It is the CS:GO bomb, to activate it you had to enter the password "3755608", if it was wrong a text with "Try again would appear". If the password was correct it would start the countdown. Depending of the wire you unplugged the bomb would defuse, explode or increase the countdown speed. Unfortunately i don't have any videos with it because i had to return the components to the school :(.
