About the Author
David Lewin was introduced early to electronics and computers by TRS-80, Atari, and Commodore 64; he has never quit since then. He spends his free time watching out for technology for the next generation of embedded systems when he is not exploring philosophy.
David is a passionate and creative embedded developer who spent 20 years working for automotive companies such as Renault, Peugeot, and Faurecia, as well as for satellites with Thales Alenia Space. He currently works in Sophia Antipolis, the French Riviera Silicon Valley, designing industrial embedded systems.
A book is a real personal investment, and I'd like to thank Lisa for her patience, support, and advice. Thanks to my parents for supporting me in my early days; it is also thanks to them that I found the way to write to this book. Thanks to Sarah and Lisa as well. Thanks to Eric and Carol for their time and efforts. I'd like also to thank Neeshma and Larissa at Packt Publishing for their precious help. Besides, I'd also like to thank the open source community as they allow you to benefit from the BeagleBone hardware and software.
I would also like to thank Naoya, Rachel, and Jason (the syntaxic killer) for their great work as I really appreciate what they brought to the book.
About the Reviewers
Naoya Hashimoto has been working on system design and integration with open source software for years. In the past few years, his career and interests have been shifting toward cloud engineering mainly for AWS with orchestration tools such as Chef or CloudFormation.
He has reviewed Icinga Network Monitoring, Home Security System with BeagleBone, and Building networks and servers using BeagleBone, both by Packt Publishing:
Thanks to the author and project coordinator Danuta, who gave me this opportunity to review the book. I am very impressed with her work and this project because we can create a media center device with BeagleBone and open source software. I hope that we get more such opportunities to work with BeagleBone and other open source software.
Pei JIA holds a PhD degree in computer science from the University of Essex, with full financial aid by Overseas Research Studentship (ORS). He specializes in various computer vision algorithms (particularly, 2D and 3D morphable models) and has extensive embedded machine vision experience. He is the pioneer of advocating all kinds of open source, both software and hardware. He has just designed his own smart house in beautiful British Columbia using a BeagleBone Black-based control center. Recently, he launched his enterprise, Longer Vision Tech., in ShenZhen, China, which focuses on designing intelligent vision systems. He has been keeping a close eye on the electronics market and a cooperating closely with the connections with in Seattle and Silicon Valley.
It is my pleasure to be invited to review this book, BeagleBone Media Center, whose title attracted me at first sight. Various single-board computers (SBC) have now emerged, such as BeagleBone Black, Raspberry Pi, Banana Pi Pro, and so on. It's certain that BeagleBone Black has been playing an important role in the development of SBCs. This book elaborates on how to design a media center based on a BeagleBone Black SBC and it comes down to some open source software, such as MediaDrop. I strongly suggest that you read this book (in particular, open source advocators).
Chidananda Matada Shivananda is an electrical engineering graduate who specializes in system dynamics and controls at Villanova University. He has 2 years of industry experience that involves automotive engine management software development at Robert Bosch, India. His interests lie in embedded systems, mobile robotics, and control systems.
I would like to thank Packt Publishing for giving me this wonderful opportunity.

Preface
The still young market of embedded boards is growing each day, owing to the Raspberry Pi effect. These single-board computers help you solve common problems, such as analyzing a network, programming without a PC, and others. The BeagleBone Black has all of these features, but at the same time, you can broaden your horizons to perform interesting tasks using the expansion capability of the board. Whether you use the basic version of the board or improve it with different accessories available in the market, this board will come in handy to help you decide and create the various tasks you want to perform with it. This book is designed to provide you with the knowledge to explore the world of BeagleBone Black.
Welcome aboard!
What this book covers
Chapter 1, Transforming Your BeagleBone Black into a Media Server, begins with an introduction to help you better understand why it is in your interest to have your own personal server. This chapter then describes the steps required for the installation of an improved multimedia server on steroids.
Chapter 2, Media Management, Shares, and Social Activities, gives indications to use your new server in a connected world. It begins with an explanation of the workflow that needs to be followed; there are also indications to understand what an administrator should do. The chapter ends with social sharing to let you share your contents with your friends or members of your family.
Chapter 3, Examples of Real-world Situations, deals with security because a connected server also needs to safely manage your publications. This chapter introduces you to the security role followed by two scenarios based on real-life experiences: one for a house, and another for professional activities.
Chapter 4, Getting Your Own Video and Feeds, discusses how to improve the existing server by giving you the opportunity to provide your own personal video streams. This chapter gives you the keys for hardware detection. It also presents a different topic that is still based on multimedia: configuring the server for RSS feeds.
Chapter 5, Building Your Media Player, describes the real USP of the BeagleBone Black: capes. Thus, it gives you a way to extend your board in order to create funnier and useful projects. In addition, with this exciting chapter, you will be able to build a device that can display movies and play music without making your imagination compromise because you can also extend this extension board through connectors and additional networks.
Chapter 6, Illuminate Your Imagination with Your Own Projects, lets you enter into the software part of the book using "Matrix Revolution," a fun project with funny tools: you'll use the 8 x 8 bicolor LEDs matrix from Adafruit connected to the BeagleBone Black. After a good introduction to the hardware of the board, the remaining part of this chapter is then split into three examples, starting with a simple example that allows beginners to start smoothly in Python and understand the main programming concepts related to a server and a client. This is followed by an improved version of the first example with a GUI as a laboratory for your experiments. It finally ends with a totally different example written in C++, which is a pattern generator, so you'll be able to display every disco pattern you like.
Appendix A, Troubleshooting and Tricks to Improve Your Server, covers the topics that will help you resolve issues that you might face while working with your servers, including some useful tools and troubleshooting steps.
Appendix B, Ideas to Improve Your Server, introduces some ideas to improve your server functionality.
What you need for this book
To run the book's examples, you will need a running Python environment, including the virtualenv package. The source code will be available from the dedicated GitHub repository and website as well. In all cases, Chapter 5, Building Your Media Player,and Chapter 6, Illuminate Your Imagination with Your Own Projects,will discuss how to install, compile, and run the examples.
Who this book is for
This book is intended for those who want to overcome the limitations of standard projects by learning electronics and programming and by using their imagination, knowledge, and passion.
