Building electronic projects that interact with the physical world is good fun. But when devices that you've built start to talk to each other, things really start to get interesting Through a series of simple projects, you'll learn how to get your creations to communicate with one another by forming networks of smart devices that carry on conversations with you and your environment. Whether you need to plug some sensors in your home to the Internet or create a device that can interact wirelessly with other creations, Making Things Talk explains exactly what you need.

This book is perfect for people with little technical training but a lot of interest. Maybe you're a science teacher who wants to show students how to monitor weather conditions at several locations at once, or a sculptor who wants to stage a room of choreographed mechanical sculptures. Making Things Talk demonstrates that once you figure out how objects communicate -- whether they're microcontroller-powered devices, email programs, or networked databases -- you can get them to interact.

Each chapter in contains instructions on how to build working projects that help you do just that. You will:

• Make your pet's bed send you email
• Make your own seesaw game controller that communicates over the Internet
• Learn how to use ZigBee and Bluetooth radios to transmit sensor data wirelessly
• Set up communication between microcontrollers, personal computers, and web servers using three easy-to-program, open source environments: Arduino/Wiring, Processing, and PHP.
• Write programs to send data across the Internet based on physical activity in your home, office, or backyard
• And much more

With a little electronics know-how, basic (not necessarily in BASIC) programming skills, a couple of inexpensive microcontroller kits and some network modules to make them communicate using Ethernet, ZigBee, and Bluetooth, you can get started on these projects right away. With Making Things Talk, the possibilities are practically endless..

"America had a secret weapon," writes Steve Call of the period immediately following September 11, 2001, as planners contemplated the invasion of Afghanistan This weapon consisted of small teams of Special Forces operatives trained in close air support (CAS) who, in cooperation with the loose federation of Afghan rebels opposed to the Taliban regime, soon began achieving impressive - and unexpected - military victories over Taliban forces and the al-Qaeda terrorists they had sponsored. The astounding success of CAS tactics coupled with ground operations in Afghanistan soon drew the attention of military decision makers and would eventually factor into the planning for another campaign: Operation Iraqi Freedom. But who, exactly, are these air power experts and what is the function of the TACPs (Tactical Air Control Parties) in which they operate? "Danger Close" provides a fascinating look at a dedicated, courageous, innovative, and often misunderstood and misused group of military professionals. Drawing on the gripping first-hand accounts of their battlefield experiences, Steve Call allows the TACPs to speak for themselves. He accompanies their narratives with informed analysis of the development of CAS strategy, including potentially controversial aspects of the interservice rivalries between the air force and the army which have at times complicated and even obstructed the optimal employment of TACP assets. "Danger Close" makes clear, however, that the systematic coordination of air power and ground forces played an invaluable supporting role in the initial military victories in both Afghanistan and Iraq. This first-ever examination of the intense, life-and-death world of the close air support specialist will introduce readers to a crucial but little-known aspect of contemporary warfare and add a needed chapter in American military history studies..

From rather humble beginnings as the Personal Home Page scripting language, PHP has found its way into almost every server, corporation, and dev shop in the world. On an average day, somewhere between 500,000 and 2 million coders do something in PHP. Even when you use a well-understood language like PHP, building a modern web application requires tools that decrease development time and cost while improving code quality. Frameworks such as Ruby-on-Rails and Django have been getting a lot of attention as a result.

For PHP coders, the Zend Framework offers that same promise without the need to move away from PHP. This powerful collection of components can be used in part or as a whole to speed up the development process. Zend Framework has the backing of Zend Technologies; the driving force behind the PHP programming language in which it is written. The first production release of the Zend Framework became available in July of 2007.

Zend Framework in Action is a comprehensive tutorial that shows how to use the Zend Framework to create web-based applications and web services. This book takes you on an over-the-shoulder tour of the components of the Zend Framework as you build a high quality, real-world web application. This book is organized around the techniques you'll use every day as a web developer "data handling, forms, authentication, and so forth. As you follow the running example, you'll learn to build interactive Ajax-driven features into your application without sacrificing nuts-and-bolts considerations like security and performance.

This book is aimed at the competent PHP developer who wants to master framework-driven web development. Zend Framework in Action goes beyond the docs but still provides quick access to the most common topics encountered in the development of web applications..
