E- Waste is going to be generated in large quantity due to the evolution of technology.

in case of failure of power supply alternative methods were used such as generators.Frequency Counter Circuit:Frequency counters measure the frequency of a signal.

Voltage Doubler Circuit:This is another kind of circuit which helps to convert 12V DC to 24V DC.An LED or a buzzer (or both) can be used to indicate the event (the event is door-bell being pressed).It employs a closed-loop control technique.

It is a light-sensing device as it uses a light-dependent resistor.we will review and publish here.

6V to 12V DC Converter:This article shows the circuits for converting small voltage to higher voltage that is  6v DC to  12v but with a lower current rating.

Smoke Detector Alarm Circuit:Here is the circuit showing a smoke detector alarm.The highly efficient i7C series converters accept a very wide DC input and has a wide output adjustment range

The highly efficient i7C series converters accept a very wide DC input and has a wide output adjustment range.A baseplate version for conduction cooling to a cold plate is 13mm high

Up to 87% Accepts a wide 90 to 264Vac input Input to output isolation is 3.The KPSB6 has an off-load power consumption of less than 75mW and the KPSB25 100mW.
