Re: help!!!!

Well for the most part laws are fairly lax and are logical. Don't shine them at people, anything living, vehicles, planes, and government buildings. You always have to be weary of reflections as well and how the beam travels. At your budget though you would be looking more at something that can pop balloons not burn without optical aid. You can try building your own laser or finding someone on here that will build one for you at that price however. Your best bets would be here: http://www.dealextreme.com/products.dx/category.911 and here: http://www.novalasers.com/NOVAstore/pc/viewPrd.asp?idcategory=3&idproduct=83

Re: help!!!!

Cheapest way to go is to build your own and learn from the experience on this site and BE SAFE. If you're 13, you might be mature and able to handle stuff like these, but your friends might not be as mature as you and people can get hurt.

Learn a lot first - it's more fun when you really know what you're doing and why. Best of all, learning is free!

When you really know what you're doing and can figure out most stuff for yourself, you can find places here where you (or your parents, more accurately, since you'll need to order with a CCard) can order the parts you need, and you can probably have a very nice little device for under $75.00, that you built yourself.

Just remember that these ARE powerful "toys" and you can permanently hurt yourself or others if you don't know exactly what you're doing. That said, there's a lot of other people on this website that are your age building projects with lasers that amaze and impress me every day.

As for laws - if you keep the thing in your house all the time, you'll be safer. Even where there aren't specific laws about it, people can get nervous, and if the wrong person gets nervous about something they've seen you with, they can make as much trouble AS IF there was a law, so pretend they're illegal and you'll be safer! :)

Welcome to the board. There's a lot of info here, and a lot of wisdom in the members, and most are willing to share - but not spoonfeed you. Learn & have fun!

Re: help!!!!

hey, welcome to lpf, where in nc are you? i live in nc also and like rhith said most laws are pretty much common sense.
well enjoy your lasers, but for cheap lasers go to dealextreme.com but for quality and customer sevice go to novalasers.com dont get me wrong dx has good quality also but from what ive heard their lasers arent up to spec, but some people have gotten fully spec'ed lasers

If yu use a secondary convex lens (magnifying lens), 70 to 100 mW can I believe, if you blacken the match with a sharpie first.

150 - 200+ will do the job without any sharpie marking.

The homebrew I just made with a diode I bought from one of our own here lights matches in half a second - but better still, it cuts through hard plastic (black), white paper, thin wood... and it's tiny!

You certainly don't need that much power! With my 115mW CNI Pen I can easily light matches without a lens fairly quick and my 30-40mW can light matches quickly with a lens. ;D

magnifying lens= relatively nice sized convex optical magnification lens, spectacle style

As for DX, I hear it is better to stay with the 30mW and below, above that it's a gamble.
NOVAlasers guarantee customs will NOT take your laser or they will send you another one.
The 5mW max power limit doesn't really mean anything. It just says you aren't allowed to import a laser above 5mW. But as long as you are safe with it and don't try blasting police helicopters you will be fine. And what power/wavelength is your laser in the picture?

finaly a replie!!! and i dont real know the power/wavelength of it just that its a IIIb laser and that its fda approved so i assume its under 5mw?and to say again my main pirpose for the laser will be to do stuff like burn matchs and ant[as soon as we get some rain in NC]and to maby light a candle once in a while or just to impress my parents and just a thought how many mw would u need to cut through a tin can?

Hmmm... if it is class 3B it would be above 5mW. Class 3A is <5mW. Can it burn anything?
For burning tricks, you can light matches unaided in a coupe seconds or less with about 100mW. I can light firework fuses with my X105 and a focusing lens. I haven't tried it without a lens yet... Lighting a candle? Just a plain candle wick won't burn unless you have a couple WATTS. 100mW lights matches, burns holes through thin plastics (I burned through a black plastic spoon), burns paper (dark colored or sharpied), pops balloons no problem and can sting skin. To burn through a tin can I think you would need at least 10W (10,000mW) and that means it won't be portable and most likely IR.

I reviewed my X105 here, the video shows most of the burning tricks you can do:

if its red, you wont feel anything. but it will still light and burn darker surfaces... Green is different story though...
