Hi there. I'd love to hear what you find. I'm a sporadic (but always enthusiastic) self tracker, and now also anthropologist researching the quantified self community.
I'm waiting on a Melon EEG, which had far fewer sensors than the Emotiv. But I'm a (sometime) Zen practitioner, with a neuroscientist boyfriend, so if I can help get your experiments up to n=2 I'd be delighted to help.
