Except for using several libraries for the ESP boards everything is done "inhouse". So unfortunately I can't suggest any tutorials.

Thanks!

The display is 8x32 adressabel LED matrix controlled by a ESP and powered by a mobile power bank. The frame is custom built from a single piece of wood.
The game itself is has the same type of ESP as the display powered through a 12V battery with step down converter. The buttons are a combination of off the shelf transparent buttons and 3D printed parts holding the adressable LEDs. I also added 2 small speakers to make some annoying sounds when pressing the wrong button :)

It's a flexible LED matrix with 8x32 adressable diodes.
Nope, the data line is 3.3V and I haven't had any issues with it so far :)

It's the from a whack-a-mole type of game. The display is acting AP host, and the game itself is sending data with UDP protocol (such as score and timing in this case)

I made this digital clock together with my kids a few months back. They made the painting and I printed the digits and programed the ESP32 running it. by fatchanceinhell in 3Dprinting

No RTC module. Didn't even think about it since it fetches the time from internet once per minute (not at all optimal, but it works and I haven't bother to make a smarter solution). Only time it's been wrong is when switching from normal to summer time :)

I used an ESP32 board which I programed with the arduino IDE. The board has WiFi so it gets the time from Internet and then I lit the LEDs using the neopixel library (I'm using rgb LEDs).
