As brainwave-reading technology has become cheaper and easier to use, it’s begun to infiltrate the Maker Movement, enabling interesting new hacks based on brain-computer interfaces. It has even started popping up in games and toys, like NeuroSky’s Mindflex.
Father-daughter team Jeff and Megan Marinchak are hacking a Mindflex headset, tapping into the EEG data and linked it via Bluetooth to a Raspberry Pi that can show users their brainwaves in real time. It’ll primarily describe the wearer’s attention, but that translates nicely into a game, in which two players compete to focus their attention and achieve a goal.
“Often you start with a specific idea that you intend to carry out, however the final project is always a little different than you might have imagined,” says Megan, who is finishing her junior year in high school. “In this particular project we wanted to use a Raspberry Pi for the coding, however most people who were able to get the technology to work used an Arduino. As a result we had to find the best way to get our technology to work keeping in mind how much time and effort it would take.”
The project was born when a representative from NeuroSky went to visit her school. “I remember being absolutely blown away,” she says. “All those years watching TV shows where mind reading was a superpower, and here today, I was witnessing a technology that could actually read brain waves.”
