1. This circuit is low power inverter circuit and consist of 9
component.
2. The output is available at IC 556 pin 5. The second section is
wired as a phase inverter. That output is available at IC 556 pin
9.
3. Voltage input is 10-16v dc into 50 HZ.
4. And then voltage will be raised to about 230 V with power 25-
30 W. The first section of IC 556 timer chip is wire as an a
stable oscillator with R2 and C1 setting the frequency.
5. The transformer use 230 V / 12 VCT unit that is connected
backwards, so that it steps the voltage up rather than down. At
resistor R3 and R4 keep output transistor Q1 and Q2 from
loading the transistor. The transistor drive the transformer.

Project-2:
The Automatic LED Emergency Light
Objective: To make the “Automatic LED Emergency Light”.
ABSTRACT:
Now days, we have frequent interruption in the main Power
Supply. So here we make a LED Light, which will provides very
bright light which turns on when the mains supply is not there.

Working Principle
The charger power supply section
It is built around 3-terminal adjustable regulator IC LM317
(IC1). In the charger power supply section, input AC mains is
stepped down by transformer X1 to deliver 9V, 500 mA to the
bridge rectifier, which comprises diodes D1 through D4. Filter
capacitor C1 eliminates ripples.
 Unregulated DC voltage is fed to input pin 3 of IC1 and
provides charging current through diode D5 and limiting
resistor R16. By adjusting preset VR1, the output voltage can be
adjusted to deliver the required charging current.
 When the battery gets charged to 6.8V, zener diode ZD1
conducts and charging current from regulator IC1 finds a path
through transistor T1 to ground and it stops charging of the
battery.

18. Objectives: Design of the Foot step Power Generation.
ABSTRACT:
Now days, we have not adequate amount of the fuel for the
generation of the electricity in conventional method (i.e.
Thermal Power Plant, Hydro power plant and nuclear
power plant.
So here we are going to design the Footstep Power
Generation by without using the conventional fuels.

Working
When ever pressure is applied on piezoelectric
sensor
That pressure is converted into Electrical energy
 That minute voltage which is stored in the Lead Acid battery.
 That voltage is used to drive DC loads.
 Here we are using PIC16F778 to display the amount of battery get
charged.
