Default cdrom as audiocdplayer....

In the dutch april edition of Elektor ( Elektuur in dutch ) magazine there is a cdrom-controller for using cdrom-players as audio cdplayers:

I just thought some of you would be interested in this :

PCB, partslist and software:

An excellent opportunity to start learning dutch

Just follow the links at the left for software and pcb layout. On the page I gave the link for you can see the partlist.

I do not understand why one needs that external controller? I just have one the desk: An old 150W ATX power supply 4 , a CD ROM from electronics junk jard with play and eject buttons at front, connected to the experimental AD1865 i made via spdif. It works, but mechanics is a little louder than a real audio transport.

What bugs me is that CD-Roms these days (with crazy speeds) make a lot of noise, even when playing CD-DA.
Listening to my music with a Bzzzzzzzzzzz is not for me.
I have a CD-Rom on a box (taken from a tape backup system), with internal PSU, RCA analog and SPDIF outs and I don't use it.

Most cdrom players have an eject and only sometimes a play button. No track buttons. Linear supplies are preferred over switchers.

A possibility to lower the spindle motor speed is a nice extra.

I think the Bzzzzzzzzz sound from your old tape backup system box. Is it switching power supply? Try other power supply souce such as Liner Power Source.

Default Check out Asus 52X cdrom player

at www.asus.com.
They have released a 'quiet' version of
their 'well-suspended' cdrom
transport. It is in the news section, but the
product is actually available in shops already.

cheers
