Dear Yobresal, appreciated laser. It hit over 740 degrees.

so I was looking at some Sony diodes in the 4000mW range, and noticed they were thermoelectrically cooled. I'd never heard of such a thing (nothing new about that), and I began searching for a cylinder variant to see if it could be used in a host. I didn't see any cylinder versions, only flat...

honestly I'd like to see fluorescent pink or indigo. I'm probably alone in that regard.

I think the uranium marble is a nice touch :) Good luck!

I'm considerably impressed by the fact that the 200mW label is extremely conservative. I like the idea of doing business with a manufacturer that understates their quality. It's sort of like that Engineer's rule for Star Trek.

its so bad ass! I'm not sure if I like the tininess though, I mean it has the EDC specialness of being small but the shape looks like something you could use on a much larger host. You got incredible power out of it, which is impressive, but I would also worry about it overheating. Actually, I'd...

three? is that all it takes? Wow. A yoda saber is easier than I thought... then again, I don't know anything about electronics. Do 1000mW greens even exist? I've only seen the Hercules and I don't recall it being 1W.

that's what was going through my head. At machine trades school, we had enormous lathes and mills and we normally worked with steel, so working with aluminum was something of a treat - your bits stay sharper for longer and you can make deeper passes. Despite that, I'd like to get a small lathe...

on the one hand, the minimalist in me sees a lot of steps I would probably skip, but on the other, the machinist in me remembers the endless hours dedicated to a similar looking piece used for an aluminum bottle. I think my favorite part of machining - especially with aluminum is the hologram...

I am grateful for all the advice and recommended styles. We recently went to a range with a glock 9mm and casings flew everywhere - a bit odd for me since I'm used to revolvers. I think at least one casing bounced off either my safety glasses or my hat. Meanwhile, in the booth next to us, some...

makes sense for the 510. The LDH-P-C-500 is 500 nm ± 10 nm, so between 490 and 510. If we are looking at 490-500, would that be sea green? I'm still trying to get a less vague idea of what the nm differences are in color... like do they correspond every +60nm or something, or is like a sliding...

That sounds like the PS3 diode mix. To me, the 445nm looks indigo and the 405 looks almost magenta, but I noticed while looking at some flowers the "purple" and "pink" aspects don't always show up on digital photography. I think these diodes are supposed to be sea green, judging by how close...

So today we went to a new electronics store, about a mile from downtown. We found an astonishing variety of pliers and capacitors, and even found LM317's in bulk, but didn't find any potentiometers below 500 ohms. During the evening, we found a Radio Shack with a huge variety of electronic...

Opnext blue laser diode for embedded device picoprojector applications - Laser Focus World I thought this was an interesting diode for people who are more interested in the color than in burning lasers. This one is 60mW, according to its maker, Opnext: But when I went to their website...

$50 isn't so bad, I think the hard part is getting someone who knows what they are doing to make a lens attachment out of it. I've seen My Yob laser beam on the other side of ultra white printer paper - which doesn't burn at all, but you can see the tiny blue bar, it's about 3mm x 1mm in my...

New picosecond pulsed diode lasers at 500 nm and 510 nm by PicoQuant I'm not sure if this has been mentioned yet, but in my quest for fancy new diodes, I tripped over this article, originally from July 15th and reprinted August 15th (3 days ago). edit: direct product source...

I've been looking into Laser lenses and I noticed with engraving lenses, they normally try to focus a smudge into a dot. I've also noticed the 445nm lasers produce a bar, rather than a dot. Is it possible to turn that bar into a dot, even it its only got a range of a couple of millimeters? I'm...

I'd love to get my hands on some 308nm UV diodes, but the ones I saw in that range were for several thousand dollars.

I've had to read tons of Nietzsche and Foucault but neither really give me the warm fuzzies. I rather liked the Tale of Genji and the Tao Te Ching, and found some amazing lines from the Mahabharata and the essential Kabbalah.

we just watched a video of melting solder with a 4W argon... Killer 4W Argon Ion Laser! - YouTube So I think if you are somewhere between 1W and 10W, you are in the 'melting solder" zone, you only have to get it to like 600 degrees. If you started by heating up some black metal surface, you...
