Firtst time /diy/ post
So I made a smartphone projector out of a shoebox and a convex lens. I bet you all know that the image would flip, even if I prevented the video from rotating upright.
Is there an app that would allow me to play flipped videos or images? Or should I redo my box with mirrors?

VLC could do it on a computer, the feature or interface might have been trimmed out of the android version, but you could probably get it back with the command line and then making a customer launch/shortcut/something for convenience.
Locking the screen rotation in the Android still rotates a landscape video?

In pretty much every app, yeah. Unless I download it and use VLC

That way, it's still reversed horizontally. I'm trying to find a mirror that would flush in my box, but I gotta keep digging.

It has mirroring too.
Lay the phone flat on its back, put mirror above at a 45 degree angle, like a periscope. Screen wont auto rotate on its back. Problem solved?

or, why dont you use a second lens? without to much amplification, just to do the fliping

Have you tried focusing multiple lenses?

>convex lens
I hope for your sake that you used an achromatic lens and not just a simple single element. Otherwise you're going to spend all this time getting the orientation correct, then be disappointed with the picture quality.

Why don't you just place the phone upside down?

Did you test it already? Isn't this dim as fuck?

It's not that bad.
Not for the range that these thing work at anyways.
