Yep, you are right that one is IR and the other is the red burner. Telling them appart could be a little tricky. Are they both closed can or is one open can? If you post the model number and speeds of the drive we would have more to go off of. Pictures of the diodes might help too.

You would probably find a low power red diode and an IR diode. Nothing capable of burning anything.

@Diachi, Hmmmm, wish I did. All I have to work with is self built DDL driver circuits and a DMM. @daguin,  thanks for the info. It looks though like I would need a laser power meter to find the knee. Is there a different way to measure it?

Cool. Thanks for your help. I will probably just have to do some experimenting and see what happens. Guess if I blow it out it isn't too big a loss considering it is a freebie. If I get it working and it doesn't burn out in the first hour or so I will post my findings incase anyone else decides...

Hmmmmmm....... Thanks for the info. I may have to experiment. I will give it a little longer though and see if anyone has experimented with 8x before. Wonder if 100mA would be a good starting point.

Cool! Any idea what current and voltage I should drive it at?

Here are the speeds. 8X ± DVD Write and Read 4X ± DVD Rewrite 2.4X +R9 DL Write 24X CD Write and Read 16X CD Rewrite I am hoping to make a deicent powered pointer out of this. It doesn't really matter if it is capable of burning anything or not. Any idea what this could put out as far as mW?

A friends old 8x DVD-RW drive kicked the bucket and they were nice enough to let me have it. I am wondering what would be a safe current to drive an 8x LD at. Any suggestions? Also, would voltage requirements still be around 2.5 to 3 volts?

Cool! Thanks for the link. That helps alot. [smiley=thumbsup.gif]

I agree completely. The difference between soldering with a good Weller station like the one above and a cheapie Radio Shack iron is night and day. You will have much better success and a shorter learning curve if you get a good iron. If you plan on doing alot of soldering/laser building it is...

I am sure this has probably been covered somewhere here but I have not been able to find it. I am wondering what the major differences there are (if any) between the Sure and Aixiz laser modules. It appears that most use the Aixiz so I am wondering what benefits it has over the Sure. The...

I am guessing you mean 200mA. Just adjust your pot until you have 200mA of output using your test load. With two 10 ohm resistors the max output on your driver will be about 250mA. If you want to set the max to 200mA there is a formula on the first few pages of this thread that you can use to...

Here's the chart. http://www.laserpointerforums.com/forums/YaBB.pl?num=1210649510

Looks like it is a 16x diode based on the specs for that drive. I would guess its output would be similar to the Sony 16x diodes that many use here. There is a chart somewhere here that should give you an idea.

I was actually curious myself about using laser printer diodes. Problem is that all the info I found indicated that most if not all laser printers use an IR diode. This means you will not actually get a visible beam out of the diode. Just a dim red glow from the LED part. If you connect it to a...

Sounds interesting. Do you know what speed the burners were? 8x, 16x, 20x? 350mA is alot! You should be lighting matches with that I would think. I have an 18x open can at 220mA and it lights matches instantaneously if I color them black. I can also easily burn through electricians tape and...

Re: Im looking for one of the best diodes i can ge If you have a good sharp pair of wire nippers you should be able to use them to cut the heatsink. That is what I used harvesting the diode from a LiteOn drive. The nippers will actually expand the heatsink away from the diode as you cut it...

The DVD Burner diodes will be much brigher than the CD diodes. Actually the CD diodes are most likely IR which means you won't be able to see the laser light. Don't look into them! At 200mA you will most likely blow out the CD diodes and without a module to act as a heatsink you could burn out...

Re: Im looking for one of the best diodes i can ge I think I recall reading here somewhere that the 22x long open can diodes can push that kind of power.

I had the same problem when I built my DDL driver. Turns out I had misswired the pot and the regulator somehow. It took several reviews of the diagram before I finaly figured it out. Just keep lookin it over and I am sure you will find the problem. ;)
