Want to build your own satellite and launch it into space? It’s easier than you may think. The first in a series of four books, this do-it-yourself guide shows you the essential steps needed to design a base picosatellite platform—complete with a solar-powered computer-controlled assembly—tough enough to withstand a rocket launch and survive in orbit for three months. Whether you want to conduct scientific experiments, run engineering tests, or present an orbital art project, you’ll select basic components such as an antenna, radio transmitter, solar cells, battery, power bus, processor, sensors, and an extremely small picosatellite chassis. This entertaining series takes you through the entire process—from planning to launch. Prototype and fabricate printed circuit boards to handle your payload Choose a prefab satellite kit, complete with solar cells, power system, and on-board computer Calculate your power budget—how much you need vs. what the solar cells collect Select between the Arduino or BasicX-24 onboard processors, and determine how to use the radio transmitter and sensors Learn your launch options, including the providers and cost required Use milestones to keep your project schedule in motion

Radio spectrum for commanding and recording from our satellites is a shared resource with subtle hurdles. We walk the path originally paved by AMSATs to discuss the steps and licensing needed to set up and operate both a command uplink and a data download station and network. Find out how playing nicely with others maximizes your ability to get your data down.

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 circuits and Arduino programming. Use a special microphone and amplifier to build a reliable noise monitor Create a gadget to detect energy vampires: devices that use electricity when they’re “off” Examine water purity with a water conductivity device Measure weather basics such as temperature, humidity, and dew point Build your own Geiger counter to gauge background radiation Extend Arduino with an Ethernet shield—and put your data on the Internet Share your weather and radiation data online through Pachube

This book is an introduction to Cubesats, those popular and relatively inexpensive modular spacecraft that are upending the aerospace world. They have been built and deployed by colleges and Universities around the world, as well as high schools and elementary schools, even individuals. This is because Cubesats are modular, standard, and relatively low cost. The expensive part is the launch, but that is addressed by launch fixtures compatible with essentially ever launch on the planet. Although you may not have much of a choice in the orbit. Student Cubesat Projects are usually open source, may be world-wide in scope, and collaborative. At the same time, professionals in aerospace have not failed to consider the Cubesat architecture as an alternative for small-sat missions. This can reduce costs by one or two orders of magnitude. There are Cubesats on the International Space Station, and these can be returned to Earth on a resupply mission. There is a large "cottage industry' developed around the Cubesat architecture, addressing "professional" projects with space-rated hardware. NASA itself has developed Cubesat hardware (Pi-Sat) and Software (cfs). Cubesats are modular, built to a standard, and mostly open-source. The downside is, approximately 50% of Cubesat missions fail. We hope to point out some approaches to improve this. If you define and implement your own Cubesat mission, or work as a team member on a larger project, this book presents and points to information that will be valuable. Even if you never get your own Cubesat to orbit, you can be a valuable addition to a Cubesat or larger aerospace project. Shortly, two NASA Cubesats will be heading to Mars. The unique Cubesat architecture introduces a new Paradigm for exploring the many elements of our Solar System. Best of luck on your mission.

"A superb book.…Mearsheimer has made a significant contribution to our understanding of the behavior of great powers."—Barry R. Posen, The National Interest The updated edition of this classic treatise on the behavior of great powers takes a penetrating look at the question likely to dominate international relations in the twenty-first century: Can China rise peacefully? In clear, eloquent prose, John Mearsheimer explains why the answer is no: a rising China will seek to dominate Asia, while the United States, determined to remain the world's sole regional hegemon, will go to great lengths to prevent that from happening. The tragedy of great power politics is inescapable.

Equal accessibility to public places and services is now required by law in many countries. For the vision-impaired, specialised technology often can provide a fuller enjoyment of the facilities of society, from large scale meetings and public entertainments to reading a book or making music. This volume explores the engineering and design principles and techniques used in assistive technology for blind and vision-impaired people. This book maintains the currency of knowledge for engineers and health workers who develop devices and services for people with sight loss, and is an excellent source of reference for students of assistive technology and rehabilitation.
