For those of you predisposed to paranoia, you may want to move along. However, if you’re not going to freak on me feel free to head over to Instructables to create this unique USB drive using a standard phone jack and a USB key. By assigning a pin and wire to each of the pins on a USB cable, you can create a “secure” system for storing data that you can hide in plain sight. While it’s obviously not as effective as plastering up your secrets in a basement crawlspace this looks considerably more fun and/or less illegal.
By taking a standard USB cable, stripping the four wires, and then connecting those wires to either end of a telephone line jack and port, you’ve got quite a cute little connectivity solution.
