Combination locks are no match for this Arduino-powered cracker


If you need a reminder not to put your complete trust in standard combination locks, here it is. Samy Kamkar, who once also engineered software that can hijack drones, created a motorized lock-cracking device called "Combo Breaker." We don't exactly know what he's going to use it for, but it's capable of going through each combination in less than two seconds and can crack a lock open in no time. Kamkar created two versions of the device: one is smaller and slightly less powerful than the other, but both are equally effective, in part thanks to their Arduino microprocessors. Before you head out in search of a better lock, though, watch Kamkar explain how he built the machines after the break.
