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.

Ziehen Sie den Hebel nach unten, um die höchste Punktzahl zu erzielen!Dieser Elektor-Schaltungsklassiker aus dem Jahr 1984 zeigt eine spielerische Anwendung von Logik-ICs der CMOS-400x-Serie in Kombination mit LEDs, einer damals sehr beliebten Kombination. Das Projekt imitiert einen Spielautomaten mit rotierenden Ziffern.Das SpielUm das Spiel zu spielen, vereinbaren Sie zunächst die Anzahl der Runden. Spieler 1 betätigt den Schalthebel so lange wie gewünscht und lässt ihn los. Die LEDs zeigen dann die Punktzahl an, die sich aus der Summe der 50-20-10-5 aufleuchtenden Ziffern ergibt. Wenn die Play Again!-LED aufleuchtet, hat Spieler 1 eine weitere, „freie“ Runde. Wenn nicht, ist Spieler 2 am Zug. Die Spieler behalten ihre Punkte im Auge und der Spieler mit der höchsten Punktzahl gewinnt.FeaturesLEDs zeigen den Punktestand anMulti-Player und Play Again!Symbole des Elektor Heritage CircuitGetestet und geprüft von Elektor LabsEdukatives und geekiges ProjektNur Teile mit DurchgangslochLieferumfangPlatineAlle KomponentenHolzständerStücklisteWiderstände (5%, 250 mW)R1,R2,R3,R4 = 100kΩR5,R6,R7,R8,R9,R10 = 1kΩKondensatorenC1 = 4.7nF, 10%, 50V, 5mmC2 = 4.7μF, 10%, 63V, axialC3,C4 = 100nF, 10 %, 50V, Keramik X7R, 5mmHalbleiterLED1-LED6 = rot, 5mm (T1 3/4)IC1 = 74HC4024IC2 = 74HC132SonstigesS1 = Schalter, Kipphebel, 21-mm-Hebel, SPDT, tastendS2 = Schalter, taktil, 24V, 50mA, 6x6mmS3 = Schalter, Schieber, SPDTIC1,IC2 = IC-Sockel, DIP14BT1 = CR2032-Batteriehalteklammer für PlatinenmontageTischständerPCB 230098-1Nicht im Lieferumfang enthalten: BT1 = CR2032-Knopfzellenbatterie

A Practical Guide to Tube Electronics Vacuum tubes continue to exert a special fascination. Their long-lasting operation, robustness, and characteristic behavior fundamentally distinguish them from modern semiconductor technology. Despite their age, tubes are by no means merely historical components; they are still used today in audio technology, measurement technology, and especially in hobbyist applications. This book is aimed at electronics enthusiasts and hobbyists who want to not only learn about and understand vacuum tubes in theory, but also use them in practice. It conveys the fundamentals of tube technology, explains the different designs and designations, shows typical circuits, and addresses power supplies, measurements, and safety-related aspects. The focus is on practical explanations and realistic examples from the workshop. Numerous tips help you avoid typical mistakes, build circuits, and understand tube devices and their construction. Basic knowledge of electronics is assumed. Vacuum Tubes: A Practical Guide to Tube Electronics offers an accessible and thorough introduction to tube technology – factual, comprehensible, and with a clear focus on practical applications.

Modular and Scalable Control Systems Using Structured Text This book offers a structured and practical approach to modern PLC development using object-oriented principles. It is a guide for engineers, programmers, and students seeking to harness the power of object-oriented programming (OOP) in the context of industrial automation with PLCs. The content focuses on the CODESYS development environment and Structured Text (ST), both of which support modern programming techniques while maintaining compatibility with real-time automation requirements. Through step-by-step demos and instructional examples, it demonstrates how modular, reusable code can enhance development efficiency, simplify ongoing maintenance, and enable scalable and flexible control system architectures. Key topics include: Structured Text fundamentals: conditions, loops, arrays, and functions Object-oriented concepts: classes, methods, and inheritance Advanced techniques: polymorphism, interfaces, and access control Modular design with reusable components and structured program flow Implementation of finite state machines and scalable application design Built around instructional demos and clear explanations, this book helps readers develop maintainable and modern control software in the CODESYS environment using proven programming techniques.

The Basics, New Ideas & Applications Build digital electronics from the ground up—and take it all the way to practical circuits you can use. This book guides you through the core principles of digital technology with a strongly hands-on approach. You’ll begin with the essentials: signals, devices for working with them, and what "logic 0" and "logic 1" mean in real hardware. Simple demonstration setups made from easy-to-find parts (LEDs, diodes, resistors, switches) help you see how logic behaves, making the theory click before you move on. From there, you’ll explore a wide range of logic elements and how they’re implemented, including classic logic families such as TTL and CMOS. The fundamentals section covers the building blocks of digital systems: flip-flops, Schmitt triggers, registers, counters and dividers, encoders/ decoders, multiplexers/demultiplexers, plus A/D and D/A conversion and timing circuits. Next, the book invites you into "new ideas" in digital electronics—universal logic elements, unconventional approaches (including thyristor-based and fractional logic), and creative logic functions that can inspire original designs. Finally, a large, well-organized collection of application circuits turns knowledge into projects: electronic switches and selectors, pulse generators, PWM regulators, frequency multipliers/dividers, phase shifters, and digital filters. Study it deeply, and you’ll gain not only understanding—but the ability to design and debug digital circuits independently.
