Many companies online claim that they are making a shield/jammer for rfid and since Rf is like RFID and it gives off a frequency of 58khz it should be easy to jam It is against the law to jam radio communications. Maybe if you are in the middle of a huge desert then nobody will be jammed and it won`t matter. But I don`t think your very simple...
TV remote control blocker/jammer circuit diagram
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 transistor acts as a current source supplying roughly 25mA to the infra red LEDs. To increas

Circuit Diagram of Mobile Jammer
Cell phone jammer is an electronic device that blocks the transmission of signals between the cell phone and its nearby base station. By using the same frequency as the cell phones, the cell phone jammer creates strong interference to the communication between the caller and the receiver. It is efficient in blocking the transmission of signals fro

fm radio jammer
This is VERY illegal. As a consumer, you MUST comply with part 15 of the rules and regulations. Part 15 states that your device must accept any interference received, and it cannot cause any harmful interference. (Such as jamming an FM signal. ) It is even more dangerous when you are jamming FM, since pretty much all radio stations are licensed. Wh
RF Jammer Diagram
This also Not a Cell phone jammer. Jamming a Cell phone is similar on its principle, but totally a different build, you need a range from 800MHz to 900MHz. You need an OP amp and a few other parts and formulas The Radio Jammer sends out a EM wave at a frequency. The wave is then broadcast throughout an area. Radios will receive this wave (when tun
TV Remote Jammer!
A circuit that will block my TV and any device I choose from getting a signal from the normal remote control. I turn an ordinary remote into a jammer and the remote still works normally! Watch the video to see it work. I chose to use a Sony remote control (SR-P30) because it has plenty of room inside to add my circuit and a 9 volt battery while...

TV REMOTE JAMMER CIRCUIT USING 555 TIMER
A Tv remote jammer circuit, using NE555 timer IC. By using this you can watch your favorite TV channel without any interruptions. Ie; No one can be able to change the channel by means of remote, if the circuit remains ON. The circuit is simple to make at your own home, with very low cost. Let`s go deeply into the specification and requirem
TV Remote Control Jammer
This is a very easy circuit that every one could make and have fun. This project popped out of nowhere, one day that i was trying to control the TV from the serial port of the computer. It took me no more than a few minutes to understand the simple method that the remote controls work, and even less time to make a circuit to have fun with my girlf
A laser pulser using the same laser diode LI does. I made the pulser so it could be adjusted from 50 to 20, 000ppm. I tested that on my LIs and rx65, they only alert to pulses from about 100 to 200ppm. I also wonder if my pulsure would work as a jammer if I turned the frequency all the way up, sort of like an old brute force jammer that worked...
Radar Detector Laser Jammer
With a GPS receiver that costs less than a few hundred dollars you can instantly learn your location on the planet-your latitude, longitude, and even altitude-to within a few hundred feet. The output of the VCO is directly connected to a MMIC IC3. This IC amplify the RF signal and feed it to the antenna. The power to the MMIC is feed from R3 and...

Ultrasonic distance finder circuit
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 measured. There are three main categories of distance measurement methods in use: a) By...
Simple Metal detector circuit with CD4030
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 find something potentially valuable, hidden a few centimeters below the soil. So many...
Fully automatic watering circuit for flower pots
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 circuit comes as a solution to this problem. Depending on humidity of the pot at...
Simple deep searching metal detector circuit
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 circuit of this metal detector, it is possible to detect a metal coin in depth of 90 to...
Sub-Harmonic Bass Converter for Electric Guitars
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, such as filtering or distortion. Instead, a frequency division system produces outputs...
Echo Depth Sounding Sonar for Boats
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 calibration of the rope. This arrangement still exists in some yachts. The big...

Analogue Sound Preasure dB-Meter Circuit
The best human ear can capture sounds from 20Hz to 20KHz. These limits are known to be the broadest that can exist. Normally the normal limits range from 100Hz to about 13KHz and depend on the age and health of the individual. We for our measurements and to have a good accuracy we will get the limits of 20Hz to 20KHz. A sound to be heard does...
