Currently, BOM cost is higher than that, I believe. But we can hope that with devices like the Remarkable bringing larger format e-ink that the pricing can be driven down with process improvements that come from scale.
This can be done on a smaller form factor at around 400 Euros with the reMarkable tablet, see [0].
Thank you so much for that link! I just got my reMarkable2 (which I adore) and this is quite useful. Both by itself as well as for hacking pointers. Being able to use my reMarkable as a static eInk display of a content of my choice is so useful, something I always missed with my kindle.
The screen itself _is_ a commercial product. The custom software to run this is only a few dozen LoC on a server and you could probably work out how to hack it directly with the Visionect software.
An e-reader of that size would be much more expensive.
i would love this as an art piece.
if you were willing to make one to sell i would buy it.
