DIY Small Image projector PLEASE HELP!!
This site seems quite informative but still couldn't find what I am looking for, I really hope you guys can help me.
I am actually trying to achieve the exact opposite of what most people try to do with their DIY projector builds. I am trying to make a "small image" projector.
I have tried using all kinds of combinations of focal calculations but cant seem to get the result that I am looking for. I will be honest with you, I am very new to this and still acquainting myself with it.
I want to build a projector that can project an image as small as 10mm across to as large as about 50mm - 70mm across without loss of image clarity. I also want to be able to project the image from a short distance, up to maybe 300mm away. I will use a 7" LCD (1280x800) and want to be able to build this projector no larger than an A4 size sheet of paper.
is this achievable? if so, how would I go about building it? would you be able to give me any advice, ideas?
Any ideas are welcome as my head is about to explode :-(
