NOKIA 6760 SLIDE REVIEW
The Nokia 6760 slide is a device optimized for messaging with a full keyboard and support for WCDMA 900/2100 HSDPA and EGSM 850/900/1800/1900. Find directions and locations with the integrated A-GPS and included Ovi Maps. Take photos with a 3.2 megapixel camera and enjoy videos, music and graphics on the 2.4” QVGA (320 x 240) pixels), 16M color display. Additional features include Bluetooth 2.0 +EDR with Bluetooth Stereo and USB 2.0.
The 6760 slide will be available during the third quarter of 2009 for €199 (HARGA) before subsidies and taxes.

The sliding mechanism is one of the major issues that plague the Nokia 6760 slide, because it does feel cheap and wobbly. Moreover, the all-round workmanship is average. All materials the phone is made of are pleasing to touch, but the handset itself doesn’t come in solid and reliable, something not typical the manufacturer.The top side of the Nokia 6760 slide hosts 2.5mm jack and charger port, while the microUSB connector is on the left. The phone comes boxed with the respective accessories – headset, charger, USB cable, user guide and 2GB microSD card that should be inserted into the slot under the back panel.

NOKIA 6730 CLASSIC
REVIEW AND SPECIFICATIONS
The Nokia 6730 classic is a quad-band GSM mid-level phone with 3G support and will be an exclusive for Vodafone. It runs on Symbian S60 3rd Edition, has an integrated A-GPS and a 3.2-megapixel camera that can capture VGA videos.

Nokia’s first name starts with the number 6 is a serious product for the primary purpose of the business office. But not so for the 6730 Classic. This product brings all the features into it with a measure that can be practically equivalent. Includes multimedia features that are not home raised. There are 3.2 megapixel camera. Although still use CMOS sensor, this camera is equipped with the latest features. Including flashing lights and a number of professional camera settings. Without the presence of auto focus. The result can be seen in the picture below. Not bad, almost any angle can be captured with the focus. It’s just for indoor photos, the result depends on the amount of light falling on the object. Because if you rely on the flash, the result is not so good. To record a video, this camera has a performance under the products N-series Nokia. The reason is able to record video in MP4 format has only a maximum framerate of 15 fps (frames per second) although the resolution is VGA.

In addition to our camera can get a special music player Nokia and Real Player as a typical S60 phone. Both players multimedia files are working together to play different formats, including: mp4, 3gp, RealVideo 8/9/10, mp3, wma, aac, eAAC, eAAC +, MIDI, WAV.

6730 Classic is equipped with means of connection is fairly complete. To browse the internet for example, this phone has a modem with HSDPA. This means that existing high-speed data lines up to 10.2 Mbps (download) and 2 Mbps (upload). This means that existing real-speed data lines it will depend on the availability of operator services. Where until now still in about 3.2 mbps.

Congenital browser related, it had nothing to complain about. It’s just because the screen size is not big enough, for some people, do browse through this phone will feel uncomfortable.

While other means of connection are available, including a Bluetooth that supports A2DP and data cable. There is no WiFi connection on this phone, naturally, in accordance with the price.

Feature that is not less important that 6730 classic is owned by GPS. Not only have the internal receiver, but the navigation feature “turn by turn” we can use. Although only differ in the licensing policy, the Nokia maps and navigation features in this 6730 is better than the navigation feature trial version for 6 months which was held mobile phones Nokia new.

This feature can lead us towards the destination location map view 2-dimensional or 3 dimensional, complete with voice navigator in ‘real time’. There is no guiding voice delay when tried in Tangerang-Jakarta trip. Voice Navigator comes right at the point where we must turn so that we no longer see the digital map on the phone.

In accordance with the recent mobile trends, and in line with the data path has been prepared, a number of online features can be found here. There are search facilities are reinforced by a Google search, email either mail or e-mail Ovi other semi push, music search, music store, and so on.

In addition, we also buy, install and play N-Gage games in the 6730 classic. Even with Java MIDP 2.0 technology that has a powerful virtual machine, then almost all java applications and games can be installed and played well. But remember, adjust the screen resolution. Beyond the capabilities of this OS is capable of executing a number of applications Symbian S60 3rd Edition.

Nokia 5030 XpressRadio REVIEW AND SPECIFICATION
The Nokia 5030 XpressRadio allows you to tune into radio instead of playing tracks, that is why it’s priced much cheaper than the former two models. It comes in the form of a candy bar, priced (HARGA) at EUR40 only before subsidies and taxes and will go on sale in this summer. The 5030 XpressRadio should also come with a loud speaker, which eliminates the need of headphones while listening to your radio.
Nokia 5030 is the company's first phone with an internal FM radio antenna, which eliminates the need for a headset or external speakers. The one touch FM radio and channel selection keys on the side of the Nokia 5030 cell phone ensure the product lives up to its XpressRadio name. Placed sideways on the table, the Nokia 5030 phone doubles as a portable FM radio and is ideal for emerging markets, where people rely on a radio as their main source of entertainment and news. The Nokia 5030 ExpressRadio has up to a day of listening time and 10 hours of talk time, which comes to life with the powerful loudspeaker, and is available in 2 colors: graphite & red.

The Nokia 5030 Xpress Radio has a superb listening time capacity and functions towards providing up to 10 hours of talktime. It is available with the powerful loud speaker and available in two eye catching colors namely; graphite and red.

The phone epitomizes simplicity and still functions towards providing the best of features to the consumer. It is equipped by a 1.8” 128 x 160 pixel TFT display, 2.5mm audio socket, a flashlight, a built in loud speaker and mp3 grade ringtones.

Weighing only 82 grams, the phone provides all that’s required by a consumer when it comes to mobile communication requirements.

The 1.8” TFT screen tends to display awesome 65,000 colors.

Last but not the least, Nokia 5030 Xpress Radio is a perfect way to enjoy music as well as avail the best of mobile communication features.

Nokia 3710 fold REVIEW AND SPESIFIKASI
A little tip to Nokia: don’t bother announcing stuff like this at the exact same time as monsters like the E72, because we assure you that no one’s going to care. That’s a shame, too, because Nokia 3710 fold is a surprisingly well-equipped phone for the €140 Nokia will be asking for it (about $193) unlocked when it launches in the fourth quarter of the year — on top of the standard Series 40, AGPS, stereo Bluetooth, FM radio, and concealed external display, you’ve also got a full 3.2 megapixels of photographic power and 3G.The Nokia 3710 fold is a flip form factor cheap mobile phone that gives best of feature and style. The Nokia 3710 fold supports GSM 850 / 900 / 1800 / 1900 on 2G network and UMTS 850 / 1900 / 2100 on 3G network. The 3710 fold is based on Series 40 backbone and comes with support for Ovi Store. The basic aim of Nokia is to provide mobile internet experience to the newly growing. The Nokia 3710 fold is equipped with a 2.2 inch screen that is 320 pixels tall, 240 pixels wide, and displays 16.7 million colors, and this handset also has a second display on the front measures 1.36 inches across, is black and white, and has a resolution of 160 x 128. This cell phone is equipped with a 3.2 mega pixel camera with auto focus and LED flash and has a microSD card slot option which can be extended up to 8 GB. Nokia Maps are pre-installed in Nokia3710 fold and an internal GPS will let you use turn-by-turn or pedestrian navigation features.

Rangkaian Power Amplifier 2000 Watt

Power amplifier circuit provides berukut Capable up to 2000W peak power and a minimum of 1500W continuous, it has to be said that this amplifier will blow up any speaker connected to it. Regardless of the claimed power that can handle various drivers, they can not. To put this whole issue into perspective, take the most powerful and robust drivers you can (8 ohms), and connect it directly to the 110V mains (I recommend this as a 'thought experiment', rather than actually doing it!). 110V RMS into 8 ohms is 1500 W. How long would you expect the speaker to last? Most will be toast within perhaps 30 seconds or less! A very few will last slightly longer, but none will take that level of abuse for more than a few minutes.
Skema Rangkaian Power Amplifier 2000 Watt

Note:

It is imperative that Q5 (the bias servo transistor) is mounted on the heatsink, in excellent thermal contact. This is because, unlike most of my other designs, this amp uses conventional Darlington output configuration. It is necessary to use a Darlington arrangement (or a low power Darlington transistor as shown) for Q5 to ensure that the bias remains at a safe value with temperature. There is probably good cause to model and test this aspect of the design very carefully, because it is so important. The arrangement as shown will reduce quiescent current at elevated temperatures. For example, if total Iq at 24°C is 165mA, this will fall to ~40mA at 70°C. This is probably fine, because there is some delay between the a power 'surge' and the output transistors transferring their heat to the bias servo via the heatsink.

The circuit is completely conventional, using a long tailed pair input stage, direct coupled to the VAS. No current mirror was used for the LTP, as this increases open loop gain and may give rise to stability issues. In a very high power amp, stability is paramount. The amp must never oscillate under any normal load condition, because the heat created can cause almost instant transistor failure.

The power supply needed for an amp of this size is massive. Grown welding machines will look at it and cry. For intermittent operation, you need a minimum of a 1000VA transformer (or 1500VA for the 2000W version), and it will have to be custom made because of the voltages used. If you expect to run the amp at continuous high power, then transformers should be 2kVA and 3000VA respectively. Filter capacitors will pose a problem - because you need caps rated for 150V, these will be hard to find. Because high voltage high value caps can be difficult to find, it may be necessary to use two electros in series for each capacitor location. This is the arrangement shown. You must include the resistors in parallel - these equalise the voltage across each capacitor so that they have the same voltage. Remember to verify the ripple current rating! This can be expected to be over 10A, and under-rated capacitors will blow up.



Another difficulty is the bridge rectifier. Although 35A bridges would seem to be adequate, the peak repetitive current is so high that they may not be up to the task. I suggest that you use two (or even three) in parallel as shown. The bridge rectifier voltage rating should be a minimum of 400V, and they must be mounted on a substantial heatsink.

WARNING

This project describes an amplifier, power supply and tests procedures that are all inherently dangerous. Nothing described in this article should even be considered unless you are fully experienced, know exactly what you are doing, and are willing to take full 100% responsibility for what you do. There are aspects of the design that may require analysis, fault-finding and/or modification

NOKIA E72
NOKIA E72 REVIEW AND SPECIFICATION
The all new Nokia E72 boasts a host of new features including optical scrolling and a five-megapixel camera. Building on the success of the E71, the E72 takes the very best of Nokia’s most successful QWERTY device and makes it even better. The super-slim 10mm frame has been refined with some sleek design touches and inside the device is treated to a range of user interface improvements too.

The optical navigation key makes scrolling through emails a breeze and also helps bounce around the menus quickly and easily. The camera has been upgraded to a full five megapixels and heavy data users will love the support for up to 10.2Mbps connections over HSDPA. The audio jack has also had the upgrade treatment with 3.5mm jack now appearing on the top of the device.

Nokia Messaging is also on board (with a lifetime license) and now supports access and easy set up for Instant Messaging accounts including Yahoo! Messenger, Google Talk and Ovi, amongst others. Email set up is even easier than before through Nokia Messaging, Mail for Exchange and IBM Lotus Notes Traveler.

“The research shows that people are spending an average of five full days per year - equivalent to a full work week - responding to emails. Half of us (46 percent) choose email over voice or text to send and receive important information. The Nokia E72 was designed exactly with this kind of person in mind - it allows the owner to be more responsive and communicate how they want, whenever they want and wherever they are,” Nokia Vice President Ukko Lappalainen commented on the research.

Nokia 5530 XpressMusicGAMBAR NOKIA 5530 XpressMusic
Nokia 5530 XpressMusic
NOKIA 5530 XpressMusic REVIEW AND SPECIFICATION
As far as we're concerned, Nokia's 5530 XpressMusic far and away out-classes its more expensive older brother the 5800, even if it is lacking in the 3G department. British phone retailer mobiles.co.uk thought it best to tease us with an unboxing video of their own, along with some quick impressions of the touchscreen device. It's certainly a looker, and a sleek device they're pretty confident will do well. Some of the S60 5th edition additions are very welcomed, such as the new scrolling contacts bar, but for better and for worse (mostly worse), it's still S60. See it for yourself after the break, and if you wish really hard, there's a good chance this still won't get 3G, but at least you can say you tried.

It's a phone not too dissimilar to the 5800 XpressMusic in shape, albeit slightly smaller with a 2.9-inch screen. It feels lightweight and the screen is noticeably smaller than other touchscreen offerings, but it doesn't feel too tiny for a touchscreen, although it's probably on the edge of what's acceptable.

It should be pointed out that this is Nokia's budget offering, coming in at a price of £129.99 from the Carphone Warehouse, and therefore some compromises will have been made to shrink the cost of the phone down while maintaining a lot of the feel of its bigger brother, the 5800 XpressMusic.
The top houses the on/off switch, which is quite small and seems a little lonely all alone on the face - but perhaps it's being punished by Nokia for some misdemeanour on a lowly S40 device, as it's usually accompanied by a USB socket and/or a 3.5 mm jack.

The front of the Nokia 5530 XpressMusic also holds a number of touch sensitive keys, namely call and terminate options, a menu button and a media button located at the top which calls up elements of the phone like pictures, video and music on a drop-down menu. This touch sensitive element requires a bit of a poke to get working, but that's still miles better than the 'breathe and you'll hit it' touch sensitive buttons on the LG GD900 Crystal.

Nokia has also deigned to give us a 3.2MP camera with single LED flash on the rear of the 5530 XpressMusic, although this is a basic mobile photography effort with no sign of the Carl Zeiss that adorn the N-series handset cameras.The front also has a stainless steel finish (although you have to peer closely to realise it) and houses two speakers for stereo output, which work quite well and will be looked at in more detail in the media section
