Building a Jukebox out of an Old Mac
The sparking of an idea.
Digital music is becoming a larger part of our lives. By this point most of
us have used iTunes to play music on our computers while we’re
working or relaxing at home. Let’s face it, iTunes is a pretty nifty
app that is (at least in my humble opinion) just as good as any other music
player out there.
Ever since iTunes was first released, there have been people who’ve been working on integrating it with their home stereo systems. Apple’s introduction of the AirPort
Express made this a lot easier. But that method has two minor drawbacks: the $130 price tag and the fact you have to have your computer on and/or conveniently located to use it.
In the OWC Tech Department, we wanted to have some background music
playing, but didn’t like most of what the local radio stations
offered. For a while, each of us played music off our individual machines
via iTunes, but it wound up in a small “stereo wars” situation:
each of us started turning up our music to drown out the others’.
We finally decided that we should pool all our music into one central
repository and play it from there. We had an old iMac to use as the central
unit and we had enough speakers and wire to run a speaker to each
person’s desk, so we could control the volume individually. It took
about a month’s worth of lunch hours working on thing, but it finally
got up and running the way we wanted it. There have been some tweaks over
time, and now the Tech Jukebox is a thing of wonder here at OWC. We in Tech
are quite proud of it.
This series of articles describes the method we used to build our jukebox.
It does not go into the details of how to do each step, as much of it is
specific for the computer itself or the personal tastes of the user.
However, if you have decent knowledge of how to perform upgrades on your
machine, this method should help get your own jukebox up and running.
The first part of this series is going to be mostly hardware-oriented -
Getting your old computer up and running as a bare-bones music player. The
next article will discuss some of the customization options to make your
jukebox more automated, customized, and overall drool-worthy.
Building the Unit
A spare computer and display - This is one of those things you
either have or don’t have. Some people are fortunate enough to have a
spare Mac sitting in their attic, basement or other storage space gathering
dust. Others have been able to find great deals online or at rummage sales.
For our jukebox, we used an original iMac. In truth, though, you can really
use any Mac with a G3 processor or later. If you are using MP3s or Apple
AAC files, like we do, you can get away with a Beige G3 or original iMac.
Some of the other codecs may require a zippier processor.
A large storage device - Audio files take up space, and the
higher-quality they are, the more space they take up. You either want a large
internal drive(in older machines, you’re going to max out at
120GB drive, unless you add an ATA card) or an external drive, such as our
OWC
Mercury Elite or OWC Neptune drives. For our project, we used a 20GB
internal drive, as we had an extra one laying in a drawer, though as our
library grows, we will likely need a larger drive..
Some decent speakers- You can play the music through your Mac’s built-in speaker, but, let’s face it, the built-in speaker is not exactly the pinnacle of audio reproduction. If you have a set of nice
computer speakers, go ahead and use them. If you’re running it
into your home sound system, all you need is a simple, inexpensive 1/8” Stereo minijack to RCA
adapter cable.
A network connection - While this is mostly optional, having a
network connection enables a lot of options that you wouldn’t have
otherwise, including auto-download of album art, system updates, access to
the CDDB, and remote control.
OS X - the latest versions of iTunes require OS X. We generally
recommend the latest version your computer can run. (If you’re using
a Beige G3, you can use XPostFacto to install 10.3.x, which will get you the
latest version of QuickTime, as well).
Now that we have all the parts we need, we can get started.
Step 1: Get the lastest version of your software installed.
- Boot to your OS X CD
- Open up the Disk Utility from the Installer Menu and Erase the Hard
drive. If you need to partition your hard drive, do it here. A standard
OSX install, by itself, takes up approximately 2GB. A partition of
about 4GB should be enough to install OS X and have enough room to
work.
- Restart the computer and install OS X. Use the “Custom”
install option, as you can choose not to install a lot of the
unnecessary applications. About the only thing you need to install are
the Base System and Essential System Software. Avoid the temptation to
install Additional Applications. Although it includes iTunes, it also
includes things for this setup that are unnecessary, such as iMovie.
Choosing just the two items mentioned above will put the bare minimum
system on your computer, allowing you to use the maximum amount of
space for your music.
- Once the OS has been installed, download
the latest version of iTunes and install it. As mentioned above, it was part of the group that was not selected, so it was not installed. By doing it this way, we are able to get the most recent version without any extra space being wasted.
- Run Software Update to make sure you have the latest versions of
everything installed.
Step 2: Set Up iTunes.
- Once you have iTunes installed, before putting any music in, make sure you have your music library stored on the largest volume. If you have a single drive, you shoudln’t need to change anything and you can skip to part 2e. If, however, you partitioned your hard drive or are using an external drive to store the music, you will need to change the library’s location.
- Create a folder named “iTunes Music” on the volume you
want to store your music.
- Open up iTunes and go to the Preferences.
- Under the “Advanced” section click the
“Change...” button and select the folder you just created.
Then click the “OK” button. This will tell iTunes to store
all music there. We have also found it best to check the options to
keep the iTunes Music folder organized and to copy files to the music
folder when adding to the library.
- Add music to your music library by ripping them from CD’s,
buying from the iTMS, or however else you want. All the music
should be automatically stored and organized into the Music
folder.
Step 3: Connect your computer to the speakers.
- If you’re using powered speakers, hook them up to the
computer as per the instructions that came with them.
- If you’re hooking it up to your home stereo, hook the
computer up to a line-in using the 1/8” minijack to RCA adapter
mentioned above, set the iTunes player volume to Maximum, then use the
system volume to set the output volume so that it produces a line-level
signal. The easiest way to do this is to play some music from another
source (such as a CD player) and switch between that source and the
Mac, adjusting the volume on the Mac until the output is at about the
same sound level.
Step 4: Enjoy your new jukebox!
You can now play music from your iTunes music library, just like any other
stereo component. For long playlists, the Party Shuffle feature works quite
nicely. Impress your friends!
At this point you have a nicely functional jukebox to play your music.
However, as it sits right now, it is little more than just a really large,
not-very-portable iPod. In the next installment, we will go over
customization options ranging from the fairly simple to “darn near
insane”, all for little-to-no cost over your initial investment.
