Pimoroni Pirate Radio tweak; aka 'Talk to me Sweetie!'

You know what's super annoying? Not knowing the ip-address of the server you're trying to access. I could scan the network and find the right machine. But, I'm lazy. And, the server knows its own ip, it should simply tell me.

This is something I believed my Pirate Radio could manage. When the pHAT BEAT bonnet gets installed it sets itself up with a daemon in /usr/bin. Technically I installed it twice (once for spotipy as well). I don't know if the code differs, but as I installed vlc-radio last, that's the code I will play with.

Think it through. I've just booted up the server. The volume and power buttons do very necessary jobs, so we'll leave them alone. The fast-forward and rewind buttons start playing a station/cycle through stations. Very useful if you can't be bothered finding the ip-address. That leaves Play/Pause, which doesn't do anything until a station has started streaming. And if I have access to the web interface, well I can do that very job there. That's it, I'm sacrificing Play/Pause!

In the end I simply replaced line#204 with a call out to my script;
(making sure to import it at the top of the file. Let's hear it for the wonders of Open Source!)

What script you ask? A simple one, to parse the wlan0 ip from ifconfig, and then a call to text-to-speech to actually read it out loud to me.

You'll probably need to install the text-to-speech stuff;
sudo pip install pyttsx
sudo apt-get install espeak

Then save this as a file named (or whatever) into /usr/bin

#!/usr/bin/env python

import os, pyttsx, time

def read_ip():
f = os.popen('ifconfig wlan0 | grep "inet\ addr" | cut -d: -f2 | cut -d" " -f1')


print your_ip

if __name__ == '__main__':

And sure, give it a reboot to make sure the changes are picked up.

Now, when I press play the Pirate Radio reads out its ip-address to me! So handy.
(Note; if you press play with monitor and OTG cable attached, it'll probably crash and reboot. So don't do that.)
