    Lidar

    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.

    Posting a picture of safety glasses before starting a thread

    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.
