This looks a lot like it's just a waveshare e-ink display in a case with a esp32. Is there something more there? If that's the case, ALL the work here is going to be software, and I don't see any yet. IIRC, that calendar display is example code from somewhere (the weather icons, in particular).

Yup pretty much. But everything is open source. checkout their github page https://github.com/rgujju/paperdink

Thanks. The code is the example code for our product. but it does not have any other example code. It uses open source libraries and icons.

Unfortunately all of this is hampered immensely by the still way too high price of E-Ink displays.

What are you going to build with this, a price tag? I'd love to make some stuff using E-Ink displays that you can read from a few meters away, but screens at 8 or more inches are virtually unobtainable. :(

You're right, price is a big issue. We want to be able to provide affordable and useful e-paper displays and are actively working towards the vision.

Here's some hopefully constructive feedback. The RGB LED looks jarring against monochrome e-ink screen. It also gives impression of cheap electronics, and rough 3d printed case doesn't help. The e-ink feels elegant, solid (no flickering) and timeless, while LED is nervous, overly bright and loud. If you really need a LED, put a white one. Maybe try to prototype audiophile hi-fi style case. Something wooden or even bl…

That was surely insightful. We'll test with a white LED. And we're working on the binaries and GUI, it seems like current hardware won't be able to serve web pages.

Why do you need an LED at all?

im in the market for a 20~40 dol e ink, delivered in EU, programmable screen that could last unmaintened for 6-12 months at a 1/day refresh rate. Should be in the 12x12 cm surface and needs to showcase a ~15 characters simple QR code.

nice to have : JavaScript programmable

Any experience with that ?
