Had a friend at work come out to my car to see my 1.9W big boy.....
Its was pretty cool to shoot about 8 feet away at my window of my car "was below freezing outside" at a dead leaf on a tree moving in the wind and I was still able to make it smoke and burn a big hole in it!....
Was quite the show off toy!
He now wants to buy one as soon as he has the coins!
Everyone mentions DTR's builds, but don't forget his diodes!
I bought 405nm 12x and 445nm M140 diodes from DTR. Both were expertly packed and shipped to me quickly. I haven't used the 405 yet, but I replaced the dead 405nm diode in my wife's pocket-mini with the 445. The lead wires made soldering super easy and within a few minutes I had ~340mW of blue photons.
Combine that with his low prices and I'll be coming back for more. Looking to build a 635nm laser for myself for Christmas! :san:
