Photonic Integrated Circuit Technology Photonic Integrated Circuit (also known as PIC), is a complex integrated circuit which incorporates a lot of optical devices to form a single photonic circuit. The main difference between a PIC and an Electronic IC is that PIC is analogous to an Electronic Integrated Circuit. Many optical devices like optical amplifiers, […]
3-D Technology Television has been one of the biggest entertainments since its invention. From its evolution in black and white format, the television technology has later developed to bring colour visuals in CRT displays and later LCD, LED and also Plasma. Nowadays we can get TV’s that is almost 61-inches wide and that too with

Introduction Since the early 70’s video games have been a great entertainment for all of us. With the recent boom in technology, computer graphics has been so advanced that graphic games are being introduced into the real world surroundings. The photo reality is mind boggling to such an extent that you feel that the games
We have always thought of aeroplanes as the fastest mode of transportation. As it travels thousands of miles in an hour we do not mind the flight delays and also the risk in flying. There is no other alternative to planes that can travel such a great distance in minimum amount of time. Buses, cars,
The “Universal Product Codeâ€, also known as UPC Bar Code can be found in almost all packages that you buy from department stores, grocery stores or any other stores. In this post we will discuss on where these codes come from and their actual use. You can also go through the topic Invention Story of
We have seen the use of facial recognition technology in many movies. A photo of the person to be identified will be obtained from some hidden camera. It will then be run in through the police database so as to find a match with their existing records. At last a match will be found and
Overview Direct to home technology refers to the satellite television broadcasting process which is actually intended for home reception. This technology is originally referred to as direct broadcast satellite (DBS) technology. The technology was developed for competing with the local cable TV distribution services by providing higher quality satellite signals with more number of channels.
Almost all the electronic circuits mentioned in this site are designed and built on a PCB board. But you cannot build these electronic circuits if you do not know the basics of soldering. If you do not know to solder well, the solder joints will not be perfect and thus the circuit will have serious
“] Electronic Ink [E-ink We have seen the working of electronic displays like Liquid Crystal Displays, SED TV’s, and Touch screen technology and so on. Even though we rely mostly on monitors nowadays we must not forget the fact that the basic display mechanism is paper the early 105 AD when the Chinese invented it.
We tend to store all photos digitally rather than keeping a hard copy of them. Whenever we need to see them or show it to our friends, we take it from our mobile and show them. All we do is waste more of our digital space. There is nothing satisfactory like watching and enjoying our
For the past few years fingerprint scanners were considered to be a very costly and high end technology. We have seen it only in thriller and sci-fi movies. But now, these devices have been popping up in almost all places like offices, police stations and also our laptops. You also get to buy fingerprint USB
Nowadays, there are a lot of touch screen monitors available in the market. They are made available in displays for computers, personal digital assistants, mobile phones and video games. A touch screen contains a visual display area which can be sensitive to the touch of our finger or other passive components. A touch screen
A strain gauge is a device that is used to measure the strain that occurs in an object. The device was invented in the year 1938 by Edward E. Simmons and Arthur Ruge. The device is still being used in many electronic circuits mainly as the principle sensing element for sensors like torque sensors, pressure
What is a Wheatstone bridge? A Wheatstone bridge is an electrical circuit used to calculate an unknown resistance with the help of a bridge circuit. For this, the two legs of the bridge circuit are kept balanced and one leg of it includes the unknown resistance. The Wheatstone bridge principle is similar to the working of
In my earlier posts I have already explained the working of Charge-coupled devices and its application as an image sensor. Recently, most of the scanners and cameras have introduced a new image sensor called Contact Image Sensors [CIS]. Working of Contact Image Sensor Contact Image Sensor is one compact module consisting of three sub-systems. They
What is a Scanner? A scanner is a device that is used for producing an exact digital image replica of a photo, text written in paper, or even an object. This digital image can be saved as a file to your computer and can be used to alter/enhance the image or apply it to the
Here we are going to look at how a DVD player works and the essential components for its working. Parts of a DVD Player The DVD player is not only used for playing the data present in a DVD, but also to write the content onto a DVD. To know this process it is essential
After the invention of the Digital Versatile Disc [DVD], the true digital sound effect and high clarity video effects were brought to all homes. But the hunger for high-definition videos and audio along with a high-capacity storage disc led to the invention of the Blu-ray Disc [BD]. They have the same capabilities of a DVD,
What is Flexplay DVD? In most foreign countries, people rent a lot of DVD’s from the shop. All you have to do is watch the movie and return the DVD back within the agreed time. But, if we are pretty much unorganized, we tend to forget about the DVD. This is where the DVD rental
What is a DVD? A Digital Versatile Disc/Digital Video Disc [DVD], is an optical disc storage medium like a compact disc [CD], but with greater data storage and high quality audio and video formats. The clarity, when comparison with a CD is almost six times higher. A DVD can be termed in different ways according
In the blog post on fuel cells I have explained the way hydrogen and oxygen react to produce electricity with water as a by-product. There also some disadvantages with this method. The problems include the improper storing and distribution of hydrogen. What is a fuel processor? When comparing a hydrogen fuel cell to that of
What is a Fuel Cell? Fuel Cell is an electrochemical device that is used to convert an open source fuel into electricity. An electrolytic process has to take place inside a cell in which there is an open source fuel [hydrogen] and an oxidant [oxygen]. Both the fuel and oxidant reacts in the presence of
Sometimes you may be unable to find a particular inductor the market. This is actually a problem faced by most of the electronic hobbyists and the problem becomes more serious if your project is RF related. The inductors required for RF circuits (antenna, tuner, amplifier etc) are almost impossible to find in the market and
