Volumio is a music player, but it’s certainly more than that. Volumio is a music operating system. It turns a normal PC or a smaller embedded device, like a Raspberry Pi, into a custom audio playing powerhouse, purpose built for making the most of your media collection.

Volumio isn’t like Kodi or any of the media operating systems based around it. Volumio is meant to function as the brain of a stereo system. It handles library management, playing Internet radio, importing music from networked sources, and serving it all from a sleek web interface.

Raspberry Pi ‘3 B+’ Review

A new PI is out, but is it a worth upgrade?

Before moving any further, it’s however important to note that this is not a brand-new product or a radical evolution of our beloved PI, but rather an incremental upgrade. So, if you’re still struggling to decide whether this upgrade is worth it, I’m here to help with some considerations.

Please note that we’re still testing the new Raspberry PI 3 B+, and those considerations are based on official statements of the Foundation, we’ll update this article as soon as our tests are done.

Raspberry PI 3B+

WHAT IS CHANGED

The hardware makeover of the Raspberry PI model 3 B+ covers basically 3 areas:

  • Slightly faster processor
  • Better thermal management
  • Networking

As we will see later, what really matters for us is indirectly related to point number 3: networking. But let’s see in detail all the 3 main upgrade areas.

The number of things you can do with a Raspberry Pi is astounding. For a little over $35, you can create a networked media server for streaming all your digital movies to your TV or give your existing printer wireless capabilities. And that’s just the tip of the iceberg.

If you’ve yet to decide on what you want to do with your Raspberry Pi, this project shows you how to turn it into a Chromecast Audio-like music streamer. This means you could set up several Raspberry Pis this way, connect each one to a speaker, place them around your house and stream music to each those speakers remotely in a highly configurable way. You can control the music from your phone, tablet or computer.

Build a Raspberry Pi Streaming Music Player

In this tutorial, I will be going through steps to making your very own Raspberry Pi music player. This process is pretty straightforward, so you shouldn’t come across any problems at all.

For this project, I am going to be using a pre-built software package called the Pi Musicbox. This software contains plenty of features & functionality that make it great as a Music player.

This project is a headless music player so you will need to use a different device to be able to control it. The good thing is you can pretty much use any device that has a browser to be able to interact with it.

  • Line out stereo jack
  • Optional landing for dual RCA phono connector
  • PCM5102A DAC over the Raspberry Pi’s I2S interface
  • pHAT DAC pinout
  • Compatible with Raspberry Pi 3B+, 3, 2, B+, A+, Zero, and Zero W
  • Female header requires soldering

LEGO Mindstorms EV3 Audio Streamed via Bluetooth Audio

Whilst displaying my Robots at a major Exhibition, I got to thinking that it would be great to pipe the EV3’s Audio to a Bluetooth Speaker, so my robot can be heard among the noise of a crowd.
Here are my notes so far on getting started with Connecting a LEGO Mindstorms EV3 Brick to a Bluetooth Audio Speaker:

  • Debian jessie is using BlueZ 5 and PluseAudio 5, which are fairly new. There were major breaking changes in these versions, so most stuff you find on the Internet will be for BlueZ 4/PulseAudio 4, so it does not work at all, so watch out.
  • BlueZ 5 dropped support for alsa [1], so the solution for now (until someone updates some bluez-alsa project for BlueZ 5) is to use PulseAudio.
  • PulseAudio 5 only supports the A2DP profile and not HSP/HFP [2] (although it his under development [3]).

I purchased myself a Sony CMT-MX750Ni Mini Hi-Fi System. It is a fantastic home audio device that plays from the following media: CD, USB, Audio In, iPod/iPhone, FM Tuner, DAB Tuner, Home Network (Windows Media Streaming), Internet Music Services via wireless and wired connection. The Sony CMT-MX750Ni is easy to use and allows access to all of your audio content, wherever it is located (with the exception of vinyl and tape). It is easy to set up and produces very good quality sound.
