How could FP sell a faulty diode if it came straight out of a working projector?
How do any of us but the seller know how much life the diode had left in it?

But how it ?

It's a fact that, IIRC, around 5 % of diodes are duds. Or will be duds in few minutes of normal operation.

You cannot influence that.

You can't power every diode for 10 minutes at 1 A to ensure it's good diode, before shipping it. That way a customer (who tries really hard to be a d?ck, for example) can scr*w with the seller.

The customer there is fictious example, not meant towards any of you - just to avoid uneccesary language barrier caused broken noses here.

Who knows. anything is possible. laser diodes are very sensitive to ESD. they have to be desoldered and that imparts heat to the substrate. maybe it had issues and the heat or ESD damaged it. before i started working with it, I soldered a Lasorb to it to help mitigate ESD risks. its not like it was taken right off the line and was brand spanking new. it needs to be desoldered and mechanically removed from the projector.

some people put jumpers on the pins thinking this is going to help in some way. it only helps to protect the pins. the diode will still be very susceptible to ESD damage.

But how it ?

Agreed. and even still, if you are selling things to the public you are now in retail and retail in the western world is expected to provide customer support, warranty, exchange, etc. it just makes sense and is the right thing to do. and these people are also making a profit. don't think for a minute this is charity work. they are making a profit. fine, great. make a profit. i have absolutely nothing against making a profit. but provide warranty exchange or be very very clear that you do not so people know what the risks are.

This may or may not be relevant to Person(s) selling Diodes harvested from a projector. I put this out as an EXAMPLE of the legal lingo involved, and for no other purpose. Lots of CYA here.

The rate of failure for the product is actually the reponsibility of the seller in this case. He's selling a product, if that product does not work due to manufacturing issues that is between the seller and the manufacturer.

I dunno about you, but if I order something regardless if it's from a company or a private party, I expect that product to be delivered as described. In this case a 445nm Diode was delivered that did not function (that is not as described). I'm fairly certainly he didn't advertise he was selling defunct and faulty diodes, he advertised that he was selling functional, working 445nm Diodes, otherwise no one would bother to purchase any from him.

If it was an issue with manufacturing or how he removed the diode from the projector then it's his responsibility, he screwed up. The only way to confirm this is to test each diode briefly before sending it out, otherwise there is no way to tell if it was a problem from sellers end or if the customer did something that caused a problem, and unfortunately that seems to be the situation here. As a buyer I would be pretty upset myself if I odered something and it didn't work but at this point there is no way to tell what happened to it so neither party is willing to responsibility since neither one legitimately believes it's their fault.

Personally in a situation like this, I generally like to see the seller step up and take responsibility since he did not test before shipping and can not actually confirm it was in working order before it was sent. That being said, there is unfortunately no hard rule about how this is handled particularly when dealing with a private party as this case does.

I was checking out the 12x 405nm i built into the SH032 host using jayrob's copper kit. its got a microboost in it. I was comparing it to the 445 in the other SH032 using FP's kit. Anyway, i focused them 16m (50') away onto a wooden fence. the beam profile of the 405 was incredible, especially compared to the 445. both use the jayrob 405-g-1- lens.

the 405 was quite round and clean and about 1cm in diameter with some flare around it. of course the 445 was about 2mm x 4mm. i noticed that these builds do not attenuate the 445 line, where-as the Arctic does cut off the ends of the laser output because the lens cavity is too long. this is why the Arctic beam will be narrower than with these SH032 builds. you are actually getting more power out with the wider beam.

The striking thing was that the 405 was burning through the wood, 16m (50') away! the driver is set to 555mA using a 5x1N5404+1ohm dummy load and outputing 720mW average.

pretty impressive. i am finding that for burning, the 700mW build is more of a burner than the 1.2W 445 build. when you focus these beams down, watch out! they will burn flesh instantly.

And how, exactly, is a shorted diode susceptible to static discharge? Are those charges going to jump through the front glass window?

No Pontiac don't you see!?

The Evil Static Monster is roaming the world! He randomly zaps all of your electronics and blames it on your stupidity or anything else that doesn't make sense :eek:

I was wondering the same thing ? where dose he get his info

Well it sounds like Plexus has not told the whole story, it seems he has burned up a diode and a driver and now want's someone else to pay for them !
I was almost ready to replace his 445 diode but then he told me (and I have him PM to post if anyone is interested) that he had the 445 diode lasing for about one hour befor it die'd so if he had it working for that long it was not dead when he recieved it !
Now he has come on here complaning that it was dead from the begining, I think he needs to get his story stright befor he starts asking for replacements.
I have replaced LD's befor and even twice for one member in the same host (don't lase me bro), so don't think I won't replace diodes if I think that is the right thing to do !
Now let me state this here and now, I will replace diodes that I think are bad but I will not replace diodes that some one blows up and and just wants a new diode for free, I don't play that game, I do spend a lot of my life time trying to help members that need it as I was once in that place of needing help myself, but I will not be run over and taken advantage of by someone who has never done this befor and thinks I owe them something because they bought something from me.
hell he dosn't even understand that a shorting clip will prevent static damage, and when I asked him what kind of static precautions he took when handeling his 445 diode he stated he had a soldering iron that was static grounded and a wrist strap but he never stated he used a grounded work surface, so I know he understands about static so what was that statment about shorting bars only protect the diodes leads :thinking: that was a pretty stupid statment !
and as far as making a profit from what I do :crackup: every penney and then some goes right back into laser parts or materials so I can help any one out there that needs it ! I do not take any funds away from this I never go out and have a good dinner with my funds or buy parts for my quad, every penny goes back into laser parts ;)
@ jay I think I would think twice about giving him an other driver for free as he obviously can't be trusted to tell the whole story, he didn't give any of you the whole story here so you could make a sound judgment about what realy happened.
Peace All...

In my past expierience any time I have bought certain electronics parts they state that there is no warranty once they are installed. I work on a lot of equiment and we do not warranty timers, diodes, rectifiers and certain circuit boards if they are installed by the customer.

This hobby isn't subject to the normal business practices. For one, how can you be sure it was FP's harvesting that killed the diode, and not your soldering and assembly? Secondly, you've proven yourself easily capable of mistakes from your experience with Jayrob's kit.
If FP had sent you a fully assembled module with the driver set, and attached to the diode, and it arrived DOA, THEN I would agree that it should be replaced. This isn't wal-mart where you can break something and bring it right back for a replacement.

As for your ordeal with Jayrob's kit: Better luck next time. there was nothing other than your own hands that caused that problem. I've assembled my fair share of lasers that used a pill and a heat sink.

I can't speak for jayrob as i have never done any business with him.
As for flamin pyro, I've spoken with him over the telephone, and have even received random envelopes of goodies from him in the past. Hes always willing to help.

I know i'm quick to fix any problems a customer may have with something they have bought from me, but ONLY IF IT'S DUE TO MY PRODUCT.
One example is DTR's heat sink not fitting, that's a flaw in my product so I replaced it.

I still can't believe your trying to hold jayrob responsible for your mishap.
If i go out and buy a trailer for my lawn mower, and then break the trailer while trying to hook it up to the lawn mower, I'm not going to call the lawn mower manufacturer and demand they buy me a new trailer....

I don't snap at people, but you make me angry.
Screwing up, killing diodes, and losing money and getting angry about it is all part of this hobby. everyone goes through it. The only difference is, we get angry at ourselves for screwing up and then we try again. We don't blame other people for our mistakes and try to get it all replaced for free.
and no, I don't sell stuff for a profit. i think that's obvious from the prices....I'm cheaper than a chinese laborer

RAWR!!!!!!

OH BTW, you need to move your post in the laser pro shop, IT'S IN THE WRONG DAMN SECTION!

Come on Jay everybody knows if you diode gets struck by lightning only the Lasorb can handle the 1.21 gigawatts.:p
