Show HN: Building a 42-inch E-Ink frame for generative art

I'd love e-ink smartwatches, reusable/programmable name tags, fridge calendars, board game pieces (like little keepers for score, life, buffs, debuffs etc), packet handouts at conferences, whatever. Basically anything that DOESN'T need a fast refresh but could still benefit from long battery life and programmability.

I don't know if there is a big market for any of that stuff, but certainly there's not a lack of ideas. A lot of things that aren't worth it at the current price point become viable if the display weren't so expensive.

We'd all like many things, but that doesn't mean there's a mass market for them to warrant significant investments that would guarantee a decent profit for the investors.

It seems that you have a e-ink hammer so everything looks like a nail to you, but sometimes pen and paper or a plastic white-board and a felt pen are better and cheaper than a big e-ink display that needs to be recharged.

And E-ink smart watches have been made in the past but sold much more poorly than OLED one so manufacturers dropped in favor of OLED. MIP is a thing though in some Garmins.
