This is beyond cool, a quick one today guys.
On eBay , I bought a green Laser Pointer (5mW) for about $6. This is the coolest (and by far the most powerful) laser diode I've experienced to date. I've always wanted to see the physical beam of a laser , even if it's very weak. During the daytime, I've already tested it with the downtown builtings and it's still very bright! Not powerful enough though to burn things (probably if I got a beaker holder and let it sit on a match or something for 20 minutes ish).
Just a quick thought for now guys. Better content to come later, Promise!
Peace out y'all!
