The system is sensitive enough to detect the “sticky” spots of the lock, which are then used to narrow the number of possible combinations before brute forcing the combination. Their machine uses a stepper motor to turn the dial with a big solenoid to pull on the shackle. To get the combination as quickly as possible the team has implemented an algorithm discussed here. But points out that the resources we linked to before are flawed. We’ve talked about the ease with which these locks can be cracked. Here’s one of the latest, it’s an automatic Master lock combination cracker which was built by and his classmates as part of their ECE453 Embedded Microprocessor System Design class at the University of Wisconsin – Madison. We love the beginning of May because the final projects for college coursework start rolling into our tips line.
