My brother has been using my cheapie(at $120, but I'm sure I got ripped off) green laser recently, and he mentioned something about shooting it at a fly that wouldn't get off of his car window. He said he was sure the laser hurt the fly, but I'm not too sure about that.
If your brother can't behave responsibly with a laser, then for the love of god don't let him use yours!!!!!! Handing someone who behaves like that something that belongs to you and is capable of causing damage, makes you an accessory to any damage they cause. There is a lot of legal precedent for this sort of thing.
There is a moral and legal issue at stake here. If you hand someone you know is not responsible your firearm and they play around with it like it's a toy, you can be held responsible for murder should they shoot someone with it. A laser is no different except rather then dead or badly wounded, the victim will end up blind for life. You are legally responsible for what you do with your own property. You have a legal responsibility to avoid giving dangerous things to people you know will use them dangerously. A lawyer simply needs to prove that you knew your brother wasn't competent to handle it safely. If a lawyer found the posts on this site, that would be enough to convict you.
If you aren't 18 yet, then it would be your parents who could go to jail, or be sued for someone losing an eye. However ending up in the foster care system is not exactly something you want to risk. Just play it safe, and don't let your brother touch the laser until he can handle it suitably.
...Then you shouldn't be letting him play with it -- that's your responsibility. Unless you *really* got ripped off, a $120 laser is going to be well above 5mW, and therefore dangerous. If someone pointed one of my lasers at anyone's head (even the back, and especially my mother ), I would never let them get within 10 feet of it again.
Also, you're not going to win any friends around here by making sneering, sarcastic comments to senior members.
First, getting the laser away from your brother would be a good idea. A laser will kill bugs, but near a window is a prime place for issues with reflections, so everyone in the room would need goggles. You are right about flies moving quickly. I have found that the minimum for flies is my 2W IR handheld, my 4W is better. Goggles are mandatory at these power levels. The next problem is that if you miss the fly, the laser blasts a hole through the fiberglass screening. To make a long story short, a flyswatter or a shot of raid both work better and easier.
Well, I could simply be a freak of nature, but I thought that the RATIONAL response to someone being patronizing wouldn't be a positive one.
I may not be friendly, but I don't cross over into the territory of "asshole" without provocation.
With regards to my brother, we're not talking about a little kid brother or something. He's approaching his 30s, and 8 years older than me. You'd think the older one would always be the more responsible.
I also don't understand how you would approach someone a full foot taller than you who bossed over you for over half your life. I mean, do I hold a knife next to his carotid artery or something? Because the general opinion around the household is that I'm always wrong.
The geckos I'm speaking of are of the pest variety, about the size of a large cockroach. I highly doubt they can eat other roaches. I don't make a habit of torturing animals. I did that enough as a kid, and I feel like smacking myself for it when I look back on it now.
Laser safety isn't lost on me, as I did order laser glasses with my Nova. My right eye is already crippled because I played around with a red laser pointer from 10 years ago as a kid, and I kept staring at the sun. I assure you that the stupidity is behind me now.
I'm also curious as to what you might be referring to when you say that I should use the laser "for more constructive things".
I don't do any construction or hunting, and I'm afraid to point the laser at the sky because there might be a plane I couldn't see. From what I could tell, most people use their lasers for recreation or entertainment. Any potential use for a laser will NOT require more than 5mW of power, or will require much more power than what a handheld laser can produce.
