Hi,
I am working on virtual halloween window decorations, like AtmosFX. I am using a projector to project on a piece of scrim on a window. Is there any way I could use a pressure or motion sensor switch to trigger the video to change to a different video. If so would I use a DVD player or computer?

Thanks

The folks that hang out on the Props Forum include some expert electronics hack guys. Sadly, I'm not one of them. Have you posted the query there? Is it the same person looking at one video... and the next person seeing a different one? Or is it different people seeing the second input video at different location? If it's the former, maybe you can just sequence one input instead of splitting between two. I'd ask those clever prop guys. :)

One person looking at one video, and triggering the second :)

This is my first post to this forum. I hang out in the Christmas forums. In my Halloween show I had three projectors, each was plugged into a raspberry pi. The raspberry pi sells for $30. Each of the three are synced together to within one frame. All three are running Linux and support any type of trigger. Photo sensors, ultrasonic, switches, etc. the software that runs it is called FPP and is free from falconcheistmas.com. It was released two years ago. I don't think we have posted here before. Sean
