The Most Interesting and Unusual Applications of LED Lighting
Thanks to LED lighting, nowadays we are able to use smartphones with very well-lit screens, LED monitors and TVs, Blu-ray players, as well as many other technological marvels which are part of our everyday lives. The LED light bulbs use around 80% less electrical energy compared to all other types of bulbs, so this makes them incredibly energy-efficient source of light. Moreover, they are safe…

How to choose bathroom extractor fan
An extractor fan in the bathroom, toilet or another wet room isn’t luxury – it’s a must because of the moisture and unpleasant odors that accumulate making the air unbreathable. Furthermore, over time moisture leads to the growth of mold, which is a source of harmful spores that cause respiratory troubles. Some bathrooms have outside windows that let fresh air in when open. Nevertheless, mechanical…

How to choose a soldering iron (part one)
A soldering iron is a hand-held tool for soldering, i.e. for making a permanent connection between two metal objects using a different metal (solder) that has a lower melting point than the components being joined. Soldering is the most commonly used method of mounting electronic components on PCBs. Choosing a soldering iron for your electronics workshop is a very important step in organizing such a…

Rectifiers. Graetz circuit and Illarionov circuit
Rectifiers convert AC power to DC power. In most rectifiers the resulting output current is not constant but pulse current. Different filters are used for smoothing the pulsations. There are many types of rectifiers. Here are some popular classifications: According to the type of the device – mechanical, thyristor, transistor, diode rectifiers; According to the power – high-power and low-power; According to the number of…

Laboratory power supplies Part I
Power supply sources are among the electronic devices that are most used in laboratories for testing various household and industrial appliances and equipment. A power supply unit can be defined as a source which supplies energy and power. Unlike industrial energy sources, such as hydroelectric power plants, heating or renewable energy, we are going to focus only on power supplies that are used for testing…
