I know the Crowd Supply part isn't live yet but I wish this had some kind of ballpark cost, at least to an order of magnitude. Are we talking $300 or $3000?
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.
