Ah, passwords. Regardless of what system you use, they’re a pain in the arse to manage, remember or access. But maybe there’s a solution. What about making a USB dongle that enters and creates new passwords every time you plug it in?
Joonas Pihlajamaa decided to give it a try, and put together this little USB drive. Every time he plugs it into a PC, it enters his password. Tap Caps Lock four times in succession, and it generates a new password ready for next time.
To make it, he gutted a USB stick and created some new circuitry using an Attiny chip, a handful of resistors, a couple of diodes and a scrap of breadboard. It looks easy enough that I could do it — which says quite a lot.
