Making a Lie Detector For a Competition
I have to make a lie detector for a competition. I was thinking about
using my Basic StampIIsx to measure the time it takes for a small
capacitor to discharge through the person's body. Is there a better way
to measure skin resistance?
-Thanks

part of the
input to the 555 for setting the time duration, so the output would have
different pulse
width's which could be measured using a Stamp.

measure chest activity and perhaps also brainwave function w/BasicStamp?
