What do you do when you forget a 3 number combiniation where each number could be 1-100? byte sized engineering works up this stepper motor solution with a bit of Adafruit gear!
This is just part 1, follow along to see if they get the safe open!
He sat down for hours and hours trying all the different numbers he could think of to no avail. The safe has been sitting locked in his house for more than two years! That’s when Levy called me. There are 100 numbers on the dial, and the combination has 3 numbers, so there are a total of 1,000,000 possible combinations! There is no way someone could try all of those by hand; that would take several lifetimes. But if I can find a way to test combinations quickly (and maybe find a way to reduce the number of possible combinations) this might be doable!
I’m not a locksmith, nor do I have any burglar skills, but I am good at engineering, problem-solving, and building things, so I’m going to try to build a robot that can crack the combination to Levy’s safe.
