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. --- End quote --- Given the way old PC equipment basically gets tossed out as people at work upgrade their workstations, I'm hoping that I inherit some LCDs in the near future. Out of curiosity, have you done some sort of test to see what kind of picture you'll get out of the PS1 screen? How large do you plan on blowing it up? --- End quote --- Yeah, I have. I made a test setup long ago to see the image. I popped in a vhs copy of star wars, and I was very pleased, even with the lower quality bulb and optics I tested with. You can go up to 60" with a psone. It is equivalent in image quality to an older style rear projection tv. I guess I'll have to post something here about it when I do get it done...that is if I EVER get finished with my bathroom project... |

They just get sent to someone else in the company lower on the technical ladder. --- End quote --- Tell that to the guys at the SlaveNation Army thrift store. The one here actually pays somebody to haul away the pile of them they build up every so often. As everybody goes LCD, there's a huge surplus of used CRTs. |

I was talking about corporate culture/IS practices. Not Salvation Army thrift stores. |

I wonder whether anyone sells fresnel lenses that only magnify in the horizontal plane. Could be useful for building a Darius machine using only a single monitor. |
| ChadTower:
I'm having trouble visualizing what you mean. They magnify based on the point of view of the viewer... |
