I flashed my Kobo and have a pretty similar experience now. Except with a decent size screen.

I've had a Kobo Clara BW for about 2 years. I use it almost every day and I love it. I think it was about $140 when I bought it. They go for $160 now, but I think the bigger screen makes it a better buy than this e-reader. I love crowd-funded projects, but Kobo is a better option, imho.

Why did I read that as 150 buttholes?

If they are targeting the tiny ebook reader niche, they're going to have to do better on features and pricing than the upcoming refresh of the XTEINK devices.

[–] foggenbooty@lemmy.world 7 points 1 day ago (3 children)

But XTEINK is actively working to combat the flashing of open source software. It seems they had a spike in sales and interest due to their affordable hardware, but if they continue to lock aftermaket software out tech savvy people will be looking for different options.

I'm looking for an open source ReMarkable alternative. A4 sized preferably. Any options out there?

Okay, but... Isn't pocketbook good enough?

[–] Anivia@feddit.org 5 points 1 day ago

Pocketbook is great, and runs Linux out of the box. But it's not available globally

Damn, at 10mm thickness that's a chubby little SOB, nearly twice as fat as my leaf 2. And with a tiny 4.26" screen on top of that, yikes...I love my 7" screen, I'd hate to read on a screen smaller than that.

But can you get books to read on it? I suspect that these gadgets will get locked out of the market by the thugs.

[–] partofthevoice@lemmy.zip 3 points 1 day ago

These gadgets were locked into the market, locked out of everything else. Usually, how these things go, the community version supplies interfaces for downloading content from third parties.

Lock the gadgets out all they want. That’ll only make more interest around having all the popular new books available on platforms that thugs can’t control.

If anyone wants to see the old project: https://hackaday.io/project/192688-the-open-book

Its been around for a bit. The newest iteration looks like its trying to be more like kindle.

GH page: https://github.com/joeycastillo/The-Open-Book

I forget where but the developer goes over the cost of the physical hardware a couple of years ago somewhere. Its kinda expensive to make your own open source ebook reader from mostly scratch.

I like this version: https://www.oddlyspecificobjects.com/projects/openbook/

[–] mesamunefire@piefed.social 5 points 1 day ago* (last edited 1 day ago) (2 children)

Very similar to https://diptyx.dev/

But its been around longer. Software looks really good for an esp32. Im hoping we see more of these open source ebook readers pop up.

It's DRM-free by design. Any book you want to use in it will need to have it stripped off.
