Same seller (Sunnking) has another auction for one individual diode module up you could bid on. Just search his ebay store for 520ma, its the only thing that will pop up.
I gutted an 360 HD-DVD drive a while back but was unsuccessful at harvesting the violet LD. Either I killed the violet from ESD or while trying to determine the pinout.
The lens assembly model# is PHR-903T, It has what appear to be 2 LD's. a 3-pin and a 4-pin . Significantly less intricate...
what I can't just plug them into the wall socket???
Ahhh just messing with ya they will be regulated, I don't think I could even bring myself to drive one unregulated even if I had to wait a month for the driver components to arrive.
