Four Steps to Build an Ambilight for Projector Screen

I built an ambilight mounting behind my projector screen to sort of replicate the philips experience. This is obviously for people that do not put up their screen when not in use. I thought I would be putting the screen up way back when first building the cinema. I was even looking at electric screens, but the fact is we never put it up. In fact I will be getting screen material down the line and building my own screen frame. That’s the reason I used the LEDs all the way around the frame. The effect works well I think. It works best for TV and light viewing. I find it slightly distracting during movies.

All that’s needed include: 
5.2 meters of 5/8inch (16mm) wood. I used crap but free pallet wood.
A 5 meter smd5050 led strip with IR controller.
A roll of duck tape, sellotape, wall plugs and screws, tin foil, glue,
Some sort of thin board.
Plastic tiling edging. get it in any DIY store.

Step 1: Make the wooden frame and mounted it to the wall

The measurements of the frame are 1700mm by 860mm with 100mm LEDs at the corners. I worked this out on CAD to get the most out of 5 meters. If you don't want the LEDs running along the top then you will have much more length to work with. The edges of the frame are 130mm from the outside edge of my screen. My screen is 86inch.

Great project! I love Fringe, by the way... Unfortunately, it's over... :(

Looks great :-)

I hope no ducks were harmed when you stole their tape. Maybe use air-con "Duct" tape next time :-P

[Vengence]

It's actually called duck tape. Anyone that knows what they're doing knows that "Duct" tape is the worst thing to us on AC Ducting. It was never meant to be used on ducts. It was invented in WWII as a quick patch to ship hulls so is water resistant, and was the green color of a mallard's head, so it was called DUCK tape.
Now you know.

Oh, so sorry; we only get duct tape in our small village in the Pyrenees...No one here has much to do with American affectations.

Touche. :P

"touché"?

"touché" what? Touché de violon?

Qu'est-ce que tu veux dire?

If someone ever comes up with a way to put something in an hdmi cable that will control an led strip, for less than $20, they will be my hero. The only problem I have with these ambient light solutions is they all require control from the computer, and I watch PS3 mostly on my projector.

Why not use a Light to voltage sensor, some relays and hey presto covers at least red, blue, green. With an array, you potentially go to 2nd order colours.

Something like....

or this part number for more independant TCS3103FN

It's Fringe! (i.e. the TV show, for those unfamiliar)

You should enter this in the Hurricane Lasers Contest! http://www.instructables.com/contest/hurricanelasers/

[stringstretcher]

why would they require control from the computer? "require?" seems like a harsh word... Arduino!

I like it. How well would it work in a wider room? I actually thought the light around the wall corners was coming from the edges of the room. Very nice effect.
