Okay, I hate to be the voice of dissent here (actually, it's in my nature. See username. . .) BUT, It seems to me that we are on a very slippery slope regarding these diodes and the lasers we can build with them. Do they have the potential to be uncommonly dangerous, as far as lasers go? Sure...

Re: ROUND 4 SOLD!! - CHEAP 445nm 5.6mm (true-blue) diode group buy. Payment sent. Thanks! :)

Re: ROUND 4 - CHEAP 445nm 5.6mm (true-blue) diode group buy. Oh, hell. I'll take one, I suppose. Sign me up!

That build really doesn't suck at all. Great job. I find myself envious of skills and toys:D

Sorry to chat in a sale thread; I just wanted to say that thing is cuter than bug shit:)

First, what batteries would you like to use? Second, the new Micro Boost drive is a boost only driver designed primarily to deliver the high voltage requirements of 405nM diodes. Check out the Micro Flex drive. It might suit your needs better. Or a rkcstr, depending on what batteries you want...

A simple one is to reflect a laser off a CD. The reflection will be a series of spaced lines. The spacing gets tighter as the wavelength of the laser decreases. You can use this method to differentiate between similar wavelengths, such as 635 vs 650. Consider it a stepping stone to a real...

Re: Aixiz 15mw 532nm I meant I would put the good driver on the good module and can the rest :)

Re: ►AMK GB◄ ~ SF-AW210 Diodes $10 Each In light of that (^) would you please place my order of four sleds in batch # 2? Payment upon confirmation, of course.

Re: ►AMK GB◄ ~ SF-AW210 Diodes $10 Each Just to be clear, I still want four sleds out of batch three. Thanks! :)

Re: Aixiz 15mw 532nm I'd swap out the drivers and see if I could get that "insane" beam back. I hate artifacts. . .

Re: ►AMK GB◄ ~ SF-AW210 Diodes $10 Each Payment sent:)

Re: ►AMK GB◄ ~ SF-AW210 Diodes $10 Each Screw it. I'll take the one remaining from batch one, if it's still available. Diode only, please. I'm still good for four sleds from batch three. Damn youthful impatience. Confirm, and I will pay.

About 7/8" or 22.225mm

Re: ►AMK GB◄ ~ SF-AW210 Diodes $10 Each I, too, would vastly prefer sleds over (partially,) extracted diodes. I haven't played with SF-AW210 optics before. I'm willing to pay a bit more. It should be +$3 to my order of 4 sleds, correct? Let me know.

When people go tanning, they sometimes place a sticker on their body so they can see how much they tanned in that session. One popular sticker shape is the Playboy bunny.

It'll smoke black leather out to three feet. I put the actual focal point where the beam is narrowest at two feet.

Re: ►AMK GB◄ ~ SF-AW210 sleds $10 Each I'll commit to 4 sleds. Thanks a bunch! (I'll check back, but I might need a PM when payment is due. I'd guess most of the heavy hitters got in on the first two. Might be a while.)

I actually don't know. I've been using a smoke bottle to view the beam. About a half turn of the lens from being absolutely tight, and the laser will smoke leather at about three feet. Any further adjustment brings the focal point closer to the aperture. I suspect that it doesn't focus all the...

So, after my 6x died, I dropped a PHR in the host (Jayrob pocket mini + copper heatsink,) and decided to abuse it a little. I set the current to 140mA. I now know that it's currently putting out 135mW after a 405-G-1 lens. I've been running it hard, pretty much ignoring duty cycles (it has been...
