Home Theater, Tribute To A Friend

The Greg Williams Theater

Ever since purchasing this house, [Ed] Always wanted a to turn his living room into a home theater, but not just any old projector and a white wall would do. He wanted the whole experience. [Ed] Started with a slightly damaged 12′ wide 4:3 roll up projector screen, he removed the damaged bottom portion and built a static frame to support the now 16:9 screen. Before he could mount the screen, he needed to drywall over a window that was inconveniently located. With the screen now in place, [Ed] framed out the elevated seating platform and steps with some 2×12 topped off with plywood. Next, the carpet that was sitting directly below the platform and steps was removed and then secured on top. Down firing LED fixtures were installed in the steps, to give them that movie theater look and feel. To provide the image, a refurbished HD projector acquired from the Bay of Electronics, was installed in the loft above the living room.

With the theater functional, [Ed] turned his attention to theater decorations. Dimmable ambiance lighting fixtures, using laser cut acrylic and CNC routed starboard (a marine-grade polymer), were made to resemble a film strip. Next a coffee table was crafted out of an equipment road case filled with movie props. Studio logos were painted on the sides with the use of laser cut stencils, and with a glass top, gives the illusion it came off the set of a hollywood movie. The addition of a rebuilt movie poster marquee, movie posters, candy stand, pop corn machine, and with the existing soda fountain and the arcade in the loft, the home theater was almost complete.

In a fitting tribute, [Ed] designed and built a marquee sign to dedicate and name the theater after his cousin Greg, one of his closest friends and avid movie watcher, who had sadly passed away. Video overview of all the hard work after the break.

Fail of the Week: Projector LED Retrofit

fotw-projector-repair

That’s a deal for a project, how hard could it be to fix it up?

If you’re a real hacker we’d wager you’ve fallen for this type of thought process before. [Luft] bought this used Sharp XR-10X-L projector about a year back and planned to retrofit it with an LED bulb. He gathered all the parts and got to work, successfully testing and installing the modifications. But as luck would have it, the project is stuck in some type of boot loop.

This fail is certainly not for lack of preparation. The first post documenting his adventure shows that the hack has been done before, he acquired the service manual for this particular hardware, and he did his homework when ordering the parts. Success requires circumventing some sensors which ensure the case and internals are in place, and making sure the electronic status of the ballast is reported correctly event though it’s not needed for the LED source. Power-on gets as far as illuminating all the indicator lights in green as it should, but is then followed closely by a reboot sequence.

He tried watching the serial port to see if he can get any status info there but no dice. In keeping with the nature of this column, let’s see if we can provide any constructive troubleshooting advice in the comments.

Hackaday Logo Projector from a single LED

LED-low

Here’s another Trinket Contest entry that was interesting enough for its own feature. [Adam] made his own Hackaday version of the Bat signal. It’s not nearly as big, but the concept is the same. Using this single modified LED he’s able to project a 12″ image that seems quite well-defined (more pictures below).

The LED is one he pulled from an old flashlight. After sanding the dome flat he made a jig which positioned it inside of his laser cutter. From there he etched the 0.1″ logo and filled the negative space with some ink. The remaining surface was polished to help the light shine through, then positioned in front of a jeweler’s loupe to magnify the image.

There’s just a couple of hours left before the Trinket Contest draws to a close. Get your entry in for a chance to win!

A facelift for the view out your livingroom window

livingroom-view-facelift

[Ken Kawamoto] turned the rather bland view from his livingroom into that of some high-priced real estate. It only works at night, which is going to seem odd since the image above shows a daytime scene. But it’s still a pretty sweet concept.

The video below shows the actual view from his window. We don’t think it’s all that bad (we once lived in a ground-level apartment looking out on a parking lot… yuck!). But the view of the Abbey of St. Étienne in Caen, France seen above is much better. He simply put a projector on his balcony and closed the light-colored blinds. So far he has to bring it in after each use, but we see this as more of a thing to use only when entertaining anyway.

We’ve seen a few other attempts over the years at hacking your view. Here’s one that adds fake windows using LCD screens. The thing that makes that one work is the ability of the system to track the viewer and change the perspective accordingly.

AquaTop: a gaming touch display that looks like demon possessed water

AquaTop_touch_displayAre you ready to make a utility sink sized pool of water the location of your next living room game console? This demonstration is appealing, but maybe not ready for widespread adoption. AquaTop is an interactive display that combines water, a projector, and a depth camera.

The water has bath salts added to it which turn it a milky white. This does double duty, making it a reasonably reflective surface for the projector, and hiding your hands when below the surface. The video below shows several different games being played. But the most compelling demonstration involves individual finger tracking when your digits break the surface of the water (show on the right above).

There is also a novel feedback system. The researchers hacked some speakers so they could be submerged in the tank, adding a large speaker with LEDs on it in the same manner. When fed a 50 Hz signal they make the surface of the pool dance.

R2D2 cake plays Leia’s distress message

R2

As all 6-year-olds should, [Marc]‘s son is a huge fan of Star Wars. For his birthday party, he wanted a Star Wars themed cake, and making one in the shape of R2D2 seemed to be right up [Marc]‘s alley. Of course any clone of everyone’s favorite R2 unit should also display Leia’s distress message to Ben Kenobi, and [Marc] figured out a way to do just that.

Because of R2’s strange and decidedly non-cake shape, [Marc] first constructed a stand out of wood, cardboard, and a PVC pipe to hold the cake into place. The cylindrical droid body is of course made of cake and frosting, with R2’s dome made out of fondant.

The PVC pipe running up the center of the droid provided [Marc] with the ability to run a power and video connector up R2’s spine. These are connected to a small projector receiving video from a netbook placed out of the way.

You can check out a video of the R2 cake playing Leia’s holographic distress message below. At the end of the video, there’s a 6-year-old birthday party guest saying, “what is that?” It might be time to dig out the VHS player and the non-remastered trilogy, [Marc].

3W handheld laser raises hope for a real Lightsaber someday

3W-handheld-laser

That banner image may seem a little bit theatric, but it’s a good representation of what this 3W handheld laser can really do. Turn the thing on in a slightly smoky room and it looks exactly like a thin beam Lightsaber.

What kind of tricks would you expect this thing to perform? Perhaps it’ll pop some black balloons? Prepare to be shocked because it’s orders of magnitude more powerful than that. The video below shows it burning and igniting a collection of items almost instantly. [Styropyro] tested his creation by igniting paper, cardboard, flash paper, flash powder, burning through a stick of wood, and igniting an undisclosed substance at the end of the video. But one of our favorites is when he drives a solar powered toy car with the intense beam.

He pulled the diode from a DLP projector, and drives it with a pair of 18650 Lithium Ion batteries which are commonly found in laptops. He made the enclosure himself. It looks great but we can’t help but wonder if the components would fit in a painstakingly made replica.
