Well my friend finally got me a DVD drive to attampt at making a laser. I stripped the the housing off of the block (pic below) and have no idea where to go from there.

Also I've heard about people blowing diodes... what need I do to prevent that?

Any pics that show that I should be looking for in this thing would be awesome.

i believe antistatic protection is one of the big safeties you need to not fry the diode.

Rasel,
It might help if you posted the make and model number of the drive.

;D Yes you do. But it should be a closed can diode so cutting it out of the heatsink should not be that hard. As far as ESD, you do need to be careful, but I don't think I have killed one diode yet because of it. Even while I was harvesting my blu-ray diode, I forgot to put my wrist strap back on a couple of times, but I was also had everything on an anti static mat. Good luck.. :D

OK well I have no idea how to prevent static build-up other than not dragging my socks on the carpet.

buy an antistatic wrist strap, connect it to something grounded, and/or buy an antistatic work surface.

i always wear a wrist strap but if you dont have one, the another way is to touch a non painted surface every once in a while like 10-20secs. :cool:

Yes that would be ok for a DVD diode. The humidity in your place makes a difference too....the higher it is the less chance for ESD. Just touch some bare metal before you touch the diode.

Antistatic wristband, JB Weld, and Arctic Silver.
JB Weld is a good alternative to solder, as there's no danger of frying the diode with heat. Arctic Silver is the best for heat transfer, and has limited adhesive qualities. The antistatic stuff is a no-brainer. If you're doing Kenom's Dorcy mod, I can go a little more in-depth. :D

I know soldering is the best, but I've fried a few too many diodes from excessive heat ;D
