GSM Cell Phone Jammer Circuit
A admirable diy gsm jammer or cellular adaptable buzz jammer schematic diagram for use alone in GSM1900 with abundance from 1930 MHz to 1990 MHz. The GSM1900 cellular corpuscle buzz arrangement is fabricated use of by USA, Canada and best of the nations in South America.
This cellular buzz jammer isnt applicative for use in Europe, Center East, nor Asia. The GSM jammer ambit could block adaptable adaptable buzz signals which operates on GSM1900 band, additionally articular as DCS.

TV Remote Control Jammer
This schema confuses the infra-red receiver in a TV. It produces a constant signal that interferes with the signal from a remote control and prevents the TV detecting a channel-change or any other command. This allows you to watch your own program without anyone changing the channel !! The schema is adjusted to produce a 38kHz signal. The IR diode is called an Infra-red transmitting Diode or IR emitter diode to distinguish it from a receiving diode, called an IR receiver or IR receiving diode. (A Photo diode is a receiving diode).
There are so many IR emitters that we cannot put a generic number on the schema to represent the type of diode. Some types include: CY85G, LD271, CQY37N (45¢), INF3850, INF3880, INF3940 (30¢). The current through the IR LED is limited to 100mA by the inclusion of the two 1N4148 diodes, as these form a constant-current arrangement when combined with the transistor and 5R6 resistor.
TV Remote Control Jammer
This is really fantastic schema.Because you can fun with this schema.If others operate your TV set or setup you can use this to control them.and you can use this to annoy someone.so enjoy with this....

Build a Cell Phone Jammer Schematic Diagram
This cell phone jammer operates at GSM800 frequency since most mobile phones use it to operate. So the selected VCO is a sweeping oscillator, which is very effective but may be hard to construct for the beginners without nice RF-testing equipment.
As a noise source you can use 45MHz clock oscillator which is driving Local Oscillator port located on a mini-circuit mixer. There is also an impedance matching network for Local Oscillator signal to pass through it. It is used to equate impedances of the clock oscillator and the port of the mixer.
RF input (which is this port of the mixer) connected to the first 800MHz cell phone antenna, and the RF output is sent to the mini-circuit amplifier. This amplifier increases the output power for 15-16dbm. The amplified signal then sent to the second cell phone antenna.
works
All cell phones which use GSM800 have their transmitted and received frequencies always separated by 45MHz. So when the mobile phone tries to call it is blocked by its own signal returning to it! Isn’t that cool? When the phone blabber annoys you – turn your jammer on and that wrongdoer will hear own voice in his or her cell phone.
Oh, by the way, you can also use this mobile signal jammer to block any cell-based tracking systems which use your GPS to track and record your car’s moves. And it is quite possible (though I didn’t actually tested it) to jam IEDs which detonated using cell phones.
The mixer used is designed to work up to 600MHz but in this case it works pretty well.
RF amplifier is doing its job perfectly yet (as it was mentioned in the Jammer Store blog post) draws additional power.Old aluminium box was used as a frame for the jammer and old UHF connectors from Motorola cell phone as input/output.You need to attach RF connectors to the circuit. Nine volt battery and voltage regulator were used to supply all components. The battery was placed inside and separated by the foamed plastic from the other components.The power on/off switch is placed on the top. The input and output antennas (also from old Motorola mobile phone) are screwed onto UHF connectors.Your cell phone jammer is ready. Enjoy!

The component of mobile phone jammer is separate
The component of mobile phone jammer is separate.
In Nokias share of nearly 40% behind, hidden in its mobile phone sales channels infighting. Of the Nokia mobile phone sales channels, the channel model of the mobile phone industry is broadly divided into the national agency system, the provincial agency, the manufacturers supply model, first proposed by Nokia provincial direct control of distribution of Nokia mobile phone sales channels mode. Nokia mobile agents Postel and Telling, and last year the introduction of Synnex Technology International. We can find, continuously reported in the first half of this year, Nokia channels to dissatisfaction with the low gross margin and resentment.
The omnidirectional antenna of mobile phone jammer can be provided at different price.
Nanjing Panda Mobile Communications Equipment Co., Ltd. (abbreviation PMC). This is a mobile phone sales, R & D, production, sales and technical service in one enterprise. The company has set up 20 branches in Jiangsu, Sichuan, northeast, Guangdong, Shanghai, Beijing, formed based in Jiangsu, echoing the north and south, radiation thing, the market, sales, business-linked target sales network to expand its market share and actively to expand overseas. According to the Nanjing Panda 2003, its total mobile phone sales in the first half of 2003 of 1.306 billion yuan, ranked fifth in the domestic mobile phone. However, according to latest data released in early April 2004. This mobile phone jammer system has the anti-damage protection function.
Chinese mobile phone an annual capacity of 2004 exceeded 170 million mark, while the total market capacity is only 69 million units, the middle will have to deduction of no small proportion of the mobile phone market (in Guangzhou and other places, and second, the proportion of a conservative estimate more than 20%). According to the view of modern marketing, product characteristics is a key factor in the impact of marketing decisions. So a study of the mobile marketing channel to start from the phones features and marketing features. Phone as a convenient communication tool, has its own characteristics. First of all, the phones main function is the most basic function of communication. With the development of society, an increasingly wide range of peoples activities, the concept of global village has long been popular. It can prevent the intentional and unintentional damage to mobile phone jammer .
