hey just wondered i have a few of them old portable CD players as a kid we seemed to reck a lot nd they werent expensive so i have a lot could u use the lazers outa them
No it wouldn't.. It wouldn't work for anything, other than damaging your iris, a bit at a time. Those are IR, and really low power at that! Not usefull!
Theyre not all infrared. The one from my cd player is visible. Besides, infrared lasers can burn through things too. And like I said it would still do a bit, just much slower, and much thinner things.
How the the hell would you cut something with a diode with a MAX output of 5 mW? What your saying is "hey i'll use this cool red laser i just got bought in the dollar store to cut black tape!" omg..
Fine, i'm sorry i'm not from the states, so i have never seen the lasers in the dollar store.. Regular red laser pointers are 5mW. Cd lasers have 5mW MAX output, you can not cut anything with them.
iR is REALLY POWERFUL
it's also cheaper to maufacture
it's really dangerous, if it accidently got shone in your eye you could be blind. With IR you have no blink reflexes.
Actually red light is on the weaker end of the spectrum.
If you want high power, go for blue or violet. Those have the most energy. IR is only dangerous because you can't see it.
I just got the diode out and hooked it up to 2 AA batteries at first it was nice and bright but i dont know if i shorted it or something because now it is weaker than my cheepo $1.50 laser pointer. I had a short glimpse of its potential!! What happened did I ruin it?
Most likely yes if you don't have a driver for it it will burn out the diode I did it to mine on accedent so now it will never be as strong as it was before sorry
Is anyone making one? I am! Only thing I need is a freaking colliminating lens, and I'm not going to shell out money.. I'm testing alot of wierd lenses, I've got laying around, but no luck yet.. Any suggestions?
What is shorting the diode?
Could a magnifying glass make it more intense?
If you make a sliding grid to mount this on, you could trace a line drawn styrofoam/cardboard(maybe) to make the cutter mentioned earlier more effective
no, the "peep hole" idea dosent reflect the beam into 1 spot it just blocks out the other light so the light is still dim.......... its not concentrated into 1 spot
no it most likely wont work. when you magnify the sun like that, your actually just condensing a wide beam. lasers are already a thin, powerful beam so it wouldnt do any good.
hi we just got a compact disc cd/rw drive from a computer.. we took it apart and here are a couple of the parts that we think we need to use for the laser could u tell us what they are?
thnx Ibo
Heya! Impact2us start with the parts... im nooby at instructables so i dont no waht picture............................. but wanted to tell you that you shouldnt use a cd burner cus they are ir burners(infa-red) so u wont be able to see them! and a much more unsafe.I recomend that u go get a dvd burner from sum garage sale or sumthin or check the computers for a dvd writer -should say on them wether they are or not

it wouldn't be as powerful, though it would probably still work.

First of all...calm down. Who said anything about the dollar store? Dollar store lasers are 1mw. A laser used to read cds is more powerful.

You can if you focus it right

fyi, i just tried a cd laser out, straight from the player. I held a battery to the leads, and put it near a plastic bag...smoked instantly.

Yeah your laser got smoked..

Is that why the bag melted too?

It was the whole aparatus, so I'd assume there was already a lens.

I recommend to buy a DVD burner for cheap and use that laser

no u put toooooo much power into the diode at 1 time......with a module there is a steady flow
Reply 13 years ago
Either that, or static killed it. It's dead..
Reply 13 years ago
ya thats a good possibility because i never shorted the diode to prevent static damage. I guess I learned my lesson! thanx for the info

you can use the dvd writer lens themselves, but have a good luck focusing one (it can be done, but is a bit hard)
Reply 10 years ago
buy a laser module with a focusable lens round 5-15 us buks
Reply 13 years ago
Best I've Googles was this:
colliminating lens
See the little picture, and then get some lenses like that, out of the ones you have.

Also, would a peep hole work for the lens?
Reply 13 years ago
No. You need a colliminating lense, not a peep hole..
Reply 13 years ago
A colliminating lens takes all the light, and focus's it into a a small beam of light. A peep hole does the same thing..so why wouldn't it work?
Reply 10 years ago
no, the "peep hole" idea dosent reflect the beam into 1 spot it just blocks out the other light so the light is still dim.......... its not concentrated into 1 spot
Reply 13 years ago
Just try it then if you don't believe me. I've tried, i dosen't work..
Reply 13 years ago
You need to short the diode before you use it, or it will most likely be killed by static. No. No.
Reply 13 years ago
But I asked what is shorting the diode. Not why.
If it works with the sun, why not a laser?
And the last bit wasn't a question...it would work.
Reply 13 years ago
Why would you do it then? It's plain supid! It's CNC!
Reply 13 years ago
All you do is shorting the leads..
Reply 13 years ago
could you explain a little further?

no it most likely wont work. when you magnify the sun like that, your actually just condensing a wide beam. lasers are already a thin, powerful beam so it wouldnt do any good.

You connect the leads, with eachother.

After a few failed attempts, i ended up buying a laser from http://www.dragonlasers.com. One of the lower powered ones.
My advice to any one using the diode from a cd drive, be very careful with the input power or you'll fry the diode.
