OK, here's another one that doesn't work.

I just picked up a Sony AW-G540A CVD/CD Rewritable laptop drive. Same problem. Plug it in, turn it on, and the disk starts to play and the >> and << buttons work, but if I hit the >/" button, the display stops functioning and the display stays the same even if the disk is changed.

Huang, anyone...any thoughts or suggestions?

Well, I have the Teac coming. Maybe it will work.

I did just try hooking up the controller that has not been working with the laptop drives to a full-size Pioneer DVD drive, and it works perfectly. So it's definitely something about many of those small drives that is causing your software to crash and lock up.

I'll report when I get the Teac and maybe I will have better luck. These things are pretty cheap but at this point I don't know how many I will have to buy before I find one that works. Not how one would like to proceed with a project!

Teac CD-224E laptop drive doesn't work either.

Drive spins up, but controller display just stays on "Checking IDE." Adapter board has pins soldered into master drive configuration and other drives I've tried were at least recognized.

Suggestions? I'm beginning to think this controller is just not going to work with laptop drives.

At last, I can report some success with a laptop drive, a Samsung/Toshiba TS-L462, after striking out with Teac, Sony and Plextor drives.

This one seems to work fine and is playing music. Looking through this thread, the only other success was with a Samsung drive, so I guess that is the direction until we have some other data points.

Project un-stalled!

That would be ideal, but it's outputting analog right now. I've been struggling to find a laptop drive than functions at all, and doesn't crash Huang's software.

From what others have said, most (or all) of the laptop drives have one big processing chip which includes everything, including a DAC, which means it might be impossible to divert a digital audio signal and use a better DAC.

When I get a chance, I'll open it up and run down the chip numbers, and see if I can figure out how it's put together. The best I might be able to do is bypass an op-amp and replace with transformers.

My main goal for this is portability, ao the quality level to beat are the toy-like diskman-type products, none of which even have a line out anymore.

I am using the similar Unit from DIYbiz, with an older china made cd rom drive - no name - but mechanically excellent quality.
I have not tried slimline drives, as I run digital out to a src 2496, and slimline models do not provide digital out.

hey, were did you get that enclosure?

Peter, may I ask you to give me the diagram of your panel please? I plan to make an enclosure like your one.

Plus, about the small buttons, were did you get the ones you mounted on the panel? And how much for the front panel?

Thanks a lot!

The buttons are just contactors, replacing the small buttons on the board that comes with the kit.
I got mine from:
http://www.thesource.ca/estore/Prod...ne&category=Switches+Switches&product=2750644

I removed all unneccessary parts - headphone output, volume control,
switches from the cd rom, removed the spindle weight with the bracket holding it from the cd rom housing - just cut it off nicely with tin snips - and after installing the stripped cd rom player into the rack case I measured carefully and cemented the bracket and weight on to the bottom of the top cover of the rack case.

As the stripped cd rom is still a bit higher then the case, you have to use shims - I went for aluminum strips - between the frame and the top cover or between both.
As for the panel layout - send me your email to member contact, and I will try to send you the file.
