1-05-2008 | As we already wrote in the December 2007 article, with a special control circuit you can transform an ordinary kitchen oven into a handy SMD...

1-07-2007 | A microcontroller produces a PWM (pulse width modulated) digital output signal which is filtered by a low-pass RC filter. Although the PWM s...

1-06-2007 | Like it or not, the microcontroller has become an indispensable part of electronics. However, there are still people who know very little ab...

1-04-2007 | Small solar systems have a lot to offer where mains power is unavailable. Installing standalone systems is by no means difficult, using eith...

1-04-2007 | Electronics moves with the times. Over the years the options available change and there are ever different solutions to realising a certain...

1-04-2007 | Circuits that convert a DC supply into a 50 Hz AC supply are called inverters. Commercial units are notable for their small size, high effic...

1-03-2007 | Hard water is still the cause of all sorts of problems, in spite of the fact that standard tap water these days is (partially) decalcified....

1-07-2006 | Current designs of slave flash units are, in the opinion of the writer, too complicated and may be simplified without any problems and witho...

1-07-2006 | The debate still goes on as to which are better, valves or transistors. We don't intend to get involved in that argument here. But if y...

1-07-2006 | The circuit described here is eminently suitable to indicate the capacity of a battery. We use a cheap electric clock for this. By connectin...
