Analysis of EEG signals

Michal Oblastni published a Jupyter Notebook for EEG signal analisys. Here are his comments:

For data collection, just attach a wire or a small metal object to your head. It will have conductivity.

When voltage from your scalp is conducted through a wire, amplify it from microvolts to millivolts, and convert analog millivolts to digital information.

Finally, expose digital information as bytes of data via a USB controller for a computer to be able to see the measured voltage. Different positions on your scalp have different voltages depending on electrical https://en.wikipedia.org/wiki/Cell_signaling.

EEG-SMT measures voltage 256 times per second. It’s only a 2 channel device, hence suitable for a PoC.
