Forget the combination to your combo lock? Well if you’ve got a 3D printer, an Arduino, a servo and a stepper motor handy — you can build your own Combo Breaker pretty easily. It’s capable of solving any Master combination lock in 8 tries or less.
The creator [Samy Kamkar] is a privacy and security researcher, who absolutely loves finding holes in security. We actually just heard from him at our very own Hack a Day Prize: Los Angeles event, where he talked about his wireless keyboard sniffer he built into a cellphone charger.
As always he gives an extremely thorough explanation of the project in his build log video — including designing the 3D printed parts! If you wanna build your own it’ll cost just under $100 and you can grab all the necessary info and source files from his GitHub.
