DIY Polygraph Machine for April 1

April Fools’ Day is celebrated in many countries on April 1 every year. It is widely recognized and celebrated as a day when people play practical jokes and hoaxes on each other.

Lying is awesome way to get people fooled. Here is one idea how to avoid being fooled: use a lying detector. If you’re industrious and don’t have the dough for a legit polygraph, you can make your very own galvanic skin response (GSR) device. DIY Polygraph Machine: Detect Lies with Tin Foil, Wire and Arduino article shows you how you can build your own polygraph with Arduino board. Please note that this device is by no means foolproof.
