I already have accidently fried two perfectly good SLD1239JL-54 16x diodes by making careless mistakes in my homemade Daedal DDL driver circuit. In order to prevent mistakes on my third attempt, I want to know if there are such things as cheap diodes with similar electrical tolerance thresholds...

Can anyone tell me the type of goggles I should use when working with the SLD1239JL-54 at above 200 mA?

Right now I am currently using a daedal DDL driver for my SLD1239JL-54 16x DVD diode. I designed my driver so I could measure amperage while I run the laser diode. I did this by soldering the leads to a multimeter into the circuit like in this photo I currently have the driver set to 250...

I don't want to spend all that money on expensive laser goggles but I am worried about safety. I would like to know if a shape 13 welding lens would protect against lasers emitted by a SLD1239JL-54 laser diode at over 200 mW? Without safety goggles would simply avoiding direct eye exposure be...

1st question- I remember reading a blog saying that a diode has to be fitted in an axis module "PROPERLY". Is there a certain way you have to put a SLD1239JL-54 16x diode inside the axis module to burn or do you just snap it in? 2nd question- After being told that a SLD1239JL-54 diode needs a...

Is there anyone who would like to sell me a working SLD1239JL-54 16x DVD burning laser diode? If so feel free to reply.

I finished attaching the SLD1239JL-54 16x laser to my driver and I adjusted it to 128 milliamps. The laser is not burning stuff but is making a nice bright red circle. Is 128 milliamps not enough to burn stuff with? Do I  need to get the 3 or 4 ohm resister instead? Also, what type of heat sink...

Right now I just finished soldering a Daedal DDL driver (like the one in this picture in the first reply at this hyper-link http://www.laserpointerforums.com/forums/YaBB.pl?num=1227655714) and I want to know if it is ready to hold a red SLD1239JL-54 16x DVD burning laser diode? I did make a few...

Can anyone give me the schematics for a driver that can accomodate a red SLD1239JL-54 16x DVD burning laser diode? Thanks.

Right now I am trying to contruct a burning laser flashlite like the one in this video (Ill post the video later once I get 10 posts) However instead of harvesting a 16x diode from a Sony LG, instead I got a 20x from a Samsung DVD Writer Model SH-202. At first the diode did not burn, however I...

Who are you voting for.

Does kipkays laser flashlite hack really work?

Whats your favorite video on youtube?

Anyone have any good jokes?

Is it legal to possess a laser that burns stuff?
