Explanation of Combination Safe Cracking

See how the insides of a common combination fire safe work. We also show a method we call Set Testing to reduce the time needed to crack the safe. The discs have a tolerance of +/- 1 digit.
Read how we built a robot to crack a safe where we had no idea what was inside. The full tutorial is at learn.sparkfun.com/tutorials/...

Clever safe design - I like the ridges on the final wheel. It looks like you are having to brute force it in the way that the designers intended which I wouldn't really say is "cracking" it. Looks like it effectively has 33 * 33 * 12 = 13000 combinations, which I guess will take you a few hours.

Looks cheap... I reckon if you hit it hard enough, It'll probably open out of sheer freight.
