Just got my meter today. Works perfectly. Shipping took 4 business days. If you're thinking about buying one, go for it! Thanks for the sale, nospin!

Is this on DTR's site: https://sites.google.com/site/dtrlpf/home/diodes/3-8mm-650nm-300mw-diode what you want?

Re: FS: ~940mW 635nm Kryton Groove & ~580mW 405nm in SS Host If Willjoe21 doesn't come through, PM me, I'm interested in the 405nm one.

Re: COCONUTS Uranium Marble Bulk Going out of Business Opportunity I'm also interested in a smaller quantity, around 10 1 inch marbles. PM me if it is possible! :)

Here's information on how to calculate your own lasers' hazard distances, given power, wavelength, and divergence. Useful if you have measured your laser's exact specs :) Page I got this from: Laser Pointer Safety - Laser safety calculations

Well you know how when you go to parties there are a LOT of balloons? Every single time I am in that situation I think of getting an IR laser that has a bit of range and power and then popping a lot of them from a few feet away while people are near them just to scare the sh*t out of them. Never...

Re: FS: CNI 1.5W 532nm Green Laser Module, Analog Modulation Interested, PM sent.

I like how on the 500000mw mentioned in the op, the specs say it runs at 7 V 1.1 A The post contradicts itself... 7.7W power consumption for 500W power output? I wish I could create energy.

Well, if you don't mind using IR, then a 40W or greater CO2 tube would be perfect. :) But you wouldn't want any random people walking around that without eye protection. And it will be way too big to fit inside a phaser. Ahh well, we just don't have a good enough visible single mode diode yet.

Don't those new 3.5W diodes have horrible divergence? I think it is even worse than the 9mm 1.6W rated ones that we usually push to 3W. It wouldn't work well at 7 yards. I've popped a balloon with a 405nm 700mW at 120 feet. Targeting was extremely easy as well, I could see the dot no problem in...

The more powerful NDB diodes that operate at 445 or 462 nm have horrible divergence, as the diodes are multimode. Your best bet for a distance burner would be with a 16x. Although, I would recommend setting it at a moderate (not the highest) current, as diode life is very important to me. But it...

Embedding a video is simple, you just use the [ Y T ] and [ / Y T ] tags (remove the spaces between the letters inside the [] brackets). Between the youtube tags, you put this part of the URL: URL: https://www.youtube.com/watch?v=PiHKNvmbto4 Part...

Of course, I don't plan on running it longer than 3 min on/off duty cycle. :)

Hello :) I finally got my Arcane 445nm back from Thejoker301 yesterday. Back in January/February, some of you may remember the thread I started about how the old diode died. (broken diode window) Joker provided outstanding customer service, and was extremely patient and understanding with me...

Yes, I know, usually they aren't like this, but all we can do is to wait and see. I'm hoping that they don't delay too long.

Same, mine also is still at order received. I ordered on 3/29 just for reference. Hopefully they process soon, but according to the page (where you add U to cart) their supply has been delayed. Hopefully they ship before this week ends.

$250... That's so expensive. :( Although it is one chunk.

Just a collector. Thanks for the link though! It's an interesting read.

I was just browsing the United Nuclear site, and found that their PURE Uranium samples were back in stock. $49 for 3-4 grams. This link Personally, I've been waiting a long time to get my hands on a sample. I bet they'll only stay in stock for another week. I already ordered a sample. Can't...

Just curious, 99.5% pure?
