Hallowe'en 2008

 
 

This year's theme was The Wizard of Oz.  I hacked up a rear projection TV that I got off of Craigslist to be the Great and Powerful Oz.  The original intent was to use the then working TV to present the image from a camera.  Unfortunately, the moment I started tweaking the gain controls to get a bright and colorful image the high voltage supply popped!

No worries though as I was able to strip out the interior entirely and utilize a presentation projector I borrowed from work. 

. . .

 
In addition to the projector I had a couple of brass lanterns mounted to the sides of the TV and a mic and amplifier connect to the speakers.  I also fabricated some simple propane torches for the top with bit of old bed frame and black iron pipe.  These were connected to a regulator and valve to allow me to make them flair up on command.
 
Shown here is just the test, I had two complete circuits, one high pressure and one low pressure.
 
 
Fire and children don't mix well so I put the whole rig up on my flatbed trailer to keep the flames well out of reach of, well, anything.
 
 
And of course I needed a curtain to hide behind.
 
 
The Scarecrow pointed the way and had a CD player and speakers inside playing If I Only Had a Brain on a loop.
 
 
 
The yellow brick road was drawn on the driveway with chalk.

Everything is better with fire!
 
This was just a test video but I ran out of time and never re-shot it. I was far greater and more terrible for the kiddos!
 
 
The Witch's lair blocked our usual doorway to direct the kids to Oz and the curtain.  It is a shame we did not have a Toto to pull the curtain back on que!
