Turning an old Amazon Kindle into a eInk development platform (2021)

1 month ago (blog.lidskialf.net)

I've tried these in the past but always found the software/firmware side of it too fiddly for the reward (against the grain for a lot of people, I know), which is a pity as the hardware side is really rewarding (for me).

Recently, doing it with Claude Code was a breeze. If you are more interested in the outcome than the process, then I'd say it's a great time to buy a few old Kindles and see what you can create with them.

I've never really had the patience to fiddle a lot of with the hardware but have always wanted to use e-ink screens for working, specially on the move. (Tried the hacks for remarkable pro with a friend's recommendations, ultimately never kept using it).

The boox palma with android + (obsidian | termux + tailscale) when I need it has actually worked out well for me for writing | programming with a portable keyboard (nuphy). I even did this year's Advent of Code on it. (https://knlb.dev/logs/aoc25 has some photos)

The kindle system is a joy to dig around in. The UI‘s based on X, awesome WM, GTK and a bunch of mostly unobfuscated shell scripts and JS.

One thing I‘d love would to find a way to make it wake up every once in a while to turn it into an auto-refreshing display. I haven’t found a way to do so without external hardware (which could save a lot of power by not having to wake the whole system, but I think the wakeup can’t be triggered via the serial port and other contacts aren’t as easily accessible).

I broke my old kindle when trying to open it. His nice description on how to get inside would have been a big help…

While cool, ultimately not usable due to the very limited hardware.

  • Limited hardware is exactly why it is usable. Many e-ink devices exist now so limiting factors such as refresh rates etc, need to be considered when developing apps for android etc nowadays.

    • They might be maining that it requires a specific ereader model rather than being generic, but I'm not sure that really applies either. Kindles, even any specific single model of kindle, are generally readily available.
