I got the X4 and liked it enough that I used it a ton even though it turned out to be too big to Magsafe onto my phone. In fact, I liked it enough that I also got the X3 on sale so I can use it the way I originally intended to use the X4.

I got the X4 a few weeks back and installed https://github.com/uxjulia/CrossInk and it has been a dream.

Love my X4. Shameless plug, I also built an iOS/Android app to manage books and also send web articles over to Crosspoint

Thank you. I'm not the biggest fan of the Crosspoint web interface, so I'll definitely give this a try.

Hijacking … i have some random e-ink displays (from a bought product)… there seem to be 6 lines to the mcu (or 7, havent measured). Any 2026 tips on approaches to reverse engineer this to run on an arbitrary hobby mcu like esp32? Oh the mcu seems to be a WinnerMicro W100 Series MCU (arm m3)

I’ve been looking at these for a while, hoping the custom firmwares for it will become more popular, as I was considering getting this for my six-year-old.

The disabled usb is certainly a bummer. I wonder how they disabled it though – is there a hardware difference?

Crosspoint is very popular and very easy to flash onto the device.

Locking and preventing flashing of firmware only happened in China.

This page mentions international models, but seems it's still possible to flash them in any case

As someone who has resisted buying an e-reader for years because I "prefer physical books", I finally purchased a Kobo Clara BW and love it. Even though I usually only read one book at a time, having my whole library in a small form factor is really wonderful.

The no USB flashing doesn't appear to be the case if you get it straight from OEM. It is a bit pricier than amazon.

I love this thing and I use it a lot more than my kindle and my kobo (with koreader). I really like the form factor and the fact that goes out of sleep almost instantly and goes to sleep equally as fast. It seeps battery. It is perfect the way it is.

Have the X4, the size is perfect - I always have it in my pocket and can read a view pages whenever I am waiting for something. Reduced my phone usage / doom scrolling nonsense with it. Best 50€ spent in a long time.

I skimmed over the project a bit. It seems quite ambitious to aim to reimplement epub, considering that means supporting HTML, CSS, SVG and JavaScript.

Is there a ebook format that isn't just build arround the concept of a webbrowser?

While I agree in terms of modern browser expectations (and books absolutely should not need JavaScript), I think books in HTML makes a lot of sense. HTML was meant for sharing text documents, after all.

epub is overkill for a vast majority of books.

A format that only supported

- headings

- paragraphs

- emphasis (bold/italics)

- bullets

- inline images

is good enough. A simple container with a TOC pointing to text blocks/files within it that can be processed very cheaply.

Unfortunately, with something like epub, you lose all the simplicity because you want to support every single feature even if rarely used.

HTML and CSS is enough for 99% percent of epubs, and that's the only subset of epub standards that Crosspoint tries to support

Isn't HTML and CSS already a huge surface to support, unless you are happy with a subset?
