Description

DIY hardware hacking...easy as Pi ®!

Raspberry Pi is taking off like a rocket! You can use this amazing, dirt-cheap, credit card-sized computer to learn powerful hardware hacking techniques as you build incredibly creative and useful projects! This complete, full-color guide requires absolutely no experience with either hardware hacking or computer programming. Colorful photos guide you through each project, and the step-by-step instructions are stunningly clear and easy!

1. Start with the absolute basics:

  • Discover why millions of people are so passionate about the Pi!
  • Tour the hardware, including storage, connections, and networking
  • Install and run Raspbian, Raspberry Pi’s Linux-based operating system
  • Manage devices and configuration files
  • Network Raspberry Pi and add Wi-Fi
  • Program Raspberry Pi using Python, Scratch, XHTML, PHP, and MySQL

2. Next, build all these great projects:

  • Media Center
  • Retro Console Video Game Station
  • Minecraft Server
  • Web Server
  • Portable Webcam
  • Security & Privacy Device

3. Then, master all these cutting-edge techniques:

  • Overclock Raspberry Pi for better performance
  • Link Raspberry Pi to the Arduino and Arduino clones, including the AlaMode and the Gertboard
  • Use the Pi to build electronics prototypes using a breadboard
