The post explains a mosquito bat swatter circuit which can built at home and used for zapping mosquitoes or similar flying pests.
The circuit uses only single Transistor but good voice quality. This Circuit is very simple and uses few components. Main part of the circuit is LC ( Coil Capacitor. The proposed long range transmitter circuit really is very steady, harmonic free design which you can use with standard fm frequencies between 88 and 108 MHz.
This the fm wireless transmitter circuit, the truth is one kind microphone that developed to be used without a cable from the microphone to the amplifier. This lead acid battery charger circuit is designed in response to a request from Mr.Devdas .C. His requirement was a circuit to charge two 12V/7AH lead acid … Build a Circuit. A circuit is a path that electricity flows along. It starts at a power source, like a battery, and flows through a wire to a light bulb or other.
