Skin Resistance

Radio Shack has sold this thing since the early 1970's. I bought it as a kit back in 1973 while in the USCG when they marketed it as a "lie detector". In 1997 they called it a "biofeedback monitor", and it came preassembled. I don't know if they still sell it, but I knew I still had it somewhere, and started to wonder how it might work while using the binaural beat technologies to force my brain into certain brainwave states.
