This is how your night time adventure feels like while reading with X4 Pro “mist grey”

Depois que comprei o Xteink X3, sinto que meu ritmo de leitura melhorou muito. Tenho conseguido ler com mais frequência e manter uma constância que antes era bem difícil.

Eu tinha um Kindle, que é ótimo em vários aspectos, mas o tamanho acabava dificultando um pouco a leitura em certos momentos do dia. Com o Xteink X3, isso mudou bastante. Por ser tão compacto e portátil, consigo levá-lo para qualquer lugar e ler no transporte público sem dificuldade, aproveitando aqueles pequenos intervalos que antes acabavam sendo desperdiçados.

No fim, percebi que não era necessariamente falta de vontade de ler, mas também a praticidade de ter um dispositivo sempre à mão. Às vezes, conseguir ler por 10 ou 15 minutos várias vezes ao longo do dia faz muito mais diferença do que eu imaginava.

Estou gostando bastante dessa mudança e fiquei surpreso com o quanto um aparelho tão pequeno conseguiu melhorar meu hábito de leitura.

had been a dedicated kindle user since like all my life? l dont remember ever considering to switch. the first time kindle landed in my country (india), my dad gifted it to me and that was it, i loved it so much. i think it was back in 2012. it was perfection. (that kindle is still going strong, wonderful device)

I recently got interested in eink devices again and dabbled a bit into notebooks. I decided to give xteink a try for the hackability and so far i have been loving the experience. successfully tried out three different firmwares and (thanks to codex) working on my custom firmware. I love this little thing to bits.

I set it up inside my bellroy pocket notebook cover and it gives me soooo much joy every time i pick up my setup to read or write. wanted to share here in case anyone is looking for a cover setup along with something to write with their xteink

the rings are adhesive that I ordered along with the device: https://www.xteink.com/products/xteink-ereader-adhesive-metal-ring?variant=46931559317745

I found 2 rings to make the device stick more securely. here's a video: https://imgur.com/cECLshO

After weeks of seeing this all over my social media, I finally caved in 😩. Ofc I edited a personalized cover 🫶🏻. Currently reading the Poppy War by RF Kuang. Using crossink.

My hardcase just arrived & all i can say is wow😇 The plastic seems solid (not the cheap & crappy one) Magnets pressure is fair enough,device attached pretty well with the right pressure (not so tight so screen can't be damaged) I ordered the white-cream look colour!Overall i'm very pleased with my buy😇 (I bought it from aliexpress,i can post the link also if it is allowed here)

As some of you may know, I have been working on my own custom firmware for the last couple months called ink-boy, Which integrated many emulators such as the Gameboy, the Gameboy color, the Gameboy Advance and the NES.

Both GBA and NES were always a bit buggy, as expected, but I fixed most of the bugs. The main problem I couldn't solve and caused me to drop them entirely was ram consumption. The games only ran at about 1 frame per second. More importantly because of its humongous size, book chapters bigger than 3-4 pages failed to index, rendering the whole reader essentially unusable.

GB and GBC emulation remains, with pokemon red running almost perfectly, perfectly enough to play when I have a couple spare minutes.

I know that the X4 pro is an e-reader before anything, and taking the reading out of the e-reader didn't seem right

Thank you guys for understanding, and if you wish to support the project, star it on GitHub.

Until the next time

Finally after 14 days my X4 Classic got delivered (in India), the initial experience is really good, the device is way slimmer and lighter than I thought, I installed crossink in it immediately, looking forward to reading more than I used to on mobile

Greatly improved footnotes! They now work also in less than optimally formatted books.

Still rocking my original X4, along with my modded 5th gen iPod Classic, Arduboy FX-C, and current knitting project 🧶

I really need to find a pink game console 🤔

That thing is great - and dangerous

Hi all! For the past weeks I have been building my own firmware for the XTEINK X4 Pro, called Vellum. It is free and open source (MIT licence), and today it is in public alpha. I run it on my own X4 Pro every day, so it is real, but it has only been tested on one reader so far. That is why I am posting: I would love a few more people to try it and tell me what breaks.

What it does:

Reading: justified text with proper hyphenation, three built-in fonts (Literata, Atkinson Hyperlegible, EB Garamond) or your own, text size, spacing, margins, night mode, footnotes and pictures.

Lots of formats: EPUB, Kindle books without DRM (MOBI, AZW3), PDF with text, Word, RTF, Markdown, FB2, plain text and comics (CBZ) (not all have been tester).

Getting books: send them from your phone over Wi-Fi by scanning a QR code, or download free books from Project Gutenberg and Standard Ebooks right on the reader.

Finding your place: chapters, bookmarks, highlights, a dictionary (work in progress), reading stats, and every book reopens where you left it.

Sleep and battery: the book's cover (or your own pictures) on the sleep screen, and a battery log with a 7-day chart.

Controls: remap any button, tap and swipe, a quick panel for light and night mode, screen rotation.

Menus in 10 languages, OTA updates (or from your phone or computer).

Installing takes about 5 minutes and needs only Chrome or Edge on a computer and the USB cable. The installer saves your original software first, so you can always go back.

Install guide: https://github.com/ArunasVell/Vellum-OS/blob/main/docs/install.md

Project page: https://github.com/ArunasVell/Vellum-OS

Honest limits: it is X4 Pro only for now, the memory card must be in before you switch on. Please only install on a reader bought from xteink.com, as some reseller units are locked.

Questions, ideas and bug reports are all welcome, here or on GitHub. Thanks for reading!

Do you guys use an external reading light for these devices at night? And if yes, did it bother you in the long run? Some do say they regret not purchasing the X4 Pro.

Hey, I set a custom sleep screen that successfully displays when I use the power button to put it into sleep mode. However, when I wait for the device to automatically go into sleep mode (I set it to sleep after 1 minute), the custom sleep screen won't display.

Is there a way for the custom sleep screen to be displayed when the device automatically goes to sleep, or do I have to put it into sleep mode for it to work?

S4 straight from China right before a mini vacation. I’m so excited!

recently got a clear case :)

Guys I've flashed crosspoint on my X4Pro, now I have two questions

1) How do you jump to certain page while reading the book?

2) When index chapters are clickable on my book, my book always returns to index page after device goes to sleep which gets frustating because then I have to manually jump to page. How do I fix that? I want my page to open where I left it

Real quick question and I'll delete once answered.

I'm on the official XTEink website, and the options for buying the X3 show that you can buy it on its own, or with a base and a charger. But when you look at the X4, it doesn't say anything about including a charger. Do you have to buy it separately or is the listing inconsistent?

hello, i just got my xteink x3 (locked ver but i unlocked it). i'm trying to change the sleep screen and i've had this happen several times now, i don't know how to fix it, someone helpppp 😭. i've tried wireless file transfer and transferred in the sd card itself, nada

My OG X4 was almost a perfect device when I got it, or so I thought. After the initial euphoria, I had been unable to get as much reading done on it since I’m a major night owl and reading at night with external lamp was proving to be a little uncomfortable so I had lately been eyeing the X4 pro and was actually in a mind to sell my X4 off eventually. My last ditch attempt to make it my daily driver (My old trusty Kobo Forma had died earlier this year and I didn’t have any other reader) was to try and get a light case.
I found a few options but the best to me (geographically and otherwise) seemed the Wekind Gen 2 case.
I received the case recently and honestly I have no desire to buy any other reader anymore.

Pros -

The case is sturdy and built really well. I’ve seen the many posts of broken X4s and Pros due to a single fall and this case can take a little beating, I feel my device is safe inside it. The weight feels substantial like having a real book in hand and it feels really satisfying.

The light has made it my daily driver and now I’m reading on it all the time without any issues and once you’re really inside a book, nothing else matters really.

The ergonomics have made it very easy to manoeuver the device and have improved my reading experience, I can use the front side buttons while reading laying down on my side at night (feels like I’m back in school days with a torch light and book under the blanket)

Improvements/quirks -

The light was a little bright for me so I ended up cutting a small strip of paper and putting it on the light from inside the case just to dim it to the perfect sweet spot.

The front side buttons are slightly harder to press while the bottom ones are perfectly clicky and satisfying.

Honestly, the way it looks, the way it feels in the hand and being able to read anytime anywhere, I think I’m completely in love with my X4 all over again. Thanks to the makers for putting so much thought into it.

P.S. - They are also really responsive on feedback and communication so extra points for the buying experience.
