Developing CoAP applications for Thread networks with Zephyr This book will guide you through the operation of Thread, the setup of a Thread network, and the creation of your own Zephyr-based OpenThread applications to use it. You’ll acquire knowledge on: The capture of network packets on Thread networks using Wireshark and the nRF Sniffer for 802.15.4. Network simulation with the OpenThread Network Simulator. Connecting a Thread network to a non-Thread network using a Thread Border Router. The basics of Thread networking, including device roles and types, as well as the diverse types of unicast and multicast IPv6 addresses used in a Thread network. The mechanisms behind network discovery, DNS queries, NAT64, and multicast addresses. The process of joining a Thread network using network commissioning. CoAP servers and clients and their OpenThread API. Service registration and discovery. Securing CoAP messages with DTLS, using a pre-shared key or X.509 certificates. Investigating and optimizing a Thread device’s power consumption. Once you‘ve set up a Thread network with some devices and tried connecting and disconnecting them, you’ll have gained a good insight into the functionality of a Thread network, including its self-healing capabilities. After you’ve experimented with all code examples in this book, you’ll also have gained useful programming experience using the OpenThread API and CoAP.

Elektronica moeilijk? De titel van dit boek geeft het antwoord! In deze 3-in-1-band wordt de elektronica vanuit de praktijk benaderd. Dat wil zeggen veel praktijk in de vorm van experimenten en een minimum aan theorie. Zo raakt u stap voor stap vertrouwd met de behandelde onderwerpen. Daarbij ontstaan gaandeweg ook een flink aantal praktisch bruikbare schakelingen. Het gaat bij de elektronicahobby tenslotte om het bouwen of uitdenken van allerlei praktische of leuke schakelingen. Aan het eind van elk deel is een aanhangsel opgenomen met aanvullende informatie en de gegevens van een groot aantal elektronische componenten, zodat na dit boek ook eigen ideeën en experimenten kunnen worden aangepakt. In deze 3-in-1-band zijn de eerste drie delen uit de serie “Elektronica echt niet moeilijk” samengevoegd: Deel 1: experimenten met gelijkstroom Deel 2: experimenten met wisselstroom Deel 3: experimenten met digitale techniek

Practical Low-Cost Methods for Reliable PCB Production This book explains how to carry out reliable SMD assembly using affordable tools and small-scale equipment. It follows the complete workflow step by step, including tool selection, solder paste handling, stencil use, component placement, reflow methods, inspection, and rework. The focus is on bench-level and small-lab production rather than industrial assembly lines. It shows practical methods for building single and double-sided SMD boards with repeatable results. Topics include solder paste and flux, temperature profiles, hot air and hotplate techniques, small reflow ovens, inspection methods, and defect correction. Checklists and example workflows are included to help reduce errors and improve consistency. Key features: Tools and supplies for SMD assembly and rework Solder paste types, storage, and handling Stencils and paste application methods Pick and place workflow and component orientation Temperature profiles and reflow methods Hot air, hotplate, and reflow oven processes Inspection and quality control Common defects such as tombstoning and solder bridges Practical rework and component replacement Bench-level professional workflows and checklists This book is designed as a practical bench reference for anyone who wants to assemble and troubleshoot their own SMD boards with reliable results.

Grundlagen und Simulation mit Multisim Analoge Filterschaltungen bilden die schaltungstechnischen Grundlagen in der Elektronik, Messtechnik, Nachrichtentechnik, Computertechnik usw. Die Bauelemente Widerstand, Kondensator und Spule sind die Grundlagen der passiven Filtertechnik. Filter haben Einfluss auf die Signalamplitude, die Signalform (zeitlicher Verlauf) und Signallaufzeit (Signalverlauf). Mit diesen Voraussetzungen werden Zweipole, Vierpole, Hoch- und Tiefpässe behandelt. Daraus resultieren Frequenz- und Phasengang, Dämpfung, Bandpass, Bandsperre und Doppel-T-Filter. Der Operationsverstärker arbeitet als Verstärker in der aktiven Filtertechnik. Erklärt werden in diesem Buch auch aktive Hoch- und Tiefpassfilter der 1., 2., 3. und höherer Ordnung, Unterschiede zwischen Gauß-, Bessel-, Butterworth- und Tschebyscheff-Funktionen, aktive Bandpass- und Bandsperrfilter, Allpassfilter und Universalfilter. Dieses Buch basiert auf dem bekannten Programm Multisim und Spice. Damit lassen sich alle Versuche simulieren.
