And finally, some screen shots- not very good photos (still figuring out my camera) The screen is a piece of cardboard spraypainted w/ Rustolium Metalic Aluminum- The lines in the projection are on the cardboard- I'm making a screen of either blackout cloth or black and white poly- more screen shots to come.
As of this posting my bulb has burned out, I didn't touch it and I added the dimmer and heat sink, but still only got about 6 movies watched- anyone have any thoughts?
