Salvaging the Fresnel Lens from a Rear Projection TV

video Salvaging the Fresnel Lens from a Rear Projection TV

I was thinking of DrSimons awesome instructable the other day when i spotted a discarded TV on the road side.
Since it was garbage day, and my wife stated in no uncertain terms that it had to go "that day", I decided to make a quick video on how to get the screen out. I also salvaged a nice first surface mirror form the cabinet for a never to be made future laser instructable.

So enjoy this brief video of me looking disheveled and fat as I rush to disassemble the TV before the garbage truck comes.

Thanks for the video! I just picked up a 62" DLP TV for free on craigslist last night for this reason and my power drill just finished charging! Time to get myself some quality free parts for my tesla turbine ORC project ;)

If you all want to know what I'm up to check it out at teslapower.wordpress.com

TUA, with that front surface mirror you can make a 3D mirror array for photograph.

Our community has an electronic drop off where I usually use a pry bar or the lug nut wrench from my trunk to recover fresnel lenses. It´s quick and dirty, but the plastic housing usually gives way pretty quick.

I really want to find one of these. I had a chance to get a broken rear projection tv a while ago but couldn't find the time to pick it up. Frustrating!
