Not sure what you are looking for, but Steve Ciarcia of
www.circuitcellar.com had some biofeedback stuff a long time back. It
would have been in Byte or Circuit Cellar. It was a box that
interfaced skin electrodes to a computer.

Not something to fool with - you can kill yourself really easy with
miniscule currents and voltages once you get past the skin resistance.
His article discussed some of the details. His machine was battery
powered, optoisolated and took that stuff into account.


P.S. if you like this group, you'd probably love Circuit Cellar
magazine too (just a satisfied subscriber since the third issue.)
