I just found a really helpfull way to use a laser as a tool.

Earlier this night me and a few of my friends where outside deciding on how we where going to set up our halloween decorations when we all smelled smoke. after looking around we couldnt find the source of it, but it was getting stronger.
so, thinking of how my laser looks when i used the fog machine i pulled out my ol greenie and shined it into the sky. to my amazement i could clearly see a layer of smoke and by moving it around i could see where it was thickest.
we saw a nice cloud of smoke that would normaly be hidden by the shadow of night just light right up from behinde the trees about 1/4 mile away. we ran over there and saw that someone's car was on fire. but without the laser it would have taken us much longer.

i guess a spot light would have worked, but who carries one of those around?

Nice work.



Now, as long as they don't come looking for you when they think your high powered weapon set the car on fire with it's beam of pure energy. No good deed goes unpunished, you know. ;)

Hello All,
I use my lasers as tools a lot. The 405nm is good for rockhounding as it lights up flourescent minerals. It also works for verification of currency and IDs.

The green is useful for line-of-sight stuff like triangulation, distance and height calculations. (i.e.- point the laser at the top of an object and measure the angle and one can calculate the height. Doing the same with a compass and map can help triangulate one's location...)


cheers,

Wouldn't it be cheaper and more efficient to use a UV LED flashlight instead? :-/

I have used my greenie in a similar way before.

Whenever I smell smoke in the house or outside that I don't know where is coming from I just point my laser around and it quickly finds the source of it.

Yes, actually... It's usually my mums cooking lmao.

I can usually smell it and find it before the smoke alarm goes off.

I may be wrong, but normally, cooking is done in the kitchen.
That would explain where the burned food is.

Good job.

For me, not so much as-

1) A good UV flashlight/forensic light costs as much/more than my laser cost to build.
2) My lasers use rechargeable batteries.
3) I've got several cheap UV flashlights. None of them light things up like the 405nm does.
3) Anyway, my pockets are taxed enough with all the crap I carry around. (I need a utility belt like Batman had...)

De-focusing my 405nm into a 'spot' works just as well... ;)

cheers,

Try adding a diffraction grating to it as well when fluorescing minerals, etc.

Peace,

ROFL, when my mom makes pizza, the smoke alarm always goes off. But when there was a bunch of smoke from some burning oil and a bunch of candles, it never went off. ;D She also left a tea-towel in the oven one time, it caught fire, lol.

Anything sets our alarm off, its tempting to put the alarm in the oven and see what happens. It's a bit slow but anything sets it off.

How exactly do you leave a tea-towel in the over :-?

Not at lamborgini's house. They evidently make oatmeal in the bathtub, and broil steaks in the dryer.
