Ask HN: I'd like to dabble with brain computer interface, recommendations?

Be prepared for some noisy-heavy signals. I haven't experimented around with enough different acquisition methods to recommend a particular device, but each one is going to have their own challenges (either $ getting them or some negative signal quality issue).
Once you have a system there should be some basic demos with regards to observing a few EEG bandpower based estimates. Beyond that I would recommend looking at SSEVP (steady state evoked visual potential) as all of the conference papers/talks/posters/etc about that topic make it seem reasonably approachable compared to other tasks, being EEG (rather than LFP) friendly (IIRC), and it makes for some cool applications.

What do you want to do?
There's http://openbci.com/ but I was wondering if there's a cheaper way to get started. Thanks
