How to make a lie detector and have some fun

Have you ever wished you would really know if someone were telling you the truth? Well, here you go. You can build your own lie detector with a few materials.

• A couple of resistors and transistors and capacitors

• A couple of double A batteries

• A circuit board

• A project enclosure

• A small PC speaker

• Some foil

• Velcro

• Wire

• Solder tool

The first thing you need to do is build a circuit board. Follow the schema in the video. You need to solder the two resisters and the two transistors and the capacitor. You then need to attach the two double A batteries. You also need to attach a small PC speaker. You should then drill some small holes in the project holder in order that you may house and hear the speakers. After putting everything in the project holder, attach it together with some hot glue.

To make the finger pad, use a small piece of Velcro and sandwish some wire and foil as in the video. Now attach a few smaller pieces of Velcro in order that the finger pad will loop around and hold securely on a subject’s finger. Now ask you questions.
It works by measuring skin resistance, which goes down when someone lies.

Go ahead, ask your boyfriend if he looked at that girl in the mall when you were walking around. Go ahead and ask your husband if he had that second beer. Go ahead and ask your girlfriend if she thinks you are the hottest man she has ever seen. Do have a sense of humor about this and have fun.
