Simple Mobile Phone Jammer

Her e may be a straightforward movable transmitter Electronic Circuit Project. Circuit showing a movable transmitter. Here I actually have used a fm junction transistor for creating this circuit. Mobile phones area unit operating in 450 megahertz frequency

Simple Mobile Phone Jammer Circuit Diagram:

Here the transmitter generate almost equal to 450 MHz  frequency there for the mobile phone does not identify the original signal but the signal range is very week so this circuit working in only 100 m range .This circuit working in only 450 Mhz .Do not give more than 3 V.

How to Make a Solar Top Robot (1)

Here is Simple Electronic Solar Project of  Top Robot (1) Make a Robot is not easy, but also not very difficult. Here we start from an easy example – Solar Top. It has below function:

    Rotator under sunshine
    Come back if meet Obstacle
    Keep stay in no sunshine place.

This is a simple automatic robot. It don't need people maintance. The life is depend on the environment and mechanical wear. The parts cost is very low.

The following is the parts you need:

    Clip  6 units
    Mini Motor  1 unit
    Capacitor  3 units
    NPN Triode  1 unit
    PNP Triode  1 unit
    2.2K resistance  1 unit
    LED light 1 unit
    Some Wire
    Small Solar Panel ( >4V, 10mA)  1 unit
    Some Solder Wire
    Perforated Board 1 unit

Below is the robot circuit diagram:
