Question about harvesting

[steveclv]

What projectors are the best for harvesting diodes?

I assume the higher the lumens, the more diodes are used. So a 3000 lumen has more diodes than a 1500 lumen?

Do they have R G and B diodes in equal numbers?

Are all LD projectors DLP and are all DLP projectros equipped with LDs?

Trying to find out some background info on this. Thanks!

Definitely not all DLP projectors are laser projectors.

DLP Projectors are split into 3 categories:
1) Lamp
2) LED
3) Laser

You need a laser projector specifically to harvest laser diodes.

*edit*: and no they don't have equal red and blue diodes. On top of that, they don't use green diodes as far as I know, since the 510nm just came out like few months ago.

 

[steveclv]

How does the wattage of the LED 'lamp' equate to the number of diodes? Can that be determined in advance or is it a case of 'suck it and see'

For example HD protable LED 1080P projector HDMI PC Wii PS2/3 Xbox | eBay says it has a 60W LED lamp - 60 1W diodes?

Do all LED projectors have harvestable diodes?

Or did I completely misunderstand - LEDs are not necessarily Laser LEDs right?

Phew! I'll get there in the end

So this was how knowledgeable you were about lasers when you were arguing with me about laser safety in this thread from page 2 to 3. :tsk:

You should be thankful I'm still here helping ya out when most users will just read this thread, facepalm, and be too frustrated to answer you.

Anyway... a laser diode is a specific laser diode. A LED is a light-emitting diode, and is NOT a laser diode.

LED projectors have harvest-able diodes, but not harvest-able laser diodes.

Again, you need a LASER projector to harvest LASER diodes. Nothing else. Not lamps, not leds, but maybe hybrids.

Wow, it's a good job that I am a mature, polite individual.

I know very little about the current laser, LED, Hybrid projectors. I know very little about harvesting laser diodes from DVD burners etc - but I am willing to learn.

I do know a lot about safety systems, ISO9000, ANSI standards etc because I spent 20 years working in Defense and I stand by everything that I wrote in the other thread.

I'm worried that you know a lot about harvesting diodes, building and selling high power lasers and a lot less about safety and safety procedures. Have you ever considered your legal liabilities when selling a high powered laser and what happens if someone gets blinded by it? Do you ask them to sign a Release of Liability? Hence my comments in the other thread.

If you want to be a smart alec with me then let's just stay away from each other in these threads - I'm sure others will be willing to answer my questions because I want to learn and am not closed minded.

You constantly seem to assume I have no concern for safety when you know nothing about me.

Also, if others were willing to answer your questions, they would already have.. after 115 views. Just saying

Then again, I'm the smart alec right? So I'm probably wrong.

It's good that you want to learn and all, and I'm here to help you... but it'll be nice if you could be that "polite" person you say you are, rather than pull assumptions out of your ass and indirectly attack me as well as all the builders on this forum.

All I know about you is what you post on these forums - from that I draw my conclusions.

Remember, you started the 'attack' on the other thread because you could not accept that my arguments about lasers being 'dangerous' were warranted.

And I just read all of steveclv's comments and am not impressed with his level of analysis.

1) You talk about guns and lasers as if they're on par in terms of danger when they're clearly not. You compare someone getting shot in the leg to a laser hitting the eye then claim you can recover from the leg wound but not a burnt retina. Well can you compare apples to apples please? A gunshot to the eye means instant death. A laser beam hitting your leg, or any other part of your body than your 2cm wide eyes, is harmless.

2) You talk about lasers as if all we do is "play" with them. You miss out entirely the education aspect of our hobby.

3) You exaggerate the availability of lasers. I don't even know a single person out of my 660+ FB friends who have lasers, discounting the few close friends of mine who I have built for. On the other hand, I know about 10 people who have either illegally bought a gun or legally has one.

4) You act as if the statistics of kids blinding themselves with lasers are alarmingly high. You then, don't realise the thousands of kids who have killed/maimed other kids with guns.

I don't understand how you're on a laser forum with your apparent phobia of lasers. If you really think hobbyist lasers are more dangerous than guns, I suggest you hide under a rock for the rest of your life.

So yes, based upon you comments and where you openly encourage people from countries that have import restrictions to buy home made lasers because they look like flashlights (and thus probably also lack the reqired safety features of a custom build host), I do question how seriously you take laser safety.

Other builders have openly refused to sell their lasers to countries where they are banned and I applaud them for their stance.

Are you illiterate? Lasers ARE dangerous. They are NOT as dangerous as guns. And no I was not attacking you, it's true that if you seriously think lasers are as dangerous as guns, you NEED to hide under a rock. It's the only way to protect fully protect yourself from the thousands of other things that would also be equated as dangerous as guns according to your scale of danger.

With every post you are clearly displaying your ABSOLUTE ignorance to this entire hobby, yet you speak as if you know all there is to laser safety. Listen to this very carefully... According to your evaluation, EVERY SINGLE builder on here should not be selling lasers. NO laser in the BST section currently satisfies FDA qualifications for a "safe" laser.

You are claiming that I encourage people from countries that have import restrictions to buy hand built lasers (I am assuming you are talking about Canada). Yet, YOU FAIL to understand that the USA has the SAME import restrictions and the SAME builders you "applaud" are breaking the exact same rules. The only reason YOU think I'm breaking the rules is because the Canadian restrictions are NEW and you being a 7-day member of this forum think you know everything because you just read a couple of threads about this... You will not be liked on here if you continue with your pride and ignorance. You also fail to understand that I limit myself to sell to Americans and help out my fellow Canucks who have to deal with this terrible restriction. Why are you caring so much about MY country when EVERY other seller is breaking YOUR country's laws. ughhhh you're reallying getting to my nerves. *sigh*.

Regardless of all this trashing you're doing to me, I'm still here educating you and still wish to continue to help you out. I hope you drop your attitude, swallow your pride and take back what you said about me, because I'm willing to drop this behind us and start a fresh.

So you never offered to sell a laser to Germany as a flashlight so that it wouldn't be confiscated then?

You think that it's perfectly safe to wave a high powered laser around the sky without needing goggles?

You think that it's OK to aim a laser at your skin? In fact you even burned yourself on your first build right?

You are ok with selling to anyone as long as they photograph a set of goggles - no consideration to their age (no ID required).

A 50mW laser is perfectly safe and will not burn.

I realize that you are still at college and have not yet learned some of the life lessons but if you took the time and used your expensive education to try and understand reasoned debate then you might actually learn something. I and others gave you chapter and verse on why lasers ARE more dangerous than guns and yet you seem to be completely incapable of understanding another person's perspective. I put it down to immaturity and eventually I am sure you will get it. Until that happens, I'll stay out of your way, and you stay out of mine.

you are being very impolite

lasers more dangerous than guns? ROFLMAO:crackup: Lets see you can take a 1W laser anywhere in the body and NOT die.... Thats not true for a gun. Even the weakest guns can kill you with one bullet. Not so for the strongest of lasers we make around here. Sorry OP, lasers are FAR less dangerous than guns. Yes maybe in the future when we have light sabers and that kind of crazy hand held lasers, but not now. You seem to assume a lot about him, yet he never said anything you are claiming.

you are comparing knives to guns here....

Well seems like you're still stuck with your ignorance and pride and on top of all that, have decided to become extremely rude.

For readers out there:

So you never offered to sell a laser to Germany as a flashlight so that it wouldn't be confiscated then?

--not sure where you got this. But sure I will sell flashlight & laser parts to Germany.

You think that it's perfectly safe to wave a high powered laser around the sky without needing goggles?

--yes, it is safe to use a high-powered laser and point it at the sky w/o goggles. There is no chance of the laser bouncing and hitting you back. DO MORE READING.

You think that it's OK to aim a laser at your skin? In fact you even burned yourself on your first build right?

--I never said it was OK to aim a laser at skin. Are you an idiot? It was an ACCIDENT, you think I wanted to burn my skin? Are you fking dumb? You're really pissing me off now. Direct quote from my thread:

"It also instantly burns your skin, which I found out painfully the first time I adjusted the focus."

I ADJUSTED THE FOCUS and burnt my finger ON ACCIDENT. If i wanted to burn myself on purpose WHY would I coincidentally burn myself while trying to adjust the focus. You are SO CUNNING and SLY with your FALSE accusations.

You are ok with selling to anyone as long as they photograph a set of goggles - no consideration to their age (no ID required).

--Not true. I always evaluate the buyer before deciding to sell to him/her. And mr. know it all, I am not required to ask for ID.

A 50mW laser is perfectly safe and will not burn.

--I don't know where you got that I said it's "perfectly safe" <-- as i would never say this for a 50mW. But burning ability depends on many factors including wavelength and focus ability.

+ I like how you TOTALLY ignored my previous points above. Now get yourself a f**kin education because you're an outright ignorant idiot and a total douche bag. I NEVER SWEAR and NEVER get this mad. WHO was the one who was patient enough to answer your questions when nobody else cared to help? Who was the one who after "attacking" you, wished you the best and continued to help you? You are SO UNGRATEFUL. I even offered to drop this behind us and start afresh but you have absolutely pushed me to the edge with your retarded accusations. Now GTFO of this forum.

now you are implying ryan is a dumb@ss thats like shooting yourself and claiming its safe to point it at yourself.:tsk:
