Do you know how to work his usual power saving devices in the market is shaped like a dry battery with a plug into an outlet?. Actually you can create your own tool with much better quality with much cheaper price.



Because of the way it works is to reduce the magnitude from cosine curve AC current that will be read on the gauge kilometer. Device work if there is air conditioning load passes through a coil of wire sensors to measure the AC current which is being passed.

A very influential component in the AC circuit is a capacitor and inductor. Therefore we need to filter the AC current before it enters our home electricity network. Obviously we did not perform the act of theft of electricity, and this tool will not be detected by the device are as follows . How to installation, Here I would include a scheme of the circuit which will be installed close to the mile. The closer, the more optimal the way it works, use good quality capacitors, for security MCB here, serves to prevent the occurrence of shorting out due to damage to the capacitor. Then Enter in box or plastic box which is strong enough. Better capacitor in the cast by GIPs or cement, so that power is wasted heat well.

Standby Electric Generators for Emergency Farm Use Susan W. Gay, Extension Engineer, Biological Systems Engineering, Virginia Tech An emergency source of power is essential for any farm with mechanically ventilated production facilities, bulk milk-handling equipment, automated feeding systems, or facilities requiring constant and consistent heat or refrigeration. A standby power generator is an excellent investment to prevent costly losses during local power failures.

This is a design circuit diagram of a moderate power FM transmitter circuit. This circuit is built operation by two transistors. This is a figure of complete circuit.


Operation of this circuit is explain as the voice signals picked by the microphone will be amplified by the transistor Q1.The second transistor is wired as an oscillator operating in the FM band. The output of T1 is given to the base of T2.T2 performs the modulation also. The tank circuit comprising of components L1 and C6 determines the frequency of the signal, and can be varied by adjusting C6.The capacitor C7 couples the FM signal to the antenna. The inductor L1 can be made by making 6 turns of 0.8mm enameled copper wire on a 5.5mm diameter/4.5mm length plastic former.

With a matching antenna and proper tuning this transmitter can have range up to 100 meter. The Antenna A1 can be a 1M long wire. The circuit can be powered from a9V PP3 battery.

The series of emergency lights on this one is a series of emergency lighting is quite simple and not difficult to make. 

Frankly this circuit is not my own design, but at least this series can add to your collection of electronic circuits. The circuit is actually almost the same as the battery charger circuit, its just that in this emergency coupled switching circuit as a circuit breaker when the circuit load is connected to the supply voltage of 220 volts or in other words on the charging position. Meanwhile, when the voltage of 220 volts is lost (PLN lights off), then automatically switches the load switching circuit and turn on emergency lights, where the supply that is used is derived from batteries that have been installed in stand-by position.

In a series of emergencies over the use of LED as a lighting load emergency. And indeed these days we find a lot of emergency lights that are sold in the market that use LEDs, but the LED is used instead led carelessly but has led a gleam of light. The advantages of the use of this led the led is very efficient because once will consume battery power so that with a limited supply to run the series in a long time.

Circuit components used for emergency lighting is not too much, and indeed the components used are the components that are commonly used as components for circuit switching power supply and battery charging. IC LM 317 ic regulator is useful as a producer of supply voltage to supply the batteries. Transistor T2 (BD 140) is useful as switching, ie, decide the flow toward the load at 220 volts PLN lamp life so that lighting will be extinguished. But when the lights PLN did not provide the supply voltage of the transistor T2 will connect the connection from the battery to the load light.

Components used:

Resistors: R1 (180 uhm), R2 (1.2 K), sd R3 R14 (100 ohms), R15 (1 K) and R16 (16 ohm, 5 watt)

Capacitors: C1 (1000 UF)

Diodes: D1 until D5 (IN 4007)

Transistors: T1 (BC 548) and T2 (BD 140)

Zener Diodes 6.8 Volt

IC: LM 317

Battery charger

Transformer

If you are not happy using this type of charger with IC LM317 series like the example above then you can use another type of charger circuit that you think is more appropriate and can work optimally. Then you simply add the switching function by using one or more transistors.

This is the circuit diagram of a 3 LED bar graph type battery
monitor circuit that is ideal for monitoring the voltage level of an
automobile battery.When battery voltage is 11.5V or less transistor Q1
will be On and the LED D1 will be glowing.When battery voltage is
between 11.5 and 13.5V, the transistor Q2 will be On and the LED D2 will
be glowing.When battery voltage is above 13.5V the transistor Q3 will
be On and the LED D7 will be glowing.

Circuit diagram with Parts list.

Assemble the circuit on a general purpose PCB.The battery to be
monitored can be connected between the terminals namely A and B.It is
always better to use LEDs of different colour.
