Acknowledgments

      I would like to express my deep gratitude to the Raspberry Pi Foundation for allowing me to set my creativity free on their marvellous invention. In particular I’d like to thank Alex Bradbury and Dr Sam Aaron for their enthusiastic encouragement and patient guidance. Their willingness to give their time so generously is very much appreciated. I would also like to thank David Whale and the Raspberry Pi Community for their useful critiques of this work. Thanks to Jennifer Mayberry for her design work and Sarah Wright for much of the art.

      Introduction

      ARE YOU AN intrepid adventurer? Do you like to try new things and learn new skills? Would you like to be a pioneer in creating technology? Do you own a Raspberry Pi, or are you considering getting one? If the answer is a resounding “Yes!” then this is the book for you.

What Is the Raspberry Pi and What Can You Do With It?

      The Raspberry Pi is a computer. A very small computer. In fact, it is roughly the size of a credit card. Don’t be fooled by its size; as we know, good things come in small packages. However, the Raspberry Pi does not come in a package at all. It does not come in a case (although you can build one, as discussed in Adventure 1) and its circuit board and chips are fully visible, as you can see in Figure 1. You can plug a Raspberry Pi into a digital TV or monitor and use a USB keyboard and mouse with it, making it very easy to use, and because of its size you can easily transport it anywhere.

      The Raspberry Pi gives you the opportunity to build and control a device that does what you want it to do. For example, you can deploy your very own robot arm, controlled by a program that you have written. You can design and create your own role-playing game, or produce beautiful computer art or music, all by using code.

      Just because the Raspberry Pi is small doesn’t mean you can’t do big things with it. Here are just a few examples of some incredible Pi projects:

      ● Launching teddy bears into space using high altitude ballooning (www.raspberrypi.org/archives/4715)

      ● The ultimate bird feeder – it’s solar-powered, takes photographs and tweets images of birds! (www.raspberrypi.org/archives/4832)

      ● Crazy customised Halloween costumes like Doc Brown from Back to the Future (www.raspberrypi.org/archives/4856)

      ● A robotic sailboat (www.raspberrypi.org/archives/4109)

      ● Pi-controlled sculptures like the 15-foot tall Mens Amplio with a brain that lights up ( Скачать книгу
