Step 1: You Need to Make

4v rechargeable battery

4v SMD LED 6 X2 = 12 piece

nokia charger socket

led & 220 ohm resistor for charging indicator

1N4007 diode

wire

switch

plastic box

glue stick

& any thin pin charger for charging

Step 2: Connections & Making

here I use a normal led for charging indicator so I use a diode & 220 ohm resistor for it

connect all components as per the circuit diagram

fit all in a plastic box.I use 12 4V SMD LED

you can watch making video & please subscribe my youtube channel also
