Crack a Combination Lock In 30 Seconds With This 3D-Printed Contraption

A few weeks ago hackerSamyKamkarshowed the earth how toeasily crack up a Master combination lock — the same form used on thousands of school lockers — in eight tries or fewer . But who has the time for that ? gratefully , Samy has keep up up with thiswonderful 3D - printed contraptionthat does all the hard work for you , in about 30 seconds .

Samy encourage anyone tobuild a Combo Breaker for themselves , and has posted detailed teaching , as well a step - by - pace picture , on how to assemble the $ 100 worth of parts that went into its universe . You ’ll need access to a 3D printer to create the frame , but the stepping motor motor , Arduino Nano that serves as this contraption ’s brainiac , and other necessary components are all promptly usable online .

When left to its own devices the Combo Breaker can take upwards of five moment to crack a Master compounding lock . But if you ’re willing to serve it out by finding the first turn on the telephone dial that devote some resistance ( as outline inSamy ’s tutorial from last month ) the crack appendage can take as little as 30 second . So if this little machine does n’t encourage Master to fix the design defect that makes its combination locks so well-situated to collapse , nothing will . [ Applied HackingviaWired ]
