Building an Escape Room Lockbox with the ESP32 Cheap Yellow Display (CYD)
Here’s something fun from [Chad Kapper] over on HackMakeMod: Escape Room Lockbox with the Cheap Yellow Display.
You may have heard of the “cheap yellow display” (CYD), so-called due to the board’s typical color. It’s a dodgy cheapo board with, among other things, TFT display, touchscreen, and ESP32 built-in. You can learn more about the CYD over here: Getting Started with ESP32 Cheap Yellow Display Board – CYD (ESP32-2432S028R).
In this build eight AA batteries are used to deliver 12 volts to operate a solenoid controlling a latch and 5 volts for the microcontroller. The encasing is clear in order to entice players in an escape-room style sitting. The custom software is included down the bottom of the project page and it is also available from arduino.cc, if that’s your bag.
Of course we’ve done plenty of other ESP32 TFT projects before, such as Piko – Your ESP32 Powered Fitness Buddy and ESP32 Brings New Features To Classic Geiger Circuit.

@stefano Wow. Just ... Wow. Well handled on your part!

We report in the pink few minutes of sunrise. In the morning, the sun veers more and more northeast from its wintry southeast position - although it is not any warmer that we can tell. We follow a host of sparrows from tree to tree as we are trying to dodge a very thin drizzle.

@lokeloski GenAI is like a filler, like Bondo. It can take something roughly shaped like the thing you want and smooth it out in all places - but at no point will it actually create things. And like many car fixers that start using filler will tell you, if you use a lot of filler you don't end up with anything functional.
