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?

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 wondering if running a DVD burner diode at the lowest possible current required to lase would have any detrimental effects on the diode. What I am thinking about doing is using a large 100 ohm pot in my build that would allow for an external knob to adjust the laser's output. I would of...

I have successfully built my first DIY laser! Blew the first diode (a little 8x). Second diode is an 18x open-can and it is so far working great at 220mA. Probably could go higher on the current but I want this one to last at least until I can get another diode or two. ;D I have a question for...

Well, I built the test load circuit for the DDL driver using 4 IN4001 diodes and a 1 ohm resistor. When I test the voltage with my DMM I am getting about 5.6 volts. When I try to measure the mV across the resistor I don't get a reading at all. Any ideas what I am doing wrong? I have rechecked...

I just got my Sure Module today and would like to play with it as is before I use it for my burner diode. Can someone please tell me what the correct input voltage and current are for the sure module? I have searched and was not able to find any info on it. Thanks

Okay, I built the LM317 based driver which I found on these forums. I harvested my diode from a spare HP Burner and hooked it up to the driver. The diode lit up very bright and I only ran it for about a second or two since I don't have my module yet. Being a noob at this I pushed it of course...
