Is this not overkill???  Get an older   CD ROM drive that
automagically plays the CD  and has it's own volume control. Heck some
even have skip forward and reverse. 12 volts and a case you  are all
set.

Yeah but the ones that I have don't automagically play the CD.
Do you know how to make them do that? These ones don't even have play
buttons.

How To Make The Adaptation

To be used as CD player, the CD-ROM drive doesn't need to be connected to
the computer. This way, it is possible to easily transform a CD-ROM drive
into a Car CD player. Sounds crazy? Not so. With this tutorial you will be
able to have a CD player in your car without spending almost anything.

The CD-ROM drive to be use may be of any type, from the first models ("1x")
until the most modern ones ("60x"). The only prerequisite is that the drive
needs to have is an earphone plug and volume control. And practically all
CD-ROM drives have that.

There are two great advantages in transforming a CD-ROM drive into a Car CD
player. First, who will want to break your car window to take CD-ROM drive?
And, secondly, since any type of CD-ROM drive can be used, you may take an
old drive that is just dusting away in your house (for instance, a 2x drive
from an old 386 computer), which brings the cost down to almost nothing.

To install a CD-ROM drive in the car, you will need a female power plug, to
be used to fit into CD-ROM drive power plug (that plug can be cut from an
old power supply) and a voltage regulating integrated circuit called 7805,
that may be easily found at electronic parts stores. You will also have to
buy a heat dissipator for the 7805 (sold at the same store).

The car battery is a 12 V one, but the CD-ROM drive needs two voltages to
work: 12 V and 5 V. The 7805 circuit is able to convert a 12 V voltage into
5 V (its pin 1 is for the input, its pin 2 is the grounding, and its pin 3
is the 5 V exit). Figure 1 shows the plan for the connection. The grounding
pin should be connected to the wires of the plug grounding and the negative
pole of the car battery, what is done by simply connecting that pin to the
metallic body of the car.

All you have to do is to make the connections shown in the above schematics
(don't forget to isolate all connections with insulating tape) and you are
set: you will have a CD-ROM drive working as CD player in your car.

The audio output will be made using the earphone plug. To listen to a CD,
you will have to use earphones. To have the sound come through the speakers
of the car, you will have to buy an amplifier with RCA inputs and a stereo
P2 (mini jack) x stereo RCA cable (the same type of cable used to connect
Discman units to amplifiers). The stereo P2 plug (also known as mini jack),
which is the one used for the earphones, should be fit at the earphone
output of the CD-ROM drive, while the RCA plugs should be fit at the input
of the amplifier. The volume control will be made using the volume control
in the CD-ROM drive.

A last warning: in most CD-ROM drives, the reproduction button (play) and
the advance button (skip) are on the same key. In other words, to skip a
track, all you have to do is to press the play button.

Frequently Asked Questions

Can the CD-ROM drive in use as a car CD player reproduce MP3 files?

No. If not connected to a computer, the CD-ROM drive will only work to play
audio CDs. Music CDs in the MP3 format are recorded in the CD-ROM format. To
read it, the unit forcibly needs to be connected to a computer. MP3 songs
are not played by the CD-ROM drive, but rather by the sound card of the
computer, and the machine processor is responsible for transforming the MP3
format into an audio format. Car CD players that play MP3 have a dedicated
processor capable of reading the CD-ROM format and of converting MP3 files
into audio ones. Since the common CD-ROM drive doesn't have such processor,
it can not play MP3 files.

Can the same adaptation be made so CDs may be played in a domestic sound
system?

Yes. To do so, the sound system must have an auxiliary input channel.
However, to prevent the sound from getting distorted, you will have to use
the audio output at the back of the CD-ROM drive and nor the earphone
output, as mentioned last week. To do this, you will have to take the audio
output cable from the CD-ROM drive and solder two RCA plugs - a black or
white one (left channel) and a red or yellow one (right channel) - at the
end that should be connected to the sound card of the computer. If you don't
know how to do that, contact an electronics technician. To feed the CD-ROM
drive you may use a power source from an old PC. One important detail: AT
power sources have an on-off switch, but the ATX ones don't. If you will use
an ATX power source, you will have to make a pin-14 connection (green wire),
from the main plug of the source to any black wire to turn it on.

Won't the CD oscillate too much?

That will depend on the unit used (its manufacturer and model). Of course
you cannot expect a CD-ROM drive to have the same stability of a car CD
player. Remember that our tip is to assemble a car CD player spending
nothing (or almost nothing). If you used our tip it is because you are
possibly not willing to buy a car CD player.

Why should the connection between the CD-ROM unit and the amplifier be made
using the ear phone output and not the one at the back of the unit?

That is because car amplifiers don't usually have volume control. If you use
the output at the back of the CD-ROM drive - which doesn't have volume
control either - the sound from the amplifier will always be at its loudest.
We believe that this is not convenient. If you should use the output at the
back of the CD-ROM drive only if you are to connect it to a pre-amplifier,
equalizer, mixer, or home sound system, since they have volume control.

CD

And a HUGE disadvantage of no anti-skip buffering considering car CD players
WITH built in radio, amplifier, full user controls and display, can be had
for about $50 or so new, and even less second hand. Better looks and easier
mounting is also a bonus.

Yeah well really why would you bother, you can pick up a DVD\CD\MP3\DIVX
player
from your supermarket for less than $50. Car audio, $200 buys the most
amazing car CD\MP3
players with around 30w RMS (Thats so much). They've even got remotes.
Excellent A/V gear is so affordable these days. Of course building your own
stuff is much more fun
but beyond the abilities or willing effort of most. I like making things,
it's as much about the process
and sense of acheivment as it is about the finished product.

You would bother because you don't have to add to our stockpile of
landfill.

BTW, given the rapidly dropping dollar. How much longer will we still have
cheap imports?

Given all the imported items that didn't come down in price as the dollar
rose, they shouldn't go up as the dollar falls.

There is that. My work are sending all their old PC's and etc to a PC
recycler.
Apparently breaks them down and recycles most them, Metals, Glass, Plastics.
I suppose the need is now being driven so the Tech is appearing.

Thanks for that. Do any computer store now provide recycling services?
Where do I find them?
