Apple iPad REVIEW
Apple released the Apple iPad, such as the time mentioned in the posting about the Apple iPhone 4G some time ago it was true promise of the sweet Apple will release this before the iPhone 4G released. As we all know Apple Tablet rumors have been rolling for a long time and in fact the fair has become a rumor last nearly 10 years. Steve Jobs came up on stage in the Apple Event in San Francisco and announced to the audience that their new device will be called the iPad. The gadget has only a half-inch thickness has a weight of 0.6 kilograms. 9.7-inch display with touch screen, Apple's latest pledge is powered microchip A4 1GHz Apple-Designed custom, high-performance, low-power system-on-a-chip. Apple iPad will have the same operating system with the iPhone and have access to 140 000 applications.
First let us look more closely to the price of this Apple iPad. For the 16GB version will bibandrol worth $ 499, which will bibandrol $ 599 32GB and 64GB version will be priced $ 699. All these models come with Wi-Fi, 3G will be added to add tariffs worth $ 130 for each model. Wi-Fi standard model will start off in 60 days, with the 3G version will come in the next 90 days.

Sony Ericsson J105 Naite in REVIEW and SPECIFICATIONS
Sony Ericsson J105 Naite Review
Sony Ericsson J105 Naite Mobile Phone arrives in attractive shades of vapour silver and ginger red. The unit was announced in 2009, May. The unit, no doubt will bowl over consumers world wide!
TFT Display supports 256K colours. Screen size of the excellent unit is 2.2 inches. You can change the wall papers and screen savers to your choice. Vibration, Downloadable polyphonic, MP3, AAC ring tones and composer are the sound alarms to alert you. Speakerphone adds to your convenience. Phone book memory of the competent unit can save up to. 30 received, dialled and missed calls records too are kept by the unit. Picture ID and Ring ID allows you to identify the caller before you pick up the phone. 100 MB Internal and micro SD (Trans Flash) up to 8GB, 2 GB are included.
One of these handsets is the Naite J105 - a relatively cheap candybar phone that sits at the bottom of the Greenheart range. It's available for as little as £60 on Pay As You Go and for free on even the cheapest contracts. Its green credentials are derived from the use of recycled plastics, water-based paints, an energy efficient display, an on-phone manual instead of a paper one, and a lower-power consumption charger (though as the phone tells you every time you unplug it, you should unplug or switch off the charger at the mains anyway to save power). All told these measures apparently result in a 15 per cent drop in the overall CO2 emissions of the phone. This is of course good to hear, though we can't help but feel a 15 per cent saving would easily be bettered simply by buying second-hand and prolonging the life of existing products. Still, if you're looking to buy a new phone, it's good to know you're doing your bit for the environment.
Being a budget phone, it's no surprise that the Naite is lacking somewhat when it comes to fit and finish. That plastic body is rather flimsy and the keypad buttons are very wobbly and overall it just doesn't feel all that solid. It's certainly not going to fall apart at the drop of a hat but it doesn't fill you with confidence. Weighing just 82g, the plastic construction does at least get you a light device and its dimensions of 108 x 47 x 13mm make it highly pocketable as well. We also rather like the simple styling with its matt black back and combination of glossy black and silver on the front.
Also, despite their wobbliness, the buttons of the keypad are relatively easy to use thanks to a neat and logical layout. The action isn't great thanks to that aforementioned wobble but there's still a discernible click so it's easy to tell when you've pressed one. In addition, the navigation buttons are a little small but again not enough to be of major concern. Overall, we found we could type at a decent pace and navigating the menus was not hampered at all by the keys.

SPESIFIKASI HARGA SONY ERICSSON Xperia X2 
SONY ERICSSON XPERIA X2 REVIEW
the SONY ERICSSON XPERIA X2. It´s the first Windows phone of the company, meaning it runs Windows Mobile 6.5. The panel interface we know from the X1 haunts us again, but it has been revamped and the manufacturer´s personalization pack seems to have taken over the standard Windows interface deeper. The XPERIA X2 sports 8-megapixel camera with touch focus, larger display, new keyboard and navigational keys design, plus a microUSB port. We´ve got a prototype intended for Vodafone, but it´s functional, so we will show you what to expect from the first Windows phone of Sony Ericsson.
The design of the Sony Ericsson XPERIA X2 features small changes and the manufacturer has staked on retaining the characteristic style of the X1 and its high build quality. You will almost immediately notice the lack of the prismatic navigational keys on its face side - they are now flat and smooth and the D-Pad has been transformed into an optical pad. The size of the phone display has grown 0.2 inches and now measures the healthy 3.2”.
We're not convinced about the panels system to be honest – as although it's great in practice, it seems to stress out the 528MHz processor a little bit, like it did to a greater degree on the Xperia X1.
Sony Ericsson assured us that this was only because it's a pre-production unit, and while we've heard such claims before, we'll give them the benefit of the doubt in this case.The Windows Mobile interface is still sporting some of the nasty trademark tiny icons we really hate, such as tiny crosses in the corner of the phone to shut down application windows, which ruins things a little bit, especially when we've played with the HTC HD2 which does a bang up job of hiding it all.
But there are a lot of cool features on the Xperia X2 as well – such as being able to re-order your panels by timeline, so basically changing your home screen depending on what you'll be doing at that time.There's also a cool tiled interface that links through to other applications, and while this might not be the most constructive way at looking for the program you're after it's still nice.
And the keyboard, which has been overhauled for this release, is a lot better too, as it's no longer flush with the surface (which made it very difficult to hit indeed). This keyboard will give a lot more accuracy, we reckon, and that will be another big problem fixed from the X1 to the X2.

This is a 3 stage discrete Microphone amplifier circuit with gain control.The first stage built around Q1 operates in common base configuration. This is unusable in audio stages, but in this case, it allows Q1 to operate at low noise levels and improves overall signal to noise ratio. Q2 and Q3 form a direct coupled amplifier.
As the signal from a dynamic microphone is low typically much less than 10mV, then there is little to be gained by setting the collector voltage voltage of Q1 to half the supply voltage. In power amplifiers, biasing to half the supply voltage allows for maximum voltage swing, and highest overload margin, but where input levels are low, any value in the linear part of the operating characteristics will suffice. Here Q1 operates with a collector voltage of 2.4V and a low collector current of around 200uA. This low collector current ensures low noise performance and also raises the input impedance of the stage to around 400 ohms. This is a good match for any dynamic microphone having an impedance's between 200 and 600 ohms.

SONY ERICSSON X10 Mini Pro REVIEW
The SONY ERICSSON X10 Mini Pro takes many of the original handsets features and technology and shrinks them down into a far smaller handset with a 3.2 inch touch screen as opposed to the large 4.3 inch display of the X10, added to this is a full Qwerty slide out keyboard for those people who like to press physical buttons when entering text rather than the on-screen option.
One big difference between the new X10 Mini Pro and the previous X10 and soon to be launched Sony Ericsson X10 Mini is that the camera has been slightly downgraded from 8.1 mega pixels to 5.0, this also helps to keep the price of this new Android handset low with the initial release price slated at £249.99, compared with the £489.99 asking price of the original X10 model this is a huge discount.
The release date for the SIM Free Sony Ericsson Xperia X10 Mini Pro is now confirmed as May 24th 2010, the Mini version of this handset without the Qwerty keyboard is also rumoured to be launching at around the same time giving consumers a real choice of new, smaller Android phones.
The main display changes slightly from the larger model with the manufacturer using short-cuts in each corner of the screen, they claim that this makes it far easier to select features and applications just using your thumb on the smaller touch screen and these can also be personalised to your favourite programs and functions.

Rangkaian op-Amp mic preamplifier
This Circuit of microphone preamplifier has a high quality and using a single power supply, suitable for dynamic or electret microphones. The op-amps Used Can be any low noise, high performance type, eg LM471, NE5534, TL071, OPA 371 etc.
The design is a non-inverting amplifiers design, the input is applied to the non-inverting input of the op-amp pin 3 Which is in most cases. The input impedance is 23.5k, the overall voltage gain is determined by R2 and R1 and with the values of R2 and R1 on the circuit diagram the voltage gain (for mid band, 1KHz) is approximately 27.2dB.
Op-amp feature high gain bandwidth products, have a fast slewing rate and have extremely low noise. It is difficult to achieve the same performance using discrete components. Finally the overall signal to noise ratio has been calculated, the source was a 1k impedance microphone generating a 1mV pk-pk sine wave. An impressive result of 110dB S/n at 1KHz is achieved. In practice this figure will be lower and determined by the quality of the microphone used.

This amplifier operates in Class AB mode with up to 2 watts of output power, the single 470R preset resistor controls the quiescent current PR1 flowing through the BD139/140 complimentary output transistors. Adjustment here, is a trade-off Between low distortion and low quiescent current. Typically, under quiescent conditions, current is about 15 mA, rising to 150 mA with a 50 mV input signal. The frequency response is shown below and is flat from 20Hz to 100kHz

This amplifier circuit is DC biased so that the emitters of the BD139 and BD140 are at approximately half supply voltage, to allow for a maximum output voltage swing. R9 and R10 provide a degree of temperature stabilization which works as follows. If the output transistors are warm, the emitter currents will increase. This causes a greater voltage drop across R9 and R10 reducing the available bias current. All four transistors are direct coupled which ensures:

GAMBAR|HARGA SONY ERICSSON SATIO
SONY ERICSSON SATIO REVIEW
Sony Ericsson Satio is a smartphone, announced by Sony Ericsson at the Mobile World Congress in Barcelona, Spain on 15 February 2009 as the Idou (pronounced "I do"). It was released on 7 October 2009 in the UK in 3 colour schemes: Black, Silver and Bordeaux (Red).
The focus of the phone is the high quality playback of music and video, as well as photography. The camera is located on the back of the phone, behind a slider and features a xenon flash. On the side of the phone, there is a shutter button, and a button which allows you to switch between still and video modes. Next to this is a rocker switch for zooming in and out. Also on this side is a button for playback of photos or video. The other side of the phone has a sliding lock button and a covered slot for a MicroSD card.
There is a front facing video camera on there too for all that video calling fun everyone has these days, but it's down the sides of the phone where the button frenzy really begins.
On the left-hand side is the slider for unlocking the phone (which is in just about the right place for most hands), the standard Sony Ericsson port for USB connection, charging and headphone connection (boo!). Below that lives the microSD slot, which is covered by a nice hinged flap.
Over on the right side of the phone we get the camera controls, with the zoom buttons doubling as the volume up/down keys, despite having the 'proper' zoom icons on.
Below this is the photograph playback key, allowing quick access to your snaps in both camera mode and standby. There's also a video/camera swap hard key as well, which we're trying to work out if it has another function in other applications. It appears not to.
And below that is the stylishly hewn shutter for the camera. This side of the phone is well put together, laid out in the right manner and given the Satio's penchant for touch operation, a welcome addition

This microphone amplifier circuit is very simple, consisting of two levels. with wide dynamic regions, small noise, and can with a long cable about 50 meters. The battery supply is a good compromise: in this Manner The input circuit is free from mains low frequency hum pick-up and connection to The amplifier is more for simple, of due To The absence of mains cable and power supply. Using a stereo microphone the circuit must be doubled. In this case, two separate level controls are better than a dual-ganged stereo potentiometer. Low current drawing (about 2mA) ensures a long battery life.
For better results use Enclosing the circuit in a metal case is highly recommended. output circuit of this microphone can directly connect to the Aux input of your amplifier through screened cable and suitable connectors.

REVIEW AND SPECIFICATION OF NOKIA X2
NOKIA X2 REVIEW
Nokia’s X series –the X3 and X6 and surely what we can expect upcoming X series handsets that seemingly in time with unofficial Nokia X2. In a report by NokiaPort “the Indonesian equivalent of the FCC has approved the Nokia X2, confirming its existence.” Details like quad-band GSM connectivity and Bluetooth also span on the post. Looking closely at the naming convention, X2 suggest low-end handset and obviously cheap favoring the masses.The official announcement from Nokia to show off X2 is still missing for now, but talking about another X-series handset come the interesting mock-up for Nokia X9, which seems quite believable. If this concept will run true, it will be based on X6 and should come with an AMOLED touchscreen display, 12MP camera with HD video recording, HDMI port, and dedicated Facebook and Twitter keys.
