|I buy these motion activated security lights from
Wal-Mart for under $10. Make sure the light has a "test" setting and the
"no time" is continuously variable.
This brand, BRINKS that sells for about $9 has the
features you need. They come in white or black. I try to use black as
they are less likely to be seen in the dark.
I also use a standard extension cord and a little
widget thingy that changes a light bulb socket into a plug. Shown in
white here on top of the box.
||Here you see the light out of the box. It comes
with the two orange wire nuts.
I cut the
socket end off the extension cord. The ribbed wire (look on the side of
the wires on the extension cord and one will be smooth and one will be
marked or ribbed. The ribbed or marked wire goes to the wide plug end.
The light will work either way, but polarity is a safety issue. The wide
plug goes to the white wire. (Wide-White) So the ribbed wire is going to

Use the wire nuts and connect the ribbed wire from
the extension cord to the white wire from the light. Connect the other

light socket. Then plug what I want to activate into the extension cord.
As an example, on my coffin sit up I plug the
sprinkler valve that activates the air pressure that makes him sit up,
the computer speakers and the audio device (I use a great little sound
chip from Cowlacious.
I use the other light fixture to place a red flood
light in. This is all placed in the bottom of the coffin with the IR
detector hanging over the edge of the coffin looking out to sense when
to activate everything. Then it makes the prop sit up, activates the
sound and throws a red light onto the face (from down at the feet) of
|TIP: Play around to get just the placement you
want of the IR detector so it will not activate the prop too soon. You
want the trick or treaters close to get the best scare. Don't let them
get close enough that they could be leaning over the coffin. They could
get hurt when the prop activates.
test setting to get the motion sensor (IR Detector) to go off when you
want. In the test setting the light will light whenever you are in the
area where the sensor can see you.
Use the variable on time adjustment to let the prop
stay on as long as it take to say what it will say or do what it will
do. Then the prop will reset.
