I don't know if it's just me or any of you also have this question. The bitalino revolution board read EEG signal successfully but the signal always saturated (out of range from -41.25uv to 41.25uv) when I moving (motion artifact) or blinking my eyes (eye movement artifact). Did I do something wrong in calculation or it is how it designed. I can get enhanced alpha wave when eyes shut, so the acquired signal makes sense.
I placed my positive electrode in forehead near Fp1, reference electrode in right mastoid and ground in left mastoid.
Thanks for your advice.
