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!!!!

Step 1: Components & Tools Required

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.

Step 2: Circuit Diagram

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....

Step 3: Placing the Components & Connections on PCB

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...
