Twenty five years ago, physicist Robert Lang worked at NASA. Shortly after that, he researched lasers and garnered 46 patents on optoelectronics. He even wrote a Ph.D. thesis called “Semiconductor Lasers: New Geometries and Spectral Properties.” But in 2001, Lang left his job in order to pursue a passion he’s had since childhood: origami. In the origami world, Lang is now a legend, and it’s not just his eye-catching, intricate designs that have taken the craft by storm. Some of his work has helped pioneer new ways of applying origami principles to complex real-world engineering problems.
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.
