ECG/EOG/EEG experiments

I'm a backer of OpenBCI  but they still haven't delivered.
(Other people have, 3 days ago)
So I just ordered myself a "Shield-EKG-EMG" from Watterott.

I managed to get my heatbeat.
(That's the easiest you can do.)
Next step shall be tests of Electro Oculography (electric eye tracking).








Just some notes for myself:



EOG

Signal is in the range of 1mV peak to peak .
Eye-blinking artifact is very strong.
50Hz line noise must be removed (of cause). (notch fiter)
low-frequency cutoff to 0.02 Hz
high-frequency cutoff 50Hz
