PiEEG

PiEEG is an open source Raspberry Pi shield that measures biosignals such as those used in electroencephalography (EEG), electromyography (EMG), and electrocardiography (ECG). PiEEG is versatile, easy to work with, and compatible with different types of electrodes. Best of all, it was designed to be usable by anyone. To begin measuring bio-signals, all you need to do is connect the electrodes and run a Python script. Applications include gaming, entertainment, sports, health, meditation, and more.
