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.

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.

Using the RFID Starter Kit An Arduino board has now become ‘the’ basic component in the maker community. No longer is an introduction to the world of microcontrollers the preserve of the expert. When it comes to expanding the capabilities of the basic Arduino board however, the developer is still largely on his own. If you really want to build some innovative projects it’s often necessary to get down to component level. This can present many beginners with major problems. That is exactly where this book begins. This book explains how a wide variety of practical projects can be built using items supplied in a single kit together with the Arduino board. This kit, called the 'RFID Starter Kit for Arduino' (SKU 17240) is not just limited to RFID applications but contains more than 30 components, devices and modules covering all areas of modern electronics. In addition to more simple components such as LEDs and resistors there are also complex and sophisticated modules that employ the latest technology such as: A humidity sensor A multicolor LED A large LED matrix with 64 points of light A 4-character 7-segment LED display An infra red remote-controller unit A complete LC-display module A servo A stepper motor and controller module A complete RFID reader module and security tag On top of that you will get to build precise digital thermometers, hygrometers, exposure meters and various alarm systems. There are also practical devices and applications such as a fully automatic rain sensor, a sound-controlled remote control system, a multifunctional weather station and so much more. All of the projects described can be built using the components supplied in the Elektor kit.

ÉLECTRICITÉ PHOTOVOLTAÏQUE = ÉLECTRICITÉ GRATUITE Nous sommes désormais plus qu'heureux de poursuivre nos recherches sur notre propre autonomie et de veiller à ce que notre production électrique photovoltaïque soit appropriée ! D'abord on en rêve, puis vient l'étape du calcul : comparer le coût du kilowattheure d'origine du nucléaire (environnement à partir de centimes d'euro) et le calcul du kilowattheure d'origine photovoltaïque (l'environnement de 22 centimes de l'euro*), et nous saurons où en sont nos motivations d'écocitoyens. Gérard Guihéneuf, l'auteur de ce nouveau livre, pense qu'il ne faut pas se contenter d'aligner chiffres et idées. La nouvelle approche du processus de création d'entreprise se base sur la compréhension et les dimensions des installations des bâtiments domestiques dans le domaine public en 2009 et sur l'actualité des techniques et pratiques de réponse aux questions qui se posent lors de l'électrification des le site isolé ! La conception de projets simples, comme un contexte domestique, et d'un commentaire électrique standard, comme un système d'énergie photovoltaïque, trois emplacements réguliers : un abri dans le jardin, un garage et un mobil-home. L'économie est spectaculaire lorsqu'il s'agit de composants électroniques et d'assemblages de certains constituants essentiels, car les régulateurs de charge, les onduleurs et les panneaux solaires ne suffisent pas à l'entretien autonome du site. Si vous souhaitez en savoir plus sur l'électrification professionnelle de votre chantier, vous pouvez en savoir plus sur les dimensions des éléments constitutifs sans sacrifier l'efficacité ! Vous pouvez également utiliser la copie du Gerber et du Sprint Layout pour les circuits imprimés de la livrée. *avec les batteries en cours de reconditionnement lors de la panne photovoltaïque en cours et dans les vingt-cinq

The State of Hollow State Audio in the Second Decade of the 21st Century Vacuum-tube (or valve, depending upon which side of the pond you live on) technology spawned the Age of Electronics early in the 20th Century. Until the advent of solid-state electronics near mid-century, hollow-state devices were the only choice. But following the invention of the transistor (after their process fell to reasonable levels), within a couple of decades, the death of vacuum tubes was widely heralded. Yet here we are some five decades later, and hollow-state equipment is enjoying something of a comeback, especially in the music and high-end audio industries. Many issues surround hollow-state audio: Does it produce—as some claim—better sound? If so, is there science to back up these claims? How do hollow-state circuits work? How do you design hollow-state audio circuits? If hollow-state equipment fails, how do you go about troubleshooting and repairing it? Can we recreate some of the classic hollow-state audio devices for modern listening rooms and recording studios? How can we intelligently modify hollow-state amplifiers to our taste? These and other topics are covered in The State of Hollow State Audio.
