Thx a lot, MCLL.
Controller layout is already done, as soon as I have the first useful reactions from the drive I will report.

You are Welcome...Wait you project

Great thread,

was looking into this for myself some time now.

Got some nice link for the casing.

You could add the display via some angled piece of plexiglas.

Have you seen this side,

Already a controller with display.
Not sure if the software to control the display is already finished.

But if you enter a CD in a CDRom drive, the drive is used to spin up to high speeds.

I could get very noisy

BTW mgb's link is very usefull

the drive is used to spin up to high speeds

No problem at all.
You can force it by command to rotate at x1 speed.

Hello All,

Would it be possible to include CDDB and / or CD-text inside the firmware? Maybe it's possible to also include a harddrive on the same bus to store the cddb data.

just some thougts,
MGB

Konnichiwa,

Sounds ABSOLUTELY great. However, I would like to throw in a few little things from the side.

How about using DAE Mode, including control of spin speed?

This way we can use up all the old 72-Pin Ram Sticks (or whatever we have) and get the Reader to fill a local buffer (say 10 second read ahead) asyncronously with data, including multiple reads on errors.

The Data can then be clocked out via I2S or S/P-DIF & AES/EBU via either external or internal clock (selectable via simple detect - external 44.1KHz master clock present, use this to clock data out, otherwise use local Osc).

Howzdat? It will take more work programming but should easily match the best transports out there.

The noise issue from the Drive can be adressed by compliantly mounting the "slot" for the drive and fitting an openable front panel that closes normally with some decent sound deadening.

Perhaps someone could make a nice 1/2 width case for that too, this would make a great kit.

Here is something I serched from web sites.

We should add support for RC5 decoding as well ! (remote control)

[Holger Barske]

RC5 ist definitely on the to do list, as the code for decoding this is rather common.
