Dit boek is bedoeld voor diegenen die zich bezig houden met geluidsversterking en geluidsdistributie. Het gaat in op de akoestische eigenschappen van open, halfopen en omsloten ruimten. Belangrijk is hoe luidsprekers aangepast kunnen worden op allerlei omgevingen. Meestal moet men een keuze maken uit het aanbod van luidsprekers en microfoons. De vraag is dan welke luidspreker en microfoon de juiste keuze zijn. En hoe deze moeten worden opgesteld waarbij spraak- en muziekverstaanbaarheid en de maximaal haalbare versterking in de live-situatie de belangrijkste criteria zijn. Dit boek geeft antwoord op die vragen. Verder wordt de lezer meegenomen naar het ontwerpen van luidsprekers op basis van de T/S parameters. Met eenvoudige software is het mogelijk akoestische en mechanische elementen van een luidspreker met de eventuele behuizing te vertalen naar de elektrische analogieën, zodat de luidspreker op de PC gesimuleerd kan worden. Aan de hand van rekenvoorbeelden worden bovenstaande simulaties ondersteund. Tot slot zijn in de referentielijst een aantal internetlinks opgenomen waaruit zeer waardevolle gegevens gehaald kunnen worden. De auteur, Peter Swarte, is natuurkundig ingenieur en was werkzaam bij Philips. Momenteel is hij_eigenaar van consultancy bureau P.A.S. Electro Acoustics en is hij actief lid van zowel het NAG (Nederlands Akoestisch Genootschap) als de AES (Audio Engineering Society).

If you can describe it, you can build it AI coding assistants are changing what makers and solopreneurs can build. Tasks that once demanded weeks of learning a new language, framework, or software stack can now be delegated to an AI—provided you know how to describe the job, judge the result, and keep control of the process. The Maker’s Guide to AI Coding is a practical guide to doing exactly that. It explains how to work with AI coding tools as collaborators rather than vending machines, how much to delegate, how to write specifications that produce useful results, and how to recognise hallucinations, context drift, overconfidence, and code that runs but is still wrong. The book is built around four increasingly ambitious projects. You begin with a browser-based RC filter analyser, then develop a live serial data plotter for Arduino and other microcontrollers. Next comes a datasheet questionand- answer tool using retrieval-augmented generation (RAG), followed by a complete multi-user resource booking system with authentication, a database, external services, background jobs, and deployment. No advanced programming background is required. The emphasis is on thinking clearly, guiding the AI, testing what it produces, and preserving the skills needed to evaluate its work. Along the way, you learn development workflow designed to remain useful as tools evolve. If you can describe what you want to build, this book shows you how to turn that description into working software.

All you need to know about good acoustics and sound systems in performance and worship spaces! Everyone knows that the ability to hear music in balance and to understand speech is essential in any space used for performance or worship. Unfortunately, in the early 21st century, we find that buildings with good acoustics are the exception rather than the rule. Much of the fault leading to this result can be traced to the widespread perception that acoustics is a black art. In fact, scientific acoustics as developed in the last century is a well-defined engineering practice that can lead to predictable excellent results. A basic, non-engineering understanding of acoustics will help building owners, theater managers, ministers and teachers of music, performers, and other professionals to achieve their goals of excellent acoustics in venues with which they work. Performers having a basic understanding of acoustics will be able to make the most of the acoustics of the venue in which they perform. This book helps those responsible for providing good acoustics in performance and worship spaces to understand the variables and choices entailed in proper acoustic design for performance and worship. Practicing acoustical consultants will find the book a useful reference as well. The level of presentation is comfortable and straightforward without being simplistic. If correct acoustical principles are incorporated into the design, renovation, and maintenance of performance and worship venues, good acoustics will be the result.

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.

Analogue Electronics and Microcontrollers Projects Hobbyist electronics can be a fun way to learn new skills that can be helpful to your career. Those who understand the basics of electronics can design their own circuits and projects. However, before you run, you need to learn to walk. It all starts with analogue electronics. You should be familiar with the simple components and circuits and understand their basic behaviors and the issues you may encounter. The best way to do this is through real experiments. Theory alone is not enough. This book offers a large number of practical entry-level circuits, with which everyone can gain the basic experience. Through the widespread introduction of microcontrollers, a new chapter in electronics has begun. Microcontrollers are now performing more and more tasks that were originally solved using discrete components and conventional ICs. Starting out has become easier and easier thanks to platforms including Bascom, Arduino, micro:bit. The book introduces numerous manageable microcontroller applications. It?s now a case of less soldering and more programming.

Nobody has any doubt that valve amplifiers produce a remarkably beautiful sound. They have a lively, deep, clear, and expressive sound, and dynamically they do not appear to have any limitations. The author investigates, in a systematic theoretical approach, the reasons for these beautiful properties. He develops new models for power valves and transformers, thus enabling the designer to determine the properties of the amplifier during the design process. Mathematical models for the coupling of power valve(s) and output transformer are provided. These will generate new insights in a special kind of distortion: the dynamic damping factor distortion (DDFD). With mathematical models in the complex domain, especially the properties at the limits of our hearing range (from 20 Hz to 20 kHz) are investigated and the minimal stability criteria for the amplifier are formulated. The often-applied negative feedback in amplifiers is extensively modelled and discussed in relation to our hearing appreciating. And after all this theory a fine selection of special amplifiers is presented and discussed. You will notice in this book that the author not only writes about amplifier technique, but tells about the way the development of valve amplifiers can have an influence on your daily life; even the usefulness of patents is discussed. Summarizing: new theories and solutions for perfect audio with valve amplifiers. Not only the professional and the DIY-er but everyone who wants to understand valve amplifiers will read this book with much pleasure.
