He does it all: the YouTube face, the math floating around, non-working greenscreen, some memes and then he goes camping (including a Blair Witch style run through the snow). This is so brilliant.

Ouch, shade on the SensorPush. I had 2 and I got 2 more. It requires an app, but they're quite well made imho.

But yes, open source would be better. If physical portability is not a requirement, Xiaomi hygrometer 2 with this custom firmware https://github.com/atc1441/atc_MiThermometer is quite excellent

I have no idea what he's talking about most of the time but I can't stop watching.

Andrew Quitmeyer doesn't take himself very seriously, but dogs take him VERY seriously.

M5Stack has black & white (https://shop.m5stack.com/products/m5stack-esp32-core-ink-dev...) and color (https://shop.m5stack.com/products/m5paper-color-esp32s3-dev-...) development kits that look like exactly what you're looking for.

Here's one that I just ordered myself: https://www.waveshare.com/esp32-s3-epaper-1.54.htm

temperature, humidity, audio in AND out!!!

Adafruit has a pretty cool esp32 based board with a circular touchscreen and dial

Uotchi is the Japanese word for watch. Tamago (egg) and Uotchi (watch) - so here they're implying "Weather Watch", it should probably be Weatherotchi or something, but still works fine imo. Korea and Japan love smashing words together to make new words, for example in Korea "Chimaek" is Chikin (치킨 - fried chicken) + Maekju (맥주 - beer), something Koreans often ask if you'd like to go out for.

I think it's evoking "this little smiley face guy on a small monochrome screen", and not implying interactivity.

It's dumb anyway. Iirc the -gotchi part comes from the Japanese transliteration of the english word "watch". Unless your program's a pocket watch of some kind as well as a virtual pet, it's just a tama

While I'm not sure about the exact e-paper panel model used in this project, in my experience with these small e-paper screens, a full refresh is pretty much mandatory every 10 or so partial refreshes—which is significantly worse than Kindle-level performance. Just about every screen I've worked with suffers from some level of ghosting, and it definitely gets noticeably worse in higher temperatures during the summer. Plus, these cheaper e-paper displays tend to degrade quite fast—after a couple of years, the aging becomes painfully obvious.

Other comment says no wifi but even if it did, those antennas don't radiate in a straight line

It does not use wifi or Bluetooth.

It's marketing. Attach yourself to some wildly more popular brand for no reason other than to boost your own popularity. Like JavaScript did with Java.
