9mm kryton

Ok I don't want this to become an issue
firstly BEFORE I did anything I tried fresh batteries the diode was so dim it didn't even have a visible beam.
also how did you remove it from the copper module I saw it in without a proper extractor?
there was a multitude of issues .also Im not sure how the diode would have burned anything totally un- collimated even if it was putting out an estimated watt. first thing I did was measure the out put .
there was something wrong, the un heatsinked driver was getting so incredibly hot after a few seconds I couldn't realistically run it .
I had to press the diode in straight because it was sticking out.
all im saying is that there were issues . and I wanted to fix them and do what I could before saying anything. I wasn't even going to mention your name !
All ive done is replaced the solder joints and wiring using heat shrink and I dummy loaded the driver which I ran at charged battery voltage via my benchtop. the driver got SCALDING hot and dropped output very very quickly .when you tested it with your 18650s the diode was still in a copper module. so maybe something happened in your extraction? u said you had no purpose built extractor
I bought this because u sounded genuine and im sure you are being truthful about everything you have told me .Its just some of the things and methods ive seen to be used were asking for trouble.
I am happy to take SOME of the responsibility because I did know you had it in a semi kit form before you sent it and built it so it worked at a cost of an extra ten dollars.
I just want to see whats wrong now personally I believe the diode has been damaged.
Im no expert
I have posted the unit with supplied charged batteries by special delivery to PED
ITs a wait and see thing now . maybe its all down to me and if it is not only will I eat my hat in public ill buy you a beer and apologise

The only reason the buyer opened it up is because when he got it and put in working batteries, it was only outputting weak LED-type light. The soldering job was reportedly sloppy work, the heat shrink was tape, and you tried to press the diode with plier things. None of that is going to look good on you.

Also ive built several successful lasers and had my fair share of diode popping failures
It happens .
so Im not a total idiot when it comes to this stuff Only a bit

Livinloud · Jun 20, 2013

if the laser was received and worked perfectly then there would have been no need for repairs or even opening the laser up. Also from you sale thread i had a feeling you didnt exactly know what you were doing. you said you slid the diode into a copper module and slid it out with no damage at all and you didnt have a diode extractor. that means the diode wasnt making proper heat transfer with the copper module and you tested it with just the copper module. this is not heat sinked at all, a copper module is the only way to get a diode held in a heat sink, but is not a heat sink for diode testing.

I heatsinked it in a 9mm copper module and powered it on for like a second each time I took a pic, only got very slightly warm at the end of the "test". I shall lower the price to $100 with driver included, I am now selling this at a loss.

Here are pics:

exactly ! and these produce HEAT

Livinloud · Jun 20, 2013

that alone could be enough to fry the diode (even though you (OP) said it worked after this testing). diodes can work for a little while after being pushed too hard/over heated or they can die right away.

daawood123 · Jun 20, 2013

It was not sliding freely if thats what your thinking, there was resistance, knowing I had no press/extractor I did not want to damage the diode so I opened the hole up a bit to make it easier. Plier things, I meant G clamps (found that out on google) using a sort of makeshift press, it was a rod with a hole that went over the pins and pressed down onto the diode, however it was not very good it seems.

I am not passing all the blame to the buyer. I am just saying if it was broken/damaged when it arrived, best thing would have been to contact me straight away before having a play around with it. The problem may have been a simple one, such as tailcap switch wasnt working properly or driver wasnt making contact, however by opening it and tinkering with it I simply will not accept full blame for a blown diode. I sent it working, now it is dead. Again I am not attacking the buyer, or passing the blame, I believe it is my fault partly, which is why I'm still here trying to fix things. If I was intentionally going to scam him, I could have just stopped visiting LPF and carried on with life.

Also there is a lot of confusion over my methods which I described. It was not tested in the copper module, that was to show it emitted "light". I was not using full power batteries, after I had "installed" it into the kryton head, that was when I tested it, using my 2 18650 batteries. First I powered it out of the host, then again when I had assembled everything, both times the diode lit up as bright/powerfull as it should.

In response to a previous comment, a 1w+ diode will burn plastic uncollimated a couple cm away, so I am not lying about that.

I have a bad feeling all of you have a wierd image of a diode superglue to a driver with sellotape all over the pins and then pushed into the head at a wierd angle, I assure you, it is not like that at all.

I feel as if there is no point argueing over this anymore. I would wait and see what comes about after ped tests the diode, at worse diode will be dead, again I will accept some responisibilty for this, if diode is still alive and it is something else like anodizing (which I stripped using wire brush on dremel btw) then it shouldnt be too bad to correct.

Again I apologize to the buyer for all for all of this hassle.

@ Livinloud: When I took those pics, it was to prove to you guys diode was working. It is aiming at my camera. Am I really going to power it on fully and then point at my camera? It was not fully powered, I was using batteries that were not charged, they had enough voltage to power it on. I tested it was working again when it was assembled, because remember, first it was a kit, aka diode was not in kryton head, hence I tested in module. Then when I assembled I tested again to see if it was all wired correctly, just like anyone would do, and then I roughly checked the power by burning plastic couple cm away, it did this fine, and I was then sure it was over 1w or damn near close to it.

Would just like to add in my defence before shipping I put 2 18650's into the host (my only batteries that are fully charged) and connected a wire to the inner threading, the laser worked fine and looked and felt to be over 1.5w, it started burning holes on my rug, and this was without a lens, and I tested the switch on/off several times using the slightly dead batteries (still powered diode but weakly) and it went on off fine.

I did direct drive the diode while it was in a copper module also using the driver and again it was outputting a high power beam. When I sent it out it was working as it should, I would not sell anything I knew to be faulty to anyone. Heck if it was faulty I would have just got a new diode and driver for it and then sold it.

It seems to me the confusion is yours. Your claims are now dubious and force incredulity.

daawood123 · Jun 20, 2013

I am not confused, the batteries were not completely dead, the only batteries that are dead (not dead as in not working, dead as in no charge) are my 16340's which was my last set. I have like 8 18650's, some of which came from a laptop battery pack. Anyway, it was not fully powered, I am aiming it at my camera while photographing it. I would not point a high power laser at my ipod...

Right some of that sounds confusing, it was powered while in the module, yes I agree. However that quote is taken out of context, I was proving a point that it was not 65mw, anything over 100mw is high power imo, I did not say it was putting out 1.5w ~ while in the copper module. It was definately putting out more than 65mw though, That is what I meant. I can upload a pic of my multi 18650 collection if you guys wish...

Again, I accept the fact that I maybe should have not tested it in the copper module, however, I did not want to install it into the kryton head because at the time It was being sold as a kit.

Livinloud · Jun 20, 2013

How are any of your quotes taken out of context. Everything else was left in the quote. We didnt remove words or rearrange your quote. Thats exactly what you said and everyone can go back and read it. To me it sounds like you are back tracking and forgetting what you originally said. IMO I wouldn't say another thing and let ped figure this out since to me your digging your own grave, unless thats what your trying to do.

Im not on anyones side other than spectating and thats just my £0.02 (had to be different) so take it or leave it, I could care less

daawood123 · Jun 20, 2013

I meant taken out of context as I was talking about the power of it, as it was putting out 65mw and I meant I tested it and it was high powered and not 65mw. I wasnt accusing SBA of editing the quote or taking words out etc. I have not forgotten what I said, all I sad was the truth as honestly as I could.

Anyway I'm going to stop talking now as you say, like mentioned before I want to wait to see what the problem is with the diode before beginning a heated arguement.

midnighttattoo · Jun 20, 2013

when I got it It was 65mw full stop. and there was hardly a visible beam I measured it BEFORE I touched anything don't forget Id just got it so didn't wanna start whinging and sending stuff back its a pain in the arse .
If my NEW meter was that inaccurate and measuring that low then I must unknowingly own some 20w lasers.
remember my out put was measured and yours was guessed. Anything could have happened during assembly
u cant guess power I have got 100 mw stuff that I can make burn if its close enough.
Anyway im exited to get it fixed I adore the host so if I end up paying some over the odds so be it .

Now lets take a step back if you don't mind. I have waited to post here, but I cannot hold my tongue any longer. What makes it right for you to interject your antagonistic opinion anyway. You say your just a spectator than please just spectate. Telling Mr. daawood he is digging his own grave is less than a supportive statement, in fact that is a preconceived as guilty statement:tsk:. He clearly has been a gentleman during this thread so far so step back and let the processes unfold with out your harsh post.:wtf:

Let's not jump on the he must be trying to scam bandwagon just because that's what we do around here... cause it's not. We haven't seen any PROOf that this was the intent of the seller. I would suggest also before this turns into a flame fest that you just wait untill the seller is proved to be in the wrong before we drag his good name thru the ringer on this one transaction.

For the record I have had some dealings awhile ago with member daawood that went very well, he has always been very polite with others and has never wronged anyone that I know of. So let this unfold in a manner becomming of our members here.

If daawood wronged the buyer let he and the buyer work it out. If it comes back as a total discord then please conduct yourselves as people worthy of the LPF member badge.:gj:.

Sometimes it better not to have a post in every thread that has nothing to do with you it's called maturity. Being a spectator to 2 members trying to work things out would mean you were hoping for the best for both parties or did you want the seller to be a scammer and the buyer to be getting ripped off, this just for mere entertainment? I hope not.

I just ask for more consideration for fellow members, the BS around here as of late is not. Well crap I got to go get some work done. Lets just chill for the sake of the community OK.:thanks:

^^^here here. Lets see what Ped says before both of you hang draw and quarter him. TBH from the outset with his sales thread and now here, both Livinloud and Scumbag have been very aggressive in their stance toward Daawood.

Take a chill pill both of you and let the events unfold. Going off half cocked, like you did in the last thread (Dr laser) wont get us anywhere...

Good luck midnighttatoo I hope this gets resolved quickly! :beer:

Edit: Wanted to rep you Jander but it wont let me...next time then...

ped · Jun 20, 2013

Agreed.

I've been in private contact with both parties and they have been nothing but up front, honest & looking for an amicable solution.

And I believe that will be the outcome. I'm going to lock this thread now until a conclusion has been reached, or things need to be discussed.

ped · Jun 21, 2013

The package.

The diode & driver removed from the host.

With the heatshrink removed to expose the soldering.

Its hard to see from this photo, I captured it as best I could but the front, just around the window is pushed in.

Driver desoldered.

And the result.

1 dead diode.

Tried both polarities and higher voltages.. diode is open circuit.

So, over to you guys to see how you want to handle it.
