Standing over a small tank of water in a Brooklyn factory, Zbigniew Solecki plunged a gleaming faucet into the water, then shot air at 60 pounds per square inch into it. He watched for rising bubbles, a sign that an unseen fissure had, unacceptably, let the air stream out. It is a rite of passage that Mr. Solecki performs dozens of times a day.
“Every last piece is pressure-tested before it goes out the door to China,” said Jack Abel, the engineer who built the factory. “Or anywhere else.”
Yes, he did say China.
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.
