Hic. I've killed 5 diode already. 4 are from broken DVDRW that I have and 1 From my PC :cryyy::cryyy::cryyy: 4 of them I shock it so that is why it die, but this 5th one didnt die, its just dim, really dim. I'm out of DIODE now. SOOOO SAD.
I've change the Pot to 100ohm and it seem to be stronger than before. I use 5ohms resistor and it was able to burn but it take about 10sec to start burning so I change to 4.7ohms and it take longer to burn. After that I switch back to 5ohms the laser was really dim and now it wont goes any...
I've followed the AI and make my own driver for it but it doesn't seem to have enough power to burn through anything.
I follow this AI:

it doesn't matter if I use one 10ohm resistor or two, it still won't burn through...
