Dolphins, along with at least 65 species of toothed whales, use the acoustic fat in their bulbous heads to translate clicks bouncing off objects in the ocean into meaningful spatial awareness. They “hear” with their jaws, which contain the same kind of fat that’s in their heads.
Marine scientist Andrew Thaler built a headset that lets you “see” the way dolphins navigate underwater: Not through your eyeballs, or by listening with your eardrums, but with faux-echolocation and bone conduction.
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.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
