what is E-Paper? How it works?

E-Paper or Electronic Paper Display is pretty much similar to an ordinary paper. Then why E-Paper??

There are a lot of advantages with E-Paper, when we compare with ordinary paper ink, it can be electrically refreshed and written upon millions of times.

E-Ink takes advantage of interactions between computer processors and charged black and white particles. Unlike traditional displays like LCDs, LEDs etc… These E-Papers have an advantage of more readability, are flexible and these use very low power .

To get all these advantages together there are a few compromised features like low touch screen capability and less responsive than comparable LCD screen devices. E-Paper manufacturing companies are working to overcome these disadvantages..

The Electronic Paper technology is very futuristic and has a high potential in reducing the usage of paper indirectly saving the environment by not using thousands of trees for the manufacture of paper. E-Paper only use a limited power and can store thousands of books in a single portable device. This means you almost have a whole library in your hand.

After knowing all these interesting and amazingly useful advantages, you must be curious to know about the working of this E-paper right!

Firstly, There are two popular companies manufacturing E-Paper “Electronic inks” – E Ink and “Xerox”.

The e-ink looks very similar to normal ink but it has millions of tiny microcapsules also known as cavities, and are filled by an ink substance. There are pigmented chips or balls there balls are actually the colours that are displayed on the screen. Let’s say white and black. These ball are with a negative charge floating inside the microcapsule.  The ink would cover the entire page and the page is made out of some kind of ultra-thin plastic separated by cells that resemble the cells on graph paper.


These cells are like pixels on a computer screen and each and every cell is wired to the micro level electronics embedded in the page made of ultra thin plastic. Using the basic concept, positive attracts negative or unlike poles attract, these microelectronics would then be used to apply a positive or negative charge to the microcapsules to create the desired text or images. For example, let, all the black balls are negative and all white balls are positive, then when a positive charge is given then, as per the instruction the black balls appear on the screen accomplishing specified task of presenting an image or a number etc…

Likewise, when an electrical charge is applied to the microcapsules, the chips will either rise to the top or be pulled to the bottom. When pushed to the top, the chips make the capsules look white; when they are pulled to the bottom, the viewer only sees the dark ink. Patterns of white and dark can then be created to form words and sentences.

Even more colours other than white and black are also coming to E-paper. There are plenty of gadgets which take the advantage of E-paper like Yotaphone 2, Pebble smart watches, Amazon kindle and also there are many stores which use e-paper to display product prices and other information instead of LCD and LED screens…

This has a lot of scope for development in the coming years! Let me know what you think!

Google Project Ara( An innovative piece’s’ of smart phone)

All the projects that Google is working on, like Project Ara, Project fi, Project Soli, Project wing, Project balloon, Project Tango and many more are super cool.

In my view this year Google I/O 2016 was mostly about AI and VR. Last year I have read about “Google Project Ara” and that really freaked me out. Now let’s see what actually is Project Ara.

Google Project Ara wants to do to hardware what apps did to software.


By creating a phone that can have each component changed, all the main components are interchangeable via modules that click in and out, attaching via electro permanent magnets.

Google believes it will drive down hardware pricing while allowing users to pick and choose what they want. That’s what Google’s Project Ara a modular smartphone aims to do. No need to buy a new Smartphone due to some damage just change the respective module. At last we can say only one thing that it’s a flexible platform suitable for everyone, everywhere and any time. It allows developers to be able to create modules for its Ara device.

So, let me know what do you think…

CES 2016!!

CES never disappoints us. In case you don’t know what CES is. Well… Every January we get to see future, literally the future of technology at CES (Consumer Electronics Show).

As usual, there are so many new gadgets and technologies around. In my view this CES was all about Internet of things( learn more about it here Internet of things ) , Drones, VR’s( a new htc vive, learn more about the previous vive here HTC VIVE ), Pixels(TV’s), a few cars, a special place for Benz concept self driving car( click here to learn more Benz) and a plenty of new technologies.

A real special place for EHANG 184, human sized drone. Check out the video below.

I didn’t actually experienced CES. So, here are a few trusted YouTubers showing a few technologies at CES 2016;)

What’s a DSLR? And how to use it?

Before getting into the usage of a DSLR, let’s see what actually DSLR is and what it does?

In a DSLR (Digital Single Lens Reflex) image you see bounces up to the viewfinder. It passes through a focusing screen and a condenser lens, and then reflects off of a prism’s walls to reach your eye. This allows you to see exactly what the lens sees through the viewfinder. Have a look at the image below.


The main differences between a point shoot camera and a DSLR are , the DSLR will have much better photo quality and response, an ability to change lenses like telephoto lenses, wide-angles, fisheyes and many more.
Well… Now a days we even get to try these lenses as an attachment to our mobile phones too;). I have recently bought these lenses and these work amazing.


How to use a DSLR?

I know it’s actually more dumb to write about the usage of an instrument than to read..;) So here’s the video on how to use a DSLR..

The main basic and main functions of a DSLR on which it works are ISO, SHUTTER and APERTURE.

->”Shutter” speed is responsible for motion blur. This is often seen in many pictures of moving objects where the background goes blur.


->”ISO” is responsible for the sensitivity.


->”Aperture” is responsible for the depth of the field.


All these three functions are interrelated. Now let’s see all these functions on a DSLR.


Thanks for reading… So, let me know if this was useful.



A pen that draws in 3 Dimensions!!

Yes, you read it correct, we have seen 3D printers for a while now (learn more about 3d printing here 3d printing), but now we are gonna talk about something which can literally draw in 3D.

The video above explains it everything!! 3Doodler is the world’s first 3D Printing Pen. Using ABS or PLA plastic (the material used by many 3D printers), 3Doodler draws in the air or on surfaces. A 3D pen doesn’t need any computer.

How it works?


When we start to draw, the pen extrudes heated plastic, which can be moulded and at the same time rapidly cools and quickly hardens to a strong structure.

A 3D pen allows us to draw above the paper providing an unlimited space for imagination and designs.

Now, many companies are manufacturing these 3D pens.

So, what do you think about this?

How were the PYRAMIDS built?

Pyramids are one of the most extraordinary constructions of the ancient world. Since ages we were trying to find out how these pyramids were constructed and how they did manage to pile all those heavy stone. We had many theories too.. But in 2014 Physicists found the answer!

So, the recipe was simple water and sand! The ancient Egyptians who built the pyramids may have been able to move massive stone blocks across the desert by wetting the sand in front of a contraption built to pull the heavy objects.

Physicists at the University of Amsterdam investigated the forces needed to pull weighty objects on a giant sled over desert sand, and discovered that dampening the sand in front of the primitive device reduces friction on the sled, due to which the Egyptians were able to move heavy rock each weighing nearly ton.


But the proportion of water and sand is important. “If you use dry sand, it won’t work as well, but if the sand is too wet, it won’t work either,” Bonn said. “There’s an optimum stiffness.”

The picture below was actually an Egyptian painting explaining the construction of a pyramid, but until now it was mistakenly interpreted to some other painting explaining water purification.



And yeah it feels good to be back!!;)

What’s Li-Fi? How’s that 100 times faster than Wi-Fi?

Scientists achieved speeds of 224 gigabits per second in the lab using Li-Fi!! This technology changes everything about the way we use the Internet.

And now, scientists have taken Li-Fi out of the lab for the first time, trialling it in offices and industrial environments in Tallinn, Estonia, reporting that they can achieve data transmission at 1 GB per second – that’s 100 times faster than the Wi-Fi used on this day.

Let’s see how this thing works?


The technology uses Visible Light Communication (VLC), a medium that uses visible light between 400 and 800 terahertz (THz). It works basically like an incredibly advanced form of Morse code – just like switching a torch on and off according to a certain pattern can relay a secret message, flicking an LED on and off at extreme speeds can be used to write and transmit. These flicking light falls on a receiver which interprets the data (interpret in the sense the particular number of blinks per second has a significant data like a number or a word)

And while you might be worried about how could we feel comfortable with all that flicking, don’t worry – we’re talking LEDs that can be switched on and off at speeds imperceptible to the naked eye.  The frequency will be extremely high.

There are so many advantages with Li-Fi over Wi-Fi. One of those advantages is, the data will be secure, unlike Wi-Fi where the radio waves passes through walls, in Li-Fi the light cannot pass through walls so data cannot be accessed by anyone else the other side. Which also means there’s less interference between devices.

Don’t get hurry searching the internet to order a Li-Fi connection;). Our homes, offices, and industry buildings have already been fitted with infrastructure to provide Wi-Fi, and ripping all of this out to replace it with Li-Fi technology isn’t particularly feasible, so the idea is to retrofit (add to something that did not have it when manufactured) the devices we have right now to work with Li-Fi technology.

If you wanna learn more watch the video specified above, where the man who invented Li-fi explains and demonstrates what Li-Fi actually is.

So, let me know, what do you think.


Biodegrading plastic by bacteria!!

One of the main problem for our environment is Plastic, which is not biodegradable. The only thing we do with the left over plastic is burn them or dispose into oceans.

 As we know we produce plastics through oil. Well… Again that’s one of the most precious source to create energy. Researchers predict that the oil required to produce 9 normal sized plastic bags can be used to run a car up to  1km. But at the same time we are bound to the  productivity delivered by the plastics.

There are something called Phthalates in plastics. These phthalates are very harmful, they can cause cancer. Many of the oceans now a days are filled with these phthalates and cause the marine animals to die. In recent years scientists were experimenting on various bacterias which consume these phthalates.

So, scientists have now discovered that bacteria from the guts of a worm known to munch on food packaging can degrade polyethylene, the most common plastic. Reported in the ACS journal Environmental Science & Technology, the finding could lead to new ways to help get rid of the otherwise persistent waste, the scientists say.

The researchers turned to a plastic-eating moth larva, known as a waxworm. They found that at least two strains of the waxworm’s gut microbes could degrade polyethylene without a pretreatment step. They say the results point toward a new, more direct way to biodegrade plastic.

This topic was inspired by one of my friends question…

So, let me know what do you think..

Renewable energy sources!!

Renewable energy sources are the naturally occurring sources, used to create clean energy. We have invented many different ways to create clean energy through renewable energy sources. One of the most important reasons to start using some alternative energy sources to create energy is that, In near future we may run out of the most extensively used fossil fuel and it is more likely to replace fossil fuels with electricity which can be obtained through various renewable energy sources.Unlike the traditional renewable sources like solar energy and wind energy, let’s see some of the developing and futuristic renewable energy sources.

Tidal energy – Tidal power is non polluting. Although the tidal power is variable due to various factors like gravity they are reliable and predictable and their power can make a valuable contribution to an electrical system which has a variety of sources. Tidal electricity can be used to displace electricity which would otherwise be generated by fossil fuel (coal, oil, natural gas) fired power plants, thus reducing emissions of greenhouse and acid gasses. First time ever in the world there is a wave-powered desalination plant that provide clean drinking water.

Piezoelectricity- There are certain materials called Piezoelectric material, which on applying mechanical stress produce electricity. This concept can be used in various ways like fitting a peizo electric material in a shoe, where there is always some pressure applied while walking. The Piezoelectric material is composed of equal number of electrons and protons so, the charges cancel out giving no net zero charge. As we apply pressure on this type of materials, the charges get out of balance and they end up giving some voltage at it ends. To know more check out my article on piezoelectricity here Piezoelectricity

Quantum dot solar cell technology– This might sound familiar to solar energy, like obtaining electricity through solar panels, but this isn’t that similar. Quantum dot solar technology allows highly efficient solar panels to double as transparent windows. In these devices, a fraction of light transmitted through the window is absorbed by nanosized particles (semiconductor quantum dots) dispersed in a glass window, re-emitted at the infrared wavelength invisible to the human eye, and wave-guided to a solar cell at the edge of the window. If this technology still develops then we might see every sun exposed window covered with this Quantum dot solar panels.

Hydrogen power – Hydrogen fuel is basically an alternative fuel that has potential in dramatically decreasing the energy consumption of vehicles. It can be obtained by burning H2 and O2, which in turn could produce electricity and heat. The by-products in this process include H2O and small amounts of nitrogen oxide. Since the production of Hydrogen Fuel produces non-pollutants, many experts believe that Hydrogen Fuel could be an eco-friendly alternative to our current energy sources. In addition, Hydrogen Fuel can also be commercialized.

Fusion– All the sources we have seen above were perfectly possible and practiced in real life. But this particular source is very hard and scientists are working to sort out a solution. So, for now this is still a theory, let’s see. Unlike fission reactions, fusion reactions does not give out any nuclear wastes. Scientists described fusion as “trying to put sun into a box”. Well… This is extremely tough to do this. In 2013 at Lawrence Livermore National laboratory in USA did an experiment on fusion where for the first time a fuel capsule gave off more energy than was applied. Many countries are experimenting on fusion to create electricity which may serve with power for years.

CONCLUSION – So by using renewable sources we will be able to create eco friendly clean energy. We are depending more on fossil fuels which are limited and cause pollution. So, by replacing them with electricity created by renewable sources is extremely advantageous. Even many automobile companies are trying to make more efficient automobiles running with clean electricity.

This was actually a part of my paper presentation, hope yo got cool info…. And do expect few articles on more renewable sources in near future…
