Our group in the brain-machine interface lab at the other Swiss Federal Institute of Technology (EPFL), in Geneva, fielded the Brain Tweakers team to compete in the Cybathlon’s Brain-Computer Interface (BCI) Race. Gold medalist Poujouly was one of our two pilots, both of whom propelled their avatars through a racecourse by mind power alone. As with any BCI system, signals recorded from the pilot’s brain were fed into a decoding algorithm that translated the signals into commands. In this case, the commands were used to control the pilot’s avatar, but other BCI systems could be used by people with severe motor impairments to control a variety of devices—including wheelchairs, prosthetic limbs, and computer cursors.
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
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.
