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.

A Guide to Powerful Programming for Embedded Systems You must be a well-rounded professional to excel in the ever-evolving, rapidly developing embedded design and programming industry. Simply put, when it comes to electronics design and programming, the more topics you can master, the more you’ll flourish at your workplace and at your personal workbench. This shouldn’t be a surprise, as the line between the skills of a hardware engineer and software engineer is blurring. The former should have a good grasp of programming in order to build efficient systems. The latter should understand the details of the design (whether it’s a physical or virtual application) for which he or she is writing code. Thus, to be successful, a modern professional electronics engineer must have a solid grasp of both hardware design and programming. Assembly Language Essentials is a matter-of-fact guide to Assembly that will introduce you to the most fundamental programming language of a processor. Unlike other resources about Assembly that focus exclusively on specific processors and platforms, this book uses the architecture of a fictional processor with its own hardware and instruction set. This enables you to consider the importance of Assembly language without having to deal with predetermined hardware or architectural restrictions. You’ll immediately find this thorough introduction to Assembly to be a valuable resource, whether you know nothing about the language or you have used it before. The only prerequisite is that you have a working knowledge of at least one higher-level programming language, such as C or Java. Assembly Language Essentials is an indispensible resource for electronics engineering professionals, academics, and advanced students looking to enhance their programming skills. The book provides the following, and more: An introduction to Assembly language and its functionality Significant definitions associated with Assembly language, as well as essential terminology pertaining to higher-level programming languages and computer architecture Important algorithms that may be built into high-level languages, but must be done the “hard way” in Assembly language — multiplication, division, and polynomial evaluation A presentation of Interrupt Service Routines with examples A free, downloadable Assembler program for experimenting with Assembly

Architecture, Programming and Applications The MSP430 is a popular family of microcontrollers from Texas Instruments. In this book we will work with the smallest type, which is the powerful MSP430G2553. We will look at the capabilities of this microcontroller in detail, as it is well-suited for self-made projects because it is available in a P-DIP20 package. We will take a closer look at the microcontroller and then build, step by step, some interesting applications, including a 'Hello World' blinking LED and a nice clock application, which can calculate the day of the week based on the date. You also will learn how to create code for the MSP microcontroller in assembler. In addition to that, we will work with the MSP-Arduino IDE, which makes it quite easy to create fast applications without special in-depth knowledge of the microcontrollers. All the code used in the book is available for download from the Elektor website.

The Raspberry Pi Global Shutter Camera is a specialised 1.6 MP camera from Raspberry Pi that is able to capture rapid motion without introducing artefacts typical of rolling shutter cameras. It is ideally suited to fast motion photography and to machine vision applications, where even small amounts of distortion can seriously degrade inference performance. With a large pixel size of 3.45 x 3.45 ?m providing high light sensitivity, the Global Shutter Camera can operate with short exposure times (as low as 30 ?s with adequate lighting), an advantage for high-speed photography. It features a 1.6 MP Sony IMX296 sensor, and it has the same C/CS-mount lens assembly as the Raspberry Pi High Quality Camera, for compatibility with the same broad variety of lenses. In common with other global shutter sensors, the IMX296 has a lower resolution than similarly sized rolling shutter sensors; a low pixel count is appropriate for machine vision applications, where high-resolution images are challenging to process in real time. The Global Shutter Camera's lower resolution means that with appropriate lens magnification, an image suitable for processing by a machine vision model can be captured natively. The Raspberry Pi Global Shutter Camera is compatible with any Raspberry Pi computer that has a CSI connector. Specifications Form factor 38 x 38 x 19.8 mm (29.5 mm adapter and dust cap) Weight 34 g (41 g with adapter and dust cap) Sensor Sony IMX296LQR-C Resolution 1.58 MP (color) Sensor size 6.3 mm (sensor diagonal) Pixel size 3.45 x 3.45 ?m Output RAW10 Back focus length of lens Adjustable (12.5-22.4 mm) Lens standards CS-MountC-Mount (C-CS adapter included) IR cut filter Integrated Ribbon cable length 150 mm Included accessories C-CS mount adapterScrewdriver Tripod mount 1/4”-20 Included Raspberry Pi Global Shutter Camera C-CS mount adapter Screwdriver Ribbon cable (150 mm) Downloads Datasheet

Contents Basic principles A connector is an electromechanical system that provides a separable connection between two subsystems of an electronic device without an unacceptable effect on the performance of the device. It will be shown that there are a lot of complex parameters to handle properly to make this statement true. Design / Selection / Assembly This chapter provides an overview of design and material requirements for contact finishes, contact springs and connector housings as well as the major degradation mechanisms for these connector components. To complete this chapter, material selection criteria for each will also be reviewed. Additionally the Level of Interconnection (LOI) was integrated into this chapter as it addresses, where the connector is used within an electronic system and therefore influences the requirements and durability of the connector depending on its use. Applications This chapter is heading to the practical work and shows how customers use connectors in their applications to offer some possibilities and to ease your daily work. Additionally it contains some special topics like tin-whisker or impedance of ZIF cable to offer you extended background knowledge.
