AUTOMATED ALARM CIRCUITS
ACKOWLEDGEMENT
Through perseverance and enthusiasm combined with effort in the right direction can bring forth the thing called success but the realization of the harsh reality that the path towards success is full of myriads, temptations, impediments and pitfalls often proves to be disheartening in such situation, it is the able guidance of knowledgeable persons that steers one through difficulties and help her achieve success.

ABSTRACT
From the late 19th century through the middle of the 20th century, DC to AC power conversion were accomplished using rotary converters or motor – generator sets. In the early 20th century, vaccum tubes and gas filled tubes begin to be used as switches in inverters circuits. The most widely used type of tube was the thyratron.
The origins of electro mechanical inverters explain the source of the term i ....etc

The theory behind this circuit is quite simple and amazingly effective. When female mosquitoes (the ones that bite you) are pregnant they prefer to stay away from male mosquitoes and search for food (your blood). The circuit reproduces the ultrasonic noise that a male produces, this in turn repels the female mosquitoes
In the circuit diagram of an ultrasonic mosquito repeller.The circuit is based on the theory that insects like mosquito can be repelled by using sound frequencies in the ultrasonic (above 20KHz) range.The cir ....etc

Two alarm circuits are presented here. One produces bird-chirping sound and the other British police siren tone. Fig. 1 shows the circuit of the birdchirping- sound alarm unit along with the circuit of the control unit. Fig. 2 shows the circuit of only the British police siren tone generator, which has
to be integrated with the control circuit portion of Fig. 1 at points A and B to complete the circuit diagram of automated alarm
