We had a fire nearly get out of control at a camp in West Virginia several years ago, thanks to fire extinguishers it was put out. Lesson learned, don't use gasoline in an open fire in the woods.

I have a 250mw 650nm and you can barely make out the beam in darkness.

:wtf: has happened since I was gone, the trolling is out of hand. Just read all that. Yeah, Fel, I would take the laser away. I was not even permitted to use a red bullet style pointer until I was twelve or so.

Works fine for me, maybe he resized?

If you're trying to test the diode then why are you asking us for the answers? Do the test yourself and find out.:banned: edit: You're nothing but a damn troll leave the forum alone.

Did you make sure you didn't overheat the diode while soldering?

I'm not family with this wavelength? How much would a handheld sized 578nm cost if even possible?

Nothing but a damn troll. Nobody talks like this or asks others to buy them lasers.

Certain links on their site linked me to graphic p o r n. :undecided::evil: Would not even go that site anymore.

Re: FS: Custom Host NDG700 Build Freaking good deal. These are usually at least $300 new.

You might want to reconsider that system? Even with a beam expander, that system will have to be awfully accurate to get any decent range.

Sweet idea. I'm wondering what you use a laser for underwater though. Hey Bob, the guardian is listed as waterproof just so you know.

Ahh, we pulled our air support while fighting the Viet Cong. Hope air support comes back soon. ;) :p

I got that too.

Last time I built a laser I found mains power ran it the brightest! :crackup:

I'd say go for the jetlasers or the one Podo said as long as you have goggles and really have thought about the possibility and risk of blinding yourself and others.

People are pretty stupid! I show lasers to people and some are like, "what happens if you point it at that airplane?" Glad you don't own one bro...is usually what I want to say.:o One moron I saw on here wanted to cut zip ties with a laser to break into a friends apartment...like :wtf: dude...

That's such a good picture. I've never been able to image 405nm lasers well. Thanks for the good mention Zach. :) :beer:
