This is a video of a 532nm laser's dot on a white phone in which I place a red filter between the cam and the green dot. The red filter makes the green dot appear red. My question is: What is the source of the red laser light? https://youtu.be/LoOnOmp9J8c

Video of a red spiro I threw together in about 20 minutes.No planning involved just a couple of DC motors salvaged from cd-roms.Each wired with it's own (inadequate...way too touchy) pot with some diy mirrors made from a cd (speed control only with no reversing).I don't think it turned out too...

I stuck a piece of electrical tape on the inside bottom of a cup and covered it with about 3/4 of an inch of water and focused my new style red on it.To my suprise I heard a slow sizzling sound then I looked close and saw that gold colored bubbles would form where I focused...pretty damn cool.

I recently received a new style red from O-like but I don't have access to a LPM to check it's output but was wondering if anyone could estimate the output by how fast it burns thru a jewel case.All the vids I've seen of Dildas and the new style reds doing this have the lasers burning thru...

Hey guys...I'm new to the forum and I was thinking this "phenomena" I observed a few years ago using a 5mW 650nm pointer would be great as the subject of my first post,so here it goes.I was playing around with the pointer one night inside with all lights off except for a "tube style" black...
