Well honestly, my laser hobby is in a pause and i infrequently enter the forum as a guest. But idk i just decided to log in and post for once. The forum is not what it used to be too, the topics are a bit different and there hasn't been any significant advancement in laser technology for a while...

This guy behind denodan account seems like a bunch of ghost accounts WL created back then, to try and boost their sales. Obviously, they didn't realize that folks who lurk this forum are not particularly dumb, and we saw through all their bullshit right away. :tsk: Btw, its not the first thread...

I don't know if this is considered advertising, but i just thought i'd share this with you guys. I have followed his projects for quite some time, which include a pretty sick railgun. :) Sam Barros' PowerLabs!

Reminds me of a weapon from unreal tournament or so. Very impressive weapon. +rep

LoL :D I've traveled from cali to mexico city back and forth about 20 times? Something like that.

:p atleast five characters Oh and very interesting calculations. :pop:

I also need 3x setscrews :)

lol xD

:pop:

Seems you guys like geeking out on thermal conductivity :) Yes, we all know the numbers don't lie, and know copper overall manages heat better than just about everything else. I was thinking however, how about the mixing of metals? If any sort of combination would pose an awkward benefit. A...

what's the name of the lens o:?

With $700 budget, i would look at something like this: 200mW to 700mW PL-E 532NM Green Lasers. The 300mw version is more than enough for star pointing. At night, you will get a very solid, almost string-like beam. And spend the rest in... moar lasers :D RIFLE 445nm - Full 1.2W Focusable Blue...

i concurr, post some pictures of the unit.

That's interesting, most modules use 3~4.2V What kind of flashlight was used? it looks like a maglite solitaire.

Perhaps you can replace the resistor(s) to yield the desired 1.8A?

Umm, they sell it at home depot i believe. its something like this: Ideally, it could have been done before press-fitting everything, but well, tape the aperture of the laser to prevent the window from being sprayed.

Very slick build, you should mirror polish the host :D Or you can also go with the sleek satin and spray some clearcoat over it to avoid fingerprint marks on the brass.

"I also had a GB planned for more modules & heatsinks" Had :( Im really sorry you had to lose money, shit happens.

I need to be on here more often, omg!! *geekgasm* The plexiglass glows so nice when its on. *-* Well, i think the fan is adequate, more akin to a turbine with 40db lol, but this build seems to be overkill in every aspect. You could slap a TEC as others have suggested, which would shave off...
