EAGLE – the “Easily Applicable Graphical Layout Editor“ is a professional-grade CAD (computer aided design) software package for the design and drafting of electronic schematics as well as the design and fabrication of printed circuit boards (PCBs). This Advanced User Guide provides the experienced EAGLE user with insight into using some of the more advanced features of EAGLE software. It is not a guide to teach the reader the basic concepts of EAGLE, nor does it discuss the ‘how to’ of the EAGLE interface and the simpler operations and commands of the software. That is the purpose of the author’s previous title EAGLE V6 Getting Started Guide also published by Elektor. This eBook is intended as an enduring document covering the more advanced modules, commands, and functions which make up EAGLE. It is hoped that this eBook will provide a quick, succinct reference to assist with more complex applications and uses of EAGLE – an ‘EAGLE User’s Companion’, if you like. Complementing the EAGLE Advanced User Guide, the EAGLE User Language manual is included in this eBook in unabridged form, reproduced with permission of CadSoft GmbH. At the time of writing, the material in this eBook covers version 7 of the EAGLE software suite.

This book is intended for electronics enthusiasts and professionals alike, who want a much deeper understanding of the incredible technology conquests over the pre-digital decades that created video. It details evolution of analogue video electronics and technology from the first electro-mechanical television, through advancements in Cathode Ray Tubes, transistor circuits and signal processing, up to the latest analogue, colour-rich TV, entertainment devices and calibration equipment. Key technological advances that enabled monochrome video and, eventually, colour are explained. The importance, compromises and techniques of maintaining crucial backward legacy compatibilities are described. The generation, signal processing and playback of analogue video signals in numerous capture, display, recording and playback devices together with operating principles and practices are examined. Technical and, often, political merits and deficiencies of key national and international video standards are highlighted. Several formats are shown to win and ultimately to co-exist. This book begins at fairly basic levels; concepts are introduced with human physiological perceptions of light and colour explained. This leads to the subject matter of luminance and chrominance; their equations and the circuits to process. There is full, detailed analysis of waveform shapes and timings inside video equipment and relevant popular connections e.g. S-video. Several analogue video projects which you can build yourself are also included in this book; with schematics, circuit board layouts and calibration steps to help you obtain the best results. The book makes use of many colour pages where the subject matter demands it (e.g. test cards). If you really want a deeper understanding of analogue video then this book is for you!

Quite unintentionally a one-page story on an old Heathkit tube tester in the December 2004 edition of Elektor magazine spawned dozens of ‘Retronics’ tales appearing with a monthly cadence, and attracting a steady flow of reader feedback and contributions to the series. Since launching his Retronics columns, Elektor Editor Jan Buiting has never been short of copy to print, or vintage equipment to marvel at. This book is a compilation of about 80 Retronics installments published between 2004 and 2012. The stories cover vintage test equipment, prehistoric computers, long forgotten components, and Elektor blockbuster projects, all aiming to make engineers smile, sit up, object, drool, or experience a whiff of nostalgia. To reflect that our memories are constantly playing tricks on us, and honoring that “one man’s rubbish is another man’s gem”, the tales in the book purposely have no chronological order, and no bias in favor of transistor or tube, microprocessor or discrete part, audio or RF, DIY or professional, dry or narrative style. Although vastly diff erent in subject matter, all tales in the book are told with personal gusto because Retronics is about sentiment in electronics engineering, construction and repair, be it to reminisce about a 1960s Tektronix scope with a cleaning lady as a feature, or a 1928 PanSanitor box for dubious medical use. Owners of this book are advised to not exceed one Retronics tale per working day, preferably consumed in the evening hours under lamp light, in a comfortable chair, with a piece of vintage electronic equipment close and powered up.

A Small Basic Approach There are many different PC programming languages available on the market. Some have beautiful names; some have easy to use development tools. Others have incredible power. They all have one thing in common: they assume that you have, or want to have, a knack for technology and difficult to read commands. In this book we take a practical approach to programming. We assume that you simply want to write a PC program, and write it quickly. Not in a professional environment, not in order to start a new career, but for plain and simple fun... or just to get a task done. Therefore we use Small Basic. You will have an application up and running in a matter of minutes. You will understand exactly how it works and be able to write text programs, graphical user interfaces, and advanced drivers. It is so simple; you don't even need to be an adult!

Electronic devices increasingly come with glued displays and batteries. And while the adhesive seal serves as a protection against dirt and water, it complicates the opening procedure of the device and hence its repair. The iOpener: Warm it through, unstick the glue! With the help of our iOpener, you can easily and quickly loosen adhesive without risking damage to your device due to overheating with a heat gun. Originally designed for opening Apple iPads, the iOpener is just as suitable for Samsung tablets, Sony smartphones, and devices from any other manufacturer who prefers adhesive over screws. How it works Heat the iOpener and place it on your device: Simply heat up the iOpener in the microwave or a pot of boiling water and position it on the edge of your device. The heat will soften the adhesive without damaging your gadget so you can insert an opening pick between the display and the case. Repeat this procedure for all glued areas, the iOpener is reusable any number of times. Use opening tools to remove adhesive residue: With the right tools, you’re now ready to open your device without hassle. The opening picks are sharp-edged enough to cut through the adhesive strips. Complete the opening procedure by prying up the case with an opening tool or lift your display with a suction cup or an iSclack. A must-have for electronic repairs The most annoying part of your repair is done, the rest will be almost a cinch. Whether you are a beginner or a professional, the iOpener should be part and parcel of every toolbox worthy of its name.

If you enjoy DIY electronics, projects, software and robots, you’ll find this book intellectually stimulating and immediately useful. With the right parts and a little guidance, you can build robot systems that suit your needs more than overpriced commercial systems can. 20 years ago, robots based on simple 8-bit processors and touch sensors were the norm. Now, it’s possible to build multi-core robots that can react to their surroundings with intelligence. Today’s robots combine sensor readings from accelerometers, gyroscopes and computer vision sensors to learn about their environments. They can respond using sophisticated control algorithms and they can process data both locally and in the cloud. This book, which covers the theory and best practices associated with advanced robot technologies, was written to help roboticists, whether amateur hobbyist or professional, take their designs to the next level. As will be seen, building advanced applications does not require extremely costly robot technology. All that is needed is simply the knowledge of which technologies are out there and how best to use each of them. Each chapter in this book will introduce one of these different technologies and discuss how best to use it in a robotics application. On the hardware side, we’ll cover microcontrollers, servos, and sensors, hopefully inspiring you to design your own awe-inspiring, next-generation systems. On the software side, we’ll cover programming languages, debugging, algorithms, and state machines. We’ll focus on the Arduino, the Parallax Propeller, Revolution Education PICAXE and projects I’ve with which I’ve been involved, including the TBot educational robot, the PropScope oscilloscope, the 12Blocks visual programming language, and the ViewPort development environment. In addition, we’ll serve up a comprehensive introduction to a variety of essential topics, including output (e.g. LEDs, servo motors), and communication technologies (e.g. infrared, audio), that you can use to develop systems that interact to stimuli and communicate with humans and other robots. To make these topics as accessible as possible, handy schematics, sample code and practical tips regarding building and debugging have been included. Hanno Sander Christchurch, New Zealand
