Commenting on the announcement Mr. Hiroshi Takashina, Managing Director, Nikon India said “We are thrilled to enhance our NIKKOR lens line-up with these extraordinary zoom lenses that enable photographers to capture the best images possible from a distance and wide range of angles. These lightweight lenses respond to the demands of hobbyists, photography enthusiasts and advanced amateur photographers looking to achieve best quality images”. He added, “Nikon’s aim is to provide product and services that surpasses the demands of the consumer and in return give them an edge over the others....

This phone comes with a 4.5 Inch display with a resolution of 1280 x 768(WXGA) thus giving you a pixel density of 331 ppi. The display is protected by 2.5 D sculpted Gorilla Glass 3 thus making it extremely resistant to abuse. The display type will be Nokia’s clear black which will give you good outdoor visibility by reducing reflected light from your screen. This display will come with super sensitive touch for nail and glove usage....

One Transistor Electronic Code Lock System Circuit Principle: The main principle of this circuit is that the door lock opens only when the buttons in series are pressed at a time. If any button which is in parallel is pressed door is locked. When all these buttons are pressed transistor switches the relay and the door is opened. In real time these buttons can be arranged in an order to open the door....

The simplest of errors is corruption of a bit i.e., a 1 may be transmitted as a 0 or vice-versa. To confirm whether the received data is the intended data or not, we should be able to detect errors at the receiver. In this tutorial, we will learn about Parity Bit, Even Parity, Odd Parity, Parity Generator and Parity Checker with a practical example and practical circuit. What is Parity Bit?...

The Y axis represents the magnitude and phase angle of the waveform in the form of imaginary quantities and X axis represents real quantities like time period of the wave form. The magnitude of the waveform is generally measured as RMS voltage. So, with phasors, we represent the RMS voltage. Always the phasors rotates counter clock- wise direction along with the phase of the waveform. In phasor complex number representation includes the magnitude and phase angle of any waveform....

The concept behind the working of this project is Multivibrator. So, before going into the details of the project, let us understand the concept of a Multivibrator. Multivibrator Multivibrator are found in lots of applications as they are among the most broadly used circuits. The application can be anything from a simple household application or a complex industrial or communication application. The multivibrator can also work in applications like an oscillator, digital flip flop, pulse generator circuit, timer or it can be even used in generator circuit and lots more....

The most common form of AC supply is sinusoidal wave. The mathematical function describing a typical AC voltage is V (t) = VMax sin ωt. V (t) is the voltage in the function of time. The voltage changes with time. t is the variable time in seconds. VMax is the peak value that the sine wave can reach in both positive and negative directions. For positive cycle it is VMax and for negative cycle it is -VMax....

Combinational Logic and Sequential Logic are the building blocks of Digital System Design. Combinational Circuits include Multiplexers, Demultiplexers, Encoders, Decoders, etc. whereas Sequential Circuits are Latches, Flip-flops, Counters, Registers etc. To understand more about basics of Sequential Logic and all its elements like Clock, Triggering, Synchronous, Asynchronous Circuits etc. continue to read the following tutorial. Introduction Sequential logic circuits are those, whose output depends not only on the present value of the input but also on previous values of the input signal (history of values) which is in contrast to combinational circuits where output depends only on the present values of the input, at any instant of time....

Once you have bought this device, you can get this offer redeemed within 3 months of the buying period with the help of a promo code, which will be given to you along with the device which you have bought from Aircel. Even if you an existing customer, you can use that promo-code and avail that offer. On this, Anupam Vasudev, Chief Marketing Officer, Aircel, said, “The growth of Indian telecommunication sector is highly driven by emerging new technologies and changing consumer behavior....

Under arc welding, there are also various sub-processes available, namely MIG, TIG, and stick welding. These sub-processes differ from one another in their procedures, benefits, limitations, and applications. In this article, we will have a comprehensive look at stick welding and MIG welding and understand their differences. About Stick Welding Stick welding is the simplest and cost-effective arc welding process. In this process, a consumable flux-coated rod is used as the electrode....

We commonly use temperature control systems in Air Conditioners, Refrigerators, geysers, etc. where the temperature is automatically adjusted as per the input settings. In order to implement a temperature control system, we need a temperature sensor, a controller, and a cooling system. In this project, we have implemented a simple Temperature control system using simple components. The aim of this project is to automatically turn on or off the fan by detecting the surrounding temperature....

Hence, we have shortlisted the best 10-inch tablets from the market for you.

But make sure to keep in mind a few things to consider such as: Operating System: The majority of the tablet options out there usually come with Android OS which is truly the most user-friendly one....

It uses a long, sharp thin looped blade between two wheels that offers control over the cutting process. You can use it for different cutting types that include a miter saw, table saw for rip cuts, and also reduce the board thickness like a thick planer. If you are looking to invest in a new band saw or want to upgrade the existing one, consider the below factors to choose the right one....

A rechargeable hand warmer is a standalone device that produces heat by utilizing electronic charge. The devices are packed with a rechargeable battery and offer decent performance for a longer period of time. Along with that, here are some more important features that you will find in a rechargeable hand warmer: Battery Capacity: Similar to smartphones, the battery capacity is also an important factor for rechargeable hand warmers. Each of these devices are mentioned with the battery capacity in the “mAh” unit....

Quantity: The first thing to consider while getting an RV caulk should be the quantity included in a given pack. This is due to the reason that you will most likely need a lot of caulk in most cases. Thus, almost all RV caulks include 10 oz quantities which should be good enough for most users. Ideal Surfaces: As you would know, there are all kinds of materials used in any given RV in different places....

Also, the headlight bulbs let other people (pedestrians and passengers) and animals on the road notice the vehicle approaching them. Similar to others, they may need replacement over the time as these bulbs burn out, broke, or fade eventually.

Load Capacity: Before getting any kind of suspension for your car, you have to ensure that the suspensions can support the weight of your car. And thus, checking the load capacity rating is highly important. This is due to the reason that air suspensions with a load capacity of 5000 pounds are more versatile than those with a weight capacity of 3000 pounds. Maximum Pressure: A great thing about air suspension is that they are easily adjustable....

Dimensions: You need to check the dimensions of a greenhouse before buying it as it tells you about the amount of space you get inside.
