Balloons that spread internet

Balloons that spread internet hmmm the topic sounds interesting ryt?? Yah its true in near future balloons will be used to broadcast the spectrum for internet. This is an initiative by Google carried under project named 'project loon'. The concept of this project is, helium balloons will be launched to high altitude and from there they will broadcast the internet. So the altitude is about 10km above the earth, the atmospheric level is called stratosphere the layer where aeroplanes fly. There will be several balloons and they will be communicating with each other. The balloons will be controlled by a base station and the signal will be received by antennas in homes like a WiFi actually its a WiFi. The aim of this project is to provide internet to those regions where internet is inaccessible by any means like villages, jungles, mountains etc etc. This will also help in providing internet during natural disaster. Another benefit from this project is medical facilities, weather forecasting will be available to the persons who are in these remote areas. So the development of this project started in Canterbury, New Zealand on June 2013. It was a pilot project. So they started with using simple weather balloons and transponder attached to it but after launching they found that it cannot sustain for longer duration as it explodes. So they developed better materials for balloons so that is can sustain in that level at least for a month. Then the next problem can with stability. There are different patterns of wind flow in that level and the stability was a question mark without a closed loop control system. So they attached an impeller with the balloon so that it can blow in air and a valve so that it can expel the air inside. So when the air is blown inside the balloon rises and when air is blown out the balloon descends. The stability of balloon can be controlled with ascending and descending because it is found that is stratosphere two layers of wind flow in opposite direction so by ascending and descending the stability can be maintained. Now this balloons are solar powered and the temperature in the stratosphere fluctuates from -3 to 29.6 C. The problem that arrived is at such a low temperature Li ion batteries do not give there optimum performance so the solution was using the heat generated form the electronics components and keeping the entire setup in a insulated box wrapped with insulating sheets developed by NASA. So with is the temperature problem is solved and the battery gave great performance.There will be large number of balloons revolving around the earth like small balloon satellites and providing continuous internet due to continuous circulation of balloons. Another major problem faced was signal reception, the balloon while travelling rotates about its own axis so we get bipolar signal the was solved by using two antennas,
one will receive signal when the wave is in x-direction and the other when it is is y-direction if we use a single antenna then we wont get any signal. Recently Google as leased an hanger in California for its second phase of its research and testing. This is any excellent project for the betterment of humanity. If this project succeeds the world will be better connected. Thanks to Google for seeding these kind for projects and making our lives easier.

Which ones better Xbox One or PS4??

This is a hell of a task of choosing between Xbox One and PS4. The two gaming consoles Xbox One by Microsoft and PS4 by Sony were launched simultaneously to entice the world of gamers. These to were best in there respective field when they were launched but after the launch the two consoles showed many technical problems some were like blueray disc not functioning, updates taking longer time to load and many more. But with due coarse of time the problems were solved new titles were launched and the popularity grew. But now the scenario is Microsoft's Xbox One is loosing grip in this cut throat competition. Reviewers say PS4 is graphically sound and is simple to use where as with new interface in Xbox One they its bit complected though in terms of media entertainment no one compete with it. Talking about hardware configuration both have same number of cores but Xbox One uses two of its cores apart form gaming. PS4 has the latest DDR5 ram where as Xbox still uses conventional DDR3 RAM but is has an ESRAM which provides a bridge between graphic card and RAM reduces the usage of CPU. This ESRAM is the major culprit for not delivering full HD resolution to some games like COD Ghosts and many more, there native resolution is 720p where as this is not the case in PS4, all the games run with full HD and thus it's graphically ahead of all the consoles. So for hardcore gamers definitely Xbox One sucks but for normal people who want everything for them Xbox One rocks. With the new update the Xbox One has upscaled the resolution to full HD but sill the native resolution remains 720p and it dose not look that great. The developer are unable to utilize the ESRAM properly but in near future if this is fixed the Xbox one will be Mecca for the gamers.

Project Ara the savior

When Google sold Motorola to Lenovo, few engineers at Motorola stepped back to work for Google. Then those nerds started working under a project named 'Project Ara' in Google. This is a amazing project which aims to provide internet connection to those unfortunate earthlings who are not able to own a smart phone due to economic constraints. I called the project a savior because this not only aims to provide internet to 5 billion unfortunates but to a person who is tired to changing smartphones every year. This is possible by creating a endo skeleton which has many slots with magnet in it and those slots can be filled by chips for example one slot for camera next for processor and so on and the magnets just hold the chips in the required position so that it does not slides away. The benefit we get from this concept is we can upgrade the component that we want to for example I just want to upgrade my phones camera to higher megapixel, a present smartphone cannot but with this project we can. So with this project we need not to change our entire phone for at least next five years. This can be compared to a pc in which we can upgrade the components that we want to and the best thing these smart phones costs less and its very economical as it is priced above the crossover point. So its a revolution in smartphone technology and now we will be able to get third party hardware developers which now no more require the specification from the core companies who make smartphones like htc apple etc etc. Like software we will get hardware too ie highly customizable. There are few issues with this smartphones like its quiet heavy and sort of distorted. But the project member say its gone be even great next year because now the project is under development stage and still the mdk (module development kit) is not open to the developers. So lets hope that this project serves it purpose.

Day 23

I am updating my blog after many days, so u all must have judged my character by now. Whenever I start a work I completely give my dedication to that and i work on that painstakingly but as soon as my mind gets a hints of laziness then my motivation drops instantaneously to 0. So I have been dealing with this problem since childhood and I used to often as to superpowers that why is this happening with me. For this kind of attitude I have been facing failures all the time, my accuracy is decreasing and many other troubles are happening in my life. My friend and I always plan to do certain kind of activity, but it never comes out of the pen and paper. We have many innovative idea but the problem we don't have the motivation to fulfill it and show it to the word. We are trapped the cycle of typical Indian higher education. We have become slaves of our evil mind. Awaiting for a sunrise in our lives which will eliminate the darkness, so that  ideas spread in the world like a wild fire. Again I will update my blog after a long gap when my body will get a hint of motivation and fire.

Day 21

Today I had a wired dream in afternoon. I along with my junior who is recently studying in Delhi made a visit to our old school where I read till matric. First I went to a class may 4th or 5th grade and I saw there my maths teacher who taught us in 10th. He fail to recognize me. I then got angry a scolded him like any thing and also made him responsible for low marks in 10th because of his low sending in maths practical. After scolding I went outside and asked my junior that will cause me any harm in my career and he said no, so I became relaxed. After that I woke up due to extreme heat and humidity in our room. Then I sat and thought about my old school and became very emotional. I thought what would my teacher think of me if see them this vacation. O don't think I will ever go to that school and meet my old teachers. I really wish to......

Day 21

I have been not writing blog since my exams were over. The reason is I bought my laptop and I am leaving in a virtual world now. My day starts with going for lectures and labs in the first half after I am back from the college I eat my launch and take rest. Then at sharp 3pm I wake up along with my room-mate to go for CATIA classes at CTTC in a bus. After the class gets over we walk to our hostels and then get glued to our computer screens and enter into a virtual world. I find the virtual addictive and get so involved into it that I forget where I am. I write blogs when I feel lonely or get saturated from this virtual world. Today I am writing this because today is holiday and I was writing my elec record which is to be submitted tomorrow hence got bored thought of writing my blog. Now a days my mother keeps on saying me to prepare for GATE exam but I have no mood to read. I feel like reading but i fear from my room-mates criticism. I don't know why I am not fearless for this I am loosing lot of things. Why I am not understanding???? God please help me in this matter pleaseeeeeeee.......

Day 20

From now onwards I don't think I will be able to sleep in afternoon. Again my roommate's interference but today it didn't hamper my nap because I had to go CTTC for enquiry about our catia classes which the incharge said to start from tomorrow after registering. Many from our college are deciding to take this course to enhance their academic qualification. My roommate was ironing his clothes in the afternoon he finds time to do all his domestic chores either in the afternoon or in late nights holy crap. Now a days watching big bang theory passing my time gluing to my laptop screen. Yesterday I received the copy of my oth of vayuputras so will read some day. Thinking of taking coaching for gate but let's see how its possible. Again God please give me and my roommates a tension free life because when we are not tensed we perform better except my 9 pointer roommate. Trying to get some sleep.....
