Every machine has its own acoustic signature – a precise frequency that indicates whether that machine is operating at peak performance. GE engineers monitor and record these sounds to perform real-time diagnostics on airplane engines, locomotives, power turbines, and medical equipment. Musician Matthew Dear and GE Acoustic Engineer Andrew Gorton teamed up to collect and compose thousands of audio emissions from the world’s most powerful machines. The result is an original track of music titled “Drop Science.”
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.
