  • From Rubbing Amber to Swiping Glass - Elektor

    Elektor Publishing How Humanity Turned Electricity into Electronics

    From Rubbing Amber to Swiping Glass "The story of electricity, told one connection at a time."Why does rubbing amber attract dust? How did we go from that curious effect to a world where screens respond to a single touch? And how did we get from mysterious sparks to tiny chips packed with billions of transistors? For centuries, electricity puzzled and fascinated those who encountered its curious effects—long before it even had a name. From the earliest observations of static charge to the complex electronics that shape our lives today, this book traces the gradual, and often surprising, story of how humanity came to understand and harness this powerful force. This book offers an engaging and accessible account of the people, ideas, and inventions that transformed electricity from a scientific curiosity into the foundation of our digital age. Along the way, you’ll meet a host of inquisitive minds—some famous, others less so—whose persistence and creativity helped unravel the mysteries of the natural world and gave rise to the technologies we now take for granted. Covering everything from Leyden jars and batteries to transistors, microcontrollers and the internet, this book presents a clear and enjoyable overview of electronics and its relatively short, yet rich, history. Whether you have a technical background or simply a curiosity about how things work, From Rubbing Amber to Swiping Glass offers a thoughtful look at how far we’ve come—and a gentle nudge to wonder what might come next.

  • Raspberry Pi 4 OR 5 AND Pico (E - book) - Elektor

    Elektor Digital Raspberry Pi 4 OR 5 AND Pico (E-book)

    Cool Projects for Test, Measurement, and Control The Raspberry Pi has dominated the maker scene for many years. Freely accessible I/O pins have made it one of the most popular processor boards of all time. However, the classic Raspberry Pi has no analog inputs. Direct measurement of analog values is therefore not possible. Consequently, photodiodes, NTCs, Hall sensors, etc. cannot be read directly. In addition, the pins are connected directly to the exposed contacts, i.e. without a driver or protection circuit. This can quickly destroy the central controller and thus the entire Raspberry Pi. These problems can be elegantly solved with the Pico. As a front-end, it can easily handle a wide range of measurement tasks. In addition, the Pico is much cheaper than a classic Raspberry Pi 4 or 5. If a faulty circuit leads to the destruction of the Pico, this is relatively easy to handle. This makes the combination of a classic Raspberry Pi 4 or 5 and the Pico an ideal pair. The book introduces the broad and highly topical field of modern controller technology using the combined force of a Raspberry Pi 4 or 5 and a Raspberry Pi Pico. In addition to a detailed introduction to the operation and functionality of the controller boards themselves, the book also focuses on data acquisition and processing with digital processors. Especially the combination of both systems offers a wide range of interesting possibilities. Some practical projects from the contents: USB between Raspberry Pi 4 or 5 and Pico I²C Communication and Pico as an I²C device Voltmeter and Computer Thermometer Pico W as a Web Server and WLAN Scanner Frequency Meters and Generators OLED Displays on Raspberry Pi 4 or 5 and Pico Energy Saving Monitor Which Astronauts are in Orbit?

  • Arduino & Co - Measure, Control, and Hack (E - book) - Elektor

    Elektor Digital Arduino & Co – Measure, Control, and Hack (E-book)

    Clever Tricks with ATmega328 Pro Mini Boards With a simple Pro Mini board and a few other components, projects that 20 or 30 years ago were unthinkable (or would have cost a small fortune) are realized easily and affordably in this book: From simple LED effects to a full battery charging and testing station that will put a rechargeable through its paces, there’s something for everyone. All the projects are based on the ATmega328 microcontroller, which offers endless measuring, switching, and control options with its 20 input and output lines. For example, with a 7-segment display and a few resistors, you can build a voltmeter or an NTC-based thermometer. The Arduino platform offers the perfect development environment for programming this range of boards. Besides these very practical projects, the book also provides the necessary knowledge for you to create projects based on your own ideas. How to measure, and what? Which transistor is suitable for switching a certain load? When is it better to use an IC? How do you switch mains voltage? Even LilyPad-based battery-operated projects are discussed in detail, as well as many different motors, from simple DC motors to stepper motors. Sensors are another exciting topic: For example, a simple infrared receiver that can give disused remote controls a new lease on life controlling your home, and a tiny component that can actually measure the difference in air pressure between floor and table height!

    Elektor Digital Renewable Energy at Home (E-book)

    A Hands-on Guide to Crafting Your Own Power Plant The book you are about to read provides a step-by-step guide for building a renewable energy power plant at home. Our goal was to make the book as practical as possible. The material is intended for immediate application with a small amount of theory. Yet, the theory is important as a foundation that saves time and effort by disabusing the readers of potential misconceptions. Specifically, upon having a firm understanding of photovoltaic physics, you will not be inclined to fruitlessly search for 90% efficient solar panels! We want our readers to be the “doers”. If the book gets covered in grime and some pages become torn while you are building your power plant – this is the best compliment to us. The book covers solar and wind energy. Also, a curious power source based on manure is discussed as well, giving the doers an opportunity to further develop the manure fuel cell. It is important to note that there are many companies offering installation of complete solar solutions. Upon installing the panels, the system is not owned by the customer. Therefore, there is no freedom for experimentation and optimization. Also, none can beat the cost of a DIY solution as well as the ultimate satisfaction. All that is written here is a result of us building a renewable energy solution in Southern California. As the book was completed, the energy began flowing!

  • Technical Modeling with OpenSCAD (E - book) - Elektor

    Elektor Digital Technical Modeling with OpenSCAD (E-book)

    Create Models for 3D Printing, CNC Milling, Process Communication and Documentation Engineers dread designing 3D models using traditional modeling software. OpenSCAD takes a refreshing and completely different approach. Create your models by arranging geometric solids in a JavaScript-like language, and use them with your 3D printer, CNC mill, or process communication. OpenSCAD differs from other design systems in that it uses programmatical modeling. Your model is made up of primitives that are invoked using a C-, Java- or Python-like language. This approach to model design is close to the “mechanical work” done in the real world and appeals to engineers and others who are not a member of the traditional creative class. OpenSCAD also provides a wide variety of comfort functions that break the 1:1 relationship between code and geometry. This book demonstrates the various features of the programming language using practical examples such as a replacement knob for a LeCroy oscilloscope, a wardrobe hanger, a container for soap dispensers, and various other real-life examples. Written by an engineer with over 15 years of experience, this book is intended for Linux and Windows users alike. If you have programming experience in any language, this book will have you producing practical three-dimensional objects in short order!
