content: I thought it would be cheaper to make a projector at first... but then I realized I needed an LCD screen and then realized a new one would be 25$ + 2-3 ship time (320x240, 4"). The lens and light source will be fairly cheap (I have a small bucket of (alleged) 13k mcd white LEDs) and at final glance, I see the end result being sub-par. a new one is/can be under 100$.Should I just get a pre-made?

content: A $100 projector wont be very good.$500 maybe, for something that's watchable.

content: Are you talking about a projector to be used instead of a stereo microscope? If you are thinking of trying to work( solder/repair) under a camera/screen system you are going to be very disapointed. You have no depth perception with a video screen. That is why stereo microscopes are used, the stereo gives you depth perception. I just posted a thread about a camera/scope system and its limitations.https://www.eevblog.com/forum/product-reviews-photos-and-discussion/my-amscope-microscope-camera-experience-microscope-mods/msg150382/#msg150382

content: If you are interested in general purpose projectors, have you seen:http://www.diyprojectorkits.com/store/?You can get a pretty good indication of what sort of components are considered minimal standard for a range of projectors from "minimal expense" to "maximum quality" from that community / blog.

content: If I had to describe a projector, it'd be "they're all smoke and mirrors".http://diyprojectorkits.com/finished-projectors-gallery/1778-diy-projector-kits-mini-z.htmlon a tad more serious note: why do I need mirrors? if I make the box extra long, I wouldn't need them, right?

content: Right. And if you look at some of the other designs (eg, H-450) you'll see that this is true. But if you have specific questions about projector design you might be better to ask on that forum?
