In 35 Projects with the Raspberry Pi and Arduino The Internet of Things (IoT) is a trend with a strong technological impulse. At home, we want to do everything on our tablets, from browsing Facebook to watching TV, from operating lights to keeping an eye on the temperature. In 35 fun projects, this book will show you how to build your own Internet of Things system. We'll cover the hardware (primarily the Raspberry Pi and Arduino) and the software that makes control via Internet possible. We employ Wi-Fi and radio links so no requirement any longer to install cabling crisscross through your home. Assuming the projects in the book are finished, you have a complete Internet of Things system that allows you to control and view of everything in your home. For example, if there's something in the mail box or the car is securely in the garage. Also, you can switch on the lights and the alarm from your couch. The crisp explanations allow the projects to be customized with ease, for example, to turn on your coffee machine or TV remotely. The index gives easy access to creative projects that can serve as an example, enabling you to do all the connecting to the IoT independently. All project software can be downloaded free of charge from the Elektor website. In this unique book, Raspberry Pi, Arduino and HTML webpages with stylesheets and JavaScript come together in clearly-described, easy-to-build projects. This special book is an essential part of your collection!

Komponenten werden von Jahr zu Jahr immer kleiner und feinere Abstände sind gefragt. Gleichzeitig kann es jedoch sein, dass Ihre Leiterplatten größer geworden sind oder die Anzahl der miteinander verbundenen Leiterplatten oder die Anzahl der benötigten berührungslosen PCBite-Sonden zur Prüfung Ihres Designs zugenommen haben, was zu Platzmangel auf unseren kleineren Basisplatten führen kann. Funktionen Mit einer Größe von 297 x 420 mm (DIN A3) bietet die extragroße Basisplatte Platz für die meisten Leiterplatten und viele berührungslose PCBite-Sonden für Messungen, bei denen mehr Kanäle benötigt werden als verfügbar sind. Wenn Sie also mehr Platz, zusätzlichen Schutz oder einfach nur Ordnung auf Ihrer Arbeitsfläche wünschen, ist dieses Zubehör perfekt geeignet. Entwickelt für den Einsatz mit Sensepeeks magnetischer PCBite-Produktlinie, einschließlich Leiterplattenhaltern, berührungslosen Sonden und Vergrößerungsglas. Im Lieferumfang enthalten 1x XL-Basisplatte (DIN A3) mit vormontierter Isolierabdeckung

Dieses durchsichtige Acrylgehäuse ist das offizielle Gehäuse für das HackRF One/Pro Board. Es kann das schwarze Standard-Kunststoffgehäuse des HackRF One/Pro ersetzen. Montageanleitung Verwenden Sie einen Gitarrenpick oder einen Spudger, um die HackRF One/Pro Platine aus dem schwarzen Kunststoffgehäuse zu ziehen. Setzen Sie eine lange Schraube in jede Ecke der unteren Acrylplatte ein. Sichern Sie jede lange Schraube mit einem kurzen (5 mm) Abstandshalter auf der gegenüberliegenden Seite der Platte. Legen Sie die HackRF One/Pro Platine (mit der Oberseite nach oben) auf die untere Platte und führen Sie die Enden der langen Schrauben durch die Befestigungslöcher in den Ecken der Leiterplatte. Sichern Sie die Platine mit einem langen (6 mm) Abstandshalter in jeder Ecke. Legen Sie die obere Acrylplatte auf die Leiterplatte und richten Sie die Ausschnitte mit den Erweiterungsleisten der Leiterplatte aus. Sichern Sie jede Ecke mit einer kurzen Schraube. Wichtig: Bei jedem Schritt nur handfest (nicht zu fest) anziehen.

Die PCBite Lupe (Premium-Verarbeitungsqualität aus CNC-gefrästem Aluminium) vergrößert Ihr Produkt und macht es einfacher, während des Lötens, der Fehlersuche und der Messungen zu sehen. Besonders nützlich bei der Platzierung von PCBite Freihand-Tastköpfen auf Fine Pitch SMD-Komponenten während der Messungen. Kantenlose Linse mit 3-facher Vergrößerung für bessere Sicht auf die Arbeitsfläche und AR-Beschichtung (Antireflexionsbeschichtung) zur Verringerung von Reflexionen durch nahe Lichtquellen. Optimiertes Design, Vergrößerung und Brennpunkt für die Verwendung zusammen mit den PCBite Leiterplattenhaltern und Grundplatten, die in allen PCBite Kits enthalten sind. Kann auch in der Hand gehalten werden, aber nicht eigenständig ohne eine Metalloberfläche als Basis. An der Unterseite des Lupenfußes befindet sich ein starker Magnet, der in seiner Stärke perfekt ausbalanciert ist. Eine reibungsarme Bodenkappe schützt den Magneten und die Grundplatte, so dass die Lupe leicht gleiten kann, wenn sie neu positioniert oder von der Grundplatte entfernt wird. Die reibungsbasierte Einstellung der Linsenneigung und -drehung macht lästige und komplizierte Stellschrauben überflüssig.

This book is intended for electronics enthusiasts and professionals alike, who want a much deeper understanding of the incredible technology conquests over the pre-digital decades that created video. It details evolution of analogue video electronics and technology from the first electro-mechanical television, through advancements in Cathode Ray Tubes, transistor circuits and signal processing, up to the latest analogue, colour-rich TV, entertainment devices and calibration equipment. Key technological advances that enabled monochrome video and, eventually, colour are explained. The importance, compromises and techniques of maintaining crucial backward legacy compatibilities are described. The generation, signal processing and playback of analogue video signals in numerous capture, display, recording and playback devices together with operating principles and practices are examined. Technical and, often, political merits and deficiencies of key national and international video standards are highlighted. Several formats are shown to win and ultimately to co-exist. This book begins at fairly basic levels; concepts are introduced with human physiological perceptions of light and colour explained. This leads to the subject matter of luminance and chrominance; their equations and the circuits to process. There is full, detailed analysis of waveform shapes and timings inside video equipment and relevant popular connections e.g. S-video. Several analogue video projects which you can build yourself are also included in this book; with schematics, circuit board layouts and calibration steps to help you obtain the best results. The book makes use of many colour pages where the subject matter demands it (e.g. test cards). If you really want a deeper understanding of analogue video then this book is for you!
