En moins de 100 lignes de code par projet avec les cartes Feather Sense et Clue Express d'Adafruit Le langage de programmation Python est apprécié par les pédagogues parce que sa syntaxe le rend facile à comprendre. Il s'est également imposé chez les informaticiens expérimentés. La société Adafruit a développé une version spéciale de Python pour l'embarquer sur les microcontrôleurs à 32 bits : CircuitPython. Ce livre permettra au lecteur de s'initier à la programmation en CircuitPython sur deux cartes : Feather BlueFruit Sense (également appelée Feather nRF52840 Sense) et CLUE nRF52840 Express. Chacune est animée par le SoC nRF52840 de NORDIC avec une architecture à 32 bits. Pour ce voyage dans le monde de la programmation embarquée, l'auteur sort du chemin classique, à savoir un cours complet sur la programmation orientée objet appliquée à ce langage. Il préfère emmener le lecteur directement sur le terrain avec des projets qui mettent en oeuvre les cartes et différents périphériques. Plus d'une quarantaine d'exemples et de montages permettent de découvrir la richesse de CircuitPython. Toutefois l'auteur s'est imposé une limite pour ne pas décourager les novices : le code de chaque projet ne dépasse jamais la centaine de lignes. Pour ce qui est du matériel, là aussi la simplicité domine : aucun programmateur, un simple PC suffit ; aucun soudage grâce au câblage sur platine d'essai. Les cartes d'extension FeatherWing à enficher sur la Feather nRF52840 Sense permettent de démultiplier ses fonctions : matrice de LED, enregistreur de données, écran à encre électronique, écran OLED, écran TFT, commande de moteurs, audio, relais… Toutes les étapes (assemblage des différents composants, installation des bibliothèques requises, programmation, tests…) sont expliquées en détail. Le code des différents exemples et projets est disponible sur Github. Le résultat de chaque projet est même présenté sur de courtes vidéos disponibles sur YouTube. À la fin de sa lecture, le nouveau Pythonien pourra facilement approfondir les notions abordées et donner vie à ses propres projets grâce aux outils qu'il aura essayés. Ce livre s'adresse aux lycéens et étudiants ainsi qu'à toute la communauté des makers. Chaîne YouTube de l'auteur : YouTube (Michaël Bottin)

The Siglent SDS1104X-E employs a new generation of SPO (Super Phosphor Oscilloscope) technology that provides excellent signal fidelity and performance. The system noise is also lower than similar products in the industry. It comes with a minimum vertical input range of 500 uV/div, an innovative digital trigger system with high sensitivity and low jitter, and a waveform capture rate of 400,000 frames/ sec (sequence mode). The SDS1104X-E also employs a 256-level intensity grading display function and a color temperature display mode not found in other models in this class. SIGLENT’s latest oscilloscopes offering supports multiple powerful triggering modes including serial bus triggering. Serial decoding is free and includes IIC, SPI, UART, CAN, and LIN. History waveform recording and sequential triggering enable extended waveform recording and analysis. Another powerful addition is the new 1 Mpt FFT math function that gives the SDS1104X-E very high frequency resolution when observing signal spectra.

20+ Macintosh Models, from 1984 to Today (History, Engineering, and Restoration) Apple is not like any other company. More than anyone else, it transformed technology into something people could desire, love, and even identify with—much like a luxury brand. Users were not only buying a tool; they were buying a vision, a way of life. At the center of this transformation stands the Macintosh. First introduced in 1984, it was radically different from everything before. With its graphical interface and mouse, it made computing approachable, even friendly. What now feels obvious—clicking on icons, dragging files, pointing instead of typing commands—was revolutionary at the time. The Macintosh not only changed the way people related to technology. The Macintosh forced the entire industry to rethink the way we use computers. This book tells that story through some of the most significant Macintosh models. Each one is presented not only in words but also in images, because these computers are more than technology—they are design icons, symbols of a unique vision. History, technical detail, and photography come together here, aiming to show each Macintosh as it truly deserves to be seen.

If you enjoy DIY electronics, projects, software and robots, you’ll find this book intellectually stimulating and immediately useful. With the right parts and a little guidance, you can build robot systems that suit your needs more than overpriced commercial systems can. 20 years ago, robots based on simple 8-bit processors and touch sensors were the norm. Now, it’s possible to build multi-core robots that can react to their surroundings with intelligence. Today’s robots combine sensor readings from accelerometers, gyroscopes and computer vision sensors to learn about their environments. They can respond using sophisticated control algorithms and they can process data both locally and in the cloud. This book, which covers the theory and best practices associated with advanced robot technologies, was written to help roboticists, whether amateur hobbyist or professional, take their designs to the next level. As will be seen, building advanced applications does not require extremely costly robot technology. All that is needed is simply the knowledge of which technologies are out there and how best to use each of them. Each chapter in this book will introduce one of these different technologies and discuss how best to use it in a robotics application. On the hardware side, we’ll cover microcontrollers, servos, and sensors, hopefully inspiring you to design your own awe-inspiring, next-generation systems. On the software side, we’ll cover programming languages, debugging, algorithms, and state machines. We’ll focus on the Arduino, the Parallax Propeller, Revolution Education PICAXE and projects I’ve with which I’ve been involved, including the TBot educational robot, the PropScope oscilloscope, the 12Blocks visual programming language, and the ViewPort development environment. In addition, we’ll serve up a comprehensive introduction to a variety of essential topics, including output (e.g. LEDs, servo motors), and communication technologies (e.g. infrared, audio), that you can use to develop systems that interact to stimuli and communicate with humans and other robots. To make these topics as accessible as possible, handy schematics, sample code and practical tips regarding building and debugging have been included. Hanno Sander Christchurch, New Zealand

Deze doorzichtige acryl behuizing is de officiële behuizing voor het HackRF One/Pro board. Hij kan de standaard zwarte plastic behuizing van de HackRF One/Pro vervangen. Montage-instructies Gebruik een plectrum of spudger om de HackRF One/Pro printplaat uit de zwarte plastic behuizing te halen. Steek een lange schroef in elke hoek van het onderste acrylpaneel. Zet elke lange schroef vast met een kort afstandsstuk (5 mm) aan de tegenoverliggende kant van het paneel. Plaats de HackRF One/Pro printplaat (naar boven gericht) bovenop het onderpaneel en steek de uiteinden van de lange schroeven door de bevestigingsgaten in de hoeken van de print. Zet de printplaat vast met een lang afstandsstuk (6 mm) in elke hoek. Plaats het bovenste acrylpaneel op de printplaat en lijn de uitsparingen uit met de extension headers op de print. Zet elke hoek vast met een korte schroef. Opmerking: Niet te strak aandraaien! Na elke stap alleen met de hand aandraaien.
