QR-Code Clock

Michael Ciuffo’s clever QR Clock generates each of the 1,440 daily QR codes on the fly, rather than referencing a array of pre-configured codes. His boards feature a built-in ATMega328.

[T]his clock points out the ultimate irony of QR codes which is that they are a technological convenience that really isn’t convenient. In order to read this clock, the user will require some sort of QR scanning device which is guaranteed to have a time-telling function built into it already.
