Wow, this is great! I've been hoping for eInk with good refresh for years, and seeing it in action in your demo is very cool. > The screen can refresh up to 30 times per second, this will degrade the eInk display rapidly. Do not use with fast changing content like videos. Have you noticed the degraded display in your Kobo? I imagine it's not uniform across all pixels, since editing would mostly be localized to your c…

Thank you :)

I haven't noticed any degradation, but I put the warning up just in case. There is research suggesting that the ink "drops" stick together or break up after so many refreshes.

I'd love to see someone crack the partial fast update modes of the Boox tablets.

They run Android apps, but only the included, closed-source apps like the note-taking app and browser get fast screen updates at high quality. If you try to install a third-party note-taking app the experience is crap.

Exactly what I've been wanting to do, use it as a display for emacs with a bluetooth keyboard. Don't mind if it has to pass through my laptop. Does anyone know how to do something similar with the reMarkable 2?

There's https://github.com/matteodelabre/vnsee if you want to use VNC as a client on your remarkable. I've used it in the past to run Chromium on a server and display it on the reMarkable: https://photos.app.goo.gl/TnNE1tdzvrwphJ8N6
