Wondering if you have by any chance shared code and plans for the long battery life setup? Mine is still wired but I'm thinking of using ESP32 + deep sleep.

- sho_hn 3y agoI _still_ haven't set the GitHub repo to public :( Real-life intruded in a major way (first baby). esp32 + deep sleep + external RTC is what this is using. I posted some of my experiences with getting it as low as I could here: https://news.ycombinator.com/item?id=37663913 https://news.ycombinator.com/item?id=37663913 Here's a few more pics: https://imgur.com/a/NoTr8XX https://imgur.com/a/NoTr8XX I found the mention of Blue Noise Dithering in this project quite interesting! I've not put a lot of effort into picking the nicest possible dithering method (just a basic Floyd-Steinberg) for the embedded article photos, partly because the whole newspaper look didn't seem to warrant it, but it might be worth taking stock of what the latest on dithering is.
