Bluefan, I know it's nothing new but still very interesting and if nothing else, has some useful applications. While reading a bit more and searching for similar studies I cam across this article which is also super duper cool lol BBC News | SCI/TECH | Light stopped in its tracks

Scientists drag light by slowing it to speed of sound Not really sure if this has been posted here but I found this very cool. Basically they slowed a green laser by shining it through a ruby rod spun at up to 3000 rpm, causing the light to slow to the speed of sound they say and redirecting...

Thank you all for your input. I'm glad that it's most likely something easily fixed haha. I have been real busy and haven't had a chance to fix it yet but will soon. Again thanks for your help :yh:

Thanks for such a quick response and the info. What type of spacer did you use?

I've recently noticed a "hole" down the center of the beam of my 445nm build using an A140 diode in a JayRob host. When I first noticed the "hole" I also heard a slight jiggle and narrowed it down to the lens assembly. Turns out the retaining ring on the back of the assembly had come a bit loose...

Just a heads up to anyone thinking of buying from DinoDirect, I have ordered a flashlight and i got it but it took over 2 months to arrive (I live in Texas). I ordered a set of bucky ball type magnets for $18.99 on December 1, and after not getting a tracking number for 4 weeks I emailed them...

Hmmm, that could explain why I got it to work a few times but it was pretty unreliable. I posted my last post then tried and it was really difficult to get any particles trapped. The first few times it would only work for about 5 seconds too.

Old thread I know lol but I thought of this thread while I was burning and cutting matches with my 445 set at 920mA a few minutes ago. Seems to work pretty well and because I like blue a lot more than red, I thought it was amazing having a blue "tractor beam" in my hand haha. I don't have the...

Jay, I'd have to agree that nothing else will do. Concidering this is about 6-8 times more powerfull than my other commonly used portable lasers, it's deffinately a new treat. And I gotta say again I love the host, I'll deffinately be doing business with you in the future. And Jib, yeah you'll...

I just finished my build in Jayrobs 18650 host. For starters, thanks Jay it looks sexy lol. As far as the lens goes, the beam is nice and rectangular. Had it at about 650mA then turned it up to 920 about 20 minutes later haha. I'm nearly sure that I have the right lens as it does look like...

I just got my replacement lens in the mail today along with my flexdrive so I plan to finish mine tonight. The new lens I got today deffinately does not havethr blue reflections like the normal red lens does, however the golden reflection is only slightly golden. I don't have an LPM to test but...

Quite a sexy build there. I like :D

How much is this discount?

Gotcha. Well that works for me for now since, like I said I'll be setting mine at about 1.1A.:yh: Again though SHIN, thanks for your help.

So far I'm just waiting on the driver to get here then I'll get this baby goin lol. I'm working on the laser goggles issue atm and will make sure to get some before I do anything other than star gazing with it, after checking for planes of course :D My main interest is beam and color

Aha. I appreciate your help SHIN. Now how does accuracy work on the dummy loads? By that I mean if the voltage drop of the dummy is different from the voltage drop of the diode, will that effect the loads accuracy? Or does it just need to be as close as possible? Why exactly can't the...

Great walk through Jay. I'm working on your 18650 kit build right now and it is MY first legitimate build. So, that being the case, i can appreciate the helpfull hints. You've done many posts on build hints and tips and helped so many people build their lasers that in my opinion, they can't all...

Alright well I've got a question. Will 1n5399 diodes work for a dummy load for a 445? I couldn't get enough 5404s near by so I looked around. I came across the 5399s and they are rated at 1.5A with a voltage drop of 1.1V at 1.5A. Sound ok? Also I'll be using a 2W 1 ohm resistor. So my question...

I seem to have lost the loads I made for BR and red, and now that I'm getting ready to build my first 445 I think I'm going to go ahead and build one of these loads to use with all my drivers. And because it's more substantial than my last 2 loads I'll be less likely to lose it haha

Well for a beam profiler I don't see why it wouldn't work although it would take quite a bit of work. Not 100% sure I understand what your plans are though. Maybe I'm just missing something though lol I'm tired and at work.
