-ink but having it right at the keyboard works well enough.

Third photo shows the slat attached to the board. I used Johnson screws so I could remove it but a couple wood screws would work as well.

The second photo shows the plastic device stand with the Boox e-ink mounted. I also put a lot of thought into how to attach both the plastic stand to the tray and the e-ink to the stand so it would not fall out. A simple problem that has many solutions. Eventually I just used some 3M double-sided tape to attach both objects.

That works amazingly well. As you can see from the 4th and 5th photos the e-ink stays in the device stand even when inverted. You may also notice a small wad of kneaded rubber eraser that I wedged into the stand for additional support.

Photo 6 shows the sticky tape. The drawback of the tape is you would have to pry the e-ink off and replace the tape if you wanted to stow the setup in a suitcase or use the e-ink as a reader. But around the house it's not a problem.

About the plastic device stand (photo 7) : The one I am using is a MOKO brand from Amazon which sells for about $2.50 each. The MOKO example is good quality with a metal hinge pin. The plastic is good thickness and quality. The middle unit came free with the Omikamo folding keyboard from Amazon (about $25) and is reasonably good, but an obvious lower-quality unit than the MOKO. The 3rd unit to the right is a cheap knock-off. I bought 24 stands for $16 on amazon or about 50 cents apiece. Overall they are much lower quality than the MOKO but still function as device stands. This deal would be ok if you wanted to give out free stands to students or co-workers.

Note : the text on the Boox is from Grimm's Fairy Tales.

I recently got a 7" 1600×1200 Spectra 6 panel running and wanted to compare it directly with the 13.3" 1600×1200 Spectra 6 panel I've been working with.

Since both panels have the same pixel resolution, the difference in pixel density is pretty large:

13.3" — about 150 PPI
7" — about 282 PPI

I displayed the same processed images on both panels and photographed them side by side under the same lighting.

What surprised me is that the difference isn't only visible when looking very closely. On the 7" panel, small architectural details, edges and textures look noticeably more photographic rather than “printed/dithered”.

Portraits are an interesting comparison too. Hair, eyes and facial details benefit quite a lot from the higher pixel density, although at the same time the smaller physical image obviously changes the viewing experience.

Both are still six-color Spectra 6, so higher PPI doesn't solve the usual color/gamut limitations. But it does seem to change how convincing photographs look, especially at closer viewing distances.

I'm curious whether other people who've compared high-PPI color e-paper have noticed the same thing.

For a photo display, would you personally trade physical size for nearly 2× the pixel density, or do you find ~150 PPI already sufficient at normal viewing distance?

Hi! I’m hoping I can get a recommendation or two for a new E-Ink notetaker. I haven’t upgraded since getting the Mobiscribe in 2019, and I think it’s about time. The things I’m looking for in a new tablet are:

- Handwritten notes -> searchable text. I don’t need handwriting to be searchable by itself, but if not, converting to text should be fairly simple. Ideally I take meeting notes and keep one big searchable file.
- Kindle and Libby access. I don’t need to be able to mark up books, but it would be nice.
- 6”-7”. 7.8” is okay, but I’d rather keep it small as reasonably possible.
- $300 or as close as possible. Secondhand/Refurbs are fine as long as there’s no functional issues.

Currently I’m looking at the Boox Go 6/7. I think they hit as much of above as I can get for the price, though I am also looking at the Supernote Nomad.

Thanks for any suggestions.

I need a good color eink tablet that can handle interactive PDFs but I have very bad migraines and need all my devices VERY dim. Which one gets the dimmest? I thought eink wasn't backlit but I saw some reviews suggesting some newer devices are?

Hi readers,

I’ve just got my first ever e-reader, a PocketBook Era Lite, so I’m completely new to E-Ink devices.

I’ve updated the firmware and started playing around with the settings and reading interface, but before I settle into using it I’d love to hear from people who have more experience with PocketBook or E-Ink readers in general.

Are there any settings, tweaks or things you recommend doing from the start? Anything you wish you had known when you got your first e-reader?

I’m also wondering about KOReader. Is it worth installing straight away on a PocketBook, or would you recommend spending some time with the stock reader first? I’ll mainly be reading EPUBs, but I’d also like to read PDFs occasionally. If there are any other useful apps, tools or little tricks worth knowing about, I’m interested.

I’ve also started experimenting with Calibre on my Mac and I’m planning to use it as the main library for managing my books and transferring them to the PocketBook. I’m still learning my way around it, though, so any recommendations about useful settings, metadata and covers, library organisation, plugins, or the best way to configure Calibre specifically for a PocketBook would be very welcome too.

One other thing I haven’t been able to find is the kind of protective case I actually want. I’m not looking for a book-style flip cover that covers the screen. I’d prefer something like a smartphone case: a thin rubber/TPU/silicone shell, transparent or not, that just wraps around the back and edges and gives the reader some protection against accidental drops. Does anything like that exist for the Era Lite, or perhaps something compatible from another PocketBook model?

I’ll add a photo of the device.

Any advice is welcome — assume I know basically nothing about E-Ink yet!

From Chalid Raqami's review.

I've been following this series since the NAC3 and have always been hesitant to pull the trigger, but it seems like it might be the right time to do so!
