Attached is a pic of a couple circuits I put together.

The microphone for the circuit on the left, will be put inside a Doll's ear, the VOX circuit will then power the servo, moving the Doll's arm,(when something is said into the doll's ear). Hopefully a "Ghost" might find this interactive doll amusing.


The circuit on the right generates a Electromagnetic field, that the K2 can see. The Pulse Width Modulation controller sends a 2.634 KHz pulsed DC to the Solenoid, the field is > 20 milliGauss at 3", from there it falls off rapidly. I thought the Electromagnetic Field Generator may be useful as a portable unit for testing other equipment.

More Circuits and "Ghost Toys" to be built,(EMF,IR,EVP sensitive autonomous/ Radio Controlled Vehicle next, Vehicle will automatically follow EMF,IR, or EVP input. Now all I need is the Ghost's :)

WOW, having trouble to get the pic to display, here is the link code:

I love the idea...I've thought about doing something similar to a teddy bear to use at one location. Let us know how this works for you.
