What is 555 IC signal jammer?

The 555 ic signal jammer we made is capable of blocking the signals of a cell phone when placed near it. The signals coming from the jammer circuit we made get interfere with the radio waves coming from the cell phone which results in the blocking of cell phone signals. Hence the phone is unable to communicate with the respective towers.

What is NE555 timer?

NE555 is a high precision timer IC. The IC is capable of operating in three modes, astable, bistable & monostable. The IC possesses an oscillation frequency ranging from 670 to 680 Hz. Here, the NE555 timer acts under astable multivibrator mode. An astable multivibrator is a free-running square wave signal oscillator.

What is a mobile phone jammer or blocker?

A mobile phone jammer or blocker is a device which deliberately transmits signals on the same radio frequencies as mobile phones, disrupting the communication between the phone and the cell-phone base station, effectively disabling mobile phones within the range of the jammer, preventing them from receiving signals and from transmitting them.

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.
