Raspberry Pi escape room bomb prop with Django

So, here’s a, as i think, neat little device i built for JohnDoe in Nantes (France): a bomb prop based on a RPi4B for an escape room with a Django remote control interface.

Here are a few images:

The device is programmed in Django. The players need to enter a 4-digit code via keypad. If they entered the right code, the game is won and a defuse sound is played. The remaining time is displayed on a seven segment LED display. Single LEDs indicate how many numbers have been entered and if the game has been won or lost.
The prop is remotely controlled, which allows an operator to reduce or add time to the countdown and to give the players hints. Also, the remote controls allow the operator to reboot/turn off the device, test the hardware or update the code.

Have a look at their promo video:

Special thanks to Guillaume for this interesting project and to Paul, who designed the case!
