I am thinking of making my own Lie Detector, Has anyone here made one, I am trying to find a wireless remote- loud / flashing Door chime / bell, maybe a buzzer sound, obviously something that sound like a bell / foghorn / buzzer. magicwalsh@gmail.com

I found an instructables on it

ww.instructables.com/id/Build-a-Lie-Detector!/

The louder and more obnoxious the buzzer you can find the better, this is a great comedy bit. I have built several throughout the years. Place everything in a large project box with flashing lights, etc.

This is my version. I use a siren, laughing horn with LED lights and my own smoke producer.

That looks great Lou, but its a little larger that I want. just a loud door chime with a strobe light and buzzer sound is what I need.i wish I could try before I buy, this one looks ok for me.http://www.1800doorbell.com/db800-lh19200-portable-wireless-7-sound-chime-flashing-strobe.htm
