It amazes me that people are always coming up with new and interesting uses for Lego, the latest is the Lego Safe.
The Lego Safe features a five double digit code lock, with over 305 billion different combinations.
Put away your valuables in this Lego Mindstorms NXT Safe and nobody ever can get even close to it! This 6,5 Kilogram heavy weight SAFE has an electronic code lock. Five double digit codes are required to open the lock. The dial (left-hand wheel) is direction sensitive. Thus 35 to the left is something else than 35 to the right. Only one out of more than 305 Billion code combinations is unlocking the door!
Here’s a video of it in action.
