What is a "Signal Blocker Circuit"? The Most Authoritative Explanation.
What are the parts of a signal jammer circuit?
For any signal jammer circuit, there are three main parts in the circuit and when combined together the output of that circuit will work as a jammer. These three main circuit parts are RF amplifier. Voltage controlled oscillator. Tuning circuit. The entire cell phone signal jammer circuit can be powered up using a 9V battery.How does a cell phone signal jammer work?
The entire cell phone signal jammer circuit can be powered up using a 9V battery. The Switch S1 is used to turn ON and turn OFF the cell phone jammer. In the above circuit the 555 Timer is used as the Frequency generator. The output of the 555 timer is fed to the amplifier circuit through a 1uf electrolytic capacitor.Is it illegal to block a cell phone signal?
In most places actively blocking any kind of communications is illegal. So if you plan on using this circuit make sure you check your local Laws and Regulations. This DIY Cell Phone Signal Jammer Project is only for the Educational Purposes. *Please Note: These are affiliate links.How does a 555 timer work?
The output of the 555 timer is fed to the amplifier circuit through a 1uf electrolytic capacitor. This capacitor blocks the dc and allow the AC signal to pass which is amplified by the Transistor Q1. The amplified signal is then given to the antenna through a 4.7pF capacitor. First Coil- 4 turns 5mm of 24 AWG wire.
