Makers around the globe are building low-cost devices to monitor the environment, and with this hands-on guide, so can you. Through succinct tutorials, illustrations, and clear step-by-step instructions, you’ll learn how to create gadgets for examining the quality of our atmosphere, using Arduino and several inexpensive sensors. Detect harmful gases, dust particles such as smoke and smog, and upper atmospheric haze—substances and conditions that are often invisible to your senses. You’ll also discover how to use the scientific method to help you learn even more from your atmospheric tests. Get up to speed on Arduino with a quick electronics primer Build a tropospheric gas sensor to det...
After the devastating tsunami in 2011, DYIers in Japan built their own devices to detect radiation levels, then posted their finding on the Internet. Right now, thousands of people worldwide are tracking environmental conditions with monitoring devices they’ve built themselves. You can do it too! This inspiring guide shows you how to use Arduino to create gadgets for measuring noise, weather, electromagnetic interference (EMI), water purity, and more. You’ll also learn how to collect and share your own data, and you can experiment by creating your own variations of the gadgets covered in the book. If you’re new to DIY electronics, the first chapter offers a primer on electronic circuit...
Based on his popular Wired magazine column What's Inside, Patrick Di Justo takes a hard and incredibly funny look at the shocking, disgusting, and often dumbfounding ingredients found in everyday products, from Cool Whip and Tide Pods to Spam and Play-Doh. What do a cup of coffee and cockroach pheromone have in common? How is Fix-A-Flat like sugarless gum? Is a Slim Jim meat stick really alive? If I Can't Believe It's Not Butter isn't butter, what is it? All of these pressing questions and more are answered in This Is What You Just Put In Your Mouth? Patrick shares the madcap stories of his extensive research, including tracking down a reclusive condiment heir, partnering with a cop to get his hands on heroin, and getting tight-lipped snack-food execs to talk. Along the way, he schools us on product histories, label decoding, and the highfalutin chemistry concepts behind everything from Midol to Hostess fruit pies. Packed with facts you're going to want to share immediately, this is infotainment at its best—and most fun!—it will leave you giving your shampoo the side-eye and Doritos a double take, and make you the know-it-all in line at the grocery store.

Beginning Sensor Networks with Arduino and Raspberry Pi teaches you how to build sensor networks with Arduino, Raspberry Pi, and XBee radio modules, and even shows you how to turn your Raspberry Pi into a MySQL database server to store your sensor data! First you'll learn about the different types of sensors and sensor networks, including how to build a simple XBee network. Then you'll walk through building an Arduino-based temperature sensor and data collector, followed by building a Raspberry Pi-based sensor node. Next you'll learn different ways to store sensor data, including writing to an SD card, sending data to the cloud, and setting up a Raspberry Pi MySQL server to host your data. You even learn how to connect to and interact with a MySQL database server directly from an Arduino! Finally you'll learn how to put it all together by connecting your Arduino sensor node to your new Raspberry Pi database server. If you want to see how well Arduino and Raspberry Pi can get along, especially to create a sensor network, then Beginning Sensor Networks with Arduino and Raspberry Pi is just the book you need.
It started with punk. Hip-hop, rave, graffiti, and gaming took it to another level, and now modern technology has made the ideas and innovations of youth culture increasingly intimate and increasingly global at the same time. In The Pirate's Dilemma, VICE magazine's Matt Mason -- poised to become the Malcolm Gladwell of the iPod Generation -- brings the exuberance of a passionate music fan and the technological savvy of an IT wizard to the task of sorting through the changes brought about by the interface of pop culture and innovation. He charts the rise of various youth movements -- from pirate radio to remix culture -- and tracks their ripple effect throughout larger society. Mason brings ...
