Jammer Circuits
-
This Jammer circuit can be used indoor or outdoor and the coverage/range that offers is about 30 meters in order to disconnect the wireless devices from their communication with the base station. In the circuit design, we use the frequency ranges reserved by.... -
There are still neighbors that keep annoying you by having loud the TV or the radio? Well I have you the solution. In fact all neighborhood will face your jamming waves at their TVs and radios, so be careful. This Jammer is the improved version of the old.... -
** UPDATED 2014 ** This project is the original High power mobile phone Jammer circuit, and all updates are posted here. All other versions are just copied from next.gr. First off all you should be very careful how to use this device. Its fully illegal and.... -
The Jammer is a very small circuit and can fit inside a small plastic box with 9V battery inside. It can be very illegal if you attach an external antenna so don't. adjust frequency by turning trimmer. It is intended only as a practical joke device. The.... -
This cell phone jammer is not applicable for use in Europe, Middle East, nor Asia. The GSM jammer circuit could block mobile phone signals which works on GSM1900 band, also called DCS. For more cell phone jammers check the related posts... -
This Remote control Jammer device it’s useful when we need to block someone to use the remote control (children that change frequently the channels at tv). This remote control jammer it’s very simply and it use two infrared Leds which continuously transmit.... -
Here is the circuit diagram of simple but highly effective TV remote jammer circuit. Most of the TV remotes have 38KHz operating frequency. A flood of IR beams in the same frequency can easily confuse the TV receiver and this is the operating principle of.... -
Hackers listen up. Everyone understands and enjoys the utilitarian benefits that GPS has brought to our lives but what if it didn’t work any more? I suppose you could build some sort of surface to space missile robot that would systematically seek and.... -

Just point this small device at the TV and the remote gets jammed . The circuit is self explanatory . 555 is wired as an astable multivibrator for a frequency of nearly 38 kHz. This is the frequency at which most of the modern TVs receive the IR beam . The.... -
The IR Jammer is a fun project that provides a bit of safe, non-destructive fun. The Infrared Remote Control Jammer allows you to render all IR remote controls inoperative! The microcontroller in this design allows for all 6 of the main IR frequencies to be.... -
A wonderful diy gsm jammer or cellular mobile phone jammer schematic diagram for use only in GSM1900 with frequency from 1930 MHz to 1990 MHz. The GSM1900 cellular cell phone network is made use of by USA, Canada and most of the nations in South America..... -

A wonderful diy gsm jammer otherwise cellular mobile phone jammer schematic diagram instead of application single taking part in GSM1900 with frequency from 1930 MHz to 1990 MHz. The GSM1900 cellular cell phone meet people is made use of by USA, Canada and.... -
This circuit 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.... -
A beautiful diy gsm jammer or mobile cell phone jammer schematic diagram for use only in GSM1900 with frequency from 1930 MHz to 1990 MHz. The GSM1900 mobile phone network is used by USA, Canada and most of the countries in South America. This cell phone.... -

Breadboard and test the DIY IR jammer last weekend but it`s taken me this long to carve out a minute to post the results. The schematic is correct and only took a few minutes to re-create on the plugboard. For power I used a small bench supply set to 6 volts.... -
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.... -

This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of.... -
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is.... -
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to.... -
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This.... -
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the.... -
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,.... -
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the.... -
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power.... -
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
