First, what is the role of that current sensor in the circuit? Second, is there a good trick for optimizing a brute force approach like this? We’ve seen mechanical peculiarities of Master locks exploited for fast cracking. For now, we want to hear from you on two things.

The gamification of the project has to do with a pair of $100 giveaways they’re doing for the closest guess on how long it’ll take to crack (we hope it’s a fairly fast cracker) and what the actual combination may be. The overall framework is built out of aluminum channel which is affixed to the safe with rare earth magnets - a very slick application of this gear. The dial and lever both have 3D printed adapters to interface with the rest of the system. There is what appears to be a reflectance sensor above the dial to keep precise track of the spinning dial.Įlectrically this is what we’d expect, but mechanically we’re in love with the build. This will keep us guessing on the use of that INA169 current sensor that plugs into the safecracking shield. We say “presumably” because they’re not publishing all the details until after it’s cracked, a process that will be live streamed starting Wednesday. There is a piezo buzzer to indicate success, and the board as a display header labeled but not in use, presumably to show the combination currently under test.

The SparkX (the new rapid prototyping endeavor at Sparkfun) approach was to design an Arduino safe cracking shield. It has a motor driver for spinning the dial and can drive a servo that pulls the lever to open the door. We’ve seen enough reddit/imgur threads to not care at all what’s inside of it, but we’re all about cracking the code. wife picked it up on Craig’s List cheap since the previous owner had forgotten the combination. The origin story of the safe itself is excellent.

They just put up this safe cracking project which includes a little gamification. Looks like is making awesome the focus of the R&D push he’s driving at Sparkfun. We love taking on new and awesome builds, but finding that second part (the “awesome”) of each project is usually the challenge.
