A laser 301 stopped working? Considering those are only like $5 I would just buy a new one. Not really worth it trying to fix it. The best you can do is check the battery contacts and make sure it has a solid connection. Does the battery seem secure inside the laser?

Unfortunately the Aurora is the only real option as far as presentation 473nm pointers are concerned. You can order one from laserglow based in Canada, or you can save a bit of money and order one from China over ebay...

Litecoin making a run now. Up to $170+ last I checked. Seems to have a lot more potential upside than BTC at this point.

Just pm him and get this settled. I'm sure they're just busy and didn't get around to sending the tracking or something.

Bitcoin up to $17500 now! I cashed out 75% of my holdings because this is getting too damn crazy. Covered my initial investment, collected a 50% profit on it, and I'm letting the remaining 25% ride to see where it goes. Go bitcoin go

I've had several of them going back 5+ years. The first time I wondered if I'd somehow ingested a psychedelic drug or something as I saw all these multi-colored zigzags going through my vision. After about 30 minutes they faded away and I was left with a minor headache for a few hours...

Something like this might work well for you https://www.ebay.com/itm/371823927689?_trksid=p2060353.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT&afsrc=1&rmvSB=true Not us based, but it's cheap and does the job. See my review here...

Well, that's something I gotta clear from my history.

Woah, why all the rush to a PP dispute? When I got a defective spartan from DL they worked with me and sent me a new working one. I highly doubt they sent it to you in this condition, it probably just got a bad bump while being shipped. These things happen and it's unlikely there was any ill...

Idk, it seems pretty resilient so far. That drop from 8k to 5.6k recovered over about a week and seems like it shook off the weaker holders. I agree that it's a ridiculous bubble, but I have no idea when or if it will pop. Might take certain governments banning it or something like that.

Hey all, just wondering what you guys think of the recent Bitcoin craze. Do you think it's truly gonna be the future and go to $100,000+? Is it all just an exotic ponzi scheme which is gonna collapse in spectacular fashion any day now? I do think the current valuation is a bit absurd. I mean...

Realistically it's gonna be ugly no matter what you do. You'll want a beam expander to get any kind of decent beam.

The diode and power level should be the same. The main functional difference is simply the duty cycle. The 638nm spiker will give you a nearly unlimited duty cycle.

It's almost like the Chinese enjoy keeping NK around as their psychotic guard dog to serve as a distraction or something. I mean I really start to wonder why they never just dealt with the problem themselves. It would have been easy for them to simply march on in and claim NK as their own, and...

What does this have to do with the NK situation:confused: I get that you dislike Trump, but he's honestly not the bad guy in this case. The insane sadist running NK is the problem.

Laserglow have some nice options for you. I like their lyra series.

If we keep delaying action then the Norks will eventually have viable ICBM mounted nukes which can hit the USA. At that point we're screwed. What if they just decide to start marching on Seoul and say if we intervene they'll fire a nuke at Las Angeles? Little Kimmy basically believes it's not...

I wonder if there's an inside source from the manufacturer who occasionally 'releases' small lots of them somehow:shhh:

I can't see any peace or improving the lives of NK citizens so long as Kim Jong Un lives. He'll have 3 generations of a disident's family sent to concentration camps to be tortured, starved, worked to death, and to have medical experiments conducted on them. He allegedly has teen girls plucked...

I currently have a 473nm and a 515nm to compare it to. Seems like it ought to land right between those two colors. I'm hoping for something comparable to the color of my long gone argon laser. I loved the color of that thing, but not the huge, bulky, power hungry package.
