I developed my EEG visualising pendant for use in social situations. The pendant uses EEG (Electroencephalography) signals, which are gleaned from a NeuroSky MindWave Mobile headset. The MindWave is a standalone headset device that detects electrical signals from the brain, which are accessed via a single electrode on a protruding arm from the headband. The electrode makes contact via the wearer’s forehead at the pre-frontal cortex area, where higher thinking states are dominant. The pendant displays attention / concentration data as red LEDs (light emitting diodes) beside meditation / relaxation data in green LEDs on an LED matrix. The pendant has live, record and playback functions, which give the user the choice of displaying live EEG visualisations or recording and playing up to four minutes of previous brainwave data visualisations on a loop if they’re feeling mischievous or want to appear to be concentrating / paying attention or relaxed, or just want to use the pendant as an aesthetic piece of jewellery without the EEG headset. Here’s a link to an interview with me and BBC Technology News filmed at the International Symposium on Wearable Computers (ISWC) in Zurich, Sept 2013.
Adafruit has had paid day off for voting for our team for years, if you need help getting that going for your organization, let us know – we can share how and why we did this as well as the good results. Here are some resources for voting by mail, voting in person, and some NY resources for our NY based teams as well. If there are additional resources to add, please let us know – adafruit.com/vote
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.
