I tried searching on this, but couldn't find much useful info. Has anyone considered using a fresnel lens and a 45 degree mirror to simulate a larger monitor like in Virtua Cop? You can get a fresnel lens that fits a 19" monitor for $28 at www.3dlens.com . Feel free to shoot me down if need be. |

I've thought about it... conceptually, at least. It can be done. The sitdown version of Roadblasters does it really well, it more than doubles the "size" of the viewing area. I think the biggest challenge would be lining it up focally in a standup cab. It would have to be further away than a standup could easily handle without doing something like using a mirror as you've said. |

Nice fresnels link! I'm trying to use a small lcd and build some optics for it so that it may be stretched out the size of a marquee. I will probably have to build my own anamorphic lens but I might be able to just angle a couple of fresnels or parallel lenticules. I may also employ a polarizing lens at the front. Anyway, have you been to diyaudio? There are some people there making their own DIY rear projection systems. Good info. |

That is a lot of big words! |

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. FYI, I'm guessing you meant a FRONT projector instead of rear. A diy rear projection tv is a total waste of time in my opinion. The results are sub-par at best, and you'll have more in it than you would buying a used commerical one. |
