So that about says it all. Yeah i'm a noob, yeah I don't know much about lasers, but that's why i'm here. I'm convinced veteran members are hazing new forum members to force them leave. They want to use this place for themselves and not let the community grow. You know who you are. :thanks...

I'm under the impression a neutral density filter could cut beam power down significantly, and at a 1.5 density effectively turn a 100mw laser into a 3 mw laser. But is that ok to do? The glass absorbs the light, but I can't imagine it having an issue with up to 200mw. Also, am I right on...

Alkaline Battery Shoot Out It's nice info. since lasers take low amp's and there are multiple tests it looks to me like the best aaa for maximum average ah would Rite aid, and a extremely close second rayovac max. I was looking for my new 5mw optotronics and thought i'd share

I've been trying to find a ratio for how much power is lost each time a laser is split. I was hoping it could drop mw output on a ~ 100mw laser through a star grating in order to use at concerts. if there are 100 dots would that mean each one would be 1mw?

sorry for the long post. I need details in here so I don't put anybody in danger.:thanks: also this is going to be a bit taboo, so please try to be nice. I'm trying to find an acceptable power range that people can view the beam and dot without glasses, and still pop stuff and light...

I'm trying and failing to find out why one would break the driver parts out of flashlight hack before installing the flex drive. I just can't find it no matter how hard I search. I don't know what to look for. thanks

I watched a video of a jayrob flashlight build. the person used the host flashlight and broke off all the parts on a circuit board called a driver. I'm assuming this is just to pass voltage without any metering. Then a flexdrive was installed. is this the new new voltage regulator? and if...

Hi I just got into lasers and have done a lot of reading over the past few days. from what I gather, the cheap lasers found chinese distribution websites are rarely as strong as they say, and some can be dangerous because of extra IR. I'm trying to find out if they are even safe to use at all...
