| Anyone considered using a fresnel lens/ mirror system? |

I indeed meant rear projection. Rear- Projection TV: All-in-one display consisting of a translucent screen with a rear projector system. ^^That could fit in an upright cab Front Projection: A system where the projector sits in front of the screen with the image getting reflected back to the audience. ^^That would not as easily fit. P.S. sorry I couldn't be of further help. |

I have always been tempted to walk up to a Star Wars cockpit with a fresnel... just to see if it works as well. Probably would not with pure vectors. |

Klov has it listed as using a curved mirror only, but I thought there was more to the image than a curve. Good thing the mirrored plexiglass I have isn't wide enough, because I'd probably be trying to figure out how to accomplish it with my copy of Starblade Alpha. --- Quote from: shardian on October 19, 2006, 08:12:37 am ---I was a vet of www.diyprojectorcompany.com before it closed its doors and sold out to lumenlab. I don't care for lumenlab, so I gave up the diy projector stuff. Yeah, diyaudio has alot of very good diy projector info, but is more of a reference now than a forum. --- End quote --- Checked out lumenlab and liked that idea a lot more than the old 13" TV/mirror/fresnel box. Are the results really as good as it seems from the vids? Shelling out $1000+ for a projector isn't something I'm comfortable with. |

I've seen some peoples setups using 17" High definition lcd's that are pretty dang impressive. The higher end/ better quality build pj's using high resolution pc monitors are very nice too. I personally opted for the smaller, cheaper projectors. Mine (although indefinitely on hold for more important matters...plus the fact I have a commercial one right now) utilizes a psone lcd. My bulb will last roughly 10,000 hours, and costs $20 to replace. Resolution isn't great, but good enough for a rec. room definitely. I have roughly $100 invested in it. There are three main benefits to a diy lcd projector 1. Long Bulb life. 2. Cheap replacement bulbs 3. New addition of small scale (17") High definition lcd panels. A commercial high def projector is still mucho bucks, so a high definition capable pj for $1000 is a deal. What scares me from the high end ones, is that is doesn't take much to create a $1000 brick. The lcd can be scratched or fried during the build...there went $200. I don't know about the rest of people, but I have a problem with throwing away $5, much less $200. |
