Well I'd be interested in knowing basically, what the difference is, it looks like the body is ground, and the center post is positive? So each would use a ring-terminal pigtail soldered to the next in series to follow Cyparagons schematic? I'm just wondering why you are saying get this type...

I found some nice items at the Surplus Shed, but they said that they couldn't coat them in house, but could grind them. I don't know about that, if they can't actually coat them it just adds another step. It's funny on one of "Edmunds" envelops containing a lens I saw Anchoroptics.com, and...

Been meaning to reply to this. A few things briefly: One; I'm partially confused. :undecided: When it is talked about placing the multimeter in the load, you guys are talking about the shunts, etc. I have a Klein, MM1000 multimeter. Probably the shunt type like mentioned, I assume. So what's...

Hi fellow LPF members, I have been faced with a small challenge lately. That is, finding a large positive FL lens, of aspherical type, that is 88mm total OD (about 80mm minus its mounting flange), and back plane surface focal point of anywhere between 53-62mm. 60mm back focal point would be...

"Necropost"? Have you ever read an old book, or was it of "necro" value by the time you discovered it? :D

I like Cyparagon's diagram because I see clearly: 4, 6, and 8, for 2V, 3V, and 4V. Where can I get some rectifiers quick? Heh...I have an audio amplifier board a friend gave me, anything useful on those? 12 Cree XM-Ls. That's what's powered. It could be two banks of 6A, I simply suspect each...

I have a 2" diameter PCB driver with a very large coil on it and 4 output leads. It is actually intended to drive 12 LEDs (pulled from flashlight). Now, I would like to test this driver for its maximum output on the Vf side. The old technique was a series of 4001 diodes from RShack, with a...

I managed to find a store on ebay from Australia that deals with crystal sets. I was hesitant at first to buy the higher end set. But then after chatting with the tech for some days I decided I would go for a cheaper package he had available. He told me he had obtained 600-700mW using a 3W pump...

It's nexbox..the kid who thinks he is the greatest vendor here with his hyped up yip yap. If I were you I would get a real job, and stop trying to live out some phony laser pushing dream since you acquired your amazing middleman. You're hype, you had crap with no support but excuses, lies, no...

Guys, I screwed up. I had bought 405 sleds, and 655nm sleds together. Well one of the boxes had a blue dot, I assumed it was the 405 sled, started studying it, and then when you mentioned here it doesn't knife edge, I take a look and here I am staring at the 655nm sled. Yeah the SW512 has two...

I just have a few of the SF-512w(?) sleds that have the decent 12x 405nm and 650nm diodes. Obviously these are tuned very precisely from the factory to read the disk, so my theory was that maybe it would be a good idea to utilize the sleds themselves for beam combining, mounting the sleds in...

Can the sleds be used? Anyone ever tried it? I'm going to soon so I will report back tomorrow.

Have NO fear. My signature is here! That better cap that bottle. :p

Re: Using factory 12x sleds for 405nm + 445nm knife-edging? Has anyone studied the drive sleds them selves, like SF-512WB blue ray?? It just looks so intriguing when i look at the sled optics. I'm going to have to look up 'knife edging' so i know when they are closely setup well and pros/cons...

I have some of the SF-512 sleds with 12X 405nm and 650nm(?) diodes. It looks like these sleds use knife edging to combine the beams into one output beam. Is this a true knife edge design for combining beams, or do hobbyists use a more efficient design? I'm just wondering if if is at all...

I am trying to get some 20awg power wire. What I want to get is a orange and black pair that is twisted (1 orange 1 black), or buy the two colors separate and twist them myself. I guess I would need something stiff enough to stay twisted, but still being a little flexible. The stuff used for r/c...

I have two sleds here I forgot I had. One is the S06j, the other is the SF-BW512p. Are these supposedly the same diode in each? About driving the 12x diodes to high currents. I am going to push them now that they are cheap. But, I can say that through testing, their lives are greatly shortened...

Sorry, I did miss that post. Here is what is odd about my results cumefox. Note that I am not contesting your accuracy now, just reporting my results. My first A130 diode at 1W and G1 lens showed no such thing. No wings. Not even barely. I had a bar output, say 4x25mm at 40 feet (note, visual...

Thanks for confirming. These wings are a major problem. I am talking like 5% or so of the output actually emits in the region of these wings, because they have their own very apparent beam pattern when shined to the sky at night. The beam looks like crap--you get a big spotlight effect, like...

Hmm. I'm finding it hard to get my point across in each thread that I ask this in. Wings. The old lens had huge wings next to the dot. Are the wings still there? The 405G-1 produces no wings. I'm wondering if it now looks like that, or what. :thinking:
