I doubt George Harrison had this build in mind when he wrote Here Comes the Sun but I’d like to think he’d appreciate its ingenuity as much as I do. Check out this solar-powered keyboard project from yoohsiu on instructables:
Musicians have put actual pianos in a field and play beautiful music amidst the sunshine and birdsong. I don’t own an actual wood & strings piano, but I do have a digital piano keyboard – and I can easily load my keyboard, battery, and solar panel into my small car, and take the music wherever the road goes and the sun shines. You can too! And if you do, please send me photos…!
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.
