Diptyx is a new open-source e-reader now crowdfunding on Crowd Supply, positioning itself as a long-term alternative to locked-down commercial devices. Built around an ESP32 microcontroller and a distinctive dual-screen design, the device focuses on ownership, repairability, and offline reading without DRM or cloud dependencies.
The most striking aspect of Diptyx is its book-like form factor. Two 5.83-inch black-and-white e-ink displays are joined by a hinge, allowing the device to close like a physical book and protect the screens without requiring a case.

Not a fan of the dual screen, but I am a big fam of open source ereaders. Options are currently limited. If any one of the FOSS book projects takes off, we’d all benefit a lot!
Why would I need two displays?
to feel more like an actual book probably
That’s like the worst part of an actual book to me. I’m only reading one page at a time. The second page is just kinda in the way until I get to it.
Yes, that’s the official idea.
I myself would love a one-screen-half-price one tho.
But I am happy such projects exist, it’s the foss sphere that should be going mainstream & shape our culture, not monopolistic megacorps.
The open book is sorta what your looking for.
Yes, there are a few, but I meant like this one but with one screen.
I’d really love this if it can have two different books open at once, one on either screen.
I wish it had magnetic sides with connector, and could work as one OR two devices.
