We've shown you a calculator that can help you crack a master combination lock before, but this device will do all the work for you in under 30 seconds.
In the video above, Samy Kamar, the same guy that came up with the combination lock-cracking calculator, has found a way to take things to the next level. Using an Arduino Nano, a small motor, and a few other electronic parts, you can build a battery-powered contraption that will crack any Master combination lock in under 30 seconds. Putting it all together is quite the process, and involves 3D printing a few pieces, but the end result is pretty impressive. Fortunately, 3D printing doesn't cost an arm and a leg anymore, and there are a lot of services that can print things for you too. If you've ever wanted to feel like a super spy or master thief, this is the device for you. You'll never have to worry about forgetting your combo ever again! You can find the complete guide with the source code and 3D models at the link below.
