I built this

It's a light-up LED calendar using an esp32 driving 8 max7219 chips to show the current date as well as some animations and a clock when you push a button (Somewhat inspired by Simone Giertz's one of course)

I'm a woodworker more than an electronics guy so I'm much more pleased with the case than the insides, though it did mean I designed my first PCB. SD card at the top stores some WiFi and time zone config data as well as the animations, esp uses an NTP library to get the current date & time and write it out to the display.

I also always wear the arms from two different sets of armour - makes me less likely to mix them up

Probably AI, based on how none of the armour makes sense

Nice

God I miss the sea... Grew up on the coast, now live in a lovely city full of trees and right next to the peak district, but about as far from the sea as you can get in this country

In my experience basically everybody in Scandinavia speaks English, you'll be fine

Good video, wrong community
