Rust (and Slint) on a Jailbroken Kindle (sverre.me)

the code: https://github.com/sverrejb/slint-kindle-backend

This looks cool, and one of the first posts I've seen on HN in a few months where I genuinely wanted to try it.

Good work! I guess you need to leave it plugged in?

This is cool, thanks for sharing. I recently compiled Rust / Slint on a LicheeRV Nano, which is RISC-V 64bit musl[1]. It's a little portable audio player I'm working on, the compile process is done via custom Cross docker image.

Currently I'm evaluating Battery Pal[2], because the TP4057 Module was not stable enough to power USB-C to 3.5mm Adapters reliably. So far it seems to work as expected.

This is awesome! How reliable are kindle jailbreaks/avoiding updates, etc?

Have opted for other devices like the xteink (or a boox in the future) due to what seemed like a relatively small ecosystem around “aftermarket” kindle modifications.

The kindle would be a great option if it could be reliably jailbroken and loaded with custom software

Great article. Hacking old kindles is fun! I encourage everyone to give it a try. The retro feel of eink makes it special for me.

I wrote about my experience in cross compiling zig on an old kindle some time ago.

Tangential, how does slint fare compared to Druid/egui(?)

zig as a cross-compile backend for rust is so good.

I am working on a self-hosted library server for jailbroken kindle and opted for using pure Rust for the KUAL app to sync books and annotations with the server.

It's just running `cargo build --release --target armv7-unknown-linux-musleabihf` with a .cargo/config.toml:

``` [target.armv7-unknown-linux-musleabihf] linker = "rust-lld" rustflags = ["-C", "link-self-contained=yes"]. ```

the downside is I can't use any c-deps. :)

Is there a list somewhere of jailbreak-able kindles? I've been thinking of getting one to toy with for a while, but I don't want to accidentally get one that is more heavily locked down, or that we cant run our own code on for some reason

Would be so nice to use those previous Paperwhites for something like this as well. Instead I just lose them while travelling. Just lost my last 2019/smth edition. 3rd one with such fate..

Funny I have a paperwhite too I hate that forced ad thing (on screen wake) which apparently you can pay to get rid of

I jailbroke my kindle a while back and was super excited to do it, but then didn't really do anything past that. Besides de-amazoning it, I found no real value nor supplemental features that were actually worth while. That being said, I don't regret doing it, just kind of wish there was more.
