Construisez votre station météo idéale ou explorez les données environnementales avec le monde entier. Avec de nombreux projets pratiques pour Arduino, Raspberry Pi, NodeMCU, ESP32 et autres cartes de développement. Les stations météo jouissent d’une grande popularité depuis des décennies. Tous les magazines d’électronique, qu’ils soient récents ou non, ont publié et publient régulièrement des articles sur la construction d’une station météo. Au fil des années, elles sont devenues de plus en plus sophistiquées et peuvent aujourd’hui être entièrement intégrées dans la maison intelligente. Ceci implique toutefois souvent une fidélité à un fabricant de produits de marque (coûteux) pour tous les composants. Cependant, avec votre propre station météo, vous pouvez facilement suivre le rythme et même capturer des relevés que les appareils commerciaux ne peuvent pas réaliser. Le plaisir ne manque pas : vous développerez de manière ludique vos connaissances en électronique, en cartes de développement de microcontrôleurs modernes et en langages de programmation. Pour moins de dix euros, vous pouvez collecter des données environnementales initiales et étendre votre système au fur et à mesure que votre intérêt grandit.

Analogue Electronics and Microcontrollers Projects Hobbyist electronics can be a fun way to learn new skills that can be helpful to your career. Those who understand the basics of electronics can design their own circuits and projects. However, before you run, you need to learn to walk. It all starts with analogue electronics. You should be familiar with the simple components and circuits and understand their basic behaviors and the issues you may encounter. The best way to do this is through real experiments. Theory alone is not enough. This book offers a large number of practical entry-level circuits, with which everyone can gain the basic experience. Through the widespread introduction of microcontrollers, a new chapter in electronics has begun. Microcontrollers are now performing more and more tasks that were originally solved using discrete components and conventional ICs. Starting out has become easier and easier thanks to platforms including Bascom, Arduino, micro:bit. The book introduces numerous manageable microcontroller applications. It’s now a case of less soldering and more programming.

The Elektor Laser Head transforms the Elektor Sand Clock into a clock that writes the time on glow-in-the-dark film instead of sand. In addition to displaying the time, it can also be used to create ephemeral drawings. The 5 mW laser pointer, with a wavelength of 405 nm, produces bright green drawings on the glow-in-the-dark film. For best results, use the kit in a dimly lit room. Warning: Never look directly into the laser beam! The kit includes all the necessary components, but soldering three wires is required. Note: This kit is also compatible with the original Arduino-based Sand Clock from 2017. For more details, see Elektor Magazine 1-2/2017 and Elektor Magazine 1-2/2018.

As demand for solar panel installation has risen sharply, especially for installations larger than balcony power plants, the order books of solar companies are full. If you ask for a quote today, you may have to wait a while, if your request isn't simply postponed indefinitely. Another consequence of the solar boom is that some companies are charging very high prices for installations. Yet there is an obvious and radical solution to the problem of excessive prices: Do it yourself, as the English say. The price of materials is currently affordable, and it's the ideal time for those who do the work themselves. They couldn't save more. Add to this the satisfaction of doing something useful, both economically and ecologically, and the pleasure of building yourself. In this special issue, you'll find a wide selection of Elektor assemblies, from solar panel controllers to solar water heaters and solar panel orientation systems. The issue also contains practical information on solar panel installation and the technology behind them. Finally, there are a number of articles on the subject of balcony power plants, from how to install them to how to connect them to the Internet... Contents BASICS Dimensioning Photovoltaic Panel ArraysAn introduction to photovoltaic energy and the commonest techniques,followed by simplified calculation models and setup guidelines. Light Sensor TechnologyMeasuring daylight using LEDs. Solar Power Made SimpleSolar charging with and without a controller.
