Joel Murphy (co-creator of the nifty PulseSensor, an Arduino sensor that detects pulse) teamed up with Conor Russomanno to create the OpenBCI, a Bluetooth-enabled, Arduino-compatible, 8-channel EEG platform that gives you access to high-quality, raw EEG data. What can you do with it? Biofeedback, DIY sleep research, creating art, controlling systems, and more.
They’ve got a Kickstarter going to fund it.
