For people complaining about price, large eink panels are insanely expensive. The cheapest 13.3" panel with a min order of 1 is around $400-450. That's for a panel with no driver board. If you're interested in an easy diy approach, you can pick up a 10" panel with an arduino hat here for $200 [0]. Although if you step down to normal ereader sizes, you can easily pick up 6-7" panels for around $30 on aliexpress/ebay.

except they are charging 350 euro even for 6 inch, and you can buy a hackable 7.4 inch panel WITH a radio mcu/ battery/ case/ etc... for $40

I mean sure if you don't mind the fact that ESLs tend to have horrible resolution. The chroma 74 you linked, for example, only displays 640x384 for a 7.4" panel. Good pick if they work for your application.

Depends on your viewing distance. If viewed from a few feet / a meter, that resolution is probably enough. The contrast ratio might be the bigger problem. From a low-effort search, photo paper has a contrast ratio of 100:1, while e-paper has a contrast ratio of only 12:1. Photos displayed on e-paper are going to look washed out.

thanks to lack of very rough pixel boundaries, eInk looks quite goods even at that res, actually. Photos looks perfectly fine, eg: http://dmitry.gr/images/chromaGrey.jpg

If you want to hack it and don't want to pay for consumer grade quality for neither hardware nor software, then the device you linked is a good choice.

[dmitrygr]

e-Ink price tags are designed to be used and abused by store public who do not care about store property. They are built like tanks, so "consumer-grade quality" would in fact be a downgrade...

You can get old stock of the 9,7" panel at around 30$ each.

Can you provide some links where I could get this? I would be interested at this price point.

I would also be interested in some links. That seems interesting and reasonably priced.

Something slightly larger would also be exciting. The 13.3" (replacing an 8.5x11 sheet of paper) from the article would be awesome.

I sure wonder for how much longer supplies are going to last. Those screens are from/were meant for the second generation Kindle (DX) that is over a decade old now.

Unfortunately there's no such offer on larger or color screens yet ... maybe one day.

According to this page, those displays are not the best; https://github.com/vroland/epdiy

Thanks.

It claims that that supplier does not ship to the United States. Is there some way around that?
