[EEG] open eeg/ocz nia "success"

[Josh Bailey]

Right on. I'm open to some arm twisting to contribute my boards to the 
common cause, since two channels are pretty boring. :-)

I have some ML and some signal processing skillz, and some software, and 
some generic electronics/electrical engineering... would love to help out 
if I can.
