Alright.. So can someone explain to me what each part of a joule thief does? I understand the LED, Resistors and battery Answered
So, in a recent Instructable about a Joule Thief, I was slapped in the face with a gap in my knowledge. I have no idea what the toroid DOES, I know it's an inductor... but is it suppose to transform low voltage to higher voltage? What happens If I wind it more? How about less?
What does the transistor in this setup do?
In a recent Instructable, as I was saying, they did it with only a regular inductor.
I'm in the middle of finals too, my brain feels over used...
