Sorry I've been missing for awhile. I've got some cool photos to show when I get the time to scan them. I took this one the other night of my brother, and I thought you all would appreciate it. Basically, what I did was used a line generating diffraction grating on a DX 50 mW and had my brother...

I noticed that there was some talk about TECs on another thread, so I thought I might start this one in hopes of creating a resource on the topic. I personally know very little about them, but I'm sure that others here do know a great deal. Here's my TEC I got off an older computer. If anyone...

So I found this today, and I want to know what everyone thinks about it. The green ones seem like they'd be awesome, since they block 532nm and 1064 nm (so it'd be Perfect for playing with a DX 200 mW). And they seem cheaper than WL or Nova's goggles. Plus they look pretty slick too...

I've been busy working lately, so I only get to work on my lasers in the wee-hours of the morning... I got one drive, and sure enough, I screwed up the laser, at least as far as I can tell. When I first got the diodes out, I kept getting mixed up on which one was the IR and which was the Red...

I saw this on HowStuffWorks, and thought I'd share it. To some here, it might not mean much, to other's, it might be a "Wow, that's kinda cool...when can I get my silicon hybrid laser." But mostly, I thought I'd just share this knowledge. These guys sure do rattle off their chemistry words fast...

Sorry I've been MIA, I went on vacation. It was a really nice vacation, and then it got better when I got back, because the day after I got home, my DX 30 come in the mail 8-) I just thought I'd share some photos I'd been taking... I don't know how to post more than one photo per page, so I...

I don't know if this counts for "laser-show" but it seems to me like it's a good place for a discussion of these fun things should go. I built mine last night (I was so pleased, I decided to wake up my brother to show him, and he was so sleepy, he didn't even understand what was going on! I...

I don't know if any of you have seen Transformers yet. I just saw it. And I thought it was awesome. The reason I'm posting that I thought it was awesome was that there were Green lasers in the movie. I hope that's not really a spoiler or anything, just thought it was worth mentioning. If you...

Of my pictures that I've done with my laser, right now I'm liking the diffraction grating the best. I thought I'd share some of them, and maybe everyone will share their diffractoin grating pics too!

I've been lurking for a few days, I just got a cheap green pointer, and caught the bug... I've got 3 lasers in the mail from DX...and I've only had the green one a week. I'm a Photographer, and my obsession has been with light, lasers are kinda like a dream come true for me. On a different...
