    This is a pretty nifty little board.

    For those of us living 3.3v lives, from what I can tell the audio and envelope outputs seem to work fine when powering the board with 3.3v, but the gate output gets a little sketchy.

    The Android app that comes with the Mindwave Mobile didn’t work at all, I tried it on a few phones without success. Neurosky support thought that it was possible that my Android operating system was not compatible.

    Overall, I don’t think using the Neurosky Mindwave product yields any data that is very useable. I look forward to trying Neurosky’s next revision, and I am really looking forward to trying OpenBCI!

    Kudos to sparkfun for this very honest statement in their tutorial for this product:

    Just in case it helps…

    Using an Arduino Due with the prescalar value set as in that thread I’m able to sample every 10us (verified via oscope). That’s plenty fast for the frequencies you’re trying to capture.

    Good luck!

    Bought it, loaded it, ran it, like it!

    FWIW - I have the same noise level (ave of ~60) but that’s easy enough to cancel out in software. Not sure why it’s such a big deal if it’s so consistent.

    What I’m now wrestling with is whether I can easily reroute the digital pins to allow me to try this stacked with an LCD shield for spectrum eye candy. Maybe I’ll just wire up a protoshield with these same chips but jumper pin holes for the 4 used I/O’s would have been nice. Cutting the trace is easy, soldering in a new connection not so much.

No public wish lists :(
