Technik + Sound Was wäre die heutige Rock- und Popmusik ohne Elektrogitarren und Elektrobässe? Diese Instrumente geben seit mehr als vierzig Jahren klar den Ton an. Ihr Sound wird zum großen Teil von den elektrischen Komponenten bestimmt. Doch wie funktionieren sie eigentlich? Kaum jemand ist in der Lage, diese Frage auch dem Vollblutmusiker ohne technischen Background verständlich zu beantworten. Dieses Buch beantwortet viele offene Fragen unkompliziert und in einer leicht verständlichen Art und Weise. Was bisher noch weitgehend als Herstellergeheimnis galt, entschleiert dieses Buch für jeden interessierten Musiker (auch für andere) in einer deutlichen und fundierten Art. Der Blick geht tief ins Innere der Gitarren bis in die Tonabnehmer (Pickups) und ihr elektrisches Umfeld. Damit ist die Gitarrenelektronik im Kern kein Buch mehr mit sieben Siegeln. Mit ein paar geschickten Eingriffen lassen sich viele Instrumente im Klang noch deutlich verbessern und vielseitiger machen – mit optimalem Verhältnis von investiertem Geld zu Nutzeffekt. Der Autor ist langjähriger Elektronik-Profi und aktiver Musiker. Was hier beschrieben ist, hat er alles selbst ausgiebig in der Praxis getestet.

Practical Applications and Project with Arduino, ESP32, and RP2040 Immerse yourself in the fascinating world of control engineering with Arduino and ESP32! This book offers you a practical introduction to classic and modern control methods, including PID controllers, fuzzy logic, and sliding-mode controllers. In the first part, you will learn the basics of the popular Arduino controllers, such as the Arduino Uno and the ESP32, as well as the integration of sensors for temperature and pH measurement (NTC, PT100, PT1000, and pH sensor). You will learn how to use these sensors in various projects and how to visualize data on a Nextion TFT display. The course continues with an introduction to actuators such as MOSFET switches, H-bridges, and solid-state relays, which are used to control motors and actuators. You will learn to analyze and model controlled systems, including PT1 and PT2 control. The book focuses on the implementation of fuzzy and PID controllers for controlling temperature and DC motors. Both the Arduino Uno and the ESP32 are used. The sliding-mode controller is also introduced. In the second-to-last chapter, you will explore the basics of neural networks and learn how machine learning can be used on an Arduino. In the last chapter, there is a practical example of a fuzzy controller for feeding electricity into the household grid. This book is the perfect choice for engineers, students, and electronics engineers who want to expand their projects with innovative control techniques.

For Raspberry Pi, ESP32 and nRF52 with Python, Arduino and Zephyr Bluetooth Low Energy (BLE) radio chips are ubiquitous from Raspberry Pi to light bulbs. BLE is an elaborate technology with a comprehensive specification, but the basics are quite accessible. A progressive and systematic approach will lead you far in mastering this wireless communication technique, which is essential for working in low power scenarios. In this book, you’ll learn how to: Discover BLE devices in the neighborhood by listening to their advertisements. Create your own BLE devices advertising data. Connect to BLE devices such as heart rate monitors and proximity reporters. Create secure connections to BLE devices with encryption and authentication. Understand BLE service and profile specifications and implement them. Reverse engineer a BLE device with a proprietary implementation and control it with your own software. Make your BLE devices use as little power as possible. This book shows you the ropes of BLE programming with Python and the Bleak library on a Raspberry Pi or PC, with C++ and NimBLE-Arduino on Espressif’s ESP32 development boards, and with C on one of the development boards supported by the Zephyr real-time operating system, such as Nordic Semiconductor's nRF52 boards. Starting with a very little amount of theory, you’ll develop code right from the beginning. After you’ve completed this book, you’ll know enough to create your own BLE applications.
