[CDX reverse engineering]

I think I'm going to give up on this it's getting on my tits.

While I wait for laser modules I'm probably going to continue doing documentation like this:

This helps support my poor short-term memory.

yeah pretty much can't recover these cd drives, I'm dead in the water until replacements arrive, I think.

 

considered removing almost all of the electronics and just use the turntable+encoder information? I don't see the point of pre-fader effects.

I've done nothing except be inspired by your research. I'm going to need to fix my laser adjustment fuck up. I've got 2 cdx both are faulty so I feel a bit disabled for the moment, I've ordered a few replacement laser modules and will do some trial and error adjustments to see if I can get one working again in the meantime.

 

Besides doing nothing useful i'm reading through CXD3068Q to absorb some of it.

 

I hope to contribute something useful soon!

hmm,

 

I was just re-reading what you said previously about emulating the output of the CXD3068Q, I've also read through tons of CD documentation (red book etc) to get my head around this CDX situation.. I agree that the best course of action here is very likely to be emulating this IC's output.

 

I'm willing to invest some time on this project.

yeahhhhhhhhh... muchly appreciate the advice - that said it may be a bit late for me.. oops. I remember roughly where it should be but I imagine from what you have said that wont be enough.

 

ksm213ccm seems like a good replacement.

hmm anyone know what the cd laser potentiometer should be set to?

Nice to see this thread going, rasteri I recognise you from the skratchlounge I used the name 'turntablist tikka' there back in the day.
