Elektor Digital FreeCAD für Elektroniker (PDF)
Praktische Einführung in 3D-Modellierung vom Gehäuse bis zu Frontplatten Ein historisches Bauteil einbetten, eine professionell anmutende Heimstätte für eine Leiterplatte schaffen oder ein komplexes Gerät mit Chassis konstruieren – diese und viele andere Herausforderungen werden mit FreeCAD zu einem anregenden Vergnügen. Hat man die grundlegenden Prozesse erst einmal verinnerlicht, sind der Fantasie praktisch keine Grenzen mehr gesetzt. Der Einstieg in ein neues Programm ist immer schwierig – besonders wenn es sich um ein so vielfältiges Werkzeug wie FreeCAD handelt. Überschaubare, aber zugleich gut verwendbare Einzelteile liefern in diesem Buch den Anfangspunkt. Das Zusammensetzen dieser Komponenten führt später zu Baugruppen. In der Vielfalt der Möglichkeiten von FreeCAD wird ein gangbarer Weg gezeigt. Das beschriebene Vorgehen ist exemplarisch – die Beispiele lassen sich daher leicht auf eigene Aufgaben anwenden. Die Geräte wurden vom Autor angefertigt und mit Fotos illustriert. Eine 3D-Konstruktion erfordert etwas Aufwand, der sich aber lohnt: Neben einer beeindruckenden Darstellung von Projekten wird zugleich die Möglichkeit geliefert, z. B. Blechteile zur Fertigung abzuwickeln und für die Werkstatt aussagekräftige Zeichnungen zu exportieren. Schon bald werden Sie auf FreeCAD nicht mehr verzichten wollen!

Elektor Digital LabVIEW 2 (PDF)
Das Programmpaket Laboratory Virtual Instrument Engineering Workbench (oder kurz LabVIEW) ist ein international anerkannter Standard zur Entwicklung und Gestaltung von Messgeräten und Prozesssteueroberflächen. Seine Universalität konfrontiert den LabVIEW-Einsteiger allerdings mit einer unübersichtlichen Vielfalt von Funktionen, die er ohne fundierte Anleitung kaum überblicken kann. Hier setzt diese neue mehrteilige Lehrbuchreihe an: Von Grund auf werden in einfach nachvollziehbaren Schritten der Aufbau, die Struktur und die Verwendung von LabVIEW erklärt, in praktischen Beispielen dargestellt und mit Übungen vertieft. Die notwendigen Vorkenntnisse sind äußerst gering, die erreichbaren Ergebnisse dagegen äußerst sehenswert. Der erste Band erläutert die Grunddatentypen und die zugehörigen numerischen Grundfunktionen ebenso ausführlich wie die elementaren Programmstrukturen. Im folgenden Band liegt der Schwerpunkt bei der Kopplung beliebiger Mikrocontrollersysteme über die serielle (USB-)Schnittstelle an den PC und an LabVIEW. Im dritten Band stehen Entwurf und Betrieb kompletter MSR-Systeme mit Hard- und Softwarekomponenten der wichtigsten Messtechnikhersteller im Vordergrund, einschließlich Fernsteuerung, -überwachung und -diagnose über das Internet oder WLAN-Systeme. Diese Lehrbuchreihe richtet sich an Schüler/Auszubildende technischer Bildungseinrichtungen, an Studenten von Fachhochschulen/Universitäten und an den engagierten Praktiker in der Industrie oder im privaten Bereich.

Elektor Digital Programming Voice-controlled IoT Applications with Alexa and Raspberry Pi (E-book)
Learn programming for Alexa devices, extend it to smart home devices and control the Raspberry Pi The book is split into two parts: the first part covers creating Alexa skills and the second part, designing Internet of Things and Smart Home devices using a Raspberry Pi. The first chapters describe the process of Alexa communication, opening an Amazon account and creating a skill for free. The operation of an Alexa skill and terminology such as utterances, intents, slots, and conversations are explained. Debugging your code, saving user data between sessions, S3 data storage and Dynamo DB database are discussed. In-skill purchasing, enabling users to buy items for your skill as well as certification and publication is outlined. Creating skills using AWS Lambda and ASK CLI is covered, along with the Visual Studio code editor and local debugging. Also covered is the process of designing skills for visual displays and interactive touch designs using Alexa Presentation Language. The second half of the book starts by creating a Raspberry Pi IoT 'thing' to control a robot from your Alexa device. This covers security issues and methods of sending and receiving MQTT messages between an Alexa device and the Raspberry Pi. Creating a smart home device is described including forming a security profile, linking with Amazon, and writing a Lambda function that gets triggered by an Alexa skill. Device discovery and on/off control is demonstrated. Next, readers discover how to control a smart home Raspberry Pi display from an Alexa skill using Simple Queue Service (SQS) messaging to switch the display on and off or change the color. A node-RED design is discussed from the basic user interface right up to configuring MQTT nodes. MQTT messages sent from a user are displayed on a Raspberry Pi. A chapter discusses sending a proactive notification such as a weather alert from a Raspberry Pi to an Alexa device. The book concludes by explaining how to create Raspberry Pi as a stand-alone Alexa device.

Elektor Digital Technical Modeling with OpenSCAD (E-book)
Create Models for 3D Printing, CNC Milling, Process Communication and Documentation Engineers dread designing 3D models using traditional modeling software. OpenSCAD takes a refreshing and completely different approach. Create your models by arranging geometric solids in a JavaScript-like language, and use them with your 3D printer, CNC mill, or process communication. OpenSCAD differs from other design systems in that it uses programmatical modeling. Your model is made up of primitives that are invoked using a C-, Java- or Python-like language. This approach to model design is close to the “mechanical work” done in the real world and appeals to engineers and others who are not a member of the traditional creative class. OpenSCAD also provides a wide variety of comfort functions that break the 1:1 relationship between code and geometry. This book demonstrates the various features of the programming language using practical examples such as a replacement knob for a LeCroy oscilloscope, a wardrobe hanger, a container for soap dispensers, and various other real-life examples. Written by an engineer with over 15 years of experience, this book is intended for Linux and Windows users alike. If you have programming experience in any language, this book will have you producing practical three-dimensional objects in short order!
