is that a IR diode or a Red diode? or what?

[howry]

i took my dvd rom apart, just for checking what kind of things are inside. dont know whats inside!
help please

What kind of drive?

 

[Liberty1992]

if its a burner its red, if its a reader I'm pretty sure its IR

 

[howry]

i believe that its a reader, what can you do with that? is it useless?
and what kind of stuff you can make from IR diode?

 

[Liberty1992]

as far as i know (I'm just goin off what i see around the forum) you cant really do anything with a reader, it isn't powerful enough to burn anything so your more likely going to hurt yourself, if you correctly set it up, since you cant see/barely see the light even though its quite powerful. if you happen to have a CD burner lying around that has an IR diode too, but at least that one has the capability to burn things, given that you set it up right. BUT****** before you mess around with IR AT ALL you need to get IR goggles or you can severely damage your eye sight or blind yourself, and you wont even know it

Actually red is for DVD and IR for CD.The difference between burner and reader is high power versus low power.


I see 2 diodes in your picture, one is probably IR and the other one is red.Powers depending on what kind of drive you have there.No way to tell which is which from the picture.Just pull them both out.If the IR is a burner diode it might be windowless.

you can severely damage your eye sight or blind yourself, and you wont even know it

I think you'd notice if you stopped seeing all of a sudden :

we can only hope, lol. and ok red is for DVD readers too, see i didn't know that, now i do. well hey! that means i have like 5 red diodes lying around now, lol

and from what I've seen from taking many, many, many combo drives apart, the diode furthest to the outside is normally the CD and the inside is DVD, normally, idk for sure

You won't get anything good out of a DVD reader. The IR and red diodes are low power.

Not true You get the good experience of building a laser! The diode is the exact same as far as DVD diodes go. So the only visual difference between a reader and a writer diode will be the output power (unless the writer is an open can of course). ANYWAY, these reader diodes are perfect practice. You get to build a laser, see it work, it just wont have all the power. But if you mess up it's no big deal as you're not really losing anything out of pocket

 

[Liberty1992]

i agree with Gus, try it out with the DVD reader anyways and gather the experience

Won't a 5mW diode actually need less current and would die at currents that are optimal for writer diodes? :-/

Btw, a DVD reader can still be a CD writer, and have a powerful IR diode.
Plus, you get some optics.

Dunno.
