Grove GSR Map "dowser's" lie detector

[Mike(Mont)]

I got a Grove GSR for an Arduino. It cost me $15. with shipping (You will need an Arduino and USB cable--about $10 for a counterfeit). Basically this is an electronic pendulum. Anybody having trouble using pendulum you might consider getting one of these. And it can help you learn the dowsing response. Really helps eliminate the distraction of holding the pendulum steady so you don't influence the outcome nearly as much.
