LPC815 outdoor beamshots

[dreu]

my first DIY red laser using LOC diode from an LPC-815

pointing at a cathedral which is about 1.86 miles (3km) away:

closeup :

and a picture of the beast:

let me know what u think!

 

[eytyxhs]

What the f^ck? Really?

You did great job on That power Supply. I see you put an adj pot! (or not?) :beer:

 

[Blord]

That looks like a bad-ass machine from a sf movie.

Sir, the aliens have landed !
Activate the machine, shoot them back where they came from !!

 

[dreu]

at first ther was an adj pot for testing purposes, yes, but i ended up shorting it because it was crappy and all i want is to have maximum output power after all

 

[sinner]

Therefore, A BIG SCARY LASER!!
Very cool man , this is just good old fashioned DIY power!!

 

[LuxorLasers147]

This build looks really scary and powerfull!
420mA?

 

[T_Warne]

Wow! You get a 10 out of 10 for creativity and style!

Those are some beautiful beam shots too.

 

[TomD]

Stellar shot, and a much stellar looking build.

30 second exposure time into a cathedral? Didn't you get any knocks at your door or something? :angel:

 

[Just4FunReally]

That's the best looking beam I've ever seen from an LPC-8XX... You sure you're not just yanking my chain? Maybe the 30 sec exposure has something to do with it. I love the color it produces (the diode) but it has never been too visible to me. Maybe because I never take it outside at night.... :beer:

 

[TacoHerder]

wow, what a beast. This build looks epic! The pictures are so clean too. +1 for you sir, keep up the good work :beer:

 

[n2stuff]

At first I thinking photo shop til I saw the star trails. Yep it looks like 20-30 sec. exposure. Very nice build. But are you using a driver for the diode?

 

[Seoul_lasers]

Great beamshots.. +1 !!
I wonder how the efficiency would be if you switch to an all copper sink?

Nothing in your pictures is photoshopped. Just long exposure.

 

[ped]

Anyone???

 

[TacoHerder]

The shutter was open for a period of time. That's a star, it has moved a bit during the photo shoot. Or a satalite maybe.

 

[Eamon O Regan]

If you were pointit's west, it's the planet Venus, it's the brightest celestial inject in our sky excluding the sun and moon.

 

[dreu]

thanks everyone!
the beam was visible to the naked eye but it wasn't that bright, of course the 30 sec exposure helps

@LuxorLasers747: 420mA indeed. LM317 driven...
@Seoul_lasers: i dont know if another sink would change anything, it doesn't even get a little warm. i think it's just a little oversized
@ped, TacoHerder & Eamon O Regan: it's just a lens flare! because of the bright spotlight that is shining diametrically opposite on the picture...
