    Well there is different types of quality as in most cases. I managed to get hold of a type of lense with much more "detail" than the normal type of fresnel lense.
    Its a funny thing you mentioned that because I was thinking about that yesterday . Because there is a slight vissible blur at the moment and by moving the front Fresnel to the lampside I will get a more detailed image, butthen I lose the keystone ability :( . How big this differense is, is yet to be seen...results will be in the next and hopefully last update.

    http://www.lumenlab.com/forums/index.php is probably the best single source for information, tools, and parts. You'd think I work for them, but I don't just a long time follower of the forums, trying to work up my nerve to just do it.. :D

    Sorry for the HUGE thread revival but after seeing your latest mod I just had to take a look at your projector and boy was it worth it. This is one very impressive piece of work, very very nice. You also helped me out with a problem I was having, with bending alu to make round corners, I always knew I needed a round surface but never worked out how to measure it up lol. This thread was an absolute joy to read.

    O boy, yeah that was some thread revival but it's verry nice to hear you liked it. I hope you'll like the current project just as much. As for the projector it has been replaced by a commercial one with much greater image and brightness, but non the less it was a fun project and I learned a lot building it.

    I'm probably 10 yrs late to experiment on stuff. But this thread had me gobsmacked!! It even got me to register on this forum and try out something like this as a weekend exercise. Enough of riding about, it's time to make something for my Nephew.

    What's the focal length calculation when using a first surface mirror in the "L" configuration?

    If the fresnel focal is 180mm, the total length of both sides in " L " has to be 180mm? Or does a mirror at 45deg do funny things to the light?
