I've been sitting on the idea of putting several of these tags around the house and have them display quote, jokes, and facts.<p>The best guide I've found so far is this one [0], as it uses easy to procure tags + guides on GitHub + offers an application to auto-upate tags via screenshot area of a website and <i>seems</i> like it could be done in an afternoon.<p>However, I'm hoping to find an even more streamlined approach that I could turn into a gift to others (assuming they want a 3rd party device on their network), where the tags sync to a raspberry pi (or similar cheap USB powered device), and it uses very cheap tags, if anyone has done this or has plans.<p>[0] <a href="https://youtu.be/BCkMu57S_YA?si=BsSXEladdZHvcC57" rel="nofollow">https://youtu.be/BCkMu57S_YA?si=BsSXEladdZHvcC57</a>
I found this a couple months ago and it was an amazing resource (thanks dmitrygr)!<p>I ended up using atc1441's base station firmware[0] because it's a bit of a pain to actually pop open the case and get the programming pins on the Chroma 74<p>[0]<a href="https://github.com/atc1441/E-Paper_Pricetags">https://github.com/atc1441/E-Paper_Pricetags</a>
Bookmarked for future reference! Awesome work.<p>Furrtek has been playing with those things too.
Maybe he knows things you don't and vice versa.

I wish there was a self-contained e-ink 10 inch screen that would just sit on my network and accept URLs to display in sequence. Possibly with an equivalent to a Raspberry Pi 3 to SSH into.
This is one of the best firmware-related technical writeups I've ever read on HN. The author doesn't overstate the nightmare that is 8051. I can personally vouch for its horribleness, and its cockroach-like persistence.<p>As a hobby photographer who mostly shoots black-and-white film, readily available info about generating grayscale images on eInk displays is intriguing from an artistic perspective.
