  • Analogue Video (E-BOOK)

    Elektor Digital Analogue Video (E-BOOK)

    This e-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 e-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 e-book is for you!

  • Microcontroller Basics with PIC (E-book)

    Elektor Digital Microcontroller Basics with PIC (E-book)

    In this book the author presents all essential aspects of microcontroller programming, without overloading the reader with unnecessary or quasi-relevant bits of information. Having read the book, you should be able to understand as well as program, 8-bit microcontrollers. The introduction to microcontroller programming is worked out using microcontrollers from the PIC series. Not exactly state-of-the-art with just 8 bits, the PIC micro has the advantage of being easy to comprehend. It is offered in a DIP enclosure, widely available and not overly complex. The entire datasheet of the PIC micro is shorter by decades than the description of the architecture outlining the processor section of an advanced microcontroller. Simplicity has its advantages here. Having mastered the fundamental operation of a microcontroller, you can easily enter into the realms of advanced softcores later. Having placed assembly code as the executive programming language in the foreground in the first part of the book, the author reaches a deeper level with ‘C’ in the second part. Cheerfully alongside the official subject matter, the book presents tips & tricks, interesting measurement technology, practical aspects of microcontroller programming, as well as hands-on options for easier working, debugging and faultfinding.

  • Marvelous Magnetic Machines

    Marvelous Magnetic Machines

    Building Model Electric Motors from ScrapYou’re standing in front of an old card table in a driveway at a garage sale. On that table is a one-quart aluminum saucepan, a votive candle holder, pieces of some office machinery, and a wooden awards plaque. What do you see there? If you did not answer “a six-cylinder radial electromagnetic attraction motor,” then you need this book!H.P. Friedrichs (author of The Voice of the Crystal and Instruments of Amplification) returns this time to explore the principles behind the operation and construction of five simple, yet impressive, model electric motors.Aspiring mechanical model makers are often discouraged by their lack of access to machine tools, like mills, lathes, or drill presses. Friedrichs demonstrates that with some basic knowledge, an open eye, and a sharp mind, one can use commonly available (and often discarded) parts and materials to engineer one’s way around any lack of expensive machine tooling. In fact, every motor in this book was built from scrap, and can be assembled with hand tools.You’ll learn where to hunt for and find materials, and where to salvage suitable bearings. You’ll know where useful solenoids can be extracted from scrap, and how to fabricate bobbins to wind your own. You’ll learn how to time your motors, fashion a connecting rod, make a commutator from scratch, use a hall effect sensor to detect magnet position, use a transistor as a switch, and much more.About the authorH.P. Friedrichs is a degreed electrical engineer (BSEE), inventor, and author with more than three decades of experience working in domains ranging from audio, medical, and radio, to software, automotive, and aerospace. At present, he is a Principal Engineer with Honeywell, involved in the design and support of specialized equipment used for testing and validating aircraft power generation products.He has five U.S. patents to his credit and holds three radio licenses including Extra-Class Amateur (AC7ZL), Commercial Radio Operator with Radar Endorsement and GMDSSOperator/Maintainer with Radar Endorsement. He is also a certified VE.Friedrichs is the author of numerous technical articles appearing in a variety of magazines, newsletters, and web sites but is best known for his books The Voice of the Crystal and Instruments of Amplification. Now cult classics among 'from-scratch' electronics experimenters, these books have enjoyed favorable reviews from the editors of such prestigious periodicals as QST, CQ Magazine, Practical Wireless, and Make Magazine.H.P. Friedrichs lives in Tucson, Arizona, with his wife and his German Shepherd/laboratory assistant — who is prone to 'borrow' books and tools but not return them.

  • Retronics (EN) | E-book

    Elektor Digital Retronics (EN) | E-book

    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 e-book (pdf)  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 e-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 e-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 e-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.

  • The State of Hollow State Audio (E-book)

    Elektor Digital The State of Hollow State Audio (E-book)

    The State of Hollow State Audio in the Second Decade of the 21st Century Vacuum-tube (or valve, depending upon which side of the pond you live on) technology spawned the Age of Electronics early in the 20th Century. Until the advent of solid-state electronics near mid-century, hollow-state devices were the only choice. But following the invention of the transistor (after their process fell to reasonable levels), within a couple of decades, the death of vacuum tubes was widely heralded. Yet here we are some five decades later, and hollow-state equipment is enjoying something of a comeback, especially in the music and high-end audio industries. Many issues surround hollow-state audio: Does it produce—as some claim—better sound? If so, is there science to back up these claims? How do hollow-state circuits work? How do you design hollow-state audio circuits? If hollow-state equipment fails, how do you go about troubleshooting and repairing it? Can we recreate some of the classic hollow-state audio devices for modern listening rooms and recording studios? How can we intelligently modify hollow-state amplifiers to our taste? These and other topics are covered in The State of Hollow State Audio.

  • ARM Microcontroller Projects  (E-BOOK)

    Elektor Digital ARM Microcontroller Projects (E-book)

    It is becoming important for microcontroller users to quickly learn and adapt to new technologies and architecture used in high performance 32-bit microcontrollers. Many manufacturers now offer 32-bit microcontrollers as general purpose processors in embedded applications. ARM provide 32 and 64-bit processors mainly for embedded applications. These days, the majority of mobile devices including mobile phones, tablets, and GPS receivers are based on ARM technology. The low cost, low power consumption, and high performance of ARM processors makes them ideal for use in complex communication and mixed signal applications. This e-book makes use of the ARM Cortex-M family of processors in easy-to-follow, practical projects. It gives a detailed introduction to the architecture of the Cortex-M family. Examples of popular hardware and software development kits are described. The architecture of the highly popular ARM Cortex-M processor STM32F107VCT6 is described at a high level, taking into consideration its clock mechanisms, general input/output ports, interrupt sources, ADC and DAC converters, timer facilities, and more. The information provided here should act as a basis for most readers to start using and programming the STM32F107VCT6 microcontroller together with a development kit. Furthermore, the use of the mikroC Pro for ARM integrated development environment (IDE) has been described in detail. This IDE includes everything required to create a project; namely an editor, compiler, simulator, debugger, and device programmer. Although the e-book is based on the STM32F107VCT6 microcontroller, readers should not find it difficult to follow the projects using other ARM processor family members. About the author Prof Dr Dogan Ibrahim has a BSc degree in electronic engineering, an MSc degree in automatic control engineering, and a PhD in digital signal processing.

  • Home Automation Projects with Arduino (E-BOOK)

    Elektor Digital Home Automation Projects with Arduino (E-BOOK)

    An Arduino board has now become ‘the’ basic component in the maker community. No longer is an introduction to the world of microcontrollers the preserve of the expert. When it comes to expanding the capabilities of the basic Arduino board however, the developer is still largely on his own. If you really want to build some innovative projects it’s often necessary to get down to component level. This can present many beginners with major problems. That is exactly where this e-book begins. This e-book explains how a wide variety of practical projects can be built using items supplied in a single kit together with the Arduino board. This kit, called the 'RFID Starter Kit for Arduino' (SKU 17240) is not just limited to RFID applications but contains more than 30 components, devices and modules covering all areas of modern electronics. In addition to more simple components such as LEDs and resistors there are also complex and sophisticated modules that employ the latest technology such as: A humidity sensor A multicolor LED A large LED matrix with 64 points of light A 4-character 7-segment LED display An infra red remote-controller unit A complete LC-display module A servo A stepper motor and controller module A complete RFID reader module and security tag On top of that you will get to build precise digital thermometers, hygrometers, exposure meters and various alarm systems. There are also practical devices and applications such as a fully automatic rain sensor, a sound-controlled remote control system, a multifunctional weather station and so much more. All of the projects described can be built using the components supplied in the Elektor kit.

  • Arduino in Control (3e versie) E-book

    Elektor Digital Arduino in Control (3e versie) E-book

    Physical Computing met het Arduino-platformDit leerboek over het Arduino-platform is uniek en brengt u stap voor stap van beginner tot gevorderde Arduino-gebruiker. Er wordt duidelijk in uitgelegd waarom en waardoor toepassingen werken, ondersteund door gedetailleerde afbeeldingen in kleur. Er is slechts een geringe elektronische basiskennis vereist, omdat de benodigde hardware uitgebreid wordt besproken. Het laatste gedeelte van dit boek bevat een degelijke theoretische verdieping, zodat u een krachtig naslagwerk achter de hand houdt.Er bestond in het Nederlands nog geen lesboek over dit platform. De didactische opbouw is zodanig dat de vereiste abstracte kennis wordt uitgelegd aan de hand van toepasbare en actuele praktijkvoorbeelden. De meeste toepassingen zijn gericht op ‘physical computing’, dat is de interactie tussen sensoren, actoren, elektronica en software. Hierdoor is het boek ook geschikt voor technisch beroepsonderwijs, o.a. voor de richting mechatronica.De opbouw van het boek is als volgt: Algemene introductie microcontrollers. Informatie over het Arduino-platform. Oefeningen met uitleg aan de hand van 21 voorbeelden. Praktijkvoorbeelden met uitleg aan de hand van 5 voorbeelden. Theoretische verdieping van de software en hardware. Praktische elektronicaschema´s. Alle software-voorbeelden in het boek zijn als download beschikbaar.Over de auteur:Marc Friedheim is docent aan de Leidse Instrumentmakers School, een school voor precisietechniek. Hij geeft daar o.a. les in ‘physical computing’. Hier leert hij zijn studenten hoe ze fijnmechanische constructies kunnen besturen en regelen d.m.v. embedded software, een combinatie van elektronica en software.
