Ok, i have a little project, which started from looking at a cheap laser with those caps...
Can I make a shape that i can shine on a wall?
Here is my theory.... (which is probably wildly wrong... but anyway)
the caps look like glass with a pattern engraved on it. So... if I got a bit of glass and laser engraved a shape on it small enough, then stuck that in front of the laser... would that do the same job? Looking at the cap, they do look like a bit of glass with a shape engraved on....
I have googled it and every site either shows a line grating or goes into the science... I just want to see if it works!
I understand it wont (if it worked) produce the cleanest image, like the cheap caps, but seeing as i have a friend with a laser engraver, and I have a laser here... would it work?
