The Quite Rubbish Clock #piday #raspberrypi @Raspberry_Pi
Check out this demo of the hilarious “Quite Rubbish” Clock (i.e. QR Clock) from Stewart Russell, a bit of fun poked at that darling of hipster advertising agencies, the QR Code — you need your phone or a computer decoder to read the time. (Don’t we all just use our cell phones for the time anyway?)
This is a clock built with the Raspberry Pi. It works, but it’s not readable by humans: instead, you find out the time by scanning the QR code it outputs with your phone.
Stewart Russell knocked this together not because he wanted to know what time it was (just as well, really), but because he was interested in trying to get the Pi to interface with an old surplus Nokia LCD display via SPI. If you want to have a go at something similar yourself, Stewart has all the code, wiring and parts lists you need at his blog. These little LCD displays are very inexpensive and aren’t hard to find; if Stewart’s QR clock has given you an idea for another LCD project, please let us know in the comments!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
