Ever look at a graffiti wall and wonder what would happen if you scraped off a bit of paint? Well, Imgur user Paul De Graaf saved you the trouble by chipping away at a wall of graffiti in the Netherlands. This is what he found.
Over 30 years of paint caused an incredibly colorful stratification that is almost like reading the rings on a tree trunk. The hardened layers of paint form a vivid timeline all the way back to the 1980s, when this space in the town of Nijmegen became a center of art and music. De Graaf has even cleverly created a visual look at history using the paint itself. In this case, walls really do talk.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
