Building a double sided poster light box for there Theater\Media\Game Room
Bender:
I agree that up close the resolution of a printed poster would be a good deal better, but from a few of feet away you'd never be able to tell the difference
the reason they haven't all moved to LCD's yet is simply expense, theaters can get what is essentially a light box for next to nothing probably under $50
and an LCD is gonna be a hellava lot more than that
Having said all that I love your project and can't wait to see it all lit up! :cheers:
oh and I think you'd have to really knock down the brightness and contrast on the LCD so it was a lot more subtle

Update!
I ran into some problems. The 3 sets of Nova Leds was not enough. Plus I guess I had them to closr to the fram. They were creating hot spots and not lighting much around the hotspot. I had to re-work everything. I had to mount them farther back and add 6 sets instead of 3

Maybe reflectors would help?

Also paint EVERYTHING inside white including that black tape between each light which is just exacerbating the problem

Maybe covering the tape with some reflective foil tape for sealing ductwork would be an easier route than painting tape. Or just retape with white electrical tape. I just see painting the wiring and tape as a messy disaster. :dunno
