I'm looking to make an inexpensive remote control lie detector box.

That just loudly buzzes when I hit the remote button.

I,ve looked into remote control doorbells and remote controled lights and havn't found anything I could use yet.

Any ideas?

I'd replace the speaker on a remote doorbell for a piezo buzzer..It might do the trick.

Are you looking to wire this from scratch or are you going to use something prewired and install it a box of some sort?

The least expensive device is the original.

A washer tied to a piece or string that either goes back and forth or in a circle (same as the boy/girl detector)

Buy a cheap remote controlled toy car. Replace the motor with a buzzer. That would work.

Nathan J. Roberts has a great one on his DVD " Back 2 School" it has a flashing light and LOUD buzzer..and its not to difficult to make. Im in the process of building one myself.

Very nice picture, Jay. Now how am I supposed to get it out of my head?

It's not inexpensive, but sure looks good.

Nice idea, but the signal across the speaker is an AC waveform designed to make the ding dong sound. You probably cannot drive a buzzer with this. It would need more modifcation. You may be able to get it to drive a relay.

I think I'd go with the cheap R/C car suggested by Lou.

Just to add, while I think of it, with a doorbell, you only get one channel or output, but with a R/C car you have two channels available (actually, you can sort of get 4 outputs if you know how to turn the reverse current into a separate output. i.e forward/reverse, left/right)- This could give you the ability to setup a 'Lie' or 'Truth' scenario if you want, so that you get a buzzer for a lie and a bell for the truth.
