Make Mobile Signal Jammer Circuit At Home Circuit Diagram Useful steps. 1) solder the bf494 transistor on the vero board & solder a 22nh inductor to its collector pin. 2) solder a 15nf capacitor on the collector of the bf494 to vcc of the circuit. 3) solder the two 4.7pf capacitors in parallel between collector & emitter of the transistor. Increase the frequency of tuned circuit by using this formula f= 1 (2*pi*sqrt (l*c)). increase the inductor capacitor circuit components value for increasing the frequency. get guide on mobile phone jammer circuit and its working. this circuit works in the range of 100m. and blocks the signals of cell phones.
How To Make A Mobile Signal Jammer Using A Transistor 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. this capacitor blocks the dc and allow the ac signal to pass which is amplified by the transistor q1. The use of different frequencies makes it difficult to have a jammer for all frequencies. however, the below mentioned formula can be used to calculate the required values. f = 1 (2*pi*sqrt(l1*c1)) depending on the frequencies you need to block, the values of the inductor (l1) and capacitor (c1) can be altered. How to make a mobile network signal jammer using 555 timer ic and etc, network jammer, phone jammer, this project is very interesting and simple circuit foll. Useful steps. 1) solder the ne555 timer ic on the veroboard. after that, solder the toggle switch on the veroboard. 2) after that, solder the 30pf trimmer capacitor on the veroboard. 3) solder the 4.7uf capacitor with pin 3 of the ic. after that, solder the ve terminal of the led with vcc of the circuit and ve with 1k resistor.
