Valparaiso until August, Orlando August-May

I live about 30 minutes from Navarre in the summer, and about an hour from Melbourne during the school year.

My protection is more important than that of a dog's. If I had only a laser to defend myself, I would use it. If I had only a gun to defend myself, I would use that too.

Honestly, if you start with something very powerful, especially like 1W, there WILL be safety concerns. You need something to practice with. None of us here want to endorse you saying "I wonder what happens if...." while holding a 1W laser. With a lower power laser, you might get away with a...

With OD 7 I can see the a small dot well on white surfaces or any other surfaces. I also have accidentally received direct reflections from the laser beam into the goggles, and it was scary (noticeable) but very dim and definitely safe. I can imagine OD 8 would not be much different.

Wow dude. You aren't more "tolerant" than anyone else. It's simple science. You've got cells in your eyes, and they are getting demolished by high powered radiation. You don't have a stronger retina than I do or some nonsense like that. If you have been viewing a 1W laser diffuse reflection...

Hey, cool down. I'm not telling him what to do at all. I'm giving the advise, that IN MY OPINION (as this was stated in my post) he should start with a lowered powered laser because I think that is the safest approach. If he doesn't agree, that's fine. As a matter of fact, my post did EXACTLY...

Uhh, I'd start with a lower powered laser first. Please don't jump into the higher powered laSers without proper safety education which can be gained by reading this forum.

I think this is not a good idea. Also, the seller is making tons through this. He's selling his laser for $400. I wouldn't spend more than $270-300.

I did mine back in July...No email and got my shirt. I just got an email...they're sending me another.

Nope.

Just use the laser outside only, and shoot it either into the sky or at objects not in your immediate vicinity. That's all the fun of "viewing" a laser right there. If you want to get a laser for burning, most people won't get a 200mW green but rather a laser costing $200 or more, so dishing...

Diode's cannot perform any type of locomotion autonomously, so I'd say the chances of your diode walking are quite slim. However, I would suggest lower appendages or perhaps a motorized vehicular device of some sort to assist you in your task.

I've also noticed significant differences between a Coherent Fieldmaster and a Newport.

Qumefox is right, without IR cards or a IR scope (which is only for the dot...) you can't see an IR dot. The beam itself is even further out of the question.

If your goggles are protecting you sufficiently, you should not be able to see the beam. Here is how I balance admiring the color and having fun burning indoors: At night I often shine my laser around outside - that allows me to see the beam and have fun with that. Then indoors, I always use...

So through my work with the Air Force, I've been granted access to the SPIE library, which has a ridiculous amount of resources that I personally have found very interesting (I have a few of their books myself). The link seems to be working for others, so for anyone who wants to read through...

Thank you! It's simply the one from Jayrobs kit. If you want a true DIY, it may be fun to scavenge for your own parts, or create a heatsink with a lathe - but for me atleast, with no skills like that, purchasing the kit was the best option.

Never heard any bad things about Rayfoss. Using a sharpie should be fine, but I think it's still inferior to black baloons. The label should say whatever the power is. It's not an issue for you because it's not illegal to own one, just to import it. So as long as Rayfoss expected to pass...

In my experience the more powerful you go, the less the brightness increases. For example from 5mw to 100 mw of a green, you might see an incredible increase, and then less as you go along. Yes, the 400mw will be noticeable dimmer than the 1W. No, it probably doesn't matter. I still would have...
