Diptyx Open Source Dual-Screen E-Reader Launches on Crowd Supply (linuxiac.com)

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.

If this were a single screen device, I would've given it some serious thought. I'm reading one page at a time, so I don't see the point of a dual screen e-reader. Single screen would be cheaper, and also lighter.

I guess I'll stick with my Kobo for now.
