Aus der Reihe "Stromversorgung ohne Stress" (Band 4) Renaissance der linearen Stromversorgungen Mittlerweile gibt es fast nur noch Schaltnetzteile. Da diese rauschen und stören, sind sie nicht für alle Einsatzzwecke die beste Wahl. Ursache sind durch den Schaltbetrieb erzeugte Hochfrequenzschwingungen, die in die Netzleitung und die Umgebung strahlen. Lineare Netzteile liefern Gleichspannungen von höchster Qualität. Über Brummen und Rauschen braucht man sich wenig Sorgen zu machen. Auch der Aufbau ist im Vergleich zu Schaltnetzteilen unkritisch. Wenn man überhaupt von Nachteilen bei linearen Netzteilen sprechen kann, wäre nur das höhere Gewicht zu nennen. Lineare Stromversorgungen sind auch einfach zu verstehen, können aus Standard-Bauteilen aufgebaut werden, sind leicht zu modifizieren und reparaturfähig und damit nachhaltig. In diesem Buch geht es um den Entwurf und den Bau von linearen Stromversorgungssystemen für kleine und große Leistungen. Aber auch Randthemen wie die lineare Steuerung von Verbrauchern und Kompromissen aus Kombinationen von Schaltnetzteil und linearem Netzteil oder Hilfsschaltungen wie lineare Lasten sind Bestandteil des Buches. Bei dieser Gelegenheit gibt es ausreichend Raum für die Besprechung der Grundlagen, der technischen Details, der Fallstricke und von Tipps und Tricks.

Dit boek gaat over de Raspberry Pi, en over het programmeren in C. De programmeertaal C en het besturingssysteem Linux (Raspbian) passen uitstekend bij elkaar. Alles wat we nodig hebben om in C te programmeren wordt meegeleverd met het besturingssysteem van de Raspberry Pi. In dit boek leert u hoe C gebruikt wordt met de Raspberry Pi, en krijgt u een overzicht van de taal. WiringPi is een softwarebibliotheek voor de Raspberry Pi waarmee C hardware-uitbreidingen kan benaderen. Die bibliotheek wordt gebruikt om sensoren uit te lezen en om extra hardware aan te sturen. U gaat experimenteren met LED’s en schakelaars, met motoren, met geluid en met sensoren voor temperatuur, luchtdruk, en luchtvochtigheid. Met een Linux-systeem kunt u een webserver maken, inclusief interactieve websites met PHP en WiringPi. Daarom is ook een beknopt overzicht van HTML en PHP in het boek opgenomen. In de voorbeelden worden sensoren via het web uitgelezen en worden apparaten bestuurd. In het laatste voorbeeld wordt een temperatuurlogger gemaakt. Die meet elk kwartier de temperatuur. Een tabel met de meetwaarden kan via het web worden uitgelezen. Alle voorbeeldprogramma’s kunnen worden gedownload van de website van Elektor.

An Introduction to Circuit Simulation LTspice, developed by Analog Devices, is a powerful, fast, and free SPICE simulator, schematic capture, and waveform viewer with a large database of components supported by SPICE models from all over the world. Drawing a schematic in LTspice is easy and fast. Thanks to its powerful graphing features, you can visualize the voltages and currents in a circuit, and also the power consumption of its components and much more. This book is about learning to design and simulate electronic circuits using LTspice. Among others, the following topics are treated: DC and AC circuits Signal diodes and Zener diodes Transistor circuits including oscillators Thyristor/SCR, diac, and triac circuits Operational amplifier circuits including oscillators The 555 timer IC Filters Voltage regulators Optocouplers Waveform generation Digital logic simulation including the 74HC family SPICE modeling LTspice is a powerful electronic circuit simulation tool with many features and possibilities. Covering them all in detail is not possible in a book of this size. Therefore, this book presents the most common topics like DC and AC circuit analysis, parameter sweeping, transfer functions, oscillators, graphing, etc. Although this book is an introduction to LTspice, it covers most topics of interest to people engaged in electronic circuit simulation. The book is aimed at electronic/electrical engineers, students, teachers, and hobbyists. Many tested simulation examples are given in the book. Readers do not need to have any computer programming skills, but it will help if they are familiar with basic electronic circuit design and operation principles. Readers who want to dive deeper can find many detailed tutorials, articles, videos, design files, and SPICE circuit models on the Internet. All the simulation examples used in the book are available as files at the webpage of this book. Readers can use these example circuits for learning or modify them for their own applications.

A Project-Based Introduction to Microcontrollers and Drone Control A Practical Introduction to Embedded Systems with the ESP32 This book is intended for readers who are new to embedded systems and looking for a structured, example-driven way to begin. If you’ve explored general-purpose electronics or Arduino-based resources but found them too broad or lacking in practical application, this guide offers a more focused alternative. With a small, affordable set of components – such as LEDs, sensors, an OLED screen and a motion sensor – you’ll build and work with the same hardware setup throughout the book. This allows you to focus on learning and experimenting without constant reconfiguration. Topics include: Understanding and programming the ESP32 microcontroller Using the Arduino IDE to write and deploy code Exploring cyber-physical systems, culminating in basic drone control No prior experience with Arduino or embedded development is required. Each section includes hands-on examples and mini-projects designed to reinforce core concepts and encourage deeper exploration. By the end, you’ll be equipped not only to reproduce the book’s examples, but also to extend them toward your own ideas and applications. Whether your interest is in learning embedded programming, building interactive systems, or exploring educational drone control, this book provides a clear and practical path to getting started.

De mens is van nature uitgerust met sensoren voor geluid, licht, geur, smaak en gevoel. Zintuigen die met elektronica slechts ten dele gekopieerd kunnen worden. Met de Elektor sensorkit kunnen we wel aardig in de buurt komen. Sensoren kunnen elektronica aansturen, maar ze kunnen ons ook van informatie voorzien. Daarom vormt niet alleen het meten van grootheden, maar ook het zichtbaar maken ervan via de Arduino seriële monitor een niet onbelangrijk deel van dit boek. De microprocessor ATtiny85 die de Arduino-taal begrijpt, maakt het experimenteren met sensoren gemakkelijk en goedkoop. We zullen niet snel een Arduino-kaartje vast solderen in een permanente opstelling. Bij een achtpotige ATtiny zal dat geen schuldgevoel opleveren. Dat neemt niet weg dat alle sketches gewoon op elk Arduino-board draaien met mogelijk hier en daar een aanpassing van pennummers omdat die kunnen verschillen met reguliere Arduino-boards. We zullen uitgebreid aandacht besteden aan het programmeren van de ATtiny. Veel schakelingen zijn bruikbaar in het natuurkundepracticum op school of voor bedrijfsmatige toepassingen. Maar de nadruk ligt toch wel op de (beginnende) elektronicahobbyist die zijn vrije tijd op een leuke maar vooral ook nuttige manier wil besteden. Want meer dan ooit tevoren heeft techniek de toekomst.
