Sometimes its good to see what other people are up to on their projects. It can serve to spark an idea for your own designs, and this one here is just plain cool. This QR code clock is displayed on a graphical LCD screen, and is totally indecipherable just to look at. You have to take a picture of it with a QR code app to tell the time. Each second, the QR code on the clock changes to update the time. This clock is actually kind of hypnotizing to watch – check out the vid!
The QR code clock was built by Markus Gritsch over at Dangerous Prototypes, his idea built on inspiration from an earlier LED matrix-based QR clock. His clock runs on a PIC32 microcontroller which decodes a time signal from a DCF77 receiver, then calculates a QR code and displays it on the ST7735R graphical LCD at 30FPS. Markus added a layer of polish to the project with some cool effects – when the clock is unable to read the radio signal it displays time in greyscale, but when it locks to the DCF77 signal it starts to trip out with a rainbow-colored plasma effect. Nice work for sure! I wonder how long it would take you to learn to tell the time just by looking at the QR code without scanning it…
Quick question: what are you guys up to in your projects? We would love to feature the fruits of your labor here on the homeblog, so whatever you’re creating, make sure you post it to the forums. We’ll do the rest.
