Here will introduce a palm size cell phone jammers

The manufacture process and technology of cell phone jammers will be renewed and revised.
To pay a certain amount of calls per month, pay the full two years can have this phone and given 14 days probation period, if you are not satisfied, you can cancel the agreement, returned to the mobile phone network operators. This is our country, "China Mobile and China Unicom launched prepaid calls to send the phone is somewhat similar, the difference is more humane, the foreign service, you can have the 14-day trial period, if you use unhappy, and free exchange within 14 days of the other models, this machine without the network or not, you have the final say. All there is this machine 14 days. The machine fineness of good items fineness of 99 to 100%, all original accessories. The working instruction of cell phone jammers should be renewed too.
14 secret in a foreign country, tried, strictly speaking, not a new machine, it should be said to be filling the new machine; appearance is difficult to identify due to foreign network operators require the phone to fourteen days trial period can not be damaged, it will be net of depreciation expense, so a lot of fourteen days the machine appearance is unable to identify whether the new machine; concrete from several aspects: 1, the packaging is worn; a close look at the phone The charging port and battery with or without scratches headphones and related accessories to be opened too; 3, enter the mobile phone interface to see whether the call records and contacts with or without record. It is the three-antenna wireless signal cell phone jammers .Here will introduce a palm size cell phone jammers
Purchase Note: the 14 secret 14 secret and a new machine purchase price difference of $ 100-200, do not rule out some distribution will take the 14 secret when a new machine for sale, at the time of purchase must be carefully view; not all phones 14 secret, and generally there are 14 secret specific models are as follows: Nokia N-GAGE, Dopod 686, the XDA, the SIEMENS SX65, Dopod 515 (SPV) Sony Ericsson T610, Panasonic GD87, NEC, C616, C313, Motorola A835, a920 models . Trigger is also the last one to two years to appear. The so-called trigger is assembled machine. Outflow from the mobile phone production factory accessories by skilled workers, self-assembly sales. Here will introduce a new type of three antenna wireless signal cell phone jammers .
For example, the past two years the fire of the Sony Ericsson T618, factories located in Beijing, workers tried a variety of ways to take the accessories directly from the pipeline, and then brought back home, assembled, sold to wholesalers. This phone a lot of accessories do not go through quality inspection, so the quality is uneven, and definitely do not recommend the purchase. On one of the phones the difference between parallel and mainstream. First affirmed either parallel or licensed, are regular manufacturers. Parallel does not mean that products mixed with water made a false parallel as counterfeit, counterfeiting, the degree of integration of mobile phone technology is not yet behind to make people imitation, unless it is a OEM product, for example, Kejian and Samsung. Lenovo and LG, Capitel, and Nokia, and so on.  cell phone jammers is recently well received by the customer in the domestic market and oversea market.

The main body of cell phone jammer should be installed on the top

 Personality, social factors and individual background variables on the mobile phone text messages have a certain psychological predictors. Personality, social factors and individual psychological background variables through SMS mobile phone text messages as an intermediary variables on the use of the Indirect impact. While the extraversion personality and sense of responsibility can also be used directly to predict behavior of mobile phone text messages.  Study were 475 valid questionnaires, which have cell phones, the number of people using SMS 81.5%. And consistent with previous findings, gender, whether to use SMS, SMS cost ratio and the number of SMS sent in did not show significant differences in the impact of family origin is an important factor in the use of SMS. To the individual background variables, social factors and Big Five personality as a predictor variable, the need to make friends as the dependent variable for multiple regression analysis, the results can be found not found the variable into the regression equation, indicating that these variables can not predict the respondents from the phone SMS in the need to make friends. The personal, social, and psychological factors can not only directly affect the behavior of SMS use, but also indirectly through the psychological impact of mobile phone SMS text messaging usage behavior. The more visualized explanation is that the requestor is serially connected with the power end of cell phone jammer . In addition, the various dimensions of social support through the impact on the understanding of the prevalence of mobile phone text messages, SMS can also affect the adoption, but the indirect effects of several sub-dimensions there are also negative, temporarily unable to identify its overall impact. SMS students and levels of consumption structure is relatively simple, the impact SMS consumption, the main factor is price, followed by the SMS unique expression. Students send SMSs main target is family and friends, mainly for blessings class, the purpose is to increase contact and exchange feelings, access to information. SMS mobile phone costs account for the proportion of expenditure generally below 50%, generally in the week to send the number 50 below. The main body of cell phone jammer should be installed on the top inside the box with the antenna coming out of the box body.
Nokias highly trained staff has been reflected in the market. From the service side, the customer believes that Nokia service personnel trained, professional and standards. However, we believe that Nokias personnel training system although very advanced, but which lack a very important factor, that is humane. The results from the previous market research, we learned that the customer is usually very reliable service with Motorola phones Nokia, but Nokia mobile phone service although professional but not much expression. Instead of Motorola employees in the "smile" of the relative place. Nokia Corporation (Nokia Corporation NYSE: NOK) is a multinational mobile communications products, headquartered in Finland. In the mobile phone market, Nokia has for years occupied the market share position.

Build a PIC Security System Dials Your Cell Phone Circuit Diagram

This is a simple PIC Security System Dials Your Cell Phone Circuit Diagram. Do-it-yourself phone dialer security system calls your cell phone, office etc. whenever a door or window is opened, or panic button is pressed. Great Home Alarm.

PIC Security System Dials Your Cell Phone Circuit Diagram

PIC Security System Dials Your Cell Phone Circuit Diagram


The circuit consists of a small PIC microcontroller, assembly program, and a few other parts to detect a switch closure from an open door, window, or manual push button and then dial the cell phone number, and transmit a steady tone to indicate the source of the call. The circuit uses the pulse dialing system to interrupt the line connection a number of times to indicate each digit. Pulse dialing (the oldest form of dialing) works by actually disconnecting or "hanging up" the phone line a number of times to indicate each digit. For example, the digit "5" would be dialed by disconnecting and reconnecting the line 5 times in short intervals of about 100mS. There is about a 1 second pause (with the line connected) between each digit. The timing is not critical and I was able to dial 411 and connect to the local information service just using a momentary push button switch in series with the phone line.

Circuit Operation:
In operation, the switch closure is detected on pin 7 of the processor which activates the reed relay and takes the line off-hook for 3 seconds to establish the dial tone. The processor then dials the number by opening and closing the relay a number of times for each digit. When dialing is complete, the processor waits 3 seconds and then transmits a steady tone of about 300Hz for 30 seconds through the modem transformer. The call is then terminated and the processor waits for the switch to open before resetting.

Design Considerations:

The PIC16F628 (18 pin) processor was selected because I had a few on hand and my homemade hardware programmer only accepts 18 pin devices. A smaller 8 pin device could have been used since only three I/O lines are needed, but the difference in cost is only about $1.50. One of the I/O lines (RA5) is used for programming and is always an input, but can used as a functional input so the switch closure could be detected on this line thus eliminating the need for one pullup resistor. But I elected to use 3 consecutive I/O pins (7,8,9) of the 8 bit port B and leave RA5 pulled up with a extra 10K resistor.

The output pins (8,9) that drive the relay and transformer are limited to 25mA of current each, so an extra transistor (2N2222A) was needed to supply additional current to the relay coil. The transformer resistance is around 100 ohms, so an additional 330 ohm resistor was added in series with pin 9 to limit the transformer current to around 10mA. An LED indicator and 330 ohm resistor were used on pin 8 to observe the dialing activity and indicate the line status. Several of the parts (relay, transformer and blocking capacitor) were obtained from an old 56K modem card.

The schematic shows a 47uF / 50 volt non-polarized capacitor used to block DC current to the transformer, however a regular polarized 50uF cap could be used if correct phone line polarity is observed. The modem was probably designed to work with unknown polarities at different locations, so a non-polarized cap was used. Its possible the cap and 470 ohm resistor can be replaced with a single resistor in series with the line to set the "off hook" line current to around 20mA. This may cause partial saturation of the transformer and reduced audio level, but might work well enough.

The power supply voltage is not critical and a 4.5 volt supply from three AA batteries should work. Or a switching type regulated 5 volt wall transformer can be used. The problem is insuring the relay gets enough voltage to operate. The rest of the circuit should run on reduced voltage. I used a 4.2 volt cell phone charger that worked well.

The antenna impedance of Cell Phone Jammers can be conveniently calculated

The antenna impedance of Cell Phone Jammers can be conveniently calculated.
Although the RAZR fame, but a series of "hardcore" products continue to cut prices, but also to the current Motorola products, profit margin is only 11.2%, while rivals such as Nokia was 16.8%. As the cell phone sales continued to decline, Motorola on January 31, 2008 announced that it will consider selling cell phone unit. Was a summary of Motorola, "as also V3, loser V3", this sentence is probably the best summary. Motorola, a decline of the nobility, witnessed the cell phone from 1G to 2G era of history. 2G era, there are many companies that can be introduced, such as Nokia, we later re-described. Following the first 3G-related things to talk about. Speaking of 3G, had referred to a company --- Qualcomm. Many people say that Qualcomm is a rogue company, how a rogue law? The customer is interested in the jamming power range of Cell Phone Jammers .
Qualcomm, founded in July 1985. ? founder and chairman of Irwin Jacobs, the father was undertook CDMA. Qualcomms finest creations, Korea CDMA commercial operation is successful. However, Qualcomms royalties more outrageous expensive, according to South Korean Ministry of Information and Communication issued a report, using Qualcomms CDMA technology cell phone manufacturers in Korea during the period 1995-2005 a total of $ 2.6 billion to pay royalties . Reported that in 2004, including Samsung Electronics and LG Electronics of South Korean cell phone makers, including royalty payments totaling up to about $ 565.7 million, approximately $ 514 million in 2005. In China, 3G also mentioned this thing for several years, from 05 onwards, every year the media say, "3G licenses this year put the card", but was delayed until 2009, why still have not realized? The customer asks for the antenna impedance of Cell Phone Jammers .
The shadow which is inseparable from Qualcomm, because all the patents related to 3G technology, Qualcomm is an absolutely dominant position in CDMA2000, with the major basic patents, and patents account for 29% of the share. Qualcomm also holds 6% of WCDMA patents. Qualcomm has always adhere to high patent fees, negotiations stalled repeatedly, and many called it as rogue companies. Some people have to ask, 3G What are the advantages ah? In fact, is a major advantage: the Internet speed. We all know that the GPRS Internet access, speed is very slow, with the cell phone QQ also similar to browsing the Web becomes larger point is slow, and slower than downloading MP3 songs, download movies, even to die. The 3G cell phone not only can easily download music, but also smooth viewing television, movies, and make video calls. Among them, the board of the motherboard battery These prices are more transparent, housing a number of relatively large difference, I have seen more expensive imitation of NOKIA 8900 high purity steel shell, to be $ 250. Many kinds of motherboards, the MTK program, the current market appear more have 6223 platform and 6225 platforms. One 6223 platform does not support USB function, one of the 6223C of the CPU, camera supports up to 100,000 pixels, is common in low-end small-screen cell phone, 6225 to support 300,000 pixels, USB port expenses, in many of the big screen cell phone use it.

Car Mobile Phone Charger Circuit

Car Mobile Phone Charger Circuit
Cellphone battery charging process when were done traveling is a big problem. Because when traveling source of power supply is generally difficult to find. If you turn on your phone then the battery continuously over time will run out within a period of five to six hours and eventually mobile phones unusable. Here is described a series of simple charger that will increase battery life two to three hours.


In principle, the charger uses a series of Limited Voltage Current Source. Generally requires cellphone battery voltage 3.6 - 6 volts DC and currents 180-200 mA to perform the charging process. Cellphone battery usually consists of three NiCd battery cells, and each cell has a voltage of 1.2 volts potential. At the speed - average low flows required to charge mobile phone battery about - about 100mA.

Car Mobile Phone Charger Circuit schematics

In this series there is a 12V voltage source consists of 8 regular battery cells (each cell 1.5 Volt) able to supply current at 1.8 A which is connected with output terminals.

The circuit is also able to monitor the battery voltage level which is in charge. And will automatically cut off the charging process when the output terminal detects a certain battery voltage level predetermined. Timer IC NE555 is used to charge and monitor the voltage level in the battery, Pin 5 (IC1) as the control voltage using a reference voltage zener voltage 5.6Volt. Voltage at Pin 6 as the threshold set by VR1 and the voltage at Pin 2 as the trigger is set by VR2.

When the cellphone battery is connected in series (the Charging Process) applied voltage on PIN2 (IC1) as a trigger would be below the value 1 / 3 Vcc and will cause the Flip-Flop in IC1 will ON and on Pin 3 (IC1) will be high (Cause transistor T1 saturation.). When the battery is full (Full Charge) then the voltage will rise and the voltage on the PIN2 (IC1) will be above the level of trigger point threshold. This will cause the Flip Flop OFF and the output will be low (transistor T1 causes the cutoff) and indirectly also the charging process will stop.

Pin 6 (Threshold IC1) is set at 2 / 3 Vcc by using VR1, transistors T1 which is used to increase the charging current. R3 value is very important to provide the charging current, by setting the value of R3 to 39 ohms then the charging current supplied approximately 180mA. This circuit can be built on any type of PCB (General Purpose PCB) for the calibration process using the DC voltage level cutoff Variable Power Supply. Connect the output terminal circuit with Variable DC Power Supply and set on 7 volts. Adjust VR1 in middle position and slowly adjust VR2 until LED1 OFF, this indicates Low Output. LED1 should turn on when the DC Variable Power Supply voltage is reduced below 5V. LED1 Status flame shown in the table below. Closed circuit with plastic casing and use a suitable connector for connecting to the Battery for Mobile.

Make A Virtual Phone Battery

Virtual cell phone battery is a replacement cell phone batteries for those of you who use the phone as a modem. Including myself, who use the phone as a modem HAIER d1200p internet.  Why must use this virtual battery. For those who surf hobby "full time" with a phone modem, would know the problem, the battery gets hot and fast reply wasteful even worn out.
virtual phone battery circuit
This tool is a good solution to keep and care for our cell phones from the possibility of damage from over-charging its battery.I created a virtual battery works as follows:We take the source of its power supply from the USB port because the port is very easy and simple to use and simply provide a standard current source when the phone is online (500-750mA).

The workings of the circuit is as follows:Diodes or diode 2Amper in 5239 this standard to provide a useful addition to the polarity of the voltage which is also a component of protection against misuse. You can just use a 1 Amp diode (IN4002-4007). I use the IN 5239 is due to be durable, more resistant to heat.4v3 zener diode IN4007 and configured to create a portal voltage of 5V (4.3 + 0.7 volt zener Vin4007) and is useful as a protection system against possible voltage spikes in the event of damage to the CPU.220nF capacitor as a stabilizer and a substitute for the original battery cells.

The following also 100pF capacitor to smooth and filter the dc current through the diode 5239 which came out of the induction logging.Configuration between zener4v3, IN4007 diode and C 220n form a cell replacement from the actual battery cells, because the battery was actually a capacitor which had a large capacity.You can just remove the three components mentioned above. although it can work fine .

But results are not as good as that use virtual cell (replacement), which certainly was the security which we have to think to avoid the things which are not in want.Making way is to use an old cell phone batteries which have been wasting his cell, a raft of this circuit and the solder terminals on the batteries with the polarity distinguished. Make two holes for the cable to the jack / USB jack.

 Determine the length of cable required to taste and use stranded cable with a diameter of at least 1mm.If some type of cell phone batteries are very thin, use a small box for this circuit and connect the two wires to the output voltage again for hp battery casing. Or also if you do not have a former battery casing, use alligator clips to the battery terminal on the phone .. Pin the middle of the virtual pin replacement battery is BSI (Battery Size Insdicator) is useful for HP Nokia.
