How to compose classical music with your brainwaves
This new project from Professor Eduardo Miranda allows you to compose music with your brainwaves, from bbc.
Joel told me the main electrode at the back of my head would pick out brainwaves from my visual cortex while the other electrodes would essentially help to cancel out any background noise.
Operating the device requires the user to concentrate on one of four chequered patterns. These all flicker at different rates and each pattern makes the visual part of the brain create a sympathetic electrical signal.
The signal gets picked up by the brain cap and sent to the computer. The device works best when the rest of the brain is relaxed, so “clearing your mind” is encouraged.
The brain’s electrical signals are amplified then sent to a laptop.
Joel encouraged me to stare at the pattern in a very particular way, a bit like focusing and defocusing. Sometimes I’d have to look away from the screen and look back to refresh my brain.
We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
