Re: FS: Laser Power Meters $150 *more available* Bump. Looks like I might receive this before the S*KY GB. :P

Does anyone know (or is there a guide) how to make your own diffraction gratings? You can get the film from rainbow symphony, but I guess my question is..can the film be layered on top of each other to create a more exciting effect? Something like the different types of matrix gratings that nova...

Re: **** True >200mW 532nm S-KY PGL-200 handheld l It IS a scam. Lava and I are spending your money in Vegas right this very second. 8-)

Re: NIR  Photo of DX True 30mw running at 4.5 I will do this when I get off work. However, mine is running off 2 e2 lithiums rather than the 4.5v tgm is running his off of.

Re: NIR  Photo of DX True 30mw running at 4.5V I have done this same thing with a webcam and you can see the dot on the wall. Its just about as colimated as the green spot. I dont get why 8/10 people say that the IR light spreads out like a flashlight as soon as it exits when you can clearly...

How would you go about doing that? Do the threads at the bottom of the batt tube separate with force?

Re: Someone picked up my 100mw red and looked into Yeah, whenever I have a high powered red on me, I keep some matches nearby. "Hey, lemme see that thing.." *lights match and hands it to them* "Oh shit, man! Put that thing away!" You needn't say a word. :P

Theoretically, how long could you run one of these things in a room temperature environment continuously? I have no experience with lab-style modules, and I recently registered at PL and saw a guy running 2 open cans mounted in blocks of aluminum for 5 weeks straight. What would you expect the...

Re: potential glasses GB? **22 interest so far!** Yeah, remove me from the list, as well. I think Im going to search around for something different. Me wearing prescription glasses makes it a little weird, too.

Re: >150mW mini red lasers for $63 Nope. Red lasers are run from a diode that emits the red light. There is no such thing in existance that does the same for green. The green hue of a pointer is made by shining the light from an IR diode through crystals to convert it to the green wavelength. If...

I dont have a 10440 in my posession (nor have I ever, so I dont really know the dimensions compaired to a AAA), but wouldnt you be able to do the same thing by placing a spacer or some type of spring in the bottom of the tube?

I purchased a DIY red pointer from a member of the forums not too long ago. It came minus a resistor, and pumped out around 260mW..for about half a day's use (maybe 7 mins of actual runtime). He then sent me the same laser with an added resistor, and its been going strong for a week or so, but...

Re: >150mW mini red lasers for $63 Let me know if you ever make something compact that can put out as many mW as the first one you sent me without the 5 min diode life. You can definitely feel the power drop from the 1st to the second. Ive managed to light matches from about 8' with the...

http://en.wikipedia.org/wiki/Dead_man's_switch Was that Swordfish that starts off with the guy in the bank holding that bomb detonator with the dead man's switch built in? If he was shot and dropped it, the place would blow up. Same concept. The plug is supposed to be attached to a lanyard on...

Re: FS: Laser Power Meters $150 *more available* Ads, huh? I wondered what that empty space was in this post. Hurray for adblock.

Re: FS: Laser Power Meters $150 *more available* Giveittome. 8-) PMed.

Re: >150mW mini red lasers for $63 What's the new project? 18650 powered RGB pointer? [smiley=lolk.gif]

Re: **** True >200mW 532nm S-KY PGL-200 handheld l The end of the week is approaching. Cmonnnnn, China! :P

Ah, merci!

Oh, trust me, I have no intention of taking my investment apart. ;D There were just a bunch of disassembly pics and discussion that I had the urge to look over while at work, today. I guess I could always check the S-KY dir on lava's page.
