Firtst time /diy/ post So I made a smartphone projector out

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.

>>1014412
Why don't you just place the phone upside down?

>>1014412
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.
