Today I am going to show you how to make emergency Flashlight / Torch at home using old mobile phone battery.
I made this for myself and using regularly, I can use this Torch upto 5 hrs after full charge.
I have made a video showing of all this, you can watch this video for more information ...

1] Old mobile phone battery (you can use new also) (I am using 3.7v 2000 mah battery)
2] USB male port 2.0
3] LED (3.3v 1watt) and heat sink
4] Resister (1.5 Ohms 5%)
5] On / off power switch
6] Some pieces of wires
7] Solder gun, and
8] Hot glue gun.
Circuit Diagram ...
(In this circuit diagram, please read resister instead of register)
So let's start now:
First, take the battery and connect the wire to its positive and negative terminals. Do not allow the battery terminal to interconnect ie do not short. do not place the solder gun on the battery while soldering.
To connect the LED, find its positive and negative terminals and connect a wire to its +ve terminal.Then attach the LED with the heat sink with help of solder gun to solder.
After that connect the resister on the negative side of the LED and the other end of the resister on the negative side of the battery, you can put any terminal of the resister on either side.
Then connect the positive wire from the battery to the power switch and connect the wire to the positive terminal of the LED on the other side of power switch.
Connect the negative to the negative of USB and battery and positive to positive of USB and the power switch, we have already connected other terminal of power switch to +ve terminal of battery.
7] Solder gun, and
8] Hot glue gun.

Connect the negative to the negative of USB and battery and positive to positive of USB and the power switch, we have already connected other terminal of power switch to +ve terminal of battery.
Now our circuit is complete. We have to stick this circuit over the battery. For this, we will use hot glue.
You can charge the battery.
While pasting the USB on the battery, we have to keep in mind that after pasting, we can easily place it in the charger.
Voila! Our Flashlight/Torch is reday.
