Those pictures look like normal cave photos to me. Cave exploring is something I have enjoyed from time to time. Although I am not a member of any of the local "grottos" as the local spelunking groups are called. Mostly because I enjoy exploring them, and it takes away from the wonder when...

It's a link. Kenom, thanks for the wonderful help with the pictures and everything!!!!!! As for the crystals. they are a purple sapphire. they've got a slight color change, they look nice and purple under incandescent light, and in sunlight look much more of a violet-blue. Under UV or a...

Huffing, about as good of an idea as plastic flamethrowers filled with fuel and air.... I'm not sure which is more likely to kill you. I also knew someone who tried huffing butane then scotch-guard. He didn't die, however he ended up in a coma for a few weeks. They even aired the story on...

meh, It all comes down to how long you want the diode to live. I set mine to a nice conservative 380ma. I might change it however once the 12x murder experiment is complete. At least depending on the results. I also might change the setting depending on how long people much braver then...

lol live and learn. I fried my 8x diode with leaving the soldering iron on it too long. $150 down the drain. (perhaps "up in smoke" would be a better phrase). My big mistake was starting with the nice expensive diode, rather then starting small. Meh, at least I learned from the mistakes...

Rear view mirrors have 2 angles they will reflect at. One is for daytime viewing and the second for nighttime when someone's brights are on behind you. A laser beam could easily reflect off the different angled nighttime mirror... Possible. and if done, it would cause less damage. as the...

Re: Silver host. (work in progress) You have to pull the cover off the switch, then remove the switch and the battery slides out. I didn't originally plan that but due to a stupid mistake had to make it that way Basically I forgot a small but important measurement when making it. (live and...

Ok, I've gotten my 12x metered :D Thanks to kenom. It's putting out 545mw with a flexdrive at 380ma. Using a LarryDFW lens assembly. The host is a custom host.

Ok, I've measured 2 of these diodes now. One from my own drive, and one from Exerd. Both have measured at 3.73mm at the widest point. It's harder to get an accurate reading on these as the outside diameter seems to be a little out of round. Depending on where you measure it, the measurement...

I personally see the beam much better indoors in dim light with my reds then my br. my 12x blu-ray is still not as visible to me, beam wise then my ~250mw reds.

you could try simply shortcutting to the inevitable end result and simply douse yourself with the gasoline and light yourself on fire... You might actually survive for a white with a super soaker if you could pressurize it with inert gas. i.e. argon. but then when the flame gets hot enough to...

My vote is to set it to 550mw. If we push to 600, and the diode dies early, we have data that isn't particularly useful. 550mw is a conservative amount, but what good would another evil smiley face diode be? The first was probably a freak accident, but I am the paranoid type. My vote is...

LCD screens are using the properties of the liquid crystal to twist light around perpendicular polarizations. the top part of an LCD screen is polarized horizontally. Then you have the liquid crystal layer, and the bottom part is polarized vertically. Beneath that you have a mirror. light...

Re: Silver host. (work in progress) I think I will take you up on that offer. PM sent.

Re: Silver host. (work in progress) Ok, I updated the pictures in the OP now. The laser is finished, it's got a 12X blu-ray in it, with the flexdrive set at 380ma. I don't have a LPM to check the output with, and I can't use the photo setup at my work for beam shots. I might have to ask one...

Hmm, do WL green goggles stop 405nm as well as 532nm? I've glanced at their site, and didn't see any wavelength od graph for the cheaper set of green goggles, although the more expensive pair has one listed. Just make certain they are rated for 405nm as well. You only get once chance with...

yeah lol it does look nice and photoshopped. either that or it's not a straight cylinder. There could be some mirrors in, or some kind of fancy optics. *shrug* who knows. but the appearance is kind of a wtf.. 200mw with a beam diameter at aperture of 3 inches. = 7.62 centimeters. this gives...

I wouldn't personally use a laser for self defense. I always carry one on me, but adjusting the focus to be enough light to dazzle someone, without permanently blinding them, or being too weak and just pissing someone off, would be a problem. Although I've read up a bit on lazer dazzlers. I...

Interesting to know. I will have to look up some info on them :D

Something not mentioned yet that I can see is, before you spend the money on the laser parts and diodes, buy yourself a pair of laser goggles rated for 405nm FIRST. If you plan on showing it off to another person, then buy a second pair of goggles. If you plan on showing it off 2 more then one...
