I’ve always been fascinated by keyboards and the various types of materials and switch technologies that underlie them. This Instructable shows you how to make a cool-looking wallet out of the flexible circuit material used in the typical keyswitch assembly.
It sounds like it’s not the easiest cut n’ fold job you can do, but it looks like you get a very unique, and uniquely nerdy, bit o’ kit out of the effort. Hey, I need me a new wallet. Maybe me and my Leatherman will get Medieval with one of the half dozen old boards I have gathering Radon in the basement.
