| Post subject: | Portable Projector Screen 2 Photos |
Okay, so I built a screen to mount to my table, but it didn't work very well. It was difficult to make it sturdy enough, so I scrapped it and started over. The first screen was front projection, and the other big problem was getting the projector into a position that was protected from drunks knocking it over. I sat down and re-thought the whole idea. I decide that I would be better off with rear projection. I had an old projection TV that didn’t work. I popped the screen out and set it on the floor and projected through it, and was shocked at how good it looked. The screen has a Fresnel lense and some other layers, which increase the brightness. The image was so good, that I had to figure out how to make this work. The screen only weighs about 25lbs, so I came up with a PVC pipe knock-down frame, which mounts into the end of my table. This is a bit of a compromise from what I wanted to do, but it works so well, and the image is so good that I don’t feel too bad giving up a few of my wants. Here are some pics of the whole thing put together and running. http://www.flickr.com/photos/22794316@N03/ Let me know what you all think. |

It would have been a lot easier to just use a LCD. You are not gaining any size with that setup. But it was a cool idea. |

lyquiddye, This is not a fixed installation. This is supposed to be a portable knock-down traveling system. How much does a 40" LCD weigh? How do I protect it for travel? I have a 42" LCD in my living room, and I don't know how I would move it from job to job...it was hard enough setting it up the first time. This system breaks down. The frame fits into a speaker stand case. The LCD projector has it's own carrying case. The screen fits into a portfolio case. The heaviest item is the screen at 25 lbs. This will be used depending on the venue. If I have an open wall, I will project directly and not use this set-up. I can get the projected image as large as the wall will allow. |

I just realized that it might not be clear that the portable screen in the pictures from my above post is 40" diagonal. Maybe it looks smaller in the pics. The projector can also be used without the screen to project larger images. |
