Anyone considered using a fresnel lens/ mirror system?

Hey, my first post!  I actually did this 13 years ago.  I ordered the lens through one of those "not sold in stores" catalogs.  It was meant to turn your 19" TV into a 25".   I actually built an upright cab to house my hacked up Atari Jaguar.  Aside from a slight haze it produced it was actually pretty cool.  I used a 13" TV with the picture reversed.  Once I figured out the distance and how big I could go before loosing focus I ended up with what appeared to be a 30" screen floating about a foot or so past the back of the cab.  It's been dismantled since. Now I just chase my 2 year old son around the house with the lens in front of my face and I already have a large noggin to begin with :).  When I get time I actually plan on rebuilding the project from scratch cuz let me just say the original, although functional and got plenty of gameplay, was not pretty to look at.

Welcome to the forums!

I think when I get around to fixing my Star Wars I'm going to order up a fresnel to see how much distortion it gives the vectors.

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.

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?

Working monitors don't usually get tossed.  They just get sent to someone else in the company lower on the technical ladder.

You'd think so, but it's a regular game of Keepin' Up With The Joneses around here.  When one person gets a new setup, someone sees it and wants a new one, and so on and so forth.  They bring everything but upgrades in through Dell, who doesn't like to knock much off the price for refusing a monitor as part of the package.  So, we end up with extra monitors on top of all of the old stock that's being decommissioned.  After enough of them build up and somone nearly breaks their neck tripping over them or they decide they need extra space, they say "I need these gone.  I don't care what you do with them, just make them dissappear."  I'll run it by the IT guy most times, but I've learned he doesn't care once he's gotten his pick.  Thus far, I've acquired some 17" and 19" CRTs, some working PCs, and various other parts.  Judging by the LCDs they've got laying around and the fact that a few people are talking new workstations from time to time, I don't think it'll be much longer.
