    Hi I was watching on youtube a kind of Tesla coil, Called Mini Tesla Coil,
    this is the video:
    And This is the diagram:
    [​IMG]

    How it is possible from a DC battery get High Frequency without oscillators?
    In other words, in this diagram How the High Frequency is got ?


    This question is for experts only, Do not answer if you don't know it.

    Welcome to EP.
    "How it is possible from a DC battery get High Frequency without oscillators?"
    It isn't, the circuit oscillates roughly at "single" Mhz frequency!

    "In other words, in this diagram How the High Frequency is got ?"
    The coils actually form a transformer (coils are opposite directions wingdings!)
    The circuits relies on the very small parasitic (stray) capacitance of the large coil to GND. It isn't drawn in your circuit diagram.

    See, it didn't take an expert, did it?;)
    BTW,
    This circuit is called a "Slayer Exciter"

    Still I don't get it, in the circuit it is not necessary to connect the large coil to GND, (it is demonstrated in the video).

    The important thing is, Which are the electronics components that changes the direction of the current and how?

    Can you explain it step by step in a easy way to understand? (I m beginner)

    Well,
    I guess you wouldn't like someone to chew the food for ya, would you?o_O

    Here is a video to start with.

    If you are a beginner and wont to learn ,you have to do it by yourself.
    Identify the elements of the oscillator by yourself,
    after you do and understand it basically ,come back for "minor" questions.;)

    I didn't know that's what they were called xD
    I would have kept looking for 'pocket tesla coil' or something similar.
    Just visited google... didn't even need any google-fu to find tons of circuits, tutorials and info on these things.

    I was starting studying it through internet, I dont need someone to chew the food for me, just a little of help, I think for a person who understand the circuit will be able to explain it and it could be using few text since the circuit only there are just 6 electronic components, anyway, I was starting researching on internet but there are not good explications.
    I m beginner but not too much.

    Electroboom is fing hilarious
    anyways, the switch kind of acts like an oscillator, so yeah there is an oscillator.

    since I'm not an expert in Tesla coils your request prevents me from doing any research to help you.
