Re: Thinking about buying a laser pointer, anyone have a lot of experience with them?
I own 2 lasers, a green 30mw and a red one at 227mw and the green one is the one I use the most since its beam on a full battery charge is much brighter than the red's.
I pretty much bought the red one cos it burns stuff and the green one for my astronomy interest.
The green one with project a dot as far as the eye can see, same as the red one, but it's far easier to see at night, I've projected the red one's dot onto a mountain about 8 miles from my dad's place, and the dot was several feet across at that range.
I paid £30 for the green and £50 for the red and have owned both for about 4-5 years, the green one is a lot more sturdier than the red and I've dropped it a few times in the past and its still working fine.
I would Love one of those Blue 1W Lasers, the Arctic 3 Spyder or something its called, but they are very, very dangerous, apparently the blue laser light does not trigger the blink response in the eye or something unlike the red or green so there is much more of a chance of taking a hit in the eye and the eye not responding fast enough to protect your retina etc, And even getting a laser reflection in the eye off the Spyder 3 could be enough to cause permanent eye damage.
If you did get one, then definitely buy some laser glasses intended for that laser, they will cover you between a certain nm and reduce the chances of laser damage to your eyes.
There is a ton of videos of youtube of people burning stuff with their 1w blue lasers, I even watched one recently where a guy set off some black powder in a plastic bag taped to the side of a cardboard tube full of the stuff and it went off with a big bang, if he could do that at 100+ metres then I can't begin to imagine the damage you could do if you hit yourself or someone else in the eyes with that thing, even a reflection off glass etc could have devastating consequences.
--- Post Update ---
Here's some photos I just took and some I took when I was working a year ago in wales, I used the green laser to shine the dot onto a mountain side about 4 miles away and a Pylon about 300 metres away.
The other pics were taken of both lasers in mist on a long exposure.
And the last one is my cat chasing the green one in my old apartment.
The 75mw laser should be powerful for all your needs, it won't burn but tbh that's not a bad thing, as once the novelty has worn off from burning and engraving your name on black stuff etc, its just another laser tbh.
Apparently the 1W laser is so powerful if you kept it on a car tyre for long enough it would burn a hole right through, so if you feel like acting like James Bond, woohoo!!
