As electronics enthusiasts we may come across many kinds of resistors, from small fixed resistor to high current bulk rheostat. There are humongous classifications among resistors, but here we will focus on a particular kind of resistor called “flex resistor” and learn how it works. As the name signifies a flex resistor is flexible and […]

How Buck Converters Work
The article below presents a comprehensive know how regarding how buck converters work. As the name suggests, a buck converter is designed to oppose or restrict an input current causing an output that may be much lower than the supplied input. In other words it can be considered a step down converter which could be […]
How Buck-Boost Circuits Work
We all have heard a lot about buck and boost circuits and know that basically these circuits are used in SMPS designs for stepping up or stepping down a given voltage at the input. The interesting thing about this technology is that it allows the above functions with negligible heat generation which results in a […]
How Laser Microphones or Laser Bugs Work
A laser microphone is a security monitoring gadget in which a laser beam is used for detecting audio vibrations across faraway targets, which are normally walls or glass of homes or offices. These devices could be applied for eavesdropping with virtually no chance of getting identified or cover getting blown. Laser eavesdropping gadgets, it is […]
Fuel Cells [How they Work]
Fuel cells have the capacity to be the most effective and ecologically friendly power source ever devised. Since fuel cells are able to generate drinking water as a by-product, they are indeed an appealing replacement for traditional power generation. How much more could you want from a source of energy? History Sir William Grove developed […]
How Stepper Motors Work
In this post I have explained about stepper motor. We will be exploring what stepper motor is, its fundamental working mechanism, types of stepper motor, stepping modes, and lastly its advantages and disadvantages. What is stepper motor? Stepper motor is brushless motor; its rotating shaft (rotor) completes one rotation with a determined number of steps. […]
