Nice project!!! I love these e-ink based projects that enable you to provide data without looking it up.

Is there a way to enable real-time messaging on to an e-ink device ? For e.g. I would love to keep a kindle running that can show a message when I am on the road.

It's a pity there isn't more action in the e ink application/device world. Seems like there's so much potential. I'd love a kindle-like laptop for writing. I guess it's just extremely hard to compete for a beachhead against an incumbent (mobile touch displays) that's more general and mass produced.

My understanding is that it’s heavily controlled by E-Ink (the company). When only 1 company can make the displays and they charge quite a bit of money for them, adoption will always be difficult.

Once the patent expires I expect these to be used everywhere.

Since updating an eInk screen is relatively expensive, I suspect this system could be made more efficient by issuing conditional HTTP requests (last-modified or eTag) and only refreshing the screen when the dashboard image changes. This assumes both the ht client and dashboard server support conditional requests. The system consists of a set of shell scripts that run on a jailbroken Kindle. It includes ht, an HTTPie…

That's an interesting idea! It depends a bit on the data that is shown on the dashboard, but I guess in many cases the data is quite static. The data on my dashboard can change at any time in theory, but there are many times where the data remains the same for 2-3 hours.

This type of idea would work nice with Boox; easy to program (android) and so far the battery life has been stellar.

Might be a nice fit indeed. I considered doing this on my Remarkable 2, but it's a bit tricky to combine a dashboard with actually using the product as it's intended (for note-taking, in this case).

The advantage of using a Kindle like this is that it's cheap enough that I don't have to use it for anything else. I bought the Kindle used for €25.

Very cool. If someone is looking for a device with even better battery life: I created something similar -- albeit with a different approach to its visual appearance. See: https://framelabs.eu/en/

Can you also use it to send real-time messages ?

You can configure it to poll for messages on a fixed interval. Pushing is not possible since it would sacrifice the battery life.

What if you could build this product but to also allow for the direct power supply connection ?
