In this post I have explained what a supercapacitor is, how closely similar or different to an ordinary capacitor, where it is used and we will be doing comparison between batteries and super-capacitors to find out which one of them is superior. Let’s understand the basics of an ordinary capacitor. How Ordinary Capacitor Works A […]

How Mosquito Traps Work
Mosquito and other forms of fly trap mechanisms work by making use of luring techniques for attracting the insects, which involve carbon dioxide gas, body odor simulators and ultraviolet lights. These traps become very useful in areas which may be highly infested with mosquitoes, however due to its high costs such traps are not very […]
How Flex Resistors Work and how to Interface it with Arduino for Practical Implementation
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 […]
