This was created by using SLAC’s Linac Coherent Light Source (LCLS) X-ray laser to blast tiny jets of water to create incredible sound pressures, and it all happened in 40 billionths of a second (The research was done in a vacuum as well, so no scientists had their hearing damaged in the process). What’s more, 270dB is thought to be the loudest sound that will ever be created in the world as we know it. The reason why is that any more sound pressure would break apart the water molecules.
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.
