Hi guys,
I've been wondering how to build a lie detector and did a bit of research on the topic. I was able to find a few ideas that were based off of the galvanized skin response (you sweet when nervous). The idea behind this is the more your swetting the better of a circuit you make (or something like that).
Anyway I was able to piece together a few different ideas. Keep in mind I have never done stuff like this but am very interested in trying to make one by hand.
Here's someone's project
Making the lie detector
I'm pretty sure following the directions that I would no problem making that, but that and pretty much all projects I've seen really on a speaker (which seems less reliable). I wanted a way to measure it more accurately. On one project I saw someone said:
"Really like the enclosure, but it'd be really cool to make an arm swing or something when it's picking up on a "lie" Add another transistor, a D/C motor, a 555, a rubber band, a coat hanger and a pencil!"
Is that really possible and if so could make a diagram or something. I figured it was simple compared to some of the stuff others do. If I had any idea of how to do this kind of stuff I'd do it myself, but as is I've got no experience.
Thanks in advance.
