1Step 1
Assemble your hardware
Once you have soldered the headers to your Pi Zero and the pHAT DAC, it is quick to assemble by popping the pHAT DAC onto the Pi's GPIO pins, and then securing UUGear's Zero4U as per their instructions here (http://www.uugear.com/doc/Zero4U_UserManual.pdf).

MoOde Audio, AirPlay and WiFi Access Point
As I am going to be using my Pi in my car, I needed a way of controlling my Raspberry Pi car audio player so when I found out that mOode now creates a WiFi Access Point (AP) that you can connect to as a way of accessing the user interface – all from a fresh install – I was suitably impressed! This is such a cool feature and solved my next problem before it even started!

3Step 3
Controlling the audio
As the Pi creates its own WiFi Access Point, thanks to MoOde's excellent built-in feature, I simply connect to this using my iPhone (any smart phone works) and open up the UI by navigating to moode.local in my browser. I can then queue up songs (before I drive away of course!) and enjoy the high-end sound during my journey.

4Step 4
Turning on and off
The last hurdle I needed to overcome was powering up and turning off the Raspberry Pi car audio player safely, without corrupting the SD card. I am well aware of the fantastic, but expensive to buy if you live outside the US, Mausberry Circuit Switch (I have used one of these in my Raspberry PiStation build), but given that installing this in a car requires some tinkering with the car’s electrics, I decided I didn’t want to risk this. Instead, I opted for a micro USB lead with an inline switch. This allows me to manually turn the power on, and once I have stopped and turned off my engine, I can login and shutdown the Raspberry Pi car audio player using the user interface. I can then kill the power using the switch.
