It would be fun to build a USB puzzle box. Here is how it would work after you plug it in:
- It would illuminate it’s buttons in an entertaining pattern
- If you punch in the secret code it would unlock it’s storage drive
- If you punch in the wrong code it would reboot your computer
It is supposed to be fun. I haven’t thought too deeply about this, but it is supposed to be fun no encryption or anything. The security comes from the device simply not even showing up as a storage device until you “unlock” it.
Since I’m on OS X, this seemed like a good place to start.
