Practical Introduction to 3D Modeling from Enclosure to Front Panel Embedding a vintage component, creating a professional looking home for a circuit board, or even designing a complex apparatus complete with a chassis – these and many other challenges turn into a stimulating pleasure with FreeCAD. Once you have internalized the basic processes, there are virtually no limits to your imagination. Starting to use a new software is never straightforward – especially with a tool as versatile as FreeCAD. Manageable, but at the same time easily usable individual components provide the starting point in this book. Putting these components together later results in assemblies. In the FreeCAD universe, a workable trajectory is demonstrated. The described procedure is illustrative so the examples are easily applied to custom tasks. The devices were made by the author and illustrated with photos. Creating a 3D design is requiring some effort but the initial investment pays off soon. Besides the impressive spatial representation of the projects, the extracted drawings yield a solid base for documentation and production. Extended FreeCAD capabilities like the unfolding of sheet metal parts enormously add to efficiency and pushes models forward into practical assembly.

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.

La plupart des gens sont de plus en plus confrontés aux applications de l’intelligence artificielle (IA). Les classements de musique ou de vidéo, les systèmes de navigation, les conseils d'achat, etc. reposent sur des méthodes qui peuvent être attribuées à ce domaine. Le terme intelligence artificielle a été inventé en 1956 lors d’une conférence internationale connue sous le nom de Dartmouth Summer Research Project. Une approche fondamentale consistait à modéliser le fonctionnement du cerveau humain et à construire des systèmes informatiques avancés sur cette base. Bientôt, le fonctionnement de l’esprit humain devrait être clair. Le transférer sur une machine n’était considéré qu’une petite étape. Cette notion s'est avérée un peu trop optimiste. Néanmoins, les progrès de l’IA moderne, ou plutôt de sa sous-spécialité appelée Machine Learning (ML), ne peuvent plus être niés. Dans ce livre, plusieurs systèmes différents seront utilisés pour connaître plus en détail les méthodes d’apprentissage automatique. En plus du PC, le Raspberry Pi et le Maixduino démontreront leurs capacités dans les différents projets. Outre des applications telles que la reconnaissance d'objets et de visages, des systèmes pratiques tels que des détecteurs de bouteilles, des compteurs de personnes ou un « œil qui parle » seront également créés. Ce dernier est capable de décrire acoustiquement des objets ou des visages détectés automatiquement. Par exemple, si un véhicule se trouve dans le champ de vision de la caméra connectée, l'information « Je vois une voiture ! est émis via une parole générée électroniquement. De tels appareils sont des exemples très intéressants de la manière dont, par exemple, les personnes aveugles ou gravement malvoyantes peuvent également bénéficier des systèmes d’IA.

Projects with Thonny-IDE, uPyCraft-IDE, and ESP32 The 'Python' programming language has enjoyed an enormous upswing in recent years. Not least, various single-board systems such as the Raspberry Pi have contributed to its popularity. But Python has also found widespread use in other fields, such as artificial intelligence (AI) or machine learning (ML). It is obvious, therefore, to use Python or the 'MicroPython' variant for use in SoCs (Systems on Chip) as well. Powerful controllers such as the ESP32 from Espressif Systems offer excellent performance as well as Wi-Fi and Bluetooth functionality at an affordable price. With these features, the Maker scene has been taken by storm. Compared to other controllers, the ESP32 has a significantly larger flash and SRAM memory, as well as a much higher CPU speed. Due to these characteristics, the chip is not only suitable for classic C applications, but also for programming with MicroPython. This book introduces the application of modern one-chip systems. In addition to the technical background, the focus is on MicroPython itself. After the introduction to the language, the programming skills learned are immediately put into practice. The individual projects are suitable for use in the laboratory as well as for everyday applications. So, in addition to the actual learning effect, the focus is also on the joy of building complete and useful devices. By using laboratory breadboards, circuits of all kinds can be realized with little effort, turning the testing and debugging of the 100% homebrew projects into an instructive pleasure. The various applications, such as weather stations, digital voltmeters, ultrasound range finders, RFID card readers or function generators, make the projects presented ideally suited for practical courses or subject and study work in the natural sciences, or in science and technology classes.

An 8-in-1 test & measurement instrument for the electronics workbench A well-equipped electronics lab is crammed with power supplies, measuring devices, test equipment and signal generators. Wouldn‘t it be better to have one compact device for almost all tasks? Based on the Arduino, a PC interface is to be developed that’s as versatile as possible for measurement and control. It simply hangs on a USB cable and – depending on the software – forms the measuring head of a digital voltmeter or PC oscilloscope, a signal generator, an adjustable voltage source, a frequency counter, an ohmmeter, a capacitance meter, a characteristic curve recorder, and much more. The circuits and methods collected here are not only relevant for exactly these tasks in the "MSR" electronics lab, but many details can also be used within completely different contexts.

Resonances From Aether Days A Pictorial and Technical Analysis from WWII to the Internet Age From the birth of radio to the late 1980s, much of real life unfolded through shortwave communication. World War II demonstrated—beyond a shadow of a doubt—that effective communications equipment was a vital prerequisite for military success. In the postwar years, shortwave became the backbone on which many of the world's most critical services depended every day. All the radio equipment—through whose cathodes, grids, plates, and transistors so much of human history has flowed—is an exceptional subject of study and enjoyment for those of us who are passionate about vintage electronics. In this book, which begins in the aftermath of World War II, you’ll find a rich collection of information: descriptions, tips, technical notes, photos, and schematics that will be valuable for anyone interested in restoring—or simply learning about—these extraordinary witnesses to one of the most remarkable eras in technological history. My hope is that these pages will help preserve this vast treasure of knowledge, innovation, and history—a heritage that far transcends the purely technical.
