3-D printers have been in industrial use for more than 20 years, but their cost — sometimes reaching hundreds of thousands of dollars — generally put them out of reach for everyday customers.
That’s changing fast. Entrepreneurs devoted to the “democratization” of these devices are building cheaper versions with rapidly falling price tags. Hobbyists are testing out at-home 3-D printers and chefs are giving them a whirl in the kitchen, using the technology to create intricately designed food. Doctors are even experimenting with using advanced printers to make artificial organs and prosthetic limbs.
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, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, 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.
