For people complaining about price, large eink panels are insanely expensive. The cheapest 13.3&quot; panel with a min order of 1 is around $400-450. That&#x27;s for a panel with no driver board. If you&#x27;re interested in an easy diy approach, you can pick up a 10&quot; 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&quot; panels for around $30 on aliexpress&#x2F;ebay.<p>[0] <a href="https:&#x2F;&#x2F;www.waveshare.com&#x2F;product&#x2F;displays&#x2F;e-paper&#x2F;epaper-1&#x2F;10.3inch-e-paper-hat.htm" rel="nofollow">https:&#x2F;&#x2F;www.waveshare.com&#x2F;product&#x2F;displays&#x2F;e-paper&#x2F;epaper-1&#x2F;...</a>

That is <i>surprisingly</i> good contrast. Better than I&#x27;ve ever seen e-ink displays produce, and I have on occasion been looking - I&#x27;m a photographer and enjoy hanging my own work, and it would be convenient to do so this way.<p>On the other hand, for the same price as the 13.3&quot; version and at the same size, I could print and frame approximately 80-100 photos, even from my gallery-quality inkjet - if I take the quality hit and use the HP AIO where the ink is free, that&#x27;s about 200-250. (At that point it mainly depends on what kind of bulk rate I can get on the frames!)<p>So the unit economics don&#x27;t really work out in favor of the ArtFrame here, I feel like. I wish they did!

Very HN question, but are they hackable? I&#x27;d love one of these as a daily calendar; I&#x27;ve used an old&#x2F;decrepit Kindle before for the same sort of thing, but something like this would be much more attractive.<p>I could assemble something myself, I guess, but I&#x27;ve got other projects taking up time and don&#x27;t mind paying a little bit to turn the physical assembly problem (I&#x27;m bad at) into a mostly software problem (I&#x27;m mildly better at).

I love e-ink and these look really cool, but yeah, that price. Where are you currently getting your displays? You may be interested in EPDiy [0] (controlling cheap left over Kindle DX screens with an ESP32) and Inkplate [1] for some inspiration on cheaper sourcing.<p>For reference: the 6&quot; Inkplate costs around 100€ and I think you could fairly comfortably build a 10&quot; EPDiy device at around that. That&#x27;s without all the fanciness of course, with it I reckon it should be possible to sell these things at around 200€ each, which would probably make them a lot more interesting to people.<p>That said: I&#x27;m excited for color e-ink screens appearing on the market. The amount of devices released lets me hope at least some will make it to a secondary market.<p>[0]: <a href="https:&#x2F;&#x2F;hackaday.io&#x2F;project&#x2F;168193-epdiy-976-e-paper-controller" rel="nofollow">https:&#x2F;&#x2F;hackaday.io&#x2F;project&#x2F;168193-epdiy-976-e-paper-control...</a> [1]: <a href="https:&#x2F;&#x2F;inkplate.io&#x2F;" rel="nofollow">https:&#x2F;&#x2F;inkplate.io&#x2F;</a>

350 euros for 6 inch? 450 for 9 inch‽‽<p>Just buy some very cheaply-available electronic price tags [1] and use open-source firmware[2] which supports greyscale + yellow. Save literally <i>HUNDREDS</i> of dollars&#x2F;euros&#x2F;etc. For extra credit, they are not only black and white eInk screens, they are BWY, so they can add a splash of yellow!<p>[1] <a href="https:&#x2F;&#x2F;www.ebay.com&#x2F;sch&#x2F;i.html?LH_Auction=0&amp;_nkw=Chroma74" rel="nofollow">https:&#x2F;&#x2F;www.ebay.com&#x2F;sch&#x2F;i.html?LH_Auction=0&amp;_nkw=Chroma74</a><p>[2] <a href="http:&#x2F;&#x2F;dmitry.gr&#x2F;?r=05.Projects&amp;proj=29.%20eInk%20Price%20Tags" rel="nofollow">http:&#x2F;&#x2F;dmitry.gr&#x2F;?r=05.Projects&amp;proj=29.%20eInk%20Price%20Ta...</a>

I would love a SIM variation of this -- where instead of uploading pictures via the frame&#x27;s wifi hotspot, I could send the frame to grandparents and upload online and they&#x27;d get downloaded onto the frame via international SIM card.

For that price I would expect a much nicer frame. Looks like it is plastic.

Too expensive. Can probably buy several dozen nice color prints for that price and swap them manually. Sure you lose the tech &#x2F; geek factor but for that eye-watering cost, I think it’s worth it.

Are the listed dimensions correct?<p>On the <a href="https:&#x2F;&#x2F;framelabs.eu&#x2F;en&#x2F;technische-daten&#x2F;" rel="nofollow">https:&#x2F;&#x2F;framelabs.eu&#x2F;en&#x2F;technische-daten&#x2F;</a> page both the 6″ and the 9.7″ is listed as being 222×309 mm, which is roughly the size of DIN A4.<p>On the <a href="https:&#x2F;&#x2F;framelabs.eu&#x2F;en&#x2F;artframes&#x2F;" rel="nofollow">https:&#x2F;&#x2F;framelabs.eu&#x2F;en&#x2F;artframes&#x2F;</a> page, however, there&#x27;s a clear difference in size between all models.<p>Could you check the sizes, please?

I made a photo frame for my mum out of my old iPad, just found a frame the right size and stuck it around the edge. So long as you keep it plugged in it works great. The family just adds images to a shared iCloud library and they appear on there automatically, in full color, and it cost me just the frame and not getting the pitiful recycling &#x2F; resale fee for an old iPad.

Reminds me of that time someone posted a similar project with an e-ink display showing the current newspaper... and the screen itself was over 3k

A very relevant thread from four months ago about why e-ink is so insanely expensive: <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=26143407" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=26143407</a>

Too expensive for me, but love the idea, they look awesome!

I can&#x27;t help wondering just how small the market is for a 13.3&quot; panel at 900 Euros. I would guess there are less than 100 customers.

These are beautiful. But also ridiculously expensive.
