Electronic devices increasingly come with glued displays and batteries. And while the adhesive seal serves as a protection against dirt and water, it complicates the opening procedure of the device and hence its repair. The iOpener: Warm it through, unstick the glue! With the help of our iOpener, you can easily and quickly loosen adhesive without risking damage to your device due to overheating with a heat gun. Originally designed for opening Apple iPads, the iOpener is just as suitable for Samsung tablets, Sony smartphones, and devices from any other manufacturer who prefers adhesive over screws. How it works Heat the iOpener and place it on your device: Simply heat up the iOpener in the microwave or a pot of boiling water and position it on the edge of your device. The heat will soften the adhesive without damaging your gadget so you can insert an opening pick between the display and the case. Repeat this procedure for all glued areas, the iOpener is reusable any number of times. Use opening tools to remove adhesive residue: With the right tools, you’re now ready to open your device without hassle. The opening picks are sharp-edged enough to cut through the adhesive strips. Complete the opening procedure by prying up the case with an opening tool or lift your display with a suction cup or an iSclack. A must-have for electronic repairs The most annoying part of your repair is done, the rest will be almost a cinch. Whether you are a beginner or a professional, the iOpener should be part and parcel of every toolbox worthy of its name. Your advantages Loosen adhesive fastenings Uncomplicated to heat up in the microwave or boiling water Reusable Optionally available with opening tools Contains food grade glycerine Saves money and the planet Included iOpener Spudger iFixit Opening Tool 6x iFixit Opening Picks iFixit Battery Isolation Pick Plastic Cards Suction Cup Angled Tweezers Plastic bit driver with magnetic bit socket (4 mm), rubberized handle and swivel cap Precision bits (4 mm) Phillips #00 Flathead 2.5 mm

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)

Drahtlose Kommunikation – sei es zur Ton-, Daten- oder Bildübertragung – prägt unser heutiges Leben. Während noch Mitte des letzten Jahrhunderts der Rundfunk (und etwas später das Fernsehen) die dominierenden Anwendungen der drahtlosen Kommunikation waren, gibt es heute kaum mehr ein technisches Gerät, das nicht das Mittel der drahtlosen Kommunikation nutzt. Allen voran das beliebte Smartphone. Daneben gibt es sehr viele Anwendungen, die wir nicht sofort und automatisch mit den Begriffen Radio oder Funk verbinden, die aber auf der Nutzung elektromagnetischer Strahlung basieren. So zum Beispiel der Wagenschlüssel, die über Bluetooth verbundenen Kopfhörer, der automatische Rasenmäher, die gehassten Radargeschwindigkeitsmesser, der Laptop, der über Wi-Fi mit dem Internet verbunden ist, die kleinen Navigationsempfänger, usw. Diesen Anwendungen gemeinsam ist die Nutzung physikalischer Gegebenheiten durch die Technik. Ob Radar, Satellitenfernsehen, oder einfach nur das alte Mittelwellenradio, alle bauen auf denselben Grundlagen auf. Das Ziel dieses Buch ist es, diese Grundlagen zu erläutern und damit das Verständnis für die darauf aufbauenden Anwendungen zu fördern. Es soll Studenten den Einstieg ins Fachgebiet erleichtern und Voraussetzungen für den Zugang zu den Standardwerken der Fachliteratur schaffen. Es richtet sich aber auch an Personen, die an der Physik und der Technik interessiert sind und einen tieferen Einblick in die Grundlagen der drahtlosen Kommunikation und deren Anwendung erhalten wollen.

Beginselen van het programmeren Eenvoudige projecten voor beginners Interface- en hardware-uitbreidingen Complexe projecten voor gevorderden Twee zaken hebben in belangrijke mate bijgedragen aan het grote succes van het Arduinoplatform. De eerste is de complete, gebruiksklare processorprint die de kennismaking met dehardware aanzienlijk vergemakkelijkt. En de tweede is de gratis verkrijgbare programmeerinterface, die zonder ingewikkelde installatieprocedures meteen gebruikt kan worden. Eenvoudige projecten voor beginners garanderen snelle resultaten. Het is niet nodig eerst ingewikkelde parameters (processortype of interface-instellingen) te selecteren -- de eerste voorbeeldprogramma's kunnen al na enkele minuten in de Arduino worden geladen en uitgeprobeerd. De Arduino-gebruiker wordt geholpen door een groot aantal software-bibliotheken -- maar deze nog dagelijks groeiende schat aan libraries vormt juist voor de beginner een luxe-probleem: na de eerste eenvoudige voorbeelden is het niet altijd even duidelijk hoe het nu verder moet. Bij de in het internet circulerende projecten ontbreekt het in veel gevallen aan gedetailleerd commentaar en uitleg. Er is geen duidelijk herkenbare leidraad, en eigenlijk is dat ook niet zo vreemd omdat de toepassingen door verschillende mensen voor verschillende doeleinden zijn ontwikkeld. Dat is waar dit boek te hulp komt. Projecten worden op een systematische manier gepresenteerd, waarbij elk project een ander onderwerp belicht. De aanpak is praktijkgericht, maar de noodzakelijke theoretische achtergrond wordt daarbij niet uit het oog verloren. Belangrijke onderwerpen zoals A/D-omzetting, timers en interrupts worden steeds in praktische projecten 'ingebed'. In het boek komen zaken als looplicht-effecten, praktisch bruikbare voltmeters, nauwkeurige digitale thermometers, allerlei soorten klokken, reactietesters en zelfs een muisgestuurde robotkraan aan de orde. En al lezende en doende krijgt de lezer een gedegen inzicht in de achterliggende controllertechnieken.
