Famous for its notoriously rainy weather, Seattle is the perfect home for this new series of water-activated interactive artworks, illustrations, and hidden messages that only appear when wet. Titled Rainworks, the invisible pieces by Seattle-based artist Peregrine Church started popping up last year. Each installation is made from an environmentally safe, water-repellant coating that lasts anywhere from 4 months to a year. You can see more here.
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.
