on video How to make a joule thief circuit || DC voltage boost circuit


 In this video, I am showing you how to make a DC voltage boost circuit also known as the "Joule thief circuit". This circuit can boost very low DC voltage to very high output voltages. With this circuit LED bulbs can be powered even from dead batteries.
        This circuit is made from components from old CFL Bulbs. A Joule Thief is a self-oscillating voltage booster. It takes a steady low voltage signal and converts it into a series of high frequency pulses at a higher voltage.
