How to Add AirPlay to Your Car for High Quality, Wireless Audio

I was fed up with having so many cables floating around in my car and getting tangled, and I wasn’t happy with the compressed audio quality with Bluetooth. So, I came up with an awesome wireless audio solution. If you're bold enough to pop open an Apple AirPort Express and modify its innards, here’s how to hack Apple AirPort Express to put AirPlay in your car.

Note: Ben's original has been edited down a bit to clarify things for the non-technically-inclined, so if you want the original version, go here.


AirPort Express: $99
Car with an aux input in the stereo and a free “cigarette lighter” power plugStar/Torx screwdriver: $8Regular screwdriver: you probably already have oneUSB cable: we all have spares of these too!Some standard wires5V to 3.3V DC stepdown converter: $4A soldering iron & some solder: $8Super glue: $5Cigarette lighter-to-USB converter: $5-$15A little electrical tape: $5Okay, deep breath. First, you’ll need to modify the AirPort Express so that it draws power from a USB cable, instead of its usual household plug. In this post in the North American Subaru Impreza Owners Club forum, user “enjoiful” describes one technique for this. (You might want to check out his or her photos too, for help with this part). Basically, to pop open the AirPort Express, stick your regular screwdriver in the seams at the corners and try some twisting and prying motions. It should pop open easily.

Unscrew all of the circuit boards from the AirPort Express. You can get rid of the L-shaped power supply, because we’re going to wire the USB power to the 5V-to-3.3V converter and use that instead.

Cut the USB cable, and peel the wrapping towards the larger plug (the one that normally connects to your computer), because you want to keep that side. This will reveal four wires:

We're only interested in the red and black wires inside of that USB cable, because there’s no data coming over the USB cable. After threading the wires through the hole in the side of the AirPort Express (pictured above), solder the black one onto the ground of the AirPort Express (see photos below).

Then, connect the red one to the VIN (voltage input) wire of the stepdown converter, which is green in this photo, and tape around that connection like this:

The stepdown converter has an output wire leading out of it, which is blue in the above photo. Solder that to the power input of the AirPort Express, as pictured above.

Finally, solder the stepdown module’s ground wire (green in the above photo) to the AirPort Express’s ground. So, that’s two wires connected to the AirPort Express’s ground connection—black and green.

When you’re done with all the soldering, you should be looking at something like this:

You’ve made it through the hard part (hopefully without melting your brain or burning down your house). Congratulations! Now, you’ll want to super-glue everything into place so that it doesn’t jiggle around, potentially causing the solder to break, as you drive over your city’s pothole-riddled streets.

Snap the AirPort Express back together. Then, use another little bit of electrical tape to seal up the hole on the edge of the AirPort Express, so that dirt and dust doesn’t get in there, like so:

How to Add AirPlay to Your Car for High Quality, Wireless Audio

It’s time to use this thing. Put it in your car, connect the USB power cable to a cigarette lighter adapter, and plug that into your car.

Then, take the audio cable that came with the AirPort Express and connect that to your car’s input. But wait! You’re not done yet, because you’ll need to set up the AirPort Express and your iPhone or iPad the right way (or Android, because those can totally support AirPlay, as weird as that is).

This looks a bit convoluted, but it’s not, and you only have to do it once.

With the AirPort Express powered up and running, fire up Apple’s AirPort Utility on your laptop, in the car. (You can also do this before tackling any of the steps above, but we wanted to make sure you make it this far before bothering with the software tweaks.) AirPort Utility will display your modified AirPort Express in a list similar to this:

How to Add AirPlay to Your Car for High Quality, Wireless Audio

Click the device and select "Edit." First, give it a name and a password so you can connect to it later to configure it.

Click the "Internet" tab. Choose “Connect Using: DHCP,” and leave everything else blank:

How to Add AirPlay to Your Car for High Quality, Wireless Audio

Then click "Internet Options." In the Configure IPv6 option, choose Local-link only and hit "Save":

Now, head over to the "Wireless" tab. You want to set the network mode to ‘"Create a wireless network," and give it a name. Select your security level and give it a password–this will be the password you and your friends will use to connect their devices to your car’s wireless audio system:

How to Add AirPlay to Your Car for High Quality, Wireless Audio

Click "Wireless Options," making sure the details appear correct for your region, and press "Save":

How to Add AirPlay to Your Car for High Quality, Wireless Audio

Almost done. You’ll need to select the "Network" tab and set the Router Mode to "DHCP and NAT," like this:

How to Add AirPlay to Your Car for High Quality, Wireless Audio

Then, click "Network Options" and set the DHCP Lease time to 1 day. Set the IPv4 DHCP range to to 200, and make sure "Enable NAT Port Mapping Protocol" is selected. Hit "Save":

How to Add AirPlay to Your Car for High Quality, Wireless Audio

Okay, now click the "AirPlay" tab. Make sure "Enable AirPlay" is checked. You can give the the speaker a different name if you wish, but I just left it the same as my AirPort Express WiFi name. You can also set an AirPlay password, but there’s no point, really, because people will already need a password to connect in the first place:

How to Add AirPlay to Your Car for High Quality, Wireless Audio

Click "Update" to close the dialog and drop you back to the main AirPort screen. From here, you'll see the little icon next to the name as an orange dot, and the light on the front of the device will also be orange. To stop this from happening, click the device in the AirPort utility (as per the first screenshot in this section), and click each of the warnings that appear and select "Ignore," as we don’t care about them.

This will turn the little light green, and you’re almost ready to go. And remember, you won’t have to do any of the stuff above this again—it’s locked and loaded. However, you do still need to set up your iPhone for this to work, too.

How to Add AirPlay to Your Car for High Quality, Wireless Audio

You need to make your iPhone, iPad, or Android connect to the AirPort Express to send music, but to the cellular data network for everything else (including streaming music). We’re going to walk through the instructions for iOS here; Android people using these apps or these ones can apply similar principles on that platform.

Open the iOS Settings menu, tap WiFi, and tap new AirPort Express network. This will connect the iPhone or iPad to your new car-based WiFi network — but you’ll find that because the AirPort Express doesn’t have an internet connection, the internet won’t work on your phone. But we can fix that. Tap the blue arrow next to the name of the AirPort Express WiFi network to view more options.

From the screen (pictured at left), select "Static" as the type of IP address, and then enter the following IP address and Subnet Mask :

IP Address : (for example)
Subnet Mask:

Make sure you leave Router, DNS, and Search Domains blank! This tells the iPhone that it should use its cellular network to route internet traffic rather than trying to do it via WiFi.

And you’re done! Just one thing to keep in mind here though: When you’re connected on your AirPort Express WiFi network, the data icon at the top of your iOS screen won’t look like the WiFi network symbol, the way it normally does when connected to WiFi. Instead, you’ll see the cellular icon—E, 3G, 4G or LTE, depending on your data plan. Never fear, your phone is actually connected to the WiFi network for the purposes of AirPlay, just like we want it to be.

AirPlay on the Highway: Put AirPort Express in your Car for Wireless Audio Awesomeness |

Twitter software engineer Ben Novakovic, one of the guys who built We Are Hunted, which would eventually become Twitter #Music, is a clever person. In his spare time, Novakovic devised this way to modify an Apple Airport Express so that it runs efficiently in your car, allowing you or any of your passengers to play the music on their phone—or even stream it using Rdio, Spotify, Twitter #Music, or any other app.

Do You Still Use a Paper Resume?

Between job sites and online applications, paper resumes may seem a bit superfluous today. But many companies still accept, or even require, resumes on paper. What's your experience with this?

Whatever the format, the resume itself isn't going anywhere soon. We've talked before about whether you should use a paper or online resume. For online resumes, we've walked you through the modern application process. We also covered how you can make a bigger impact with your resume and how to format it so it gets past screening software.

So, we'd like to know:

Wipe Out a Mistyped Terminal Command with Control + U

Wipe Out a Mistyped Terminal Command with Control + U

OS X (and Linux!): As much as we love the command line, because it can do so much more so much faster in many cases, you can make a mistake pretty easily. If you do, just wipe out everything you typed in an instant with a simple keyboard shortcut: Control+U.

When you press those keys, the entire line goes away. That is if you're at the end of the line, at least. If you move the cursor to the left, it'll only delete what's to the left and retain the text to the right. It's a simple thing, but when you make an error it saves a lot of time. If it didn't exist, you'd have to sit and press the delete key until every individual character disappeared.

Zombie in a Pot- A Fun Prop/Decoration

IMG_0477.JPGI've always wanted my own zombie, but not one of those run-of-the-mill zombies you can pick up during any old apocalypse. No, I wanted my own homegrown zombie. So I went down to my local black magic practitioner's store and bought me some organic zombie seeds. A few months of tender care later I had my own zombie! This is fun, easy to make, and great for Halloween. 

If you like this please vote for me in the Zombie Contest!
