EVER KILLED A DIODE?? see this..

Hah, I've got a bunch of three-prong cables! Sounds like I've got a project to work on :san:

It's a 25W iron, so I'll probably forgo the dimmer switch, but that's an interesting idea, could experimentally determine temperatures and mark them on the dial for eutectic solder or staying below damage thresholds.

Thanks for digging up that thread on TVS selection, by the way :D
 





The first thing that popped into my head after reading the few last posts...
:whistle:
 
Perhaps Mr Benner(afaik there is no 'Mr Pangolin') appeared to be just another spammer selling his wares but I doubt there are any at either forum who know as much or more about ESD as Bill.

Making fun of him does not make you righjt or smarter IMHO.

Being that there are some 'crossovers' between handheld ethausists and DIY projector builders posting info about the Lasorb seeems approperate to me.. just my 2 cents.
as far as this

'absolutly cannot afford failure' what you may not be taking into consideration is that this is not about the cost to replace a failed diode but rather the effect a failure has mid-show-- If you contract to do a show using X number of projectirs there exisits the possiblity that you may not get paid due to the failure of a diode/projector. For this reason show operators sometimes must keep back-up Pjs on hand to use in the unfortunate event of failure.

So the Lasorb is more than just esd protection. It was not designed for use in handhelds so unless you are a cross-over just please realize his thread about Lasorbs was not meant for you.

For lack of $8 esd protection thousands of $$ are at stake when doing a contracted lasershow.

I would not consider building a 445 or 638 labby w/o a Lasorb and making one from scratch may be cheaper... but only if you think your labor/time has no value.

My goal in this post is not to rekindle any argument about Mr Benner, lasorbs or any other form of ESD porotection you may wish to use or not.

thanks for reading this post.

I call him Mr. Pangolin because I dont know him well enough to call him Bill.

I dont think people were making fun of him on that thread. What I found funny was how he skirted some genuine questions, and commented on some of the posts from lesser knowledgeable members. And only then to defend his products. I mean we're not talking the secret to making plutonium here, LOL. He's the one who stepped into the conversation, the original post was not about his product. He should of just joined the conversation as a regular member, not a sales man. He would have gotten more respect.
 
Ok --n/p you must admit that you would never want to have a collection like he one in the photo from Bill at his Lasorb site- & btw thay make several versions of Lasorbs and I can only think that one would not do the same protection for all diodes.

Not meaning any debate but Bill has only posted in three threads- one started Markusunread, one by me and the other by 'mark' who thanked Bill for his post-- so where is he posting in an offensive manner??
He only gets personal when pushed and he cannot help about the opinions of others. Lasershow folks have no reason to love handhelds and many reasons to dislike thier existance. Anyone who gets involved in DIY PJs or doing shows sooner or later find valid reasons to not find them to be such a good thing.
Lasers to them are tools not toys.
Bill will never be 'just' another lpf member- and if he came on as such , some would be critizing him for pretending to not be involved in the industry.

In his only second post ever at LPF he writes...
quote:
In any event, for hobbyists on this forum, it might not be all that important. If you folks don't see the value, then you don't see the value, and that's that. But for people who want to protect laser diodes that are significantly more expensive, or who absolutely can not tolerate a failure, LASORB is an absolute bargain!
Best regards,
William Benner

Man!!! he is really shoving this down our collective throats (sarcasm)


I have met Bill at SELEM, heard his presentation and you will never meet a more friendly, sincere and helpful guy. Pangolin is his 'baby' and they are the leaders in lasershow SW. And since there is practically no market for Lasorbs at LPF IMO his only motive in posting was to be helpful by sharing the vast amount of info and testing Pangolin has in regards to ESD-- by defination 'Spamming' as a critizisim is invalid as LPF is not a market for Lasorbs.

and this photo from the Lasorb site is proof that they know how to kill a lot of diodes lol..(so others may not do the same)
If you want see the paragraph titled.. 'Why we are confident in our results"

its the third one down here:

http://www.lasorb.com/02_we-destroyed-hundreds.htm

So you can see that the cost of Lasorbs reflects many expensive pieces of equipment and years of testing and at considerable cost to develope Lasorbs. Its too easy to say that a few dollars worth of veristors etc makes the Lasorb some kind of over-priced bad deal.

again just hak's dos centavos.

Am I the only one who doesn't find that diode graveyard to be that scary?

Nobody said those were $50 BLUES, or $200 single-mode REDs. I destroyed hundreds of diodes just sorting through the 9mm IRs that I bought in that infamous hureur auction. That set me back... like $50 bucks ;) Heck, you can buy 100x red laser diodes on eBay for about $70 ?

At any rate, the point I actually jumped back into this thread to make, is that insurance is not strictly a logic-based decision. People generally have trouble accurately evaluating the likelihood (and the potential negative impact) of bad things happening. Spending money on "protection schemes" is often an emotional decision.

If you tell someone that one approach is better at protecting an investment than another approach, they'll often spend more for the supposedly better approach, even if the actual incremental benefit is highly theoretical or practically irrelevant. Things like this are often emotional rather than logical decisions. Projector guys think the Lasorb works, and it probably does. They'll keep spending their $8 on it, even if something else works too, and would cost less, because it makes them feel safe. They're paying for that emotional security.

And that's just fine.

Try to remember where you started Len.

http://laserpointerforums.com/f37/lpf-members-sorry-my-rudeness-42825.html

And where you are now.

http://laserpointerforums.com/f55/jetlasers-gb-7-now-ongoing-lqqk-70494.html

So you're saying these kind of people dont like people like you. So if they dont like people like you, why do you defend them? I dont get it.

Anyway, its a DIY forum, not matter if its pointers, or PJs. So if we can find a cheaper way to produce a product, it will always be discussed in length. The "Company" section is where we discuss company products, and advancements.

+1 (not that it matters - you've got so much - EDIT: looks like I can't right now anyway)

A lot of members on LPF seem to endorse this culture of "bashing those who seek to find lower cost alternatives". It's like people are trying to convince the world that they're "big boys", by suggesting that everything should always cost lots of money, always, forever. This notion reeks of insecurity. I can understand the sentiment that quality is important. Of course it is. But the attitude I see on LPF goes beyond a reasonable interest in "quality" and crosses into the irrational territory of a preoccupation with "expensive for expensive's sake".

It's fraking ridiculous. This is a hobby. By definition, we're all trying to experience as much as possible, on a reduced budget. That's what a hobby is about. Whether it's trying to experience flying a plane without the money for your own jet, trying to enjoy trains without a railroad, or making your own wine without a vineyard, a hobbyist is meant to improvise and to seek new ways of accomplishing more with limited resources.

It used to bug me when I'd see some forum vet tear apart a new member for trying to improvise a lower-cost approach to something. You'd see some 50-post member ask "What's better for quality on a budget, O-Like or Rayfoss?", and some jerk with 1,000 posts would say "Laserglow". As time goes by though, you learn to not let it bug you, and recognize that it's just a reflection on the personality of the member. There will always be grumpy old jerks that want to hoard experiences; curmudgeons who've been in the hobby so long that it just kills them to see someone new experience blue coherent light for the price of a DVD, when it cost them the price of a television to do the same 5 years earlier.

This IS a DIY forum, and any time there's an opportunity to "Do It Yourself", for less, that's worth exploring. That's what the community is all about.

depends just think reds have not allways been 8$ a piece you used to have to buy whole drives same with phrs etc etc depending on what and when that could be over 1k down the crapper :cryyy:
 
BTW... who is going to test and make a video of those
"Protector" PCBs connected to a Laser Diode with High
voltage ESD like Pangolin did in one of their Videos
showing how well it works...:thinking:

I know I don't have one of those ESD instruments...

@ TJ-- i read both links and see nothing there with anything to do with this ..
"So you're saying these kind of people dont like people like you. So if they dont like people like you, why do you defend them? I dont get it."

certainly you must have something other to do than be my personal PITA.


I have even defended you s few times but you make that not easy sometimes- as usual your get all blown up over an 8$ esd device- we get it-- you dont want one .need one and have never killed a diode- OKL?? let it go the stress is not good for you.

Please do try to explain I will be happy to no longer post in this thread.

you are not my dad

Nah, there have always been cheap diodes. Well, not always, but for a long time. Little 5mW reds etc have been cheap for a long time.

It doesn't matter - this isn't a competition to see how much money they can blow on diodes. My intention was just to point out that saying you've destroyed "hundreds" of diodes isn't a great convincer, when some LDs can be as cheap as LEDs.

I have some throw away IR diodes, and a 14KV Neon Sign Transformer. :whistle:

Len I dont really care about $8, or am I trying to be your dad. I dont build, so I dont have use for them. I do support the DIY aspect of the forum. I've always been behind creativity.
