Worried about people snooping around your USB drive? Digital encryption not good enough for you? What you need is a USB Cryptex to secure the drive from even being accessed!
Made completely out of copper and brass, [Scots72] really put a lot of effort into this beautiful piece of metalworking. The USB drive itself is encased in epoxy inside of a copper tube — the rest is built around it. Built almost entirely using hand tools, and we can only imagine how long the process took to complete. But patience is often rewarded with results like these!
[Scots72] even went to the length of trying to etch the numbers onto the copper using a resist and etch method (as described here), but unfortunately it didn’t work very well. Outsourcing the engraving was a fix that allowed him to meet his deadline. The finished product looks great. The thumb drive is anchored in a cylinder which goes in the center of the assembly, the four rotating numbered rings engage lock pins on that cylinder unless the correct combination is dialed in.
