Scientists already observe the cosmos through radio signal, optical imaging, and other techniques. A network of hundreds of solar-powered audio recorders will do the same across Australia.
Those sensors themselves will be familiar to electronic composers and field recordists. They use microphones and standard SD cards, but operate entirely on solar power – a necessity for remote locations. The recordings are continuous, and spread through the vast country, across some one hundred sites and 400 sensors covering “desert, grassland, shrublands and temperate, subtropical and tropical forests.”

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.
