> and screen burn-in was definitely an issue. I find this very surprising, I was aware that you can sometimes get ghosting-effects, but I did not think permanent burn-in was possible on EINK tech.

Burn-in is very possible. It is ink particles inside a solvent. Drive it the wrong way and you'll damage the ink or the solvent. Just like LCD where if you drive it the wrong way, the liquid crystal gets damaged. The difference is LCD voltage waveforms are built into hardware and are much simpler since there's no moving components.

Thanks for the insights

That is not battery powered and judging by the lack of side photos I imagine it is unsatisfyingly thick.

There are more pictures here https://shop.invisible-computers.com/products/invisible-cale...

Ah ok it does look thin enough. Still a bit hard to tell tbh. Why no photos of the back?

If they made a battery powered one I would buy it.

Well done! I wish something hackable like this was commercially available (without surveillance/data harvesting.)

Check out LILYGO T5 4.7 Inch E-paper based on ESP32 for $33: https://www.aliexpress.com/item/1005002006058892.html Or you can repurpose an old Kindle: https://github.com/matopeto/kindle-weather-dashboard

I actually just got one of those devkits, it was only slightly more expensive to get this than just the eink display. and there is ready to go weather display software already available.

You can also use the built-in web browser without jailbreaking Kindle: https://github.com/matopeto/kindle-weather-dashboard or my https://github.com/niutech/kindle-dashboard

That's a good option, but it does leave the browser UI on the screen.

Could be an opportunity to build a custom case hiding this bar

If this kind of device would come in 'off the shelf' ready to go, I'd buy one. I think e-Ink screens are really attractive to be hung on the wall. I hope we're going to see such device come to life; my bet is some successful kickstarter followed by an amazon clone with alexa built-in :vomit-face: +1 for a simple device that does one thing, and does it well.

I must spend at least a couple days a year for the last 15 fantasizing about having a wireless information radiator like this.

The idea first came to me in the era before BYOD was an okay thing. It was a huge struggle to put anything on the network, like a board saying how broken the builds are. And punching holes in walls or having dangling cables is always a problem, even at home, hence wireless.

eInk is pretty much the only candidate for a device that sleeps most of the time and wakes up momentarily to poll for data.

>The picture is from the library's electronics room which has cool gear such as laser cutter, 3D printer, and much more. Amazing! I've never seen anything comparable in a U.S. library. What a wonderful resource. How do they maintain it?

I live in MA and we have this. Our library has a whole maker space including a 3d printer where you just pay for the filament

what town in MA are you? I'm in Shutesbury, and we're building a new library in the coming years. would be great to do this, and have an example to base from.

I've never seen these, do you know of any in Sydney? A quick Google turns up some 3d printing services in other towns/cities but nothing like this

Darling Square has "The Exchange"[1] which has Solder stations, 3D printers and a laser cutter but I'm unsure how to book time with them. Might be worth giving the library a call. [1]: https://www.cityofsydney.nsw.gov.au/talks-courses-workshops/...

Somehow missed this reply, but thank you!
