IR Laser from DVD Burner

the diode used to read or write a dvd is visible, the one he is using is likely the CD diode from a combination DVD/CD drive. CD diodes are infrared, and mostly invisible. some people can see the beam but its very dim, DO NOT TRY TO VIEW THE BEAM DIRECTLY!! I would also like to point out that adding a pot in his circuit would have NO effect on the frequency of the light emitted by the diode, that is determined by the makeup of the diode crystal.

you have to be an idiot. any laser can be configed to cut and burn S**t this is a simple DIY

the laser only becomes visible red at higher frequencies,( 7-13hrz tends to be visible) the default setting on DVD burners is very low and does not burn or cut well at all as you can see he struggled, you should have placed a POT in the circuit would have made the beam "visible" and burned/cut much much better. At a high frequency/voltage ratio a DVD burner's laser can easily cut metal. Any and all lasers can be visible or invisible all depends on frequency.

Whaaaaaaaaa.

isn`t a dvd laser diode visible red?

thankyou, that is what i am trying to express, srry i any1 miss understood me, oh and go ahead n -1 my comments, I keep a tally at home, 21 as of now, you can go to my page, theres an area of my prevous comments if you people thenk in that much of a sped, its like a game 4 me rely,lol, i get joy from +1, from some1 that understands and/or agrees with me, n from -1's for the above reaason, HAVE A NICE DAY TO ALL WHOM READ THIS /:~)

The laser beam is the radiation, thats what they are talking about. So if you don't point the laser at yourself then you won't have a problem. There is no other radiation emitted, look up lasing on wikipedia if you don't believe me.

led reduses radation, if you test a drive caseing(wich i have done)its about 70% lead

stfu, yes, if you use the wrong laser, over power it etc, you will get radation xion! thats why theres lables on everything, dont poing in your eye dont expose to shin, go look at dells support page

Never heard CD cases having lots of lead in them. The warning about laser radiation on a CD player is just warning you about the laser, because that is what is radiating.

the dumbasses are the ones who defend people who are factualy incorect and missleading to other dumbasses, therefore you, and not I, are the dumbass.

iq tests... and irony detecting tests... dumbass!

"this video is just a photoshop fake" since when did adobe add video editing to PHOTO-shop? i think youtube needs to start screening members with i-q tests.

are you kidding? as a tech i had to open countless cd drives and i dont have cancer....
yet.

yes! now I'm going to go rip apart my computer just to get the laser!
