A Combat Guide against E-waste and Throwawayism This book is for anyone who enjoys tinkering with analog and digital hardware electronics. Regardless of the sophistication of your workspace, only basic tools are required to achieve truly satisfying results. It is intended as a reference guide among other hardware repair publications you may have in your library. However, the book goes a step further than most other repair guides in addressing issues in the modern era of discarded electronics called e-waste. E-waste should be put to good use. Producing anything new requires not just precious resources and labor, but also energy to make and deliver it to global retail shelves. Your talents and love of electronics can be put to good use by rescuing and resurrecting at least selected units from this endless stream of e-waste. Examples include either restoring through repair, or salvaging reusable electronic and mechanical components for your next project. Smart tips are provided throughout the book, and much information is tabulated for easy reference. The book expands age-old repair and hacking techniques applied for repair on the workbench into clever methods and applications to achieve effective results with discarded or “non-servicable” electronic consumer products. The final chapter provides real-life examples using all of the previously discussed content in a summarized form for each example repair type.

No-Code KI für Maker und Entwickler Dieses Buch nimmt Heraklits Leitsatz "Panta rhei – alles fließt" als Ausgangspunkt, um den Wandel und die Dynamik moderner Lebens- und Arbeitswelten zu beleuchten. Arbeitsabläufe – sogenannte Workflows – durchziehen sowohl das private als auch das geschäftliche Umfeld. Sie entstehen aus dem Zusammenspiel einzelner, oft banaler Handlungen, die in eine sinnvolle Reihenfolge gebracht werden. Diese Abläufe lassen sich manuell ausführen, doch durch Automatisierung und digitale Hilfsmittel werden sie deutlich effizienter und belastbarer. Ein besonderer Fokus liegt auf dem Einsatz Künstlicher Intelligenz (KI), die sich mit rasanter Geschwindigkeit in immer mehr Lebensbereiche integriert. Ob automatische Übersetzungen, persönliche Assistenzen oder intelligente Infrastrukturen – KI-Systeme wie ChatGPT oder DeepSeek bieten vielfältige Möglichkeiten zur Prozessvereinfachung. Im privaten Bereich sind smarte Häuser ein Beispiel, im geschäftlichen Umfeld sind es komplexe Reaktionsketten auf bestimmte Situationen, bei denen KI gezielt eingesetzt wird. Für die praktische Umsetzung solcher Prozesse bietet das Buch eine Einführung in das Low-Code-Tool n8n, das es ermöglicht, auch komplexe Workflows ohne klassische Programmierung zu gestalten. Mit über 500 fertigen Integrationen verbindet n8n verschiedenste Anwendungen miteinander und kann durch KI-Module ergänzt werden. Das Buch zeigt auf leicht verständliche Weise, wie sich solche Systeme sowohl im Alltag als auch in Unternehmen nutzen lassen – für mehr Effizienz, Struktur und technologische Souveränität. Alle Linux-Befehle und Dateieinträge zur Konfiguration von Anwendungen stehen für Sie als Download bereit. Downloads GitHub

De werking van veruit de meeste moderne elektronische apparaten is niet slechts op één enkel principe gebaseerd. Vaak staat een of andere computer (doorgaans een microcontroller) centraal. Uit deze fundamentele opzet – een computer die is ingebed in een bepaalde toepassingsschakeling – is de algemene benaming Embedded Systems voortgekomen. De meeste van deze systemen moeten vanuit het niets worden ontwikkeld, en daarbij komt het op elk detail aan. Vindingrijkheid en veelzijdigheid zijn dan een vereiste. De problemen die opgelost moeten worden, vormen niet zelden een ware uitdaging en betreffen niet alleen de analoge en digitale elektronica maar ook de systeemarchitectuur, programmering en programma-organisatie. De delen van deze reeks zijn geschreven voor iedereen – leerling, student of beginnend elektronicus – die zich terdege wil bekwamen in de professionele hardware- en systeemontwikkeling. En ze richten zich tot de allround-elektronicus die geen tijd heeft om specialist op een van de vele deelgebieden te worden maar die weet dat hij met standaard huis-, tuin- en keukenoplossingen niet ver komt. Ze bieden wat studenten en professionele elektronici nodig hebben: een opfrissing en verdieping van de basiskennis, een bron van inspiratie en een schat aan details en spitsvondigheden. Dit deel behandelt de passieve componenten: vaste weerstanden instelbare weerstanden NTC- en PTC-weerstanden spanningsafhankelijke weerstanden condensatoren spoelen transformatoren contactelementen
