Hey, thanks for that, I kind of had an idea about that but was worried about the machine lasering everything, I didn't think it through as well as the guys here at TED: The Laser Mosquito Killer at TED 2010.mov - YouTube This device channels feedback from the flying beastie which then confirms...

Oh, so I'm not the first to think of this. Indeed I was thinking only of using it against those stationary, always seeming to be so when in an out of reach place, however I was worried about the risk of fire, or even singing to come to think of it, what's your experience of this please?

This bloody sumer we're having here, which was welcome for those from hotter climates as the heatwave gave for a good send off for the Olympics, but despite the news reports, most British detest the het, I mean heat, 32deg C, not fun, especially when it's still. So, my problem, that would be...

By the time I get round to doing it, I probably won't post on this forum. But, I'll find a way of getting this done.

Thanks but I don't want to use a Class IV laser or optics as this increases risk. I'm looking for a line and I think the Atlasnova Green Laser Pointer with Feedback will get me that. The conditions will be indoors, ground floor, but it does not matter as lighting conditions are mostly artificial...

This forums spent.

Right well lets not get into replies like that, I'm still hunting for a solution. What about other laser types like gas ones?

My application is to embed it into a counter in a shop, the counter allows staff to pass from staff area and onto the shop floor but the idea of a barrier like a piece of rope or a gate seemed too cumbersome. So I thought that a red laser beaming across the two counters (at about hit height, of...

So is there such a thing as a Class I green laser? Totally safe, yet visible in normal air? You say <5mW, but I read that visible lasers start at Class II and they're dangerous. So its Class II or nothing then? If thats the case then can I go the red route? I found one on Amazon UK that says...

Thanks, but what of the other colours? i take it they are just too powerful? With a <5mW laser what happens if you look at it for say two seconds? What about the ones used in clubs? They reflect in all directions, how are they safe? I really would like a red one you know, is there no way to get...

I want to use it in my shop, as a barrier. So people see a red line (a laser red line) and think ..o0 better not go there! See, instantly people will understand from the movies that its not a good idea to cross the beam (it might cut me in half?!), it could trigger and alarm and its red, which...

I have been researching into lasers and like the idea of a safe one, using the Class I anywhere is safe and that's what I need. But that's not it, I need a red beam, something seen with the naked eye and all I read is that people like to burn stuff. I need a red laser beam, not dot and need it...

Thinking it was just "Hollywood" at first, I've found that lasers which can be seen by the naked eye are actually real. However, I am after a Class I version, something completely safe yet visible. Oh, and in red. Nay you say, it cannot be done. This is disappointing, directed to green instead...
