Re: Blu ray diode

Im actually not sure, it was an older player that didnt work. I found it next to a *****ter lol. I put a cd in and it just wouldnt load. I dont have the scrap anymore, but i want to say it was a sony. I want to make a laser pointer with it, as it will be my first. Also, im not sure what host/module/driver i need. Any help is appreciated

Re: Blu ray diode

I have nothing to try to research the answer for you without that info unless you know the "X" speed, then I can speculate. Maybe someone else here might now more about Sony Blu-Ray players, but I'm out on this one.

Re: Blu ray diode

I guess I might hijack this thread a little instead of creating my own

I have a Magnavox blu-ray player with model no: MBP5130/f7

Can anyone help me figure out what diode is in here?

Re: Blu ray diode

I did some looking around, and i believe the model was Sony DVD Player - Black (DVPSR210P). How would I find out what the diode is?

Re: Blu ray diode

Also, can anyone tell me if this is a good deal, when considering the diode in the burner. what strength diode would be in this burner?
