SO i recently got a new projector, Panasonic AR100u, the thing is a light cannon, compared to my old ae700.
Just like the title says, I am considering trying to add a trigger input to one of these made in china electric screens that you can get almost everywhere for fairly cheap ($500+/-) I think it's going to be fairly straight forward as the input controls for these screens are 12V, so adding a trigger input is just a matter of tapping into the existing wiring, and making it look nice with a decent looking built in connector.
I currently have a 120" screen, and I'm considering getting a 150" motorized screen. But most of the low cost screens out there don't have trigger inputs. The cheapest and best electric screen with a trigger input I can find on the market is from monoprice, but the casing is black.... I guess i could paint it, but I thought I may be able to ad a trigger input to the Low cost screens offered on Ebay, maybe someone here knows how to do this, or has seen an online tutorial for how to do this?
