Lego user builds ultra-secure safe

A Lego fan has built a tough and secure safe that is virtually unbreakable. It has a motion-detector and five double-digit codes with more than 305 billion combinations to open the safe.

With the help of Lego Mindstorm technology, a Lego user has built a 14-lb. safe with a motion-detector and numerical code lock. You can see how it works in the video above When the safe is moved without the appropriate five double digit codes, it gives off a high-piercing sound alarm. When the five codes are correctly entered, the safe opens automatically. The codes are also very tough to break, as it has nearly 305 billion combinations. The main features for this Lego Safe are: • Large Digit display (using Custom Digits, and MyNumOut routine)

• Outside dimensions 38x38x38cm, creating 30 Liters of internal storage space

• Internal safety bars prevent stone walls to be disassembled

• Automatic un-Locking / Locking of the vault (Motorized lock)

• Automatic opening and closing door (Motorized door)

• Automatic burglar alarm (using HiTechnic Acceleration Sensor)

• Variable un-locking code, set by user during locking.

• Heavy, 7cm thick, door with secret Power-On/Off buttons. The safe may look like child's play to thieves, but the safe is incredibly secure. For more information about building this safe and source files, click here.
