EEG in

[Frank Lemieux]

Late late last night, I was thinking once again of devious new ways to
interface myself to my synths, when it occurred to me: A mini-EEG!

I saw a setup on television a couple years ago.  There was a man wearing a
headband in front of an oscilloscope, controlling the pattern upon it.
After a while practicing, he was able to raise and lower the bias of the
signal at will.  He eventually applied this to the steering system of his
sailboat.  Cut to scene of him sitting serenely on the bow, with a knowing
grin as the boat turns on a thought...

I just keep thinking this would be so cool, to play a nice line with both
hands, and then as I get more into it and concentrate, my brain controls
resonance and as I focus it all goes into squealy heaven. :)

Has anyone done experiments with this type of thing?  I imagine it'd be
possible to DIY..  skin electrode to hi-gain low-noise amp, lopass filter
at about 40 hz to reduce hum and noise and other signals not from the
brain...  

Has anyone done anything remotely similar to this DIY?  I need a starting
point...
