  • Solar Powered Smartphones Without Solar Panels – Coming Soon

    Solar Powered Smartphones Without Solar Panels – Coming Soon

    In a very interesting development, researchers from the UCLA Henry Samueli School of Engineering and Applied Sciences, have created an LCD screen which can charge its own batteries from any ambient light source such as the sun, an incandescent bulb and even its own backlight!

    We took a look a little while ago at How Modern LCDs Work. As you might remember, each LCD has a polarizing sheet that controls the amount of light that passes through any given pixel. These polarizers are very inefficient, and waste most of the absorbed energy. With this new development however, the standard polarizers have been replaced by a polarized sheet made with organic photovoltaics. These photovoltaics convert any absorbed energy, into electricity, thereby increasing the battery life of any device that it is used in.

    The researchers say that they are speaking to manufacturers so that this technology may be incorporated into future products.

  • Micromax Andro A70 Review

    Micromax Andro A70 Review

    The Micromax Andro A70 was one of the most anticipated phones of this quarter, especially in the sub Rs. 8000 bracket. To be honest, at first we thought of it as just a minor upgrade to the existing Andro A60. But as we reviewed this little marvel we began so see a major change in its operation. Lets see why the Andro A70 is our pick for the price range.

    Build Quality and Design

    Reminiscent of the Nexus One’s design, the Micromax Andro A70 is built with sturdy plastics. Nice curvaceous ends make it an extremely attractive design, and very comfortable to hold in the hand. The screen on the front is tough and provides the extra protection required for a touch phone of this nature. The buttons are tactile and easy to use, the overall standard of construction is quite impressive.

    The front of the display is also glass and not plastic unlike its predecessor, Which makes the overall build of the device impressive. The phone is sturdy and does not make rattling noises even when tossed around.

     

    Hardware 

    •   Android 2.2 (Froyo)
    •   Camera Primary 5.0 MP Secondary – VGA
    •   600MHz Processor
    •   3.2 inch Multi Touch Capacitive Screen
    •   Mi – apps –  application store by Micromax
    •  Full Android Market
    •   WCDMA 2100 MHz
    •   HSDPA 7.2 Mbps
    •   Mi-Fi Pocket Wireless Internet
    •   GPS             
    •   Wi-Fi 802.11 b/g
    •   Battery 1450mAh
    •   Proximity Sensor
    •   Gravity Sensor

    Camera and Multimedia

    A surprisingly interesting 5 MP camera with autofocus that delivers exceptionally good pictures. The camera displays great skill when it comes to auto-focus and cannot be tackled down by any other device in this price range. Although colors appear washed out at first but a little playing around with the settings gives a good picture.

    Video on the other hand is simply OK, you cannot expect much from the VGA video capability. A simple tweak, by changing the video quality settings to custom in the camera we were able to get VGA video. If you leave the video quality to high, it captures a much lower resolution video. A sample of the video can be seen in the videos below.

    The Front facing camera, is a simple VGA camera and can be used for nothing but clicking self portraits and video. We tried several times to initiate a camera response from Skype /fring etc, but failed to do so.

    The screen of the Andro A70 is great for watching videos and browsing the internet. It is also a capacitive 2 point multitouch screen, so pinch to zoom works great and with the 3.2 inch 320x480px screen text is crisp and easily read. 

    Speakers are loud and clear when it comes to watching videos or simply listening to music. Overall multimedia experience was satisfactory and a lot more than you can expect from a device which costs only 7500 Rs.

    Phone and Messaging

    No complaints here, the phone call capability was excellent , little or no dropped calls, clear speaker and earpiece. the microphone also pics up sound aptly and delivers to the other side. One thing with mentioning is the number of connection errors faced in process of dialing a number were far more than any other device tested.

    Messaging and emailing has also improved vastly over the previous A60 thanks to the inclusion of the capacitive screen. This makes the device almost brilliant, keyboard is nice and spread out and easy to type on even with relatively large fingers. The keyboard can also be easily replaced with customizable keyboards from the Marketplace, including Better Keyboard. Swype however does not work with the Andro A70.

     

    Internet and Portable Hotspot

    This section is dedicated to connectivity and utilization of the Internet, Data and WiFi. 
    The A70 has a very weak WiFi antenna, and mostly requires you to be relatively close to the router to get a decent signal. This was kind of a let down especially after the excellent WiFi antenna on the Andro A60.

    The Portable Hotspot also fails throughout the board, dropping WiFi and asking for reactivations several times.

    Apart from the above, browsing works great on the A70 especially 3G networks perform as good as high end phones.

    Battery Life

    We were quite impressed with the battery life on the A70, with over 5 hours of talk time, and a good 7-8 of internet usage, upto 3 days of standby, make it an excellent device in terms of battery life. But with Android as an OS, you never know what app you install, suddenly battery life is critically lower than before. Overall great battery , be sure to inspect your apps if you face battery issues.

    Conclusion

    While its an extremely awesome device for its price, it definitely has its ups and its down . With limited WiFi range and useless front camera this device lacks little and gives more. Good things include impressive build quality, a great photo camera, Android 2.2, wifi hotspot, easily root-able ( with possibility of custom rome). This device is a little understated by the company. The UI is much improved and a launcher from the market like ADW launcher can make this device a gem with pinch home screens, and smooth scrolling. 

    The Micromax Andro A70 is a good package for someone who wants to enter the Android ecosystem, or even a good upgrade for an A60 user. This device is also an excellent secondary device for a expensive smartphone. 

    We say go for it!

    The Sony Ericsson Txt Pro is a budget yet spec’d out phone, with a proprietary OS on the device the Txt Pro offers Xperia like UI , without the frills of an Android Interface.

    Build Quality

    Surprising well built for its price, with a spring loaded robust slide mechanism, the device seems up to mark with any premium slider phones back in the day. the overall construction is also quite stable and the device does not rattle at all despite a 2 part design. The soft touch plastic is a great addition to the handleability of the device,and  its extremely comfortable in the hand. The Keyboard is a chiclet style keyboard and has wonderfully tactile buttons.

    Full Review

    Although priced at Rs. 7,500, the phone does not offer too many features. One can get decent Android phones for around that price. So why would anybody consider this phone? Well for starters overly-smart operating systems (read android) require constant attention and care, consume a lot of battery and become the centre of your life. Some people still like to buy phones for their basic abilities.

    The txt pro offers basics with a little bit of add ons , you do get all your social networks included – Facebook, Orkut, twitter and Picasa apps come preloaded. Allowing you to fully utilize the qwerty keyboard for chatting messaging and emailing. The device also features WiFi connectivity , but unfortunately has no 3G. 

    The touchscreen is a capacitive screen and is extremely responsive, the UI is easy on the eyes and  breeze to use. The camera is a simple 3.2 MP fixed focus camera and does not deliver great pictures.

    Our recommendation is that for this price be a little thrill seeking and make the switch to Android, and get a different device, Optimus One, Galaxy Pop, Galaxy 551, Mini, or even the Dell XCD 35. The phones will actually make you happy. 

    This phone (Txt Pro) is extremely loud and an excellent phone, but why buy it when you can get much more.

    Video Unboxing and Review

  • LG Optimus Black Review

    LG Optimus Black Review

    The LG Optimus Black was announced a while back, March 2011 to be precise, but the device appeared on our shores much later in July. People awaited the LG Optimus Black with much anticipation as it offered brilliance on a budget. 

    Does it really stand up to its name? Does it deliver brilliance? Lets Find Out!

    Build Quality

    The Optimus Black is possibly the most well built phone in LG’s stable, only after the 2X. With a slim profile and tapered glossy black accents, the device also has a tough front glass and a brilliant camera. The device is built to last and will not fail to deliver in that respect. The plastic is of superior quality and the device does not rattle or squeak from anywhere.

     
    Name Type
    Operating System   Android OS v2.2
     Dimensions  122mm x 64mm x 9.2 mm
     Weight  109g
     Display Screen  4 inch WVGA IPS LCD
     Processor  1 GHz Cortex A8 Processor
     RAM  512 MB
     Storage  2GB Internal + 32GB Optional
     Camera  5 MP Rear : 2 MP Front (AF)
     Video  720P VIDEO @30 fps
     Connectivity  Wi-Fi, 3G, GPRS, EDGE,
    A-GPS, Bluetooth v3.1 with EDR
     Battery  1500 mAh Li-Ion
    The Price of the Device is about : Rs. 19,800 in the Market

    Camera & Multimedia

    The device features a brilliant 5mp Autofocus camera on the back that does HD video at 720p (watch sample below). The picture quality  from the 5mp snapper is absolutely stunning, the camera focuses with precision and the LED does a wonderful job of eliminating darkness. The camera is also snappy at taking pictures and responds quickly.

    Video quality is pretty great and almost close to what the iPhone 4 has to offer in good light, but kind of waivers in low light.

    The front facing camera is simply superb quality and works just fine with Skype and other video softwares.

    Audio from videos is low, but in game audio and music sounds are loud. The preference file some where needs to be tweaked to output proper audio. the speaker is fairly loud when the audio is proper. But, not as great as we would have like it to be.

    The display is absolutely brilliant with a 700NIT brightness. The brightest display on a mobile device ever, makes the quality of the display that much better, whether indoors or outdoors. The only drawback of a very bright display is low battery life.

    Phone & Messaging

    The earpiece and microphone are great to pick up sound, but one unfortunate error in the design of the Optimus black prevents you from using the phone as a PHONE. every time you hold the phone in your hand, the network drops. So much so that we went able to get through a decent phone call to test audio quality. At first we thought the device was defective and got a replacement test unit, but alas!, still no proper network. So how good is a phone thats not a phone? its pathetic, is what it is, purely pathetic.

    The touchscreen is a 4 point multitouch which allows for a simply great messaging experience, not to forget the iPhone style keyboard. The network issue prevails here as well, as you grip the phone to type, the device looses network.

    Data & Battery

    The Optimus Black is almost Satan’s child when it comes to how hot it gets on a data connection, its almost impossible to handle. The device gets blazing hot and starts to loose battery at an alarming rate, flat dead in 25-40 minutes. With data off, you get about 4 hours of talk time along with about two days of standby.

    Not having been able to test internet performance we can’t comment on the battery life beyond that.

    Conclusion

    Its a pity that LG let us down yet again, we really liked the device when we got it at first. The device has good specs, excellent build, brilliant cameras and a very – very bright display. A great touch screen and decent hardware, but the device basically fails at being a phone. The death grip network loss issue is beyond excuse and cannot be mended with any kind of fix. ( except a full silicon cover or gloves on the users hands) the phone also performed poorly in the benchmarks.

    We had a lot of expectations from this device and feel totally let down. LG really needs to step up their game, they have possibly good hardware, but something somewhere went wrong with the Optimus Black.

    Tech 101 – How Touch Screens Work

    Previously, we’ve explained How Liquid Crystal Displays Work as well as How OLED Displays Work. Today, we’re going to explain how Touch Screens Work.

    Touch Screens are all the rage today. You’ll find them in many devices like tablets, smart-phones, computer monitors, PDAs, ATMs, table tops, kiosks etc. A touch screen can use multiple inputs from your fingers to styluses and even sausages! But how does this marvel of technology really work? There are many different types of touch screen displays. You will hear many marketing gimmicks regarding capacitive or resistive technology, but most people just don’t know the difference. Read on to learn more about this fascinating technology.

     The first touch screen was made all the way back in 1965 by E.A. Johnson at the Royal Radar Establishment, Malvern, UK. Since that first prototype, many methods of detecting touch on a display have been developed. The most widely used touch screen technologies are explained below:

    Resistive Touch Screens

    A resistive touch screen is composed of many layers. The two most important layers are made of a flexible polymer which are coated with a resistive material and are separated with an air gap or microdots. The resistive material is applied in lines on each sheet and they are placed perpendicular to each other. When a person touches their finger to a resistive touch screen, the two layers are pressed together, and the points of intersection on the two layers allow the processor to accurately measure the position of the touch.

    When pressure is applied to the screen, a uniform voltage is applied to the first sheet, and the second sheet measures the voltage as distance along the first sheet, which gives the X coordinate. Similarly, when the X coordinate has been ascertained, a voltage is applied to the second sheet, and the first sheet is used to measure the distance, which gives the Y coordinate. These measurements take place in only a few milliseconds, which means that a touch is registered as soon as contact is made.

    Since these types of touch screens rely on a point of contact between the two resistive layers, any pointing device like a finger or stylus can be used on them. These screens are also quite inexpensive to manufacture as they don’t require any specialized components. Due to the design of these screens, registering multiple points of contact was not possible due to vectoring issues. However, new technology is now available that overcomes these vectoring issues and allows multiple points of contact to be measured.

     

    Capacitive Touch Screens

    Capacitive touch screens can be based on two different technologies:

    Surface Capacitance

    This is the most basic form of capacitive touch screen technology. One side of the insulator is coated with a conductive layer. A voltage is applied to this conductive layer, which results in a uniform electrostatic field. When you bring your finger in contact with the screen, a capacitor is formed dynamically. This changes the electrostatic field across the screen and this change is measured by sensors placed in the four corners of the screen. The point of contact can be accurately measured based on the change in capacitance in the four corners of the screen. The greater the change in any corner, the closer the point of touch is to that corner. As there are no moving parts, these types of capacitive touch screens are very durable and are used in industrial applications as well as kiosks.

     

    Projected Capacitance

    Projected capacitive touch screens work on a principle similar to the matrix found in Liquid Crystal Displays. There can be either a single layer on which an X-Y grid is etched to form a grid pattern of electrodes or two separate perpendicular layers on which parallel lines are etched to form the grid. There are two basic types of projected capacitance technologies – Mutual capacitance and self capacitance.

    • Mutual Capacitance: These types of capacitive displays have a capacitor at every intersection along the grid. A voltage is applied across the rows or columns which creates a local electric field across the display. When it is touched with a finger or capacitive stylus, the capacitance at each point on the grid changes, which can be measured and gives an accurate location of the point o contact. This technology can measure multiple points of touch.
    • Self Capacitance: This type of capacitive touch screen can have the same grid pattern as a Mutual Capacitance screen but the rows and columns operate independently. With this type of screen, the capacitive load of a finger is measured on each row and column by a current meter which gives the point of touch. These types of screens can only measure one point of touch at a time.

    Projected Capacitance touch screens can operate without direct contact and can have a layer of insulation between the user and the screen itself. However, they require the use of a capacitive input device in the form of a human finger or a specialized stylus with a capacitive foam tip. These types of touchscreens are more expensive to manufacture than resistive touch screens. They also face issues when in contact with any capacitive material like water.

     

    Infrared Touch Screens

    These types of touch screens work on a very simple principle. Infrared LEDs or lasers are used to form an X-Y grid on the surface of the screen. These transmitters are coupled with receivers that monitor the grid pattern. When a touch event occurs, the infrared light from the transmitters is blocked in that region. The receivers that are no longer detecting an infrared signal are used to measure the exact point of contact.

    Infrared touch screens face many problems from objects that obstruct the infrared grid such as smudges on the screen and dust particles. Any kind of input can be taken on these screen from fingers to gloves to styluses.

     

    So now that you know how a touch screen works, we hope that you can have a new-found appreciation for all the devices that use this technology. A tremendous amount of research and hard work has been put in to make an input interface for a sense that most of us take for granted – Touch.
