Oh Okay, did i take a risk running at 125mah? it was only on for about 10-15 seconds at most.. I was going to ask about sand paper, guess that answers my question. Do you have a recommened grit? And about the possible loose glass lense inside the LD's can, how is that going to affect things?

to answer your question, yes it was solder and it seepted down into the side of the diode too it was a REAL mess so in the end i just broke off the old housing with pliers, which cuased me to put 2 little 'bends' in the can housing part of the diode itself, which i think cuased the little peice...

** update I dont think i broke it, but i do think the little lense inside is loose, i got it all out of the housing, and hooked it up again for another quick test, it does still light up so it appears to be working still to some degree. the problem now is that there is solder residue around...

okay i think i broke it, i tried to break the peice off with 2 pliers and i did break it out but now i hear it rattle when i shake it, i tink the little glass lense peice inside there is loose now...

Is that safe? is the diode housing pretty strong? I'm trying not to kill this poor thing before i get it out.. why they felt they need pea sized drops of solder to hold this thing in at 4 places is beyond me! so dont try to snap anything in half with 2 pliers then?

Sure! here's a few pics... Please never mind how bad the soldering looks i started trying to cut through it with a knife after a while as i do not own a dremel at this time.. i also tried to peel off the 'cuircuit' tape that was on the diode, but it didnt like that s much so i left half of it...

Yeah I think I've got the calculations correct. I dont want to push it to 250, (unless it needs that to pop a balloon) I was hoping to keep it at about 200mah and ideally would use a 6 ohm (i bought a 6.2 and 6.1 while at the electronics store) to hit that number. my biggest problem as I say...

Thanks guys! I ran a test using the diode, it worked! i picked the right one first try.. I used a single 10ohm to get it down to 125ohm instead of going with 250 as i've read a few posts here that says 16x diodes should probably be around 200 and i don wana push it.. I did not have it in...

Hey guys i'm still fairly new here, i just got my parts for my 317T DDL driver, and after frustratingly trying to build it for 2 days I think i'm ready to test my two DL's. real quick, why it was frustrating was apparently the person who sent me the Vairable resistor sent me the value of 100k...

Just to make sure i'm not confused, the pic you reposted is actually more 'focused' on the housing that the diode was pointed into, the diode itself is the blurry thing out of focus thats closer to the camera, so is it correct insaying that the housing it was focused into, being more blue, makes...

And at that, what would be a good guess for the specifics of powering the diode? 125ma?

I actually took the whole drive apart, its DEFINATELy at 16x burner, just cant remember if it was CD or DVD but i think it was DVD burner.. I tossed out the extra parts, cuz I totally forgot i might need to reference the info. So even tho in that picture of mine the middle one looks more...

Ahh so does the dvd burner diode also burn the cd's? or does that mean the cd diode is a burner too and i could make 2 lasers? I only see the 2 diodes with 3 pins, where's the 4 pin one? not that i need the 4 pin though... I cant tell that either is any darker, though looking inside the housing...

You're right i dont have that :) i'm thinking i might just hit the electronics store tomorrow and get the peices for the lm317 and see if there's any other way i can rig up some of my 1.2 rechargable AA's to be the powersource for a small test.. Btw anyone have a guess which one of these is...

Thanks guys, It wasn't so much that i didnt want to spend the money on them, but if my diode is already toasted (no real reason to think it is but i like to be sure) Then i'd be out the diode and 25 bucks worth of parts that might not get used, AS this was kind of a first try experiment and...

But i'll need to get some of the 3.7v batteries for this right? cuz the lm317 requires 7.4 volts or close to work? Thats why i was hoping to be able to just test the diode before i spend all that money (gonna cost me at least 20-25 ish to get the parts and batteries and charger).

New Here, about to start building my first basic laser (not sure what its MW power will be it came out of a 16x cd writer). I know i'm going to be told "Never run a laser without the driver" but is there a way i can use like maybe a single 1.2 volt battery and a couple resistors on a bread...
