How can I make a shoebox projector with one or 2 lense that gives a perfect image?
The one I made shows the text as horizontally inverted
Should I use a mirror, if so where should I position it? Name:  20191008_125907-compressed.jpg.jpeg

Hmm a mirror angled at 45 degrees would put it the right way around but you'd have to point your projector parallel to the thing you're projecting it on which is... weird.
Not sure how to revert it just with lenses though.

I'm supposed to make an projector with which text would be readable and in correct orientation. I didn't find any cool videos on youtube that covers that aspect. I know it's hard to obtain a good projection with this setup but I'm trying to get something decent 😭😔

What's the text need to be printed on? The old school photographic slide projectors needed the slides loaded upside down and flipped left right to produce a correct image. OHPs which produced a correct image from a transparent slide which was also the right way up to the operator had 2 lenses and an angled mirror iirc.
If youre projecting a transparency the easiest thing is just to flip the transparency.
