Fresnel lens with collimating lens set-up

Hi. Boatingman here. When I joined Instrucables several years ago, there was a post showing a fresnel lens salvaged from an old TV, then set up with the mirror from the same TV, and then set up with a set of collimating lenses. Now, of course, this didn't make an actual laser, but it did extend the useful range of the focal point and, thanks to the mounting system shown, could actually be aimed. I can't locate this "Instructable", so if anyone out there does have it (or if you have done something similar), could you please let me know. Thank you.    Ed
