Default old DVD player

I just harvested the diode from an old DVD player(not burner) lying around. It was originally from my computer but I upgraded to better ones. I connected the + to one of the pins and - to ground. Nothing happened, am I doing something wrong? Or is it IR and I can't see it?

I'm practicing on this so when I have a spare dvd burner i'll know what to do

If nothing happened you more than likely killed your diode. You can't just hook up power to the diode. If you did, your diode is probably dead. A DVD player diode wont do anything.

You will stil get light if the diode is working. Use a multimeter and check the thing with a diode checker. it provides enough current to make the medium glow but not lase. so you'll see red and not enough to blind you. Although with just a dvd player laser your only looking at maybe 5mw MAX.

I'm pretty sure in that page it hooks that batteries up to the diode without any regulation, and thats a burner too. So with a player you will no matter what kill a player diode if you hook up 2 AA's to it. Oh yeah actually a girl wrote that page, so you have to refer to the author as 'her' instead of 'him'

i just took apart a cd writer from an used computer. will this give me better results? if not 2 AA batteries, then what? And as for the wiring, is it basically any kind of metal wire will do? I just took 2 wires i found within the player and taped it to the battery.

Be careful!!! A cd writer is infrared...you will barely be able to see it.....it is easy to damage your eyes on account of this.
