    Is my lense dirty or scratched?

    Are you in the U.S. Or some other country? I myself have never purchased from Laserbtb but many here do all the time and they get their lasers without a problem. Most companies ship lasers labeled as flashlight or optical parts and with a low declared value. When you order from China or some...

    Is my lense dirty or scratched?

    Well then I would recommend you just just forget it and buy a new one. Maybe someone more familiar with the 303 will comment here, but that is a disposable laser, not really one you fix. You can buy them online from less than $10 to $20. Alan

    Is my lense dirty or scratched?

    It is DPSS if it's 532nm no doubt about that, but that has nothing to do with if the lens is replaceable or not, I was just pointing out that they break easy, like if you drop it or something. Is the lens in there removable and does it look like one of these...

    Is my lense dirty or scratched?

    It's too hard to tell from the photos but a 100mW 532nm would usually be a very cheaply made Chinese laser and would almost always have an acrylic lens and not a glass lens. You can clean a glass lens but should never attempt to clean an acrylic lens, many low cost lasers especially low power...

    Avatars being cut off

    When c0ld introduced the new DarkShadows responsive style a few days ago some people got automatically changed to it, maybe it happened to quite a few, just check that drop down menu at the bottom left of your screen and see if you are using DarkShadows V5 or the responsive. Alan

    Avatars being cut off

    It should always be ok up to 200 x 200 pixels, look in the bottom left drop down menu and see if you are you using the DarkShadows V5 style? If not then that could be the problem, otherwise I don't know. Alan

    About a laser unboxing details.

    What do you mean after the lens? If you unscrew and remove the lens, most lasers have a spring behind the lens to keep it tight so it's not loose, you want to keep this. If you are talking about a spring on the battery contact board then this is ok too, if it uses only one battery it is good...

    Jet Laser Beam Expander Adapter/M9x0.5

    ^ I second that. :gj: Your laser has a sticker that says 18000 MW :eek: I think that is a misprint, if not then don't point that thing in the sky, you might accidentally blow up a sattelite or something. :crackup: Alan

    KY laser laws?

    100% safe?:crackup: there is also Bacardi 151 also 151 proof, it has a warning label danger flammable keep away from fire or flame. Remember that James Bond movie where that guy used some bottles of 151 as Molotov cocktails to start a fire, it will really burn like that. The movie was "A View to...

    Future laser predictions

    If someone must have a yellow laser one more option that is available is a 594nm HeNe laser, but they are low power and again are so expensive that I couldn't see ever buying one. Alan

    KY laser laws?

    Are you sure it's just for two years? Don't get stuck there unable to move back. And don't buy any of that illegal Moonshine/White lightning, it's not FDA approved. :crackup: Alan

    What are the best science fiction movies?

    Yes I thought I remembered it from Escape From New York but I had to do some searching to be sure, have seen the movie at least 4 or 5 times but not too recently. This reminds me, there are at least a couple of other movies with Donald Pleasence that belong in this thread. He was one of the...

    have you got a family member to buy some thing for you

    Yes same thing here, now on my birthday or Christmas I have to buy myself something, nothing from anyone else except that my brother in NYC will send something once every 2 years or so. This is actually generous of him because I never send him anything, but he knows I have no money. We do talk...

    Diode pin connector

    Are you talking about something like this? 3 pin long wire mount for laser diodes 20" length, AixiZ of course you can test your diodes this way. If the diode isn't pressed in a module and heat sinked, then keep the test real short. Alan

    Switzerland laserpointer ban

    I couldn't agree more, this disgusts me to no end. I have heard that things are better run in Switzerland than here but I don't know if that's true having never been there. The U.S. Being the third largest country after China and India has a high percentage of the worlds "worthless bastards"...

    Any future developments won't surprise me at all anymore, no matter how impressive they may be. Given enough time the sky is the limit. Alan

    Image size in your posts.

    This really fucking pisses me off! This is way beyond what should be tolerated here! People should be temporarily banned for this behavior! Alan

    What are the best science fiction movies?

    The original was a great movie, the same can be said for "The Day The Earth Stood Still", it's unfortunate that they keep remaking movies instead of something original. You are talking about "Escape From New York" another movie worthy of this thread. I lived in New York for 3 years and I can...
