La technologie des ondes courtes présente un attrait particulier : elle peut facilement couvrir de grandes distances. En faisant rebondir les signaux à ondes courtes sur les couches conductrices de l’ionosphère, ils peuvent être reçus au-delà de l’horizon et ainsi atteindre n’importe où sur Terre. Bien que la technologie évolue vers des fréquences de plus en plus élevées et que la radio soit généralement écoutée sur FM, DAB+, satellite ou Internet, les méthodes de transmission modernes nécessitent une infrastructure étendue et sont extrêmement vulnérables. En cas de panne de courant mondiale, rien n’est plus important que les ondes courtes. La radio amateur n'est pas seulement un passe-temps, c'est aussi un système radio d'urgence ! Le SDR-Shield d'Elektor (SKU 18515) est un récepteur polyvalent à ondes courtes jusqu'à 30 MHz. À l'aide d'un Arduino et du logiciel approprié, les stations de radio, les signaux Morse, les stations SSB et les signaux numériques peuvent être reçus. Dans ce livre, l'auteur à succès et radioamateur enthousiaste Burkhard Kainka décrit la pratique moderne de la radio définie par logiciel utilisant le Shield SDR d'Elektor. Il fournit non seulement une formation théorique, mais explique également de nombreux outils logiciels open source.

A Combat Guide against E-waste and Throwawayism This book is for anyone who enjoys tinkering with analog and digital hardware electronics. Regardless of the sophistication of your workspace, only basic tools are required to achieve truly satisfying results. It is intended as a reference guide among other hardware repair publications you may have in your library. However, the book goes a step further than most other repair guides in addressing issues in the modern era of discarded electronics called e-waste. E-waste should be put to good use. Producing anything new requires not just precious resources and labor, but also energy to make and deliver it to global retail shelves. Your talents and love of electronics can be put to good use by rescuing and resurrecting at least selected units from this endless stream of e-waste. Examples include either restoring through repair, or salvaging reusable electronic and mechanical components for your next project. Smart tips are provided throughout the book, and much information is tabulated for easy reference. The book expands age-old repair and hacking techniques applied for repair on the workbench into clever methods and applications to achieve effective results with discarded or “non-servicable” electronic consumer products. The final chapter provides real-life examples using all of the previously discussed content in a summarized form for each example repair type.

Le multitâche et le multitraitement sont devenus un sujet très important dans les systèmes basés sur des microcontrôleurs, notamment dans les applications complexes d'automatisation commerciale, domestique et industrielle. À mesure que la complexité des projets augmente, davantage de fonctionnalités sont exigées des projets. De tels projets nécessitent l'utilisation de plusieurs tâches interdépendantes exécutées sur le même système et partageant les ressources disponibles, telles que le processeur, la mémoire et les ports d'entrée-sortie. En conséquence, l’importance des opérations multitâches dans les applications basées sur des microcontrôleurs n’a cessé de croître au cours des dernières années. De nombreux projets d'automatisation complexes utilisent désormais une forme de noyau multitâche. Ce livre est basé sur des projets et son objectif principal est d'enseigner les fonctionnalités de base du multitâche à l'aide du langage de programmation Python 3 sur Raspberry Pi. De nombreux projets entièrement testés sont fournis dans le livre utilisant les modules multitâches de Python. Chaque projet est décrit de manière complète et détaillée. Des listes complètes de programmes sont fournies pour chaque projet. Les lecteurs doivent pouvoir utiliser les projets tels quels ou les modifier en fonction de leurs propres besoins.

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!

Resonances From Aether Days A Pictorial and Technical Analysis from WWII to the Internet Age From the birth of radio to the late 1980s, much of real life unfolded through shortwave communication. World War II demonstrated—beyond a shadow of a doubt—that effective communications equipment was a vital prerequisite for military success. In the postwar years, shortwave became the backbone on which many of the world's most critical services depended every day. All the radio equipment—through whose cathodes, grids, plates, and transistors so much of human history has flowed—is an exceptional subject of study and enjoyment for those of us who are passionate about vintage electronics. In this book, which begins in the aftermath of World War II, you’ll find a rich collection of information: descriptions, tips, technical notes, photos, and schematics that will be valuable for anyone interested in restoring—or simply learning about—these extraordinary witnesses to one of the most remarkable eras in technological history. My hope is that these pages will help preserve this vast treasure of knowledge, innovation, and history—a heritage that far transcends the purely technical.

All you need to know about good acoustics and sound systems in performance and worship spaces! Everyone knows that the ability to hear music in balance and to understand speech is essential in any space used for performance or worship. Unfortunately, in the early 21st century, we find that buildings with good acoustics are the exception rather than the rule. Much of the fault leading to this result can be traced to the widespread perception that acoustics is a black art. In fact, scientific acoustics as developed in the last century is a well-defined engineering practice that can lead to predictable excellent results. A basic, non-engineering understanding of acoustics will help building owners, theater managers, ministers and teachers of music, performers, and other professionals to achieve their goals of excellent acoustics in venues with which they work. Performers having a basic understanding of acoustics will be able to make the most of the acoustics of the venue in which they perform. This book helps those responsible for providing good acoustics in performance and worship spaces to understand the variables and choices entailed in proper acoustic design for performance and worship. Practicing acoustical consultants will find the book a useful reference as well. The level of presentation is comfortable and straightforward without being simplistic. If correct acoustical principles are incorporated into the design, renovation, and maintenance of performance and worship venues, good acoustics will be the result.

Maîtriser le langage et la plateforme de développement Beaucoup de gens aimeraient apprendre Java mais se lancer n'est pas facile puisque programmer avec Java nécessite au moins deux choses : maîtriser le langage de programmation et l'environnement de développement. A l'aide de nombreux exemples, ce livre montre comment le langage est structuré. De plus, il utilise l'environnement de développement Eclipse comme exemple d'outil puissant pour enseigner le développement de programmes Java. Dans Basics, la première partie du livre, vous acquérez vos connaissances de base sur Java et Eclipse. Cette partie pose les bases de la programmation, vous donne un aperçu de la technologie Java et vous montre les particularités de la programmation orientée objet. Dans la deuxième partie intitulée Java Language, tout tourne autour des subtilités du langage Java et c'est là que sont créées les premières petites applications Java, aidées par un savant mélange de partie connaissances et d'exercices pratiques. La technologie Java est à la fois le nom et le thème de la troisième partie qui vous présente également les règles à respecter lors de la programmation, ce que sont les bibliothèques de classes et leurs avantages. De plus, vous apprendrez comment tester des programmes, ce que sont les algorithmes et comment les programmer. La quatrième partie, Projets Java, vous permet d'appliquer tous les éléments précédents dans une application avec une interface utilisateur graphique. Le projet montre comment développer une application plus grande pièce par pièce avec l'environnement de développement Eclipse. L'annexe se termine par une section sur les erreurs fréquentes pouvant survenir lors de l'utilisation d'Eclipse et un glossaire.
