Better yet, that smoke was from black powder :D which I ignited with the laser ;)

it will still light fireworks, of course, just not as fast as with a good lens. Those casio lens "wings" probably shoot about 40% of the light off to the side :yabbmad: On a side note, do you guys think it's safe for me to light fireworks with a laser around other people provided I exercise obvious safety eg. "stand the hell back" and "I'm pointing this mofo at the ground for a reason!"? I figure fuses and grass aren't super reflective.... what do you think?

TheTeslaWarrior, it burned your desk? (which oddly looks like the same one my sister has) How long where you running it, and at what power?

I pointed it at my door for 3 mins before and it didn't start smoking, 900mA, was acrylic lens. Now I have Jays G-1 405nm glass, in a host, so I cant do those long runs :( I still have to go firework hunting, I may plan to create a little rig for my host for lightning fireworks...A simple clip that adds a thin tube with black inside. In short, a way to hide the laser. This way the only visable beam goes 2" long and then goes into the tube so theres no light splash. The only time you will get light splash is when you stick the fuse in the beam for under .1 seconds.

This way when I light off fireworks possibly at the show it self (many do this) I dont have to pay much attention where im pointing, because the laser only beams 2" into a dead-stop target.

I think you should focus the beam farther away than 2 inches, it would be really bad if fuse residue got stuck on the lens, that stuff STICKS.

running at exactly 1A I take it? Must be the type of wood my door is made of. Some woods burn slower than others.

exactly one amp is correct (ddl with 4 5ohm resistors in parallel). my desk is laminated i think, though i have burnt wood at those distances.

Since its a temporary deal, im gona hot glue a peice of acrylic to the aixiz module, since hotglue doesnt stick that good to aluminum.
I have it all planned out, will be fine :) So far I got it to work with a window on the side of a PVC pipe so when the fuse hits the laser, the window side (multi-layer filters) you just see a little dim light. While the laser is in the 1" PVC pipe, there's no blue light visable except for the hole for the fuse, which is dim anyways. Apparently the penny i used for the lasers stopper (dark brown one) is absorbing a lot of the light...This way, when the lens window is facing me, i stick the fuse in (other side of window) and have no worries for vision. The tube slides nicely on the laser, doesn't wiggle around, and covers it by 2 inches.

alright, good. I'm not too concerned about lighting fireworks with this lens right now because I HATE this lens. I couldn't care less if it got soot on it. But I wouldn't want you to get your nice lens all dirty :(
 
hi all...
I'm from Vietnam
I want to buy a blue laser diode 445nm 1W type, but do not know how much, hope everybody help .... thank all....

do some reading around the forum. There is lots of info, don't just ask right here. Read the stickies at the top of the general section of the forum.
