…the ultimate goal is not music. It’s language. Schalk dreams of letting people speak with their neurons, issuing silent commands to their machines. You could imagine the word “cat,” say, and it would pop up on your computer screen. The areas involved with imagined speech take up just a few centimeters in the brain. With better implants, Schalk said, he might be able to pick up a word that his volunteer beams at the computer. Even with today’s implants, he and his colleagues are getting closer. One epilepsy patient moved a ball across a computer screen simply by imagining either an “ooh” sound or an “aah” sound. It marked one more step toward telepathy with machines.

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.
