When a new pair of prototype Adidas sneakers wears out after a couple of years of use, you can put them in the sink, add a small packet of an enzyme, and naturally dissolve the shoe upper. Within 36 hours, you can safely rinse it down the drain.
The shoes, made with an extra-strong, nature-inspired new material called Biosteel, are designed to take the idea of closed-loop products one step further: If they make it to the market, you’ll be able to recycle most of the shoe inside your own home. (The sole, at least in the prototype, is not made from the new material.)
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.
