GSM CELL PHONE JAMMER CIRCUIT
This is Simple GSM Cell Phone Jammer Circuit Diagram. A “Cell Jammer” is just way of saying “Dirty Transmitter” which happens to transmit within the Cellular Phone Bands. Reality is, the dirtier the better. GSM Cell Phones works on 900/1800 Mhz frequency. GSM-900 and GSM-1800 are used in most of the world.
Circuit Diagram
Working
- The 555 timer [8 pin] IC simply makes a noise. It’s coupled via C4 [electrolytic] to modulate the MRF transistor oscillator. With C1 set at roughly 1/3rd, you will be close to 900 MHz. By sweeping the C1 trimmer capacitor, you can swing the output frequency from 800 MHz to 2 GHz with the transistor and values shown above.
- You could replace the 555 chip with an electret microphone and listen to yourself talk on a scanner, so the unit could easily couple as a UHF Bug.
- Instead of a single Tapped Coil, I’ve used two molded inductors for ease of construction. Values for C1, C2, L1 , L2 are critical for the frequency range.
- You might want to build the unit into a metal box, add an on/off switch in the batteries + line, and maybe even add a LED. Connect an old 800 MHz cell phone antenna to C5.
- Would you believe the whole thing can be built on top of the 555 IC itself when using surface mount components, and the lot will fit onto a nine volt battery clip. Output is reasonably good, although the current drain is a bit high, so a new 9 Volt battery will only run about an hour .
- This circuit works on 10-15 metres of range.

LG Gx2 5 7 inch cell with the same laser technology in LG Camera G3
LG is presenting streak new cell before IFA 2014 Earlier this week the company introduced the LG Stylus G3 to challenge the Samsung Galaxy Note, but apparently thats not all you have prepared and presented the LG Gx2, which can be easily confused with the LG G2x years ago.
The new LG cell Gx2 also wants to enter the territory of the Samsung Galaxy Note to have a 5.7 inch screen, but its specifications are still being average and not high end.
Gx2 LG screen has a resolution HD (720p), a quad-core 1.2GHz processor, 1.5GB of RAM and 8GB of storage.
Additionally, the cell has a ATTERY of 3,200mAh, a rear 8 megapixel camera, 1.3 megapixel front camera and battery 3,200mAh. The rear camera has the same technology found in the LG G3, mainly the laser autofocus.
LG has not announced when it would be released in that country and what would be its price. However, there is the possibility that, for the moment, leave only in Asia, but do not rule out the possibility of reaching other markets in the future.

Make this Cell Phone Jammer Circuit at Home
A “Cell Jammer” is actually technique of pointing out a “Nuisance RF Maker” which just might happen to get distributed within the Cellular Phone Bands. Certainty is, the dirtier the more beneficial.
The 555 timer IC purely renders a noise. It’s hooked via C4 to modulate the MRF transistor oscillator. With C1 fixed at about 1/3rd, you will be in close proximity to nine hundred MHz. By cleaning the C1 trimmer capacitor, you could fluctuate the output frequency from 800 MHz to 2 GHz with the transistor and values presented.
You may substitute the 555 chip with an electret microphone and tune in to by yourself lecture on a scanner, thus the product could very well duo as a UHF Bug.
Rather than one particular Tapped Coil, I’ve used a couple of plastic inductors for simple structure.Values for C1,C2,L1,L2 are fundamental for the frequency range.
You may perhaps build the component into a metallic box, add an on/off control in the dc batteries + track, and possibly bring in a LED. Connect a well used eight hundred MHz cellphone antenna to C5.
Do you believe the whole item could be produced on the top of the 555 IC itself when utilizing surface mount parts, and the lot will probably hold onto a 9 volt battery snap. Output is moderately sound, though the current draw is a tad bit substantial, so a brand new 9 Volt battery will simply manage in the vicinity of one hour,.
The “Cell Kill Distance” is around 10 – 15 ft, sufficient for most grounds.
