Well I have added some stuff to my holiday lighting....
I realized that I can change the main image on the house any time I want by re-installing any figure I want - be it snow flakes - shooting star or X-mas tree on to the 3/4" emt stuck in the ground out front. Whatever I want cut into plexi ot tin roughly 1' sq will project on the house 5' sq in dual color of red and green on yellow mixed.
I also added some homemade gobo's that I was talking about.... One fixture (snow flakes) I made will project ~100' with a simple MR-16 12 degree spot through a telephoto lens from an old camera. By using the zoom I can make the image big or small.
And another super cheap gobo (Merry Christmas) by simply duct taping a 50mm SLR lens to a MR-16 bullet fixture with a colored lens and small spacer of 2" EMT. With this one image size is soley dependent on distance to projection surface. (Far big - close small)But the effect is neat!
I still have some aiming and focusing to do - but I'm pleased with the effect.
I still have another idea about animating some "snow" out there by using a disco ball mounted horizonally....
Anyone got any other neat projection ideas?
