The Ultracortex is an open-source, 3D-printable headset intended to work with the OpenBCI system. It is capable of recording research-grade brain activity (EEG), muscle activity (EMG), and heart activity (ECG). Link
The M3.2 is a modular version of the original M3, allowing users to print it at home with less support and more ease.
This frame is compatible with the rest of the component of the original M3 (electrode holder…).
A 3D scan of a head was used to place the electrode location and then joints were derived.
As for now, there is no attachment for the case of the OpenBCI board.
