Computer-controlled production has also become indispensable in model making. Not only industrial manufacturers, but also more and more model makers themselves are using CNC-controlled machines to produce parts. In this book, Christoph Selig initiates you into the secrets of CNC milling and - for the first time – CNC turning. He comprehensively covers the hardware, the software, and the machine tools. The subject is the basics, but above all the practice of conversion and CNC-controlled manufacturing, so that the reader gets a complete insight into this fascinating technology, which in some cases revolutionises model making. From the content: • Why CNC technology for the hobby sector? • Axis drives • The control types • Stepper motors • Construction and operation of the stepper motor control SRS 1X035 • The Mach3 control software • Useful accessories • The practice • Generating the CNC programme • Generating G-code from DXF or HPGL • From the idea to the finished part • Milling technology • Turning technology • Practical examples Milling • Practical example turning • The CNC milling machine as a drawing machine • Manual GCode programming

NATIONAL BESTSELLER • Discover the game-changing theory of the cycles of history and what past generations can teach us about living through times of upheaval—with deep insights into the roles that Boomers, Generation X, and Millennials have to play—now with a new preface by Neil Howe. First comes a High, a period of confident expansion. Next comes an Awakening, a time of spiritual exploration and rebellion. Then comes an Unraveling, in which individualism triumphs over crumbling institutions. Last comes a Crisis—the Fourth Turning—when society passes through a great and perilous gate in history. William Strauss and Neil Howe will change the way you see the world—and your place in it. With blazing originality, The Fourth Turning illuminates the past, explains the present, and reimagines the future. Most remarkably, it offers an utterly persuasive prophecy about how America’s past will predict what comes next. Strauss and Howe base this vision on a provocative theory of American history. The authors look back five hundred years and uncover a distinct pattern: Modern history moves in cycles, each one lasting about the length of a long human life, each composed of four twenty-year eras—or “turnings”—that comprise history’s seasonal rhythm of growth, maturation, entropy, and rebirth. Illustrating this cycle through a brilliant analysis of the post–World War II period, The Fourth Turning offers bold predictions about how all of us can prepare, individually and collectively, for this rendezvous with destiny.

The small but growing body of information about auditory processes in infancy is a tribute to the ingenuity and persistence of investigators in this realm. Undeter red by the frequent expressions of boredom, rage, and indifference in their subjects, these investigators nevertheless continue to seek answers to the intrigu ing but difficult questions about the course of auditory development. In the spring of 1981, a group of leading scholars and researchers in audi tion gathered to discuss the topic, Auditory Development in Infancy, at the 11th annual psychology symposium at Erindale College, University of Toronto. They came from both sides of the Atlantic and from various disciplines, including audiology, neurology, physics, and psychology. They shared their views on theory and data, as well as their perspectives from the laboratory and clinic. One unexpected bonus was an unusually distinguished audience of researchers and clinicians who contributed to lively discussion within and beyond the formal sessions.

Do you know how to say “shovel” in Albanian? “Lopata”! Even if you don’t know how to say it in Albanian, be sure to throw one in the car when you go, or better yet take two and make sure they’re really solid ones. Albania has changed dramatically since my first visit in 1999. The towns have been renovated and new main roads, new bridges as well as a new highway to the north have been built. You can catch a mobile phone signal almost everywhere and the stores are full of goods. Only the mountains have remained the same – or maybe they have become even more desolate as time goes by. Young people are moving to the towns, mountain villages are depopulating and no one maintains the mountain roads. Illegal lumberjacks use IFA trucks to haul wood and the condition of the roads is getting worse and worse. Deep ruts, which are impassable with a regular off-road vehicle, are common. Roads are often washed away by water or covered by landslides. Each year after winter, more and more mountain roads are impassable. But there are still many beautiful, passable routes that lead to the most beautiful places in the mountains. The viewpoints of magnificent mountain lakes and majestic rock formations take your breath away. I would like this guide to lead you through the most beautiful places in Albania, places that I have fallen in love with and that I like to visit again and again. Don’t believe ugly stories that people in Central Europe tell to scare each other. Forget the legends about bloody vendettas and hold-ups. All the same, you can never be too careful and you’ll be wise to camp close to residential areas and greet and chat with the locals when you arrive. You might even bring them a small gift, like beer, a knife, an axe or cigarettes for adults and chocolate, coloured pencils, colouring books or English children’s books for kids. Albanians are very hospitable; I have always been polite and respectful to them and they have been very kind in return.
