Ok so I finally decided to take apart my dvd burner. I did all the details to make a burning laser pointer. I am running the LD from Daedal's circuit with an input voltage from a 9 volt battery. Now, not wanting to blow my precious LD, I am getting a nice red dot at 130 mA. Also the LD is running at 2.72 volts. Is this too low to burn anything? Or is my focus off? I have it focused so it is a nice round bright red dot about 5 or 6 feet out in front of me on the wall. If anyone could help me I would appreciate it. I dont want to push the mA too far and ruin the only LD I have.
