No, specific goggles block specific wavelengths, so 532nm goggles would not block 405nm too well.

Yes, even though you won't see a reflection off of the moon, you might see a few laser beams in the sky near you.

Yeah, if you run an LPC-815 at more than 420, you could be shortening its life...

Yes, I would use a green that is 5mw or less because they are much more visible than a red of the same power.

Don't bump old threads, please. If you didn't notice, this thread is over two years old. I would probably post your question in a new thread.

Yeah, they could leak. (usually not acid but electrolyte fluid) It's happened to me more than once, although not with a laser. I still leave my batteries inside, but not for more than a few months.

Yes, measure the internal diameter of your pen and see if it is close to the diameter of the caps. (they won't be the same because of the threads)

Yes, you could reshape the heatsink while still getting pretty good heatsinking. Of course, if the laser gets hot, you should turn it off so you don't kill your diode. If you run the diode at more than 420ma, then you are most likely shortening the life of your diode, so I wouldn't run it at...

If you open up a dead computer, there should be a square heatsink (2 or 3 inches across) on a board, on a large chip that runs the entire computer. If you don't know what I'm talking about, watch this- DIY: Hack a Dead Computer into a Burning Laser! - YouTube With proper heatsinking, you could...

I really can't tell you for sure, but they sure look like they would fit. Actually, to tell the truth, I would be pretty surprised if they didn't fit.

It would probably be pretty hard to get a ball like that. Copied from Wikipedia: "Otherwise, modern uranium glass is now mainly limited to small objects like beads or marbles as scientific or decorative novelties." Oh, also, fluorescence is what makes your white clothing seem to glow blue when...

Yes, that's true, you are lucky if your laser works at all after blindly lowering the resistance. Here is a thread about pot modding: http://laserpointerforums.com/f51/pot-modding-faqs-40510.html "The vast majority of laser pointers available on the open market now are operating at or near the...

Speaking of an afterimage, look at this: Jesus Optical Illusion - Optical illusions from eyetricks.com.

Look at this item that I found on ebay: 200mW 660nm 3.0-3.7V /Laser Diode Module/Red Laser Beam | eBay It is exactly like the green laser modules, and it comes from a seller that sells lots of laser stuff, so it is probably labeled correctly. Intresting, isn't it?
