I found what probably is a dac nearby the headphones out.

Its a SO8 package and its written 3543 1t65 or ( IT65) on it.

anyone heard of this?

anyway, the drive has digital out, what if I use a external DAC? anyone think its possible?

Hi
I have an experience of using the CDROM to be the transport, actually I'm using this tranport now.
The most important thing is that your CDROM must have a "PLAY"
key on the front panel at least, or you have to build a controller of it.

Second, you need a power supply to connect to the CDROM, the easiest way is using a PC power supply, but my suggestion is that build a power supply(12V and 5V) for it by LM317 or 7805.

Third, if you want to get high quality sound, using the digital out(2-pin) instead of earphone plug or analog output(4-pin). But it means you need a DAC.

A little C is advisable for controlling the drive via the IDE port, not only to provide basic functions such as skip, search, pause etc., but also to setup the drive not to spin up the CD to 52x speed - you want a quiet environment to listen to music.

I've bought a book on the IDE interface to figure out an easy way how to do this with an ATMEL controller. I'lm limited in time at the moment, but I'll post software and hardware when I'm done.

The digital out at the back of most CD-ROM drives (never seen those at DVD-drives, though) is S/PDIF format, but at TTL level. It can be converted to standard S/PDIF easily. There have been circuits on the forum.

thx for the replies.
Yhea, I'll make a DAC
( the only problem for now is the price of the ics.. but..I'll figure out a way to get em)

Yhea, I have no problem making a psu, got the parts here, and the cdrom drive has a play/skip and stop button.
I'll make some kind of remote control too.

The part where I lack knowledge is as AMT-freak stated, the ide interfacing, to force the player not to spin at 52x all the time cuz its really loud, and to have other functions too
(maybe track name? I have some exprerience controlling small lcds via Paralell port maybe that could be possible?)

I can make a solid box for it.. using like thick aluminium or thick acrylic.

for now the problem is all the interfacing.

I believe when a CD-ROM is playing back an audio CD, it defaults to 1x speed (unless the software requests higher speed, such as for audio extraction) anyway?

Stay clear of those built-in DACs. They are no good for hifi. Use the S/PDIF instead signal and connect it to a decent DAC. There are lots of designs on the forum and around the web. Have a look at the non-oversampling designs, they are really simple and, according to some, sound great.

I use a dvd player for playing my audio cd's and it plays them at about 2500 rpm. It must read, wait, read, wait, etc.

I've seen pc apps that force your cd drive to work like at any speed you choose, so it should be possible to force it at 1x or 2x.

But I really suck on that side :|

Any recomendation for a decent dac? (not too expensive stuff (samples?))
