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.

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

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?
