    I'm *guessing* that IR is used for the same reasons that IR is used in remote controls; (a) It is cheaper (I assume). (b) It is less likely to be interfered with by visible light sources.

    Personal attack... NO, not as such. I *did* use myself as an example, simply because I am easy to use as an example, having joined relatively recently. But if I am not mistaken, the intent and the tone of the thread implies a suggestion to impose a change in *forum policy*, yes? To reduce a...

    What is wrong with people!?

    Here is what I found to be odd:

    Can lasers become banned because of these people?

    Re: Stupi Let me amplify that... IF lasers are going to be banned, it will *probably* NOT be over safety goggles! It will be due to the immature jerks who point lasers at aircraft, people, animals (except certain insects... I admit to murdering insects), cars, *law enforcement officials*...

    Can lasers become banned because of these people?

    Re: Stupi (Eudaimonium); agree. I believe that most of the regulars on the forum are safety conscious. At least to an *acceptable* degree. If one is going to operate a laser outside, and there is a *reasonable* expectation that the laser will not hit anyone's eyes, an aircraft, etc., or that...

    Your suggestion overall was not a "bad" suggestion, but it was impractical. Also I think (just my opinion) it "goes too far", even if it is well-intentioned. The U.S. Congress does this kind of thing all the time. In *my particular case*, I currently CAN NOT meet your requirements for...

    I had a PayPal account years ago and cancelled it (security concerns). I only recently established a new one just so I could buy through this forum. In fact, I was reluctant at first to get a new one... you can search my posting history (back through June or so), and find traces of that...

    Distance Competition :D

    I already posted my experiment in another thread... I can repeat the details... Using a 200mw 532nm and a 5mw 532nm. Targets were a radio tower about 675 meters away, and a watertower a little more than 1 Km away. On the watertower, the green spot from the 5mw was readily visible, but not what...

    bennet326; I'm not sure what you mean (?)... to review... The issue is whether people should be required to show a photo of their safety goggles before asking (laser-related) questions, or before buying things from sellers in the forum. The obvious intent is to promote safety; the idea is...

    I do not have a mobile phone. Just an "old-fashioned" landline. I do not need anything else, with my lifestyle.

    Can anyone recommend me a good <1mW red laser?

    (@ LaySir, re: ThinkGeek); I'd GUESS that it is less than 5mw. It is marked as <5mw. The red spot is *relatively/somewhat* weak compared to most "garden variety" red pointers that I have seen. The beam can't be seen at all unless I pass it through particulates (steam from boiling water, hot...

    (etc) ... so I should buy a camera (which I currently don't have) before I can ask for laser buying advice, or before I can purchase lasers here... ... and on a fixed income ... which makes it difficult for me to buy lasers in the first place ... ... I guess we can exclude many retirees from...

    Yes; been there, done that, all of it.

    Can anyone recommend me a good <1mW red laser?

    (you don't say where your from...) I bought this back in June... it's pretty weak (safe)... my cat plays with it when he ISN'T BEING LAZY ( <- casting a critical eye at CAT ) ThinkGeek :: Star Wars Lightsaber Laser Pointer Kinda pricy for what it is... but "cheesy and cute". Comes w/...

    I never said that they were listening to the radio. Check my first post in the thread.

    Deep down, I kind of feel as you do. Humans are the WORST thing that has happened to this planet. BUT... that is no reason to be pessimistic, or rude, or negative, or to be a criminal, or to spread dissension and discontent. We could do far worse than to help each other, and to help stray...

    Meaning of nicknames

    Thought it might refer to pirates armed with lasers instead of cutlasses. "ARRrrgg! Laser!" ( me ducking and running out the door )

    (@ xoxos) THAT'S what I'm looking for - "Electromagnetic Terrorism". You see, I basically believe in "the golden rule". To a point. If I was playing my television too loud, or my computer speakers were turned up too loud, or music too loud... and it bothered a neighbor... I would WANT that...

    5mW lasers with continuous duty cycles...

    ..... ..... Impossible to say *FOR CERTAIN* without a laser lab, all kinds of research and data, etc. But if you " ... shove a 50mw green module into a cheap host, and leave it on ... ", it will probably overheat and fail.
