Elektor Publishing Building Wireless Sensor Networks with OpenThread
Developing CoAP applications for Thread networks with Zephyr This book will guide you through the operation of Thread, the setup of a Thread network, and the creation of your own Zephyr-based OpenThread applications to use it. You’ll acquire knowledge on: The capture of network packets on Thread networks using Wireshark and the nRF Sniffer for 802.15.4. Network simulation with the OpenThread Network Simulator. Connecting a Thread network to a non-Thread network using a Thread Border Router. The basics of Thread networking, including device roles and types, as well as the diverse types of unicast and multicast IPv6 addresses used in a Thread network. The mechanisms behind network discovery, DNS queries, NAT64, and multicast addresses. The process of joining a Thread network using network commissioning. CoAP servers and clients and their OpenThread API. Service registration and discovery. Securing CoAP messages with DTLS, using a pre-shared key or X.509 certificates. Investigating and optimizing a Thread device’s power consumption. Once you‘ve set up a Thread network with some devices and tried connecting and disconnecting them, you’ll have gained a good insight into the functionality of a Thread network, including its self-healing capabilities. After you’ve experimented with all code examples in this book, you’ll also have gained useful programming experience using the OpenThread API and CoAP.

Elektor Special: Solar Power Systems and Photovoltaics
As demand for solar panel installation has risen sharply, especially for installations larger than balcony power plants, the order books of solar companies are full. If you ask for a quote today, you may have to wait a while, if your request isn't simply postponed indefinitely. Another consequence of the solar boom is that some companies are charging very high prices for installations. Yet there is an obvious and radical solution to the problem of excessive prices: Do it yourself, as the English say. The price of materials is currently affordable, and it's the ideal time for those who do the work themselves. They couldn't save more. Add to this the satisfaction of doing something useful, both economically and ecologically, and the pleasure of building yourself. In this special issue, you'll find a wide selection of Elektor assemblies, from solar panel controllers to solar water heaters and solar panel orientation systems. The issue also contains practical information on solar panel installation and the technology behind them. Finally, there are a number of articles on the subject of balcony power plants, from how to install them to how to connect them to the Internet...

Elektor Digital Power Electronics in Motor Drives (E-book)
This book is for people who want to understand how AC drives (also known as inverter drives) work and how they are used in industry by showing mainly the practical design and application of drives. The key principles of power electronics are described and presented in a simple way, as are the basics of both DC and AC motors. The different parts of an AC drive are explained, together with the theoretical background and the practical design issues such as cooling and protection. An important part of the book gives details of the features and functions often found in AC drives and gives practical advice on how and where to use these. Also described is future drive technology, including a matrix inverter. The mathematics is kept to an essential minimum. Some basic understanding of mechanical and electrical theory is presumed, and a basic knowledge of single andthree phase AC systems would be useful. Anyone who uses or installs drives, or is just interested in how these powerful electronic products operate and control modern industry, will find this book fascinating and informative.

Elektor Digital Elektor Special: Power Supplies and Batteries (PDF)
Quelles que soient les méthodes ou même les moyens financiers dont vous disposez pour faire fonctionner vos circuits, l'alimentation électrique doit figurer en bonne place, voire numéro un, dans vos considérations. Le bloc de conception simplement appelé « alimentation » est extrêmement sous-estimé, tant dans la création que dans la réparation de produits électroniques. Pourtant, le « PSU » présente une énorme diversité et se présente sous des formes très différentes comme AC/DC, générateur, batterie (rechargeable ou non), panneau photovoltaïque, de table, linéaire ou à découpage, pour n'en citer que quelques-uns. Les plages de sortie sont également stupéfiantes, du nano-ampère au kiloampère et il en va de même pour les tensions. Ce spécial couvre les caractéristiques et les aspects de conception des alimentations. Contenu Les bases Gestion de la batterie Ce qu'il faut savoir lors de l'utilisation de piles (au lithium). Alimentation à tension fixe utilisant des régulateurs linéaires Le meilleur résultat juste après les piles. Récupération d'énergie lumineuse Un petit panneau solaire est utilisé dans un projet de récupération d'énergie pour gérer et charger quatre cellules AAA. Conception de l'adaptateur alimenté par secteur Circuits de base et conseils pour transformateurs, redressement, filtrage et stabilisation. Démarrage progressif LM317 L'impulsion de courant d'appel élevée doit être évitée.
