It's a nice design, and one of my favorite wavelengths. As a big fan of small copper hosts, I'd like to buy this if you still have it.

The damage from diffuse light drops off very quickly, you're right. I don't mean to imply you in particular got hurt from it. The dangerous scenario I had in mind, not that you would do it, was staring at the dot up close. If someone looked up close at the dot, like when burning something...

There is always going to be a hazard of reflection from some angle. Most surfaces, especially indoors, can reflect at least some of the beam. With proper goggles I have been protected the times that I notice the dimmed dot get brighter for a moment, which was at least a partial reflection. The...

I'll take 4 of them. And no, they don't come with drivers. I think I'm going to go with something similar to the design in that thread up above. I would think the heater would need to supply less power after the heatsink is warm. There's no built in measure, so it could be difficult to keep the...

I agree, that's a sleek look. You need something decent around one of those wonderful higher power diodes. This looks up to spreading some heat. The focus adapter is another nice touch I've noticed his builds do well. How have you found heat sinks to compare with dissipating fins vs unmachined...

I'm sorry if my post came across as complaining. I intended to add some context that this is indeed a quality build rather than one of the common, low quality 301 models which was first suggested. I hope this would help your sale by providing some of the details I would have found useful...

Those 589nm Spartans are a rare treat to see, and at a reasonable price. Anyone who is interested should take this chance, as they won't see another for a while. Also, that's quite the impressive 532nm you have there! Good luck with everything. I'm sure someone can find use for each of these.

I would make a note about generic 532nm pointers. They likely don't have an IR filter and can put out dangerous amounts of invisible light even when the 532nm is blocked. Even some reasonably expensive lasers leave this off, so you can't make guarantees about any of them without measuring...

I tend to agree. It feels a bit unwelcoming to me. We are trying to welcome people in and be familiar with them so we can best help each other. I think we do a good job of this, but I imagine our tone is misunderstood. Anyway, not to derail the thread, I think you have some good options in the...

Here's my leopard gecko staring down some lunch. I'm reminded of Jurassic Park when he's hunting them.

Beauty of a device you have there. I'm always impressed just how bright a watt of green is. I'm also impressed with the battery quality. They're under quite a load. Do you ever see the voltage dip when you turn on the beam?

Looks very sturdy with plenty of metal to absorb heat. Badboybilly has made quite a few nice looking hosts so far. This looks able to handle as much as the high power NUBM can dump into it. Enjoy!

Re: FS: Sanwu Laser store - R/G/B handhelds x3 BE & Stainless steel "The Spiker" rele It looks beautiful. I think a lot of people are excited for this, and look forward to time/pricing information. I hope everyone is fine with that result, and that this will be a very worthwhile engineering...

Re: 2.4A X-Drive V6, C6 host, C3 host The 490nm diodes are amazing. I used to think the most even blend of blue and green was around 500nm. I now have a 495nm that is a wonderful color, but still identifiably green. The 490nm I recently got from DTR is pretty much the most "confusing" as to if...

Re: 2.4A X-Drive V6, C6 host, C3 host What would you say is a common shipping cost for a small package from Canada to the US? I'd take the C3 unless it's going to be more than double the price after shipping. I guess that's pretty likely, considering it's across borders.

Wow, that's some nice work there. I think you've been doing well in your excursion into powder coating. If I didn't already have two things going with this diode, I'd be all over this. Wherever it goes, I'm sure they'll enjoy it.

That is an excellent visualization of why some combinations of colors can give white, and which are closer to a true balance. The gamut of what colors a laser combination can make is the section between the input lasers which can vary from 0-100% power. In the case of two lasers, this is a line...

Do you have any details on these, such as a model? I'm also curious as to the price you would want. I would take the ER:YAG if it's reasonable. I see a listing on Ebay that looks like it might be you. Alaskan is right, though, you will get more responses if you have pictures.

I have used razor blades stacked up side by side before as a beam stop. Pretty much as dark and matte a material (no specular reflections) as you can get is best. I'd recommend taking a look at this thread too: https://laserpointerforums.com/f44/diy-beam-stop-dump-91837.html

Re: FS: 495nm drop-in module @ 120mW I got mine in a 10-pack for $10 off Amazon. That particular listing is gone now, but I see Aixiz has some for $2 each: 3 pin socket mount for laser diodes, AixiZ
