This video is amazing,  teaching you how to make an emergency lamp out  of the power in your phone line , it says that a phone line as near about 50 to 60 volts of power and as the phone line never goes down, even if your electricity goes out, you can have an excellent emergency lamp.

Now , I hope you can add one more gizmo to your list of self-made gizmos and show it to your family !! ( Techstroke.com  – smart@Technology )
