Selbst für so manchen an der Elektronik Interessierten ist die Röhrentechnologie ein technischer Anachronismus, Röhrenverstärkern könne doch allenfalls noch ein Ehrenplatz im Museum zugewiesen werden. Das ist einerseits durchaus richtig, Röhren haben eine fast hundertjährige Geschichte hinter sich. Seit der Erfindung des Transistors, der Öffentlichkeit vorgestellt am 23.12.1947, war das Ende der Röhrenära eingeläutet. Von da ab sollte es immerhin noch mehr als zwanzig Jahre dauern, bis die Röhren – von Sonderanwendungen abgesehen – aus dem Blickfeld des durchschnittlichen Elektronikgeräte-Konsumenten weitgehend verschwunden waren. So gesehen, sind Röhren tatsächlich veraltet, haben Röhren Museumcharakter. Niemand käme wohl heute auch mehr ernsthaft auf die Idee, sein leistungsfähiges Digitalmessinstrument gegen ein Röhrenvoltmeter auszutauschen; hochintegrierte Halbleiterchips können nun einmal bei eigentlich unvergleichlich geringerem Platz- und Energiebedarf mehr. Auf die Überlegenheit moderner Mikroprozessoren in Bezug auf Rechengeschwindigkeit und Speicherkapazität braucht man eigentlich gar nicht zu verweisen. Der erste programmgesteuerte Elektronikrechner Eniac im Jahre 1945 wog rund 30 Tonnen, enthielt neben insgesamt etwa 500.000 übrigen Bauteilen 18.000 Elektronenröhren und füllte eine mittlere Halle. In einem Bereich allerdings, im Bereich der Audio-Signalverarbeitung, haben Röhren bei Kennern und Musikliebhabern ihre Bedeutung bewahrt oder zurückerlangt: Für eine mittlerweile gestiegene Zahl kritischer Hi-Fi-Hörer steht "ihr" Röhrenverstärker im Zentrum der heimischen Anlage und für unzählige Musiker ist der Gitarrenröhrenverstärker nach wie vor ein Garant für guten Sound. Dieses Book spricht jeden an, der sich für Röhren aus den verschiedensten Gründen interessiert, den "Audiophilen" ebenso wie den aktiven Musiker und natürlich auch den, der einfach nur etwas über die Geschichte und die gegenwärtige Anwendbarkeit von Röhren wissen will. Aus diesem Grund hat der Autor sowohl Informationen über ein interessantes Stück Technikgeschichte als auch – praxisorientiert – Schaltungen und Selbstbauanleitungen zusammengetragen.

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.

STM32 Nucleo family of processors are manufactured by STMicroelectronics. These are low-cost ARM microcontroller development boards. This book is about developing projects using the popular Nucleo development board. In the early chapters of the book, the architecture of the Nucleo family is briefly described. Software development tools that can be used with the Nucleo boards such as the Mbed, Keil MDK, TrueSTUDIO, and the System Workbench are described briefly in later Chapters. The book covers many projects using most features of the STM32 Nucleo development boards where the full software listings for Mbed and System Workbench are given for every project. The projects range from simple flashing LEDs to more complex projects using modules and devices such as GPIO, ADC, DAC, I²C, LCD, analog inputs and others. In addition, several projects are given using the Nucleo Expansion Boards, including popular expansion boards such as solid-state relay, MEMS and environmental sensors, DC motor driver, Wi-Fi, and stepper motor driver. These Expansion Boards plug on top of the Nucleo development boards and simplify the task of project development considerably. Features of this book Learn the architecture of the STM32 microcontrollers Learn how to use the Nucleo development board in projects using Mbed and System Workbench Toolchains Learn how to use the Nucleo Expansion Boards with the Nucleo development boards Update The Mbed compiler has been replaced with two software packages: The Mbed Studio and Keil Studio Cloud. Both of these software packages are free of charge and are available on the Internet. If you need assistance using the Keil Studio Cloud, please download the Guide below.

Mastering the Language and the Development Platform Many people would like to learn Java but getting started is not easy since programming with Java requires at least two things: mastering the programming language and the development environment. With the help of many examples, this book shows how the language is structured. In addition, it employs the Eclipse development environment as an example of a powerful tool to teach developing Java programs. In Basics, the first part of the book, you acquire your Java and Eclipse basic knowledge. This part lays the programming foundations, gives you an overview of Java technology, and shows you what is special about object-oriented programming. In the second part called Java Language, everything revolves around the subtleties of the Java language and this is where the first small Java applications are created, aided by a fine blend of the knowledge part and practical exercises. Java Technology is both the name and the focus of the third part which also introduces you to the rules to observe when programming, what class libraries are and what advantages they have. In addition, you will learn how to test programs, what algorithms are, and how to program them. The fourth part, Java Projects, enables you to apply all the previous elements in an application with a graphical user interface. The project shows how to develop a larger application piece by piece with the Eclipse development environment. The Appendix concludes with a section on frequent errors that can occur when working with Eclipse, and a Glossary.

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.
