Nic Wallenberg’s Human Speaker collar turns one’s mouth into a speaker. Our throats produce sound by one’s vocal chords reacting to air from the lungs, and the resulting sounds then being amplified by the mouth. Wallenberg’s device bypasses the vocal chords and transmits vibrations directly into the upper throat. Wearers can play with the music they emit by moving their lips and mouth. Each collar can produce up to two music notes at a time, so the more people using the collars together the more complex the compositions can become.
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.
