In 2013, the Department of Energy (DOE) dedicated approximately half of a $140 million research institute for power electronics to GaN research, citing its potential to reduce worldwide energy consumption. Now MIT spinout Cambridge Electronics Inc. (CEI) has announced a line of GaN transistors and power electronic circuits that promise to cut energy usage in […]
General considerations: There are several types of dimmers generally available. These are used for resistive, and inductive loads, such as incandescent,cold cathode and low voltage (inductive) lamp sources. Note that not all electronic transformers used for low voltage lamps are suitable for dimming by Triac or Thyristors dimmers. In case of Thyristors you need

Still more noise and vibrations and in extreme case even a total malfunction – this is a typical “end” of the fan after a long-time operation in a dusty or corrosive environment. In a usual dry and relatively clean environment, this scenario is not that dramatic and high-quality fans hold on to work for many
Have you ever seen a fan resistant to dust and water Continue Reading
The Intel® RealSense™ gesture camera represents another foray by Intel into the consumer products space. The camera has been incorporated into the Lenovo ThinkPad Yoga 15. Intel disclosed at IDF14 that the device is formed using three components: a conventional color CMOS image sensor camera, an infrared images sensor, an infrared light projector (the main focus of
Do you know a situation, when a seemingly usual thing is fact not that usual… Whether it´s a car with a hybrid drive or a lot of devices which we meet every day – usually in every segment can be found something “inconspicuous” but in fact unusual and exquisite. This is exactly the case of
I have been an electronics hobbyist for many years and have always stuck with through-hole components when making a project. However as time goes by, not only are more and more components are becoming available only in SMD (surface mount device) but also more interesting projects are also SMD based. There are several options for
Primeiro imprimia o desenho da placa numa folha de acetato. Essa folha era colocada por cima de uma placa foto sensível e colocada sob luz UV durante uns minutos. De seguida essa placa era submersa numa solução com soda caustica para retirar a pelicila foto sensivel que ficou “danificada” com a luz UV. A placa

When working with discrete JFETs, designers may need to accommodate a large variation in device parameters for a given transistor type. A square-law equation is usually used as an approximate model for the drain-current characteristic of the JFET: ID=β(VGS−VP)2, where ID is the drain current, VGS is the gate-to-source voltage, β is the transconductance parameter,
Tiny Board has been designed around LV8772 IC from On-Semi. This driver is capable of micro-step drive and supports 4W 1-2 phase excitation. It has Low on Resistance with motor current selectable in four steps. The board is equipped with unusual condition warning LED and input Pulse Monitor LED. It is most suitable for the
LM2596 based step-down DC-DC converter modules can be bought on eBay quite cheaply for around a dollar each. But how do they perform? Is it safe to use it to power your design? Let’s find out. According to TI’s website, these LM2596 step-down (buck) regulators are sold for $1.8 each for a quantity of a
