I am building something like this, but the pandemic has prevented me from collaborating with my frame maker. The e-ink panel I have has a fairly fragile ribbon cable we are trying to hide inside the frame with some clever cuts. I am not sure how the panels for Kindles allow them to have such small margins. The biggest problem I have is fitting a battery into the frame -- I was trying to find a low profile USB battery…

#43The picture frame runs for years, unlike their web site. "502 Bad Gateway"
Appearing on HH's front page can put quite a load on an usually low-traffic website and put it on its knees quickly.

#44I worked on a number of digital photo frames, including on ones like that. E-ink is not the most suitable thing for it in its current form. First, large size EPD cost an arm, and a leg, and custom one costs even more. Second, there are no 8 bit EPD controllers as of now a mortal can buy, which means grays look very bad. Third, there are inherent physical limitations which make increasing gray resolution of EPDs quite…

What would you suggest for an affordable picture frame displaying digital art?
A second hand TV? Large size LCDs got ridiculously cheap with time. It may be cheaper to by a 40 inch LCD panel, than a 10 inch high-end Eink

If you can plug it into a wall, have a Raspberry Pi 4 series driving a 4K TV of the size of your choice. The cheapest one I see on Amazon right now is a 40" 4K HDR from Vizio, with quite a small bezel - $240. Hang it on a wall and paint the bezel white, or make a nice wood frame for it.

40" is massive for a picture frame
You can give them special frames and mattes.
You can show 36 Views of Mount Fuji all at once, and then two at a time.
And you can watch Netflix on it later.

#49This is an advertisement linking to a broken storefront in case anyone was wondering. Maybe the creator can share more about the design of this device (ex/ what embedded device you're using (ESP32?), is an ASIC driving the display, epaper supplier, etc.)? Have you considered using E INKs Kaleido coloured epaper?
not everybody cares about the selling part more than the building part...
