Step 12Add Screamer - Optional
I found a small press to scream device at a costume store. I have not been able to find an on line sources. So if any one does please add it as a comment. This screamer was a self contained item that when you squeezed it, it would let out a pre-recorded screech. I took it apart and it was obvious where the connection was made to activate it. So I removed the rubber contact and soldered 2 wires. So when the wires are touched they activate the scream. Now solder the other ends of the wires to a Normally Closed Micro Switch.
Cut the 1, 3/4" PVC Tee as shown in the picture so you end up with an L shape. Glue a flat piece of plastic to one side also as shown. This Activation Plate will be used to activate the switch. Now glue this assembly to the base of the moving portion of the PVC pipe.
Next you need a holder for the Micro Switch that can be adjusted vertically. I used a scrap piece of S shaped metal for the base and a piece of angle aluminum to hold the switch. Drill a hole in both of these pieces that will allow the threaded rod to just pass through. Glue or bolt the micro switch, as shown, to the angle aluminum. Measure and cut the threaded rod to be long enough to hold the switch up past the Activation Plate. Screw down the S bracket and install the threaded rod. Secure with nuts on each side of the S bracket as shown. Secure the Angle bracket to the top also with 2 bolts on opposite sides. Adjust the top bolts until the Micro Switch is depressed. Now when the head pops up it will set off the screamer.
Now add a fog machine such that it blows the smoke in the trash can and add a red flickering light inside the can and your are ready for the nights fun. I'll take some more pictures after it is set up with all the decorations. Videos will be posted soon as well.
