Hello,
they recommend that distances but it don't mean you have to use that exact distances... you should try by your self to see what is better in your case...
about the fresnel with 200x200 you obvious can cut it to the size of your lcd, just try to center it while cutting. i have my fresnels splitted and at 1cm of the lcd.

my psone board is on the top of the lcd. theres no problem because the only important light is the one that touch the lcd so there is no problem.

in this picture you can have an idea..

Thank you for your reply ! By the way, you used splitted fressnels in what distancances each other ? Fressnel + LCD + Fressnel, no ?

And about splitting the Fressnel, if I have an OHP Fressnel to split, but the fressnel is made of many circles (when you look at it, it's like it have circles inside... so, can I split it just in half (Because this is gona loose the circles I think, it's like cutting the circles from side to side, as it's diameter, is that fine ??? Or should I remove a portion from the middle with the size I need ?

Thanks a lot, I'm desperate to build this....

you HAVE TO remove a portion from the middle with the size I need ? The smallest circle has to be centered with the center of the lcd..
the distance that i have between the fresnels and the lcd is 1cm.

I'm thinking in sell my projector.
It was very fun to build, a challege to my self but i'm thinking in give it a new home. If anyone is interested in buy my projector let me know. i spent between 270 and 300€ on it but i'll sell it for 250€ (unless anyone wants to give me more money

)
I have checked and shipping inside europe is about 35€ but i have to confirm that...
This will also be great as base for someone that wants to build his own projector.
So if anyone is interested just msg me.
Thanks
