Maybe I've been living in a cave but I had no idea that tech like NeuroSky and emotive was so cheaply available. Anyone with experience on which one is better?

I don't have either, but I'd go with Emotiv... theirs has more sensors. Recommended watching: http://www.ted.com/talks/tan_le_a_headset_that_reads_your_brainwaves.html http://www.ted.com/talks/tan_le_a_headset_that_reads_your_br...

I can't speak for the NeuroSky, but I reverse-engineered the protocol and crypto used for the Emotiv to create the open source Emokit ( https://github.com/daeken/Emokit https://github.com/daeken/Emokit ) a couple months back. While no one has really done anything with it yet, it opens up some fun stuff. The Emotiv has the benefit of more sensors, and it isn't much more expensive. I'd love to see someone do something really cool with it.

  I just found that 20 minutes ago and was so excited that I ordered an Emotiv right away. Great to see that you're an HN user, I'm looking forward to playing with the Python library.

    Awesome. Feel free to hit me up on #emokit on irc.freenode.net. One note: the new headsets may have a different key than the older ones. This has not yet been confirmed, but if it is the case, I'll get it working again regardless.

  Nice! Does this mean that Emotiv doesn't have a developer-friendly API? NeuroSky seems to really emphasize this.

    1) Their API is Windows-only (they have Linux support in beta, though) and is expensive as hell, and 2) The API to get raw access to the EEG data is $750 bare minimum. Silly, considering the consumer and developer headsets are identical, outside of the AES key used.

  Do you have a writeup anywhere detailing your progress and/or what is capable using the api you have created so far? I'm super interested in this I just want a little more to go on than is in the readme. For example, it's not even clear to me if I need to buy the regular headset (299) or developer headset (500)
  - daeken 16y ago
    No real writeup, but as far as what's possible: all data coming from the headset (gyro, EEG, contact quality, and battery meter) is accessible from Emokit (although the latter two are not merged into my branch yet). This means that you can do effectively anything you want with it. Also, you only need the regular headset, although it's compatible with the developer headset as well.

  Thank you so much for doing this. I've delayed getting one because of the cost of their "full" API. I'll definitely get one now!
