Battery life is good... And we saw it go from 98% to 96% in a 1 minute video.

I’m working on custom firmware with an extensions system for the XTeInk X3/X4. It’s still in a very early stage, but I’m grinding hard on this one: https://github.com/marginalia-os/marginalia-firmware

Biscuit is definitely one of the more entertaining firmwares for certain.

I actually bought that and loaded Harry Potter into it haha. Where do you get the biscuit firmware and how are you flashing it??
@fiddygobragh2026-06-08
Can it still also be used to read e- books with biscuit loaded?

Is biscuit gone?
@tamcgath2026-05-27
Can I make it into a little writing pad or is the refresh rate too low?

If it’s a full display how does it not need to full refresh when it scrolls over sections?
