Re: FS:2 @ 445nm >950mW
What apparent temperature do you think is "time to turn it off" hot? When it's detectably above room temperature, when it's lukewarm like the back of my LCD monitor, or when it's hot enough to be uncomfortable to touch? Hard to know how much heat these can take. I've...
How do you guys say "18650"?
Do you say "eighteen six fifty", "one eight six five zero/oh", "eighteen thousand, six hundred and fifty", "one eighty six, fifty", "eighteen sixty-five aught"?
I know, it's trivial, but it would be nice to know how most of you answer when someone asks what kind of...
I highly recommend Rayfoss lasers. I only have a Blu-Ray from them, but for the price, they're AMAZING. Nice solid flashlight hosts with focusable heads. Consistent output.
The waterproof 200mW is awesome.
Jayrob's Stainless Steel 18650 kit is the absolute BEST host ever made.
Everything you need is right there.
The ones on eBay are the ones sold by DealExtreme, which I've heard are cheap and not very durable. I've heard that Merkava's are somewhat fragile as well, compared to Iknitsteel's.
I really like Iknitsteel's design and the thick material he uses, so I would still prefer to purchase one of his.
Re: **Closed Accepting Payments!** Official GB: LPC-815 Sleds $4.45 300mW Red Laser D
Now that the group buy is finished, I hope some members will resell a few of these. I missed the GB by a couple of days, but I'd love to pick up a couple.
Apparently you can't read the writing in my posts. Read my original post. I did several searches on the forums and Google, including one of "Class IV red diode" and found nothing useful, especially since the forum filters out "IV" because it is not three characters long.
Why exactly is it only possible to make plain old diodes that produce only a few wavelengths?
Why do we have to produce 532nm light with IR flowing through a crystal? Why do we have to produce 488nm light by passing a beam through Argon gas?
These wavelengths are functionally no different from...
