With the development of phone industry, the need of manual controls in camera is also increasing. Let's take a look on the manual controls in a mobile camera. To take good pictures you first have to know about 'Exposure Triangle' (ISO, Shutter Speed and Aperture & Exposure). ISO ISO level controls the sensitivity of camera to light. At lower ISO level the camera captures less light & at higher ISO level the camera captures more light. So, putting ISO level higher while taking picture can help to take brighter pictures in low light conditions, but it will cost you some extra noise. You should know that taking pictures in high ISO level puts the aperture of the camera opened for a bit long time to capture more light. So, it can produce blurriness while taking picture of moving bodies. But, if you are taking picture of still bodies, you always can use the trick to capture more light. When you want more details you should go with lower ISO level. But...

LeEco and Coolpad worked together to make a phone which breaks the limitations in the field of specifications according to price. At first let's go through the specifications: Display:  5.5 inch Full HD display with 1080×1920 resolution & ~401 ppi. Processor:  Qualcomm Snapdragon 652. RAM:  3 / 4 GB. Memory:  32 / 64 GB internal. Camera:  Dual 13 MP rear camera (f/2.0) & 8 MP front camera (f/2.2). Battery:  406 0 mAh. So, specification wise the phone is awesome. Specially the dual cameras. No company offers dual cameras in that price bracket. The phone is great in design with it's metal finish, performance is perfect with the Snapdragon 652 & Adreno 510 GPU. Battery is large, so no issues will be there. Looking at the price just ₹13999 according to the specifications it offer, it's a must buy phone. The phone will be available at  Amazon  from 5th December, 2016 in India.

Many dreams of past has become reality yet, as for a super transmitter in our pocket which helps us to communicate with anyone on our planet, we can map human genome now or gather the whole world's information in our fingertip any time. But somewhere flying car is missing. History of flying car: Ted Hall was the first aeronautical engineer to introduce the first fully functioning flying car with Convair (a major airplane manufacturer of that time). The car was a combination of road car and attachable wings. The prototype had a total of 66 successful flights. But a crash in 1947 during landing shut downed the project as well as the dream of Hall. Today's actual, working & flying prototypes: The companies Terrafugia, AeroMobil and Moller International have their own such prototypes. So, yes there are flying cars which work really effortlessly. Then why flying cars are not for mass yet? Humans are horrible drivers, that's the reason....

Researchers at Binghamton University in New York created a Bacteria Powered Battery. The researchers said their aim is to make batteries will run for week with a little amount of bacteria rich liquid. They used  a piece of chromatography paper and a ribbon of silver nitrate under a layer of wax. The  anode was made of a conductive polymer on the other half of the paper and a reservoir held bacteria-rich liquid. The cellular respiration powered the battery. The batteries expel 31.51 mW at 125.53 mA with six batteries in three parallel series and 44.85 mW at 105.89 mA in a 6×6 configuration. So, how the batteries will be used? Yes, not to run your car or even phone. But researchers believe these batteries can run glucose sensors, pathogen detectors & can keep small electronics alive for weeks.

iFixit gives a award every year to the most repairable phones. This year they gave it again. Which phone won that? 1. Yes, no doubt it's LG G5. The modular design of the phone makes it highly repairable. The phone scored 8/10, so it's comparably easier to fix it's internal parts as well. 2. The next place goes to Google's Pixel Duo (7/10), but it's hard to open the phone without breaking the display. 3. Next place is for the Apple iPhone 7 & 7 Plus (6/10). Repairing the display & battery of iPhones are easier but other parts are hard to repair at home. The phone requires 4 different types of screw drivers. The most popular phone, Samsung Galaxy S7 & S7 Edge got the last place (3/10). Glue is used more over screws in the phones, so, it's very hard to open the phone at home. Samsung Galaxy Note 7 is in the upper place of S7 (4/10), but it's banned now. But does repairability matters? I think no, cause most people takes t...

Acer pulls out of the world's second largest smartphone market. But why? 1. Acer India's Managing Director Harish Kohli said that Indian market is more about price centric. Affordability surpassing functionality. For the government's make in India initiative larger brands like Samsung, Apple as well as Acer is finding it harder to compete in the market against brands like Huawei, Xiaomi. Because those big brands are not manufacturing phones in India, the price of those phones rising high. 2. For Acer it failed to take the advantage of unique tradition of Indian smartphone market, the Flash Sale, as Huawei, Xiaomi, Vivo and other successful brands are taking. 3. More over finally 4G is replacing 3G in India and for government's Digital India initiative, the youths of India is rushing towards smartphones. And that's why so many brands from all over the world are entering in this market, making competition so hard, specially the Chinese companies. So, final...

Hyundai is known for making reasonable quality cars in reasonable price. Now the company is trying to do the same in exoskeleton industry.

HRL: It's a exoskeleton designed for peoples with 64-71 inches long legs and having weight less than 250 pounds. There are 20 sensors which helps the body to move. The exoskeleton is consisted of 6 50:1 reduction gear actuators, 2 pelvic actuators rated at 224 pound feet of peak torque with 60° range of motion, 2 hip and knee with 112 lb-ft peak. The exoskeleton can walk at a default speed of 1.5 mph. This device will be very helpful for paraplegics. This can help the peoples suffering from spinal cord disease to walk again. WEX: This exoskeleton will help peoples to lift weights. The exoskeleton is consisted of 1 single actuator with 56 lb-ft peak torque...
