Hey all, after reading several reviews and comments from several people that bought the power rock lasers from O-Like I decided to make a video tutorial that details how to set the focus on it to infinity at the start so that you don't have to fiddle with it to get it right. I shot it with my...

I got a laser in the mail today and after popping a fresh cr-123 batt in it it started doing this. Can anyone shed some light on it? Thanks. http://www.youtube.com/watch?v=Mv2KxbhkPdA&feature=youtube_gdata_player

Oksy so I have ordered a bunch of rechargable 16340 and 18650 batteries but I understand that they are not protected cells. I want to make sure that I am using them safely and not running them too far down. Can anyone tell me how to judge when they need to be recharged? My flashlight will...

After learning a lesson and getting a crappy laser from eBay I have read a couple reviews and am planning to purchase the Power Rock 50mw greenie from O-Like. I'm hoping (especially with the reviews) to be by pleased with it. Can anyone offer any further insight or cons on it.

Ok so I have one of swims super over spec greenies and a torch that I got on eBay. I like the torch better for the form factor and because it is at least 20mW stronger that he pen but the divergence is terrible and for that I much prefer the pen. My question is this: Can I transplant the...

I am noticing that carrying your laser results in dust and lint inside the aperture and it is relatively difficult to actually get it clean. Therefore I was wondering if I purchased something like this and glued it inside the host window if it would be an effective barrier? Glass IR Filter Lens...

So I got a new torch style greenie and it's incredibly bright but despite how much I like it the beam gets far bigger than I like the farther away it gets. I would say that at about 50 feet it's about the size of a baseball. I would like it to be between 1/2 and 1 inch at that distance and not...

I have been looking for something a little more robust than just a pen style laser but and still on a pretty tight budget. I found this on ebay and am wondering if it would be okay to go with or if I will just be disappointed. Thanks for any input 532nm Green Laser Pointer (Torch Style) | eBay

I know the only way to get an exact mW is with an LPM or specific tools but my laser will cut holes and lines in one of those little black portion cups you can get at any salad bar for dressing like this: Can anyone give me a ballpark of mW by this?

I bought one of swims Super Overspec greenies and am nothing but pleased with it. However, the question I have is because I want it to last as long as possible I want to make sure that I am not risking anything with my power method. I bought some 1000 mah Duracell AAAs and have been using those...

found this on eBay and was wondering if it was worthwhile or crap? 300mw 445nm Blue Laser Diode/lens heatsink soldered wire | eBay thanks

Hey all, My name is Kris. I'm kicking around out here in Portland OR and I have loved lasers since I got my first red pointer back in like 2000. I got a taste a couple years ago for the greenies when I was using a buddies AR and it had one mounted. it was beautiful especially when we were...

What should the duty cycle be for my 50mW 405? I love my greenie but this one is quickly becoming my favorite and find myself playing with it all the time. I certainly don't want to burn the diode out due to overuse. Its just a 5.00 ebay pen. Thanks

I apologize if this is in print somewhere I browsed for a few pages but was not able to find anything that really answered. I saw in the 445 section that they will always produce a oval or line and not a circular dot. Is this the case with a 405 as well? I notice that my 50mW throws an oblong...

I bought one of the eBay 5mW greenies just to play with and have observed a behavior that I wonder about. First off I havent ruled out batteries yet so that is a possibility. When you press the button it comes on amazingly bright and is ever so slightly visible in a well lit room but then...

I picked up an (advertised) 5mW pen style pointer on eBay and was surprised when I read the holographic sticker that says that the output is <50mW. do you think that it is 50mW? I can see the beam very very faintly sometimes in a lit room, pretty easily in a dark room, and like you couldn't...

So as stated in another thread I foolishly tried to pot mod a 5mw green pointer pen and broke it. I decided that for educational purposes I would tear it down and see what makes it tick. The question I have is, now that I have removed all focusing lenses does it still present a danger to...

I bought one of the cheap-o variety 5mw green lasers on ebay and stupidly tried to pot mod the thing. Needless to say it didnt work but I managed to trash the front end of the internal assembly and break the lens. Is there any way to install a new lens or repair it or should I just pitch it and...
