However, the bass sound notes are lower than 450Hz, resulting in better resonance to a large volume. Hence, the music usually remains confined to a narrow space. Moreover, subwoofers also offer a richer music listening experience to you without damaging your ears a lot. Hence, many people often prefer subwoofers as these are one of the best ways to enjoy music in your home, in a car, or even on the go....

The furnace itself may include a heating element, a blower to circulate the air, and various controls and sensors to regulate the temperature and ensure safe operation. Electric furnaces are known for their efficiency and reliability and are a popular choice for both residential and commercial heating needs. Electric Furnace Parts The main components of an electric furnace include: Heating Element: This is the component that generates heat and is typically made of resistive wire that is heated when an electric current is passed through it....

Buying an energy meter for your home will allow close monitoring of energy consumption in your home. You can use it for multiple applications such as bill management, real-time energy tracking, monthly energy consumption statistics, and many more. But before you decide to buy an energy monitor, make sure that it has the following features. Smart Detection: All electricity devices in your home consume electricity differently. While some require negligible power to run, some devices are solely responsible for an expensive electricity bill....

And, you can also explore the places where an RV will simply not fit because of its large size.

But why blinking LEDs? Blinking LEDs will be the first practical project , that many implement when starting with a new MCU as it is the “Hello, World!” of the electronics. So, without deviating from the tradition, let us blink some LEDs using ARM7 LPC2148. The aim of this project is to blink a set of LEDs connected to the pins of ARM7 LPC2148 so that we can understand how to configure the registers of the MCU and some other basic functions....

The display size of this device is 3.5 Inches and it runs on Ice Cream Sandwich (which has gone really obsolete these days). This phone has been powered by a processor of 1GHz and we are not sure about the manufacturer and the number of cores this processor has.

Introduction Power supplies are an important component in electrical and electronic circuits. They are usually very reliable and can provide good and clean power to the main circuitry. In fact, the life, reliability and longevity of any electronic system is dependent on a good power supply. If a power supply fails for any reason, then the circuit attached to it will be significantly damaged, sometimes beyond repair. For example, one common problem with linear power supplies is the failure of the series pass transistor....

Introduction Up until the late 19th century, the main source of artificial lighting has been by burning of vegetable oil, animal oil, fat and waxes. A wick is used to control the amount of fuel that is being burnt and thus the mount of light it produces. Things changed with the invention of Incandescent Bulb, a source of light that is ‘fueled’ or powered electricity. With the widespread availability of electricity and a significant amount of technological effort into making better lighting systems, modern electricity based light sources come in a variety of shapes, sizes and types for all kinds of applications....

We have brought some great options for under-seat subwoofers based on factors given here: Dimensions of The Subwoofer: As you are going to install the subwoofer under your seat, you need to carefully consider the dimensions of the subwoofer....

Introduction You might have had the experience of seeing a spark or hearing a crackle when you take off your clothes (particularly woolen clothes in dry weather) or when touching a door knob to open the door. The reason for these (and several other) experiences is very simple. When we come in contact (usually, rubbing against) with insulating surfaces, we accumulate Electric Charge. When we touch the door knob or woolen sweater, we are discharging this electric charge through our body....

Facebook is already integrated in our lives with our social network, contacts, chats, events groups, pages to follow and everything else. Today when we logon to Facebook then we can do anything there, literally anything and even if we are searching for something which is not available on Facebook then it will direct us to the Bing Search Engine. Now Facebook needs a phone as a media to fig deep into the personal life of the users and make them totally dependent on Facebook....
