Ready-to-use devices and self-built Arduino nodes in the 'The Things Network' LoRaWAN has developed excellently as a communication solution in the IoT. The Things Network (TTN) has contributed to this. The Things Network was upgraded to The Things Stack Community Edition (TTS (CE)). The TTN V2 clusters were closed towards the end of 2021. This book shows you the necessary steps to operate LoRaWAN nodes using TTS (CE) and maybe extend the network of gateways with an own gateway. Meanwhile, there are even LoRaWAN gateways suitable for mobile use with which you can connect to the TTN server via your cell phone. The author presents several commercial LoRaWAN nodes and new, low-cost and battery-powered hardware for building autonomous LoRaWAN nodes. Registering LoRaWAN nodes and gateways in the TTS (CE), providing the collected data via MQTT and visualization via Node-RED, Cayenne, Thingspeak, and Datacake enable complex IoT projects and completely new applications at very low cost. This book will enable you to provide and visualize data collected with battery-powered sensors (LoRaWAN nodes) wirelessly on the Internet. You will learn the basics for smart city and IoT applications that enable, for example, the measurement of air quality, water levels, snow depths, the determination of free parking spaces (smart parking), and the intelligent control of street lighting (smart lighting), among others.

From SRPP and Mu-Follower to OTL Designs Tube amplifiers suffer from distortion. Fortunately, circuits such as the SRPP amplifier, mu-follower, and beta-follower produce minimal distortion even at output voltages of 50 to 100 Vpeak. These designs are often published with errors. Without a sound understanding of the theory, it is easy to arrive at a flawed design. In the first section of this book, we investigate the origin of distortion, while in the second we investigate the design of and SRPP and a mu-follower. On the internet we can find the most exotic designs. Evaluating them teaches us that these designs often make matters worse rather than better. In the chapter on incorrect SRPPs and mu-followers, we sometimes see bizarre and misguided designs where using a simple single-triode amplifier would perform much better. Push-pull output stages also exist. A great number of them are examined, and their similarity to the SRPP is discussed. This is done especially with the help of the theory behind the OTL based on the ‘mother’ of all OTLs, the Philips HF303. Finally, attention is given to frequency characteristics and technical matters such as the supply voltage and the filament power supply. To illustrate these points, there are a few designs covering the subjects discussed. This book presents much new theory that has not been published before. It is often an eye-opener, showing that many things have a beautiful and unexpected simplicity.

Sound Secrets and Technology What would today’s rock and pop music be without electric lead and bass guitars? These instruments have been setting the tone for more than sixty years. Their underlying sound is determined largely by their electrical components. But, how do they actually work? Almost no one is able to explain this to the true musician with no technical background. This book answers many questions simply, in an easily-understandable manner. For the interested musician (and others), this book unveils, in a simple and well-grounded way, what have, until now, been regarded as manufacturer secrets. The examination explores deep within the guitar, including pickups and electrical environment, so that guitar electronics are no longer considered highly secret. With a few deft interventions, many instruments can be rendered more versatile and made to sound a lot better – in the most cost-effective manner. The author is an experienced electronics professional and active musician. He has thoroughly tested everything described here, in practice.

Du détecteur à la radio définie par logiciel La technologie des radiofréquences (RF) est l'un des domaines qui permet encore de mettre en pratique ses propres idées. D'innombrables variantes de circuits avec des objectifs particuliers laissent place à des expériences et des projets significatifs. Beaucoup de choses ne sont tout simplement pas disponibles dans le commerce. Des radios à détecteur de cristal sans source d'alimentation propre, de simples récepteurs à tube avec une touche de nostalgie, les premières tentatives de réception de Software Defined Radio, des récepteurs spéciaux pour radioamateur, tout cela peut être réalisé avec peu d'effort et comme une parfaite introduction à l'électronique RF. Pendant longtemps, la construction radio a été le premier pas vers l’électronique. Il existe cependant d’autres moyens, notamment via les ordinateurs, les microcontrôleurs et le numérique. Cependant, les racines analogiques de l’électronique sont souvent négligées. La technologie radio élémentaire et les expériences faciles à réaliser sont particulièrement adaptées comme domaine d'apprentissage de l'électronique, car vous pouvez ici commencer par les bases les plus simples. Mais le lien avec la technologie numérique moderne est également évident, par exemple lorsqu'il s'agit de méthodes de réglage modernes telles que PLL et DDS ou de radios DSP modernes. Ce livre vise à donner un aperçu et à présenter une collection de projets RF simples. L'auteur souhaite vous aider à développer vos propres idées, à concevoir vos propres récepteurs et à les tester.

Here are the most significant improvements and features in KiCad 8, both over and under the hood: Modern user interface, completely redesigned from earlier versions Improved and customizable electrical and design rule checkers Theme editor allowing you to customize KiCad on your screen Ability to import projects from Eagle, CADSTART, and more Python scripting API Improved integrated SPICE circuit simulator Multi-sheet schematics Filters define selectable elements Enhanced interactive router helps you draw single tracks and differential pairs with precision New or enhanced tools to draw tracks, measure distances, tune track lengths, etc. Advanced interactive router Built-in bill of materials generator Realistic ray-tracing capable 3D viewer Customizable teardrops Plug-in manager for quick installation of themes, libraries and functionalities such as autorouters and BOM generators This book will teach you to use KiCad through a practical approach. It will help you become productive quickly and start designing your own boards. Example projects illustrate the basic features of KiCad, even if you have no prior knowledge of PCB design. The author describes the entire workflow from schematic entry to the intricacies of finalizing the files for PCB production and offers sound guidance on the process. Further full-fledged projects, of incremental difficulty, will be presented in a second book, together with a variety of advanced recipes.

Programming and Projects for the Minima and WiFi Based on the low-cost 8-bit ATmega328P processor, the Arduino Uno R3 board is likely to score as the most popular Arduino family member, and this workhorse has been with us for many years. Eleven years later, the long-overdue successor, the Arduino Uno R4, was released. It is built around a 48 MHz, 32-bit Arm Cortex-M4 microcontroller and provides significantly expanded SRAM and Flash memory. Additionally, a higher-precision ADC and a new DAC are added to the design. The Uno R4 board also supports the CAN Bus with an interface. Two versions of the board are available: Uno R4 Minima, and Uno R4 WiFi. This book is about using these new boards to develop many different and interesting projects with just a handful of parts and external modules. All projects described in the book have been fully tested on the Uno R4 Minima or the Uno R4 WiFi board, as appropriate. The project topics include the reading, control, and driving of many components and modules in the kit as well as on the relevant Uno R4 board, including LEDs 7-segment displays (using timer interrupts) LCDs Sensors RFID Reader 4x4 Keypad Real-time clock (RTC) Joystick 8×8 LED matrix Motors DAC (Digital-to-analog converter) LED matrix WiFi connectivity Serial UART CAN bus Infrared controller and receiver Simulators … all in creative and educational ways with the project operation and associated software explained in great detail.
