Elektor Digital ESP8266 and MicroPython (E-book)
Recently, the development of a tiny chip called the ESP8266 has made it possible to interface any type of microcontroller to a Wi-Fi AP. The ESP8266 is a low-cost tiny Wi-Fi chip having fully built-in TCP/IP stack and a 32-bit microcontroller unit. This chip, produced by Shanghai based Chinese manufacturer Espressif System, is IEEE 802.11 b/g/n Wi-Fi compatible with on-chip program and data memory, and general purpose input-output ports. Several manufacturers have incorporated the ESP8266 chip in their hardware products (e.g. ESP-xx, NodeMCU etc) and offer these products as a means of connecting a microcontroller system such as the Android, PIC microcontroller or others to a Wi-Fi. The ESP8266 is a low-power chip and costs only a few Dollars. ESP8266 and MicroPython – Coding Cool Stuff is an introduction to the ESP8266 chip and describes the features of this chip and shows how various firmware and programming languages such as the MicroPython can be uploaded to the chip. The main aim of the book is to teach the readers how to use the MicroPython programming language on ESP8266 based hardware, especially on the NodeMCU. Several interesting and useful projects are given in the e-book (pdf) to show how to use the MicroPython in NodeMCU type ESP8266 hardware: Project “What shall I wear today?”: You will be developing a weather information system using a NodeMCU development board together with a Text-to-Speech processor module. Project “The Temperature and Humidity on the Cloud”: You will be developing a system that will get the ambient temperature and humidity using a sensor and then store this data on the cloud so that it can be accessed from anywhere. Project “Remote Web Based Control”: You will be developing a system that will remotely control two LEDs connected to a NodeMCU development board using an HTTP Web Server application.

Elektor Digital PC Programming (E-book)
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!

Elektor Digital Les installations domestiques à énergies renouvelables (PDF)
Les Accords de Kyoto, le réchauffement climatique, le Grenelle de l'environnement sont autant de termes devenus familles dans le cadre d'une réflexion éco-citoyenne collective. Au cours de la conversation, il est important de mener des actions concrètes et de veiller à ce que votre énergie soit renouvelable dans le cadre de votre maison individuelle. Les applications possibles sont légion : production électrique photovoltaïque, éolienne ou hydraulique, chauffe-eau solaire, chauffage des locaux par géothermie, par aérothermie ou par biomasse (bois-énergie). Pour répondre à cette demande croissante, une nouvelle filière connue ou développement fulgurant, mesurable à la création quasi quotidienne d'entreprises spécialisées. Les cellules sont immergées dans les techniques propositionnelles qui servent à les adapter, mais à cause de l'émanation de compétences professionnelles. Il est important de savoir évaluer les compétences des techniques avancées proposées par les métiers ; Pour que l’énergie soit renouvelable, la connaissance du vocabulaire, des principes de physique et des méthodes de dimensionnement des matériaux sont nécessaires. C'est la mission assignée à cet ouvrage.

Elektor Publishing Apple Macintosh
20+ Macintosh Models, from 1984 to Today (History, Engineering, and Restoration) Apple is not like any other company. More than anyone else, it transformed technology into something people could desire, love, and even identify with—much like a luxury brand. Users were not only buying a tool; they were buying a vision, a way of life. At the center of this transformation stands the Macintosh. First introduced in 1984, it was radically different from everything before. With its graphical interface and mouse, it made computing approachable, even friendly. What now feels obvious—clicking on icons, dragging files, pointing instead of typing commands—was revolutionary at the time. The Macintosh not only changed the way people related to technology. The Macintosh forced the entire industry to rethink the way we use computers. This book tells that story through some of the most significant Macintosh models. Each one is presented not only in words but also in images, because these computers are more than technology—they are design icons, symbols of a unique vision. History, technical detail, and photography come together here, aiming to show each Macintosh as it truly deserves to be seen.

Elektor Digital Funkempfänger-Kompendium (PDF)
Wollten Sie schon immer wissen, wie sich die klassische Funkempfängertechnik fortentwickelt hat? Wie funktionieren professionelle Funkempfänger heute und was können sie leisten? Wie ist es der modernen Funküberwachung und den Nachrichtendiensten möglich, gleich ganze Frequenzbänder in kürzester Zeit auszuforschen? Welche Empfangssysteme und Techniken stehen heute zur Verfügung? Möchten Sie auch ausgefallene Anwendungen von Empfängern kennenlernen und wissen, wie ein Software Defined Radio (Digitalempfänger) nun wirklich funktioniert und was der letzte Stand der entsprechenden Technik kann? Wodurch unterscheiden sich Kreuzmodulation und Intermodulation und worauf ist bei der messtechnischen Bestimmung und Datenblattvergleichen unbedingt zu achten? Warum folgen Intermodulationsprodukte nicht immer den Darstellungen von Lehrbüchern? Welche Artefakte zeigen digital nachgebildete Signalverarbeitungsketten abweichend von analogen Schaltungsstufen? Welche Auswirkungen haben derartige Kenngrößen tatsächlich auf die Empfangspraxis und warum kommt es nicht nur auf den IP3 an? Wie hängt beispielsweise die Grenzempfindlichkeit mit der Empfangsbandbreite zusammen? Was unterscheidet einen Signal/Rauschabstand nach der Beurteilung durch SINAD und (S+N)/N? Wie ist ein Empfangssystem zur Aufnahme kleinster Signalpegel zu optimieren? Fragen über Fragen – im vorliegenden Buch findet man die Antworten! Ausführlich und mit Details. Mit vielen speziell dafür erdachten Zeichnungen zur visuellen Erläuterung der Zusammenhänge. Mit durchgerechneten Fallbeispielen und dem stetigen Bezug zur Empfangspraxis. Großer Wert wurde den Darstellungen auf einheitliche Betrachtungsweise und durchgehende Systematik gelegt. Das erhöht die Übersichtlichkeit und erleichtert den Vergleich einzelner Vorgänge, Konzepte und Anlagen. Um den tatsächlichen Stand der Technik gut zu erfassen, wurden dutzende Patentschriften recherchiert und die Industrie mit eingebunden. Durch das sorgfältig aufbereitete Stichwortverzeichnis mit über 1200 Einträgen lassen sich die entsprechenden Stellen mit den Erklärungen rasch und punktgenau auffinden. Auch über die Thematik von Funkempfängern hinaus wird beim Studium der Lektüre vieles klar! Denn auch Messgeräte der Hochfrequenztechnik funktionieren vielmals nach ähnlichen Prinzipien. Wer den Inhalt durcharbeitet, kann wichtige Eigenschaften verstehen, beispielsweise von Spektrumanalysatoren und bei der Arbeit damit professionell vorgehen. Diese überarbeitete und erweiterte Neuauflage bringt erstmals sämtliche Bilder durchgehend in Vollfarbdruck, vertieft spezielle Themenschwerpunkte und bietet zusätzliche Fach- und Detailinformationen hinsichtlich den Realisierungsbeispielen gegenwärtiger Funkempfänger wie ferner durch das ergänzende Erörtern von jüngst verwendeten Messverfahren. Mit dem Erarbeiten und der Einbindung eines besonders umfangreichen, auf die Belange der heutigen Empfängertechnik zugeschnittenen Fach- und Übersetzungsglossars liegt zur Deutung entsprechender Fachbegriffe nunmehr eine Referenz vor.
