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 !!

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 :)

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

Those are some beautiful beam shots too.

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:

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:

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?

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.

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.

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...
