Giant Skull
Got the Big Lots Giant skull for $30 and decided to redo the eyes.
You can see this skull is 5x larger than normal relative to the door frame behind it.
Used Tap Plastic Hemispheres for the eyes, glued in with hot glue on the edges
I used powered speakers and a 64MB MP3 player to drive the audio. I'll probably have a 3min blank track, and then set it to repeat through the 2 tracks.
Thanks to Propmaster http://www.halloweenpropmaster.com/ for the audio track he recorded. Awesome!!
Ran a 2 prong extension cord through a chain and a small hole in the top of the skull. Cut the cord to get it through the hole, tied a knot to hold the skull and then resoldered the extension cord back together.
Plugged the speaker and the power supply for the Hauntmaster LEDs into the extension cord. Could in theory have the master extension cord go to a motion sensor, but probably not necessary
