Opaque style LCD projector

[Mephij]

I am wondering if it is possible to make an LCD projector using a small LCD screen in something similar to an opaque projector. My isea is to have the LCD on the bottom of my "Box" facing a miror above it at a 45 degree angle to it. The mirror faces the lense which projects it onto a screen. the extra light needed for the projection is provided by 2 light bulbs inside the box. would this work? would I get a lot of glare? would the image be bright enough?

Thanks,
Mephij

All you need is an LCD that uses a reflective screen.

If you are satisfied with the brightness of ordinary lightbulbs, try using household flourescents. They produce little to no heat, and require less power. Plain incandescents can damage a panel with heat.

i agree with the remark on the reflectiveness

allthough other people on this forum said ' IT AIN'T GONNA WOAAARK' .

i actually tried it in the craftstore and i saw a pic allthough the large fluorescent lamps of teh store were on.

i am trying to get a professional opaque projector, i have seen them on the net, and some guy i know who is a painter has one as well but i haven't been able to get a hold of him, i amreally wnating to ry this out as well!!!

i think that one fluorescent household bulb will not be enough, the socket is too small for a mogull and all teh others are only about 40 watts maximum i think. you could see to it that you change the socket into a mogul one but i wodner if the space inside is wide enough!

this is the Rolls royve under the opaque projectors

but if you want to go a bit cheaper
the go to google and search for : gagne trace-master


beware DO not buy this for more than US$200.00 otherwise they are ripping you off!!!!!!!!


the projectors that are listed on the dickblick website are the best and surprisingly, allthough the lenses inside are considered extremely good, the whole thing is not that expensive.
and don't worry about the temp most off them have more than sufficient cooling as they need to project film strips and that in itself does not really like a high temp.
however i would ALWAYS go with 2 extra ENERMAX fans (the 5 inch ones- it won't harm anything!!!!!

where did you find an lcd that uses the reflective method?

i think you will remain with one problem though....

the football score will be from right to left ...........

but i guess you guys like soccer more !!!!!!




soccer is for suckers!

football is WAR!!!!!!!!!

Why would the lcd have to be reflective? my mother's a muralist and she puts things into opaque projectors that aren't reflective. (drawings, etc.). and is there a way to reverse the mirror image effect?

If you flip the panel over that should fix the mirroring problem. The reason it doesn't work is the panels top is reflected and not the image. Basically you just have a big enlargment of what your panel looks like. But if you have a good light source you could stick it underneath the panel and use it that way.

[uvodee]

explain why extra light needs to be under the panel ????

and flipping over the screen ....with the backlight still in it will not do the trick of reversing the image, will it?
