Help me add a trigger input to a cheap electric projection screen

post #1 of 2
Thread Starter 
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?

Okay, I'll bite....what's a trigger input? Are you talking about being able to activate the screen remotely by applying some kind of electrical trigger, or maybe using some type of relay variant to energize the up/down mechanism? Or is there an IR capability that you want to trigger from some other device?

I'm not sure I have a solution for you, but if you can elaborate a bit about what you're trying to achieve (like how it works now and what functionality you're looking to add), someone may be able to help out.
