My Light Diagram

Here is a simple circuit diagram of mobile signal jammer. This circuit analysis is simple and easy. For any jammer circuit , remember that there are three main important circuits. When they are combined together, the output of that circuit will work as a jammer. The three circuits are RF amplifier. Voltage controlled oscillator. Tuning circuit. So the transistor Q1, capacitors C4 & C5 and resistor R1 constitute the RF amplifier circuit. This will amplify the signal generated by the tuned circuit. The amplification signal is given to the antenna through C6 capacitor. Capacitor C6 will remove the DC and allow only the AC signal which is transmitted in the air. When the transistor Q1 is turned ON, the tuned circuit at the collector will get turned ON. The tuned circuit consists of capacitor C1 and inductor L1. This tuned circuit will act as an oscillator with zero resistance. This oscillator or tuned circuit will produce the very high frequency with minimum damping. The both induct...

The 4 - 20 mA signal is an extremely popular signal specification in instruments. The 4 to 20 mA signal provides "live zero" function. i.e. in the event of a wire break, the signal drops to zero mA. This can be used to detect wire break or sensor failure. This is a crucial advantage of the 4 to 20 mA format. Being a Current signal, it is also less susceptible to external interference. The 4 to 20 mA format works by varying the resistance to a constant source voltage. The sensor consists of a transistor which regulates the current passing through it in accordance with the measured value. Sensors which use this format can be categorized into active and passive transducers. Active transducers are devices which can provide the system voltage as well as regulate the current. Passive devices require an external voltage and only regulate the current. Another advantage of this 4 to 20 mA format is that it can be easily converted into a voltage signal by means of a res...
