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...

Circuit Description: Ever Imagined controlling your home appliances using your cell phone. You can find a lot of circuits for this application. But they make use of Telephone. I modified the circuit and redesigned it to make it compatible with normal cell phone headphone. Just connect the your phone headphone jack to the phone and the connections to the circuit as shown in the circuit. The relays are connected using the resistor and transistor. Use ULN2803 to reduce the circuit size and increase the performance. The connections from the output of flip-flops has to be given to the inputs of the buffer and relays has to be connected to the buffer. Normally the tip of the headset is connected to the circuit to the 0.1uF capacitor as shown in the circuit diagram. The ground pin of headphone is connected to the ground of the circuit. Circuit Diagram: Operation: When you press keys in your Phone, the other person will hear some tones with respect to keys pressed. This tones are based on the ...
