Bigger speaker boxes produce proportionately higher bass effect, this fact is know to all of us. However, bigger boxes are not only expensive, they can be cumbersome and bulky. How about having the very same high bass effect, that a bigger box would provide, from a much smaller and compact speaker enclosure? Sounds strange right? […]

Simple SG3525 Sine Wave Inverter Circuit Explained
In this post we will discuss two methods of designing pure sine wave inverter circuits using 555 IC based SPWM processing. In the first concept we connect the 555 processors directly with the SG3525 outputs and do the sine wave conversion directly at the MOSFET gates. In the second concept we do it externally and […]
How to Sense Current Using Op-Amp: Low Side and High Side Circuits Explained
In this post we are going to learn one very interesting and also very much useful topic that is how we can measure the current which is going through any load by just using some normal resistors and one op amp circuit. We know already that current is one very important thing in every electrical […]
High Efficiency Solar Charger Circuits using Switching Regulators
Solar power or electricity from sun light is so abundant that we can afford to waste it or dissipate it in the form heat. This means that we can use large, high power solar panels to charge batteries with lower power without bothering about how much solar energy is being wasted and how much the […]
12 V to 30 V High Current Boost Converter Circuit [Variable]
In this post I have explained how to make a high current boost converter circuit which will step up a 12 V DC to any higher level up to 30 V maximum, and at an impressive 3 amp current rate. This high current output can be further enhanced by suitably upgrading the inductor wire gauge […]
How to Make Dog Barking Preventer Circuit using High Frequency Deterrence
The discussed circuits are designed to discourage dogs from barking in the selected zone by the generation of a synchronized ultrasonic sound waves in response to a few initial barking of a particular dog. The circuits explained below when correctly optimized will produce a high pitched ultra sonic sound each time it senses a dog […]
