For a negative ground system, like blu's and reds, the spring would protrude from the tailcap end, and there would be an insulator disk, say ~.025" thick with a hole in it to only allow the battery button through to contact a flat contact below the driver PCB (or ecthed on the bottom of the...

Damn right! You may get away with it once or twice, but sooner or later your diode will end up fried! I have some fried ones for sale, very cheap... ;)

It's a "stepping stone" diode, watch out! :exclamation

http://www.o-like.com/b2b_cpinfo.asp?id=929 Actually looks like it could be pretty nice! Too bad my laser budget is shot for this year... :(

Yea, but there goes your Free Shipping ::)

Re:  A long title that offers no info about t $80 for 4.99mW! ;D ;D ;D ;D ;D ;D ;D ;D ;D ;D ;D ;D ;D ;D ;D ;D ;D ;D ;D ;D ;D ;D That's all I have to say.

Hope you don't mind my adding my 2 pennies worth here... Hmm. Not sure what you mean exactly. No matter what kind of driver you use, the power lost across the diode is being dissipated as wasted heat and ultimately results in some shortened battery life/run time and increased heat overall. I...

Re: 5min continuos burning with 4x BR to wood.128. Nice little engraving tool, eh?

Even if you CAN adjust the current, you still want to be very, very careful driving LDs directly this way. Never set the output voltage much higher than the diode requires at the needed current. Even though the PS may be current limited, the voltage output will immediately increase to the...

Re: Behold the fearsome predator! (750mW total@650 Would this be classed as IIIB or IV? :-? So, can you devise a way to converge the beams at a few feet? Man what a cool bug zapper that would be! ;D

Oops, adding Spyderz20x6 to mental list....done... ;)

Igor, any idea when the lenses might be ready to sell? :-? I would be in for around 10 or so.

That's a pretty creative use of Paint! Can't go wrong with actual pictures of components.. I modified it slightly to show another possible way of doing it so you would only need a simple On/Off switch, and it would add the "low ohm" resistance in parallel to the "high ohm" ones for higher...

Now we're talkin! :D

Re: GGW-H20L 6x Sled GB!!! THE EPIC GB THREAD LAWL Well stated, Ace82. Since there is no source, we don't know what the cost/diode should even be any more, anyway. I could live with a refund and start over later - no doubt anyone in for this long will be back when the 6X's ARE available; I...

Re: Another AixiZ 50mw 532nm(the new variety) revi Thanks, I can't wait to try this, mine is way off center, maybe it will improve the power just a bit more... :D Thanks for pointing this out. I was thinking "Man that Snoctony laser must be Huge!" :o

If it wasn't for the fact that I build all my own diode-based lasers, I would not hesitate to buy from members such as IgorT, jayrob, daguin, or Kenom. So many happy customers can't be wrong. :D

Thanks, I think it is important to have a good sense of humor in a public forum.. ;) As for accusations, I made none. But I am very suspicious of coincidence, like your suddenly popping in and taking over. Still there is room for plausible deniability there. But remember, denial is the first...

It's just that I thought you were buying a complete unit for $135, and now you say it is just a module and batteries and other parts, no host to even put it in. :-? I went to the site and pretended to buy a complete Red unit, and by the time I had all the options selected for a decent one, it...
