Bangle Box Converted to Emergency Light

Hello,

This is most useful & small in size emergency LED light made from bangle box

In this instructable i used bangle box & old nokia(any) mobile battery to make this emergency light

it have more features like very small in size &we can carry this any where....it provide high brightness

finally we can charge it by using mobile charger

lets see how to make this!!!!

COMPONENTS:

1.Plastic bangle box-1 no.

2. 3 W LED with heatsink-1no.

3. Old mobile battery-1no.

4. 5mm red LED-1no.

5.general purpose PCB-as required size

6.DC jack-1no.

7.Diode In4007-1no.

8.Resistor 470 ohm - 1no.

9.Switch - 1no.

10.Flat PVC sheet - as required size

11.Screw - 4no's

12.Paint any color

13. Wire - as required size

Tools:

1.Soldering kit.

2.Glue gun with sticks.

3. Paint brush.

4.Wire stripper & cutter

5. Aksha blade

6. Insulation tape.

This is the circuit diagram of this instructable... many of the people already gave this circuit....but here i used the different container to reduce the size and weight to carry any where....

Now place the LED,resistor,diode,on the PCB....while placing LED just place it on corner because we have to project little bit out side of box...then make connection as per circuit diagram...

In this step take the box & paint it .....just leave it on top side alone ..

Now take flat PVC sheet & cut it in the size of bangle box then place the 3Watts LED on it for more details refer attached image.

then cut the flat PVC sheet as required size to fix the battery inside of box..

after that solder two wires on battery (+)&(-) terminals ..for safety purpose glue it and cover with insulation tape..

now give connection as per the circuit diagram..& place the LED sheet on top then screw it all

Now paint top round PVC sheet & closed it

after this just connect the mobile charger at that time red color LED will glow...now battery getting charge& ON the switch 3 Watts LED will glow

everything done.....................
