RPI 3B (to start with)
Install the latest version of Raspbian and configure to work headless.
Afterwords, update:
sudo apt update
Airtunes
This tutorial involves configuring the the open-source AirPlay receiver called Shairport Sync. Most of the contents found in in this section were directly lifted from here.
This software allows the Raspberry Pi to act as an AirPlay receiver by implementing Apple’s proprietary protocols so that it can stream music, from the output audio jack to the auxiliary input of the FJ’s amplifier.
This setup will allow you to play music from any AirPlay-enabled device to your Raspberry Pi meaning you can use any iPhone and some Android products with a compatible app installed.
First. we need to install several different packages, run the following commands on your Raspberry Pi to install all of the packages that we need.
sudo apt install autoconf libtool libdaemon-dev libasound2-dev libpopt-dev libconfig-dev sudo apt install avahi-daemon libavahi-client-dev sudo apt install libssl-dev
We will now clone the shairport-sync source to OpenFJ.
cd ~ git clone https://github.com/mikebrady/shairport-sync.git
We can now build and install the Shairport software.
cd shairport-sync autoreconf -i -f ./configure --with-alsa --with-avahi --with-ssl=openssl --with-systemd --with-metadata
The autoreconf command setups the basic config file. The configure command further sets up the build system, telling it to utilize the ALSA audio backend, the Avahi network and set it to use OpenSSL for encryption.
With the configuration process now completed we can compile Shairport-sync and install it.
make sudo make install
To enable the Shairport Sync software to start automatically at system startup:
sudo systemctl enable shairport-sync
sudo service shairport-sync start
On an AirPlay-enabled device Openfj should appear in the devices list.
There are several different things we can do to improve the sound quality. The first of these is to change update the RPI firmware to a newer version of the audio driver.
sudo rpi-update

'rpi-update' should only be used if there is a specific
reason to do so - for example, a request by a Raspberry Pi
engineer or if you want to help the testing effort
and are comfortable with restoring if there are regressions.
DO NOT use 'rpi-update' as part of a regular update process.

*** A reboot is needed to activate the new firmware
Once the firmware update has completed, turn off the RPI and remove the SD Card, and mount into a reader connected to a computerto modify the RPI /boot/config.txt on the SD Card, with the following new line to this file.
audio_pwm_mode=2
Insure the analog jack is the main audio out and not the HDMI output.
We can utilize the following command in the Raspberry Pi’s terminal to do this.
amixer cset numid=3 1
Now modify the volume db Range that Shairport uses by changing the configuration file:
sudo vi /usr/local/etc/shairport-sync.conf
Find
// volume_range_db = 60 ;Copy
Replace with
volume_range_db = 30;
Finally, reboot OpenFJ:
sudo reboot
GPS NMEA
Plug in the Garmin 296 GPS with a USB cable.
Does the RPI see the UPS?

Device Support
Check for device support:

This iw command should produce a list similar to the one below. Look for the wireless device that you intend on putting into monitoring mode (phy#1).
Now determine if the device can support monitoring mode. From the output of the iw phy phy1 info command, look for a section titled Supported interface modes:, and look for * monitor within it.
If this is not present, then this wireless adapter will not work.

Configure wireless adapter
Edit the interfaces file, including allow-hotplug, and disable the wlan1 interface from automatically being assigned an IP address. Also, set up the monitor mode of the interface before it is brought up by the operating system.
We then proceed to delete the wlan1 interface as we do not require it for what we are doing.
sudo vi /etc/network/interfaces allow-hotplug wlan1 iface wlan1 inet manual pre-up iw phy phy1 interface add mon1 type monitor pre-up iw dev wlan1 del pre-up ifconfig mon1 up
