How cool would it be to have audio streaming concurrently in every room of your home? It’s ideal for playing music at a party, but equally useful if you’re simply pottering around doing the housework and don’t want to miss a key part of the audio book you’re listening to. Traditionally though, multi-room audio used to be an expensive setup. Not any more! The Raspberry Pi can take care of that, giving you your favourite sounds wherever you are. Find out how in our feature this issue! Also in this issue we take you through the second part of building your own Pi-based version of Rock, Paper, Scissors, Lizard, Spock, as well as looking at networked sensors, Open GL and more. Enjoy!

set up a multi-room sound system

In this article we are going to use Logitech’s Squeezebox Media Server and the squeezelite client to create a multi-room audio system. The media server can stream audio to each squeezelite client and also synchronise the playback between multiple clients if desired. Logitech open-sourced the Squeezebox software after officially discontinuing the hardware line. The media server can be controlled from a web interface or various smartphone applications. Unfortunately, the Spotify plugin (specifically the third-party Spotify plugin by Triode) was partially broken at the time of writing. Search isn’t working, likely because the Spotify API has been updated since the plugin was last updated. Instead, the server can be pointed at a music directory on the Pi. You can either put music directly onto the SD card or connect up a USB…

What inspires you to create the work you do? Tell us about your process. In my work I fuse modern technology with traditional crafting, creating a balanced blend of function and aesthetics. Over the past couple of years I’ve dedicated myself to making unique gaming consoles that cover different shapes and sizes. These consoles are often personal tributes to the golden age of arcades, where great games were created out of limitations and big physical buttons gave us instant feedback and total control; a sense of interaction that differs a lot from today’s flat shiny surfaces and touchscreens. In my designs, I play a lot with historic norms and standards, and I give objects new functions, new values. The smashed-up references in my work have a triggering effect on the customer, I guess.…

master essential sense hat skills: part 2

You will probably have played Rock, Paper, Scissors in real life. The issue with this version is that there are only three possible outcomes other than a tie. Sam Kass and Karen Bryla invented an alternative version which adds “Spock” and “lizard”. “Spock” is signified with the Star Trek Vulcan hand sign, while “lizard” is shown by forming the hand into a mouth. Spock smashes scissors and vapourises rock; he is poisoned by lizard and is disproved by paper. Lizard poisons Spock and eats paper; it is crushed by rock and decapitated by scissors. This tutorial walks you through creating your own SenseHAT version of the game.

networked sensor display with pimoroni scroll phat

We are going to create a networked sensor display with the Pimoroni Scroll pHAT. We’ll take a look at the hardware, what’s included and how to install the required Python libraries. Then we will tour the library’s source code and code some examples that have been contributed by the open-source community through GitHub. Once we are familiar with the library, we will go on to set up our chosen sensor on the first Raspberry Pi and connect the screen to our Pi Zero. We’ll learn about how to use Redis (which is an open-source pub-sub noSQL database). Redis is our connective tissue, publishing events that our Zero will subscribe to and then display on the Scroll pHAT. This saves on the complexity of implementing a web-server or going even lower level…

handle opengl on your pi

Many of the examples we have looked at in this column have been programs that run on the console. This issue, we will be taking a look at how you can include 3D graphics within your Python code. The hardware on the board includes a GPU, so you should be able to take advantage of everything this computer is capable of. Since we are going to be playing with graphics, this means that you will probably want to have an actual monitor connected to your Raspberry Pi. If you don’t have one, you can connect to your Raspberry Pi over SSH with X11 forwarding turned on. As long as you have an X11 server on your desktop, you can see the display on your local machine. To get access to…
