Whatever the methods or even then financial means you have to make your circuits work, the power supply should rank high if not Number One in your considerations. The design block simply called “power supply” is hugely underrated both in electronics creation and repair. Yet, the “PSU” has enormous diversity and comes in wildly differing guises like AC/DC, generator, battery (rechargeable or not), PV panel, benchtop, linear or switch-mode, to mention but a few. The output ranges are also staggering like nano-amps to kiloamps and the same for voltages.This special covers the features and design aspects of power supplies.ContentsBasics Battery ManagementWhat to be aware of when using (Lithium) batteries.

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...
