The blind leading the blind...

No offence intended, but your posts make my eyes cross

A lot of people "get" into lasers from seeing Youtube videos.
It's only when they come here or another forum that they realize how misinformed they were.
Take the video's of hooking a laser diode directly to a battery.
Sure it will work.... for about 2 minutes, if you are lucky!
Or video's of people shining their 200 mW green around without safety glasses on.
I even seen one where the guy's beam was reflecting off of a glass object and hitting very near his face. Stupid!!
And or course the famous lighting a cigarette with a 6X, without glasses on, while holding it in his mouth.
People do not realize how dangerous lasers are, I guess.
And, don't get me started on the misinformation out there from e-bay sellers. Do they pull the specs. and information, out of their As$???

Heh, the guy likes colors! So what?
We all do, otherwise we would not be here

Nice work on coloring your posts, Mechanic!
I personally am too lazy to do it :crackup:

Nothing wrong with colour, but its like reading an elaborate sig.
TBH, if im skimming through a thread, I cant tell where his post ends and his sig begins :thinking:

Maybe add at the bottom

Here in Croatia everything about lasers is pretty much 20 years behind the rest of the world.

My friend who was a member here also, one went to largest electronic component store in Cro (pretty famous one, they basically have every component you can think of needing , not closely related to lasers OFC), and saw a <5mW red laser module (something like aixiz, only it was not chromed and it was not focusable I think).

It retailed for $35 or something (that was a year ago or something, mind you!).
My friend said to the guy behind the counter: Dude you for serious? I can buy two 300mW LOC diodes for that!

The guy said: Well yeah but they emit a lot of IR which is harmful.

*facepalm*

EDIT: Oh, sorry for going off topic here, I also witnessed a lot of facepalming comments on youtube.
Some also claiming red lasers emit IR, that videos of lasers doing some burning are complete fake,
And my favs: (not quoted , something alike that, not seen only once)
" I tried kipkays hack, after I connected the diode to 9V batt to test it, it is a very weak diode and does not burn"
"It's fake, if it was not fake, the diode would melt the DVD in the drive"
"The diodes are very weak, they do not burn, they only emit very faint light"
And variations are endless ...

I second the facepalm

my favorite youtube comments are the "this is fake! you'd have to be a 5 year old retard to believe you could actually burn something with a laser, go watch star trek or something!" ...I get the insatiable urge to just come over to that person's house and punch them (maybe a nice laser burn on the arm with a 12X BluRay would get the point across too)

however much to our dismay, the hobby isn't going to last very long. it's only a matter of time before some maniac terrorist gets a ClassIV IR laser and walks around a mall blinding people by the numbers... *banhammer* heck it could be as simple as somebody misusing a 100mW Greenie in a classroom!

peace & thanks

A lot of people are consuming illegal drugs which are unbelivably easy to get (some of folks I know are potheads...), despite the fact that they are banned.

They can ban the crap out the lasers, but it sure ain't stopping us from building them!
They can have my lasers when they hammer them out of my dead hands.

 

[Moebius]

Even if pot was harder to get, potheads would get it.
Same goes for lasers.
But i'm not too worried about the psycho nerd who goes to the mall with a Hercules.
Unless it's you cmak :gun:
I'm stockpiling lasers.

I'm stockpiling lasers.

Me too.

They ain't gettin no lasers from me.
Even if they do, I make sure they do not get all of em.

:crackup: ^lets hope that it does NOT come to that!

Oh god.. No wonder people go around blinding themselves with lasers, thinking it's safe. Basic laser safety/info should be taught in science class in schools, lasers are becoming more and more usual in daily life.

Well, there are a lot of retards that will use this information to blind the rest of the normal people, like the people of my school. Last day I was alone in my class and the "people" on the other building were shining a crappy <1mW red laser into the blackboard of my class. I turned to look at them and they shined it at my eyes, (well, a 10" diameter point into my eyes is nothing, but...) so imagine what will occur if they use an ($10) 10mW green.

As i said, kipkay is stupid or i think he just does this things on youtube and in real life he uses drivers... he is very stupid if he doesnt.

Ya mean like this??

YouTube - KTP Yag Laser

This guy is just retarded....

True that!
