Default Old DVD drive, possible salvaging of diode?

I don't know anything about building lasers, but i found this old DVD rom drive in an e-waste bin on my campus and Iím curious if the diode would be salvageable. It's a "DVD-Master 12E model SD-612" ... probably dates back to 98/2000? It's also not a burner.

Would i be able to do anything cool with it, or is it just a piece of junk to throw out?

You could mess with the optics, but in terms of the diode its not worth anything more than practicing extracting diodes.

if you have any 2-lead motors, those can be handy. Glue one of the glass mirrors from the sled onto it, voila free spiro'. I took apart a cheap player, it had 3 motors and a combo IR/red diode. Output will be low.

Do you know how i go about powering the diode? Would i need to get something online for me to be able to do it... or can i macgyver' something with what i already have?

If you have a multimeter, you can use the diode test setting to find which pins are correct. Usually, the diode will glow just enough for you to see that you have the right pins.

I would be very very conservative with how much current you give it. Perhaps someone else would have a better idea of where to start than me. With these cheap diodes I usually get some crappy batteries to power them. Heavy duty's or long life alkalines.
