       | How have they managed to get such smooth video/scrolling on an
       | e-ink screen? All the other things I've seen have this jarring
       | black flash every refresh.

         | The flash kind of "resets" each pixel. You can update without
         | the flash (and some e-readers support this) but artifacts
         | slowly accumulate.
         | 
         | In the video they show a mode where it is B&W while scrolling,
         | but after stopping the scroll it flashes and renders in gray-
         | scale. The narrator mentions several possible modes; noting
         | that 16-shade gray-scale is too slow for any interactive use
         | (including typing), but 4-shade can allow typing and B&W can
         | allow fast scrolling &c.

       | Are we talking $300 or $3000?

         | be found on AliExpress for a bit below 200usd.

         | Given that a 13in e-ink display is 450$ by itself[1], and the

         | For the complete monitor, a 13.3 e-ink screen alone has a
         | retail cost of around 350-400 USD depending on where you look.
         | There's also the FPGA and other components.
         | 
         | We have commercial displays of similar size available around
         | 800 usd. So, adding up the manufacturing, development and other
         | overheads my guess is it could be around 1000 USD.
         | 
         | The dev kit should cost less if we can source the monitor &
         | enclosure ourselves.
         | 
         | I didn't go through the complete list of supported hardware but
         | if we can get the dev kit work with old kindle or kobo 6"
         | displays it should be an interesting diy to work on.

       | I'd love to have one, I have glare issues at work and home where
       | this would hopefully help, being unwilling to simply black out
       | the window.
       | 
       | I like having both a sky, and somewhat changing digital artifacts
       | in my field of view.
       | 
       | A minor concern is that there are so few supply chains for the
       | underlying technology. This is a bit like "that screen really
       | came from Samsung like all the others" or the more real world of
       | where disk platters come from (Thailand, for almost everyone, at
       | one point if not continuously)

         | From looking at the demo, you might still have glare issues.
         | You want this display if you'd like one that goes easy on your
         | eyes.

       | 13.3" but the github page lists some alternative, larger
       | displays. Supports some interesting interfaces. Seems to need USB
       | PD power so it sounds power hungry. Regular 5 volt USB would be
       | nice, for this to be a good companion display to a Raspberry Pi
       | or the like. Otoh it sounds like the complete monitor will cost
       | around $1K based on comments below.
       | 
       | I'm still mostly interested in an Inkplate 10 though 13.3" is a
       | better size for an e-reader. For a desktop monitor I really want
       | 20" or larger. For E-ink that would be super expensive.

         | Also, it seems like large panels could be relatively power
         | hungry, at least on peaks, to be powered by a classic 5V USB
         | brick, when the standard is limited from 55mA to 1.5A (rarely)
         | [0].
         | 
         | The CrowdSupply page says it includes an "E-paper power supply
         | with up to 1 A peak current on +/-15 V rail supporting large
         | panels sizes".
