[Thomas Cannon] created his own hacking game by adding some circuitry to this toy vault. The original toy uses the keypad to control a solenoid keeping the door shut. He kept the mechanical setup, but replaced the original circuit board with his own ATmega328 based internals. He also added a USB port to the front. The gist of the game is that you plug-in through USB to gain access to the vault’s terminal software. If you can make your way through the various levels of admin access the loot inside will be yours.
