Full Power Mobile Phone Jammer Circuit Diagram .To day if we are talking about expert Cell phone Jammers we are conversing about this schematic underneath. First off all you should be very very cautious how to use this apparatus. Its completely illegal and so the reason. I post this Circuit is only for educational and testing causes. This type of apparatus is being utilised by security for VIPS, particularly at their limousines to avoid blasting device initiating while the vehicle passes from the goal cell phone-bomb. Off course there are those who use it to make a antic or to make the persons crazy in the rectangle block you are. The power of the jammer is currently sufficient to do your thing, but certainly you can place a 30W linear power amp at the RF output and impede a much wider locality. So, Be pleasant individual with that and recall that there are people who may need desperately to obtain or make a call and one of them could be you! And if you can't oppose of functio...

This post share about Mobile Phone charger circuits, previously you can see other Phone Battery Charger Circuit   or Charger Circuit  . This Charger ciruit use to charging phone battery using IC 7805 for plus voltage regulator or & 7905 for min voltage regulator.  Below is a schematic circuit adapter, power supply , or battery charger (for gadgets, mobile phones , MP4player, smartphone) that is equipped with a 5V voltage stabilizer : Diode Bridge diode bridge, known as a diode bridge is used for the rectifier circuit current ( rectifier ) from AC to DC . to make the diode bridge properly you need to know the type of diode to be used, to suit your needs. example: to make the power supply 12 Volt 3 ​​Ampere diode type 1N5401 is needed, for more detail how to choose the right type of diode to the adapter. Voltage stabilizers are commonly used are the 78XX or 79XX type LM, XX indicates the maximum voltage output is generated. see the example in the circuit schem...

Photo: firstpost.com     It has happened to everyone at some time: Just when you were in the middle of an animated conversation with someone on your cellphone, the battery gave up its ghost and went dead on you. Cursing the phone or even yourself had not helped any, had it? It is precisely with this in mind that various entities have been trying to get the batteries recharge themselves. Read More.....

Transceivers, appliances such as mobile phones that can send and receive messages, have become smaller and smaller over the last few years, but users are about to experience a new meaning in miniaturisation.  Research at The Hong Kong University of Science & Technology (HKUST) has successfully combined a unique system architecture and new circuit design techniques to reduce them in size like never before.  Principal Investigator Dr Howard Luong said the handset of a typical mobile phone today may contain between 150 and 300 separate electrical components. His research group proposed and demonstrated circuit techniques that make it possible to combine many of these components to a single chip and therefore to significantly reduce the size of circuitry (see example in graphic). A US patent has been granted for one of the circuit techniques.    The transformation applies to the CMOS (Complimentary Metal-Oxide Semiconductor) manufacturing process, which can produ...

Citing unnamed supply chain sources, as well as what we’re guessing are some better informed sorts within Samsung, the Korea Times claims that the phone will land in February at the Mobile World Congress. The handset is apparently set to hit retailers shortly after in March – just nine months after the release of its predecessor. In news that’s unlikely to surprise anyone on nodding terms with prevailing trends in smartphone upgrades, Samsung’s new kit will purportedly pack a larger five-inch OLED screen – up from the S3’s 4.8-inches - and international 4G LTE support. An unnamed deepthroat said: “Samsung wants to keep its one-year product schedule and the Galaxy S4 will be the first to match that strategy. “The S4 will see some external changes but retain its popular rectangular shape with rounded corner concept.” News of Samsung’s plans comes as it recently announced that the S3 has now sold some 20 million units, making it the company’s fastest-selling phone ever.
