    Hi everybody
    my name is Rudy, coming from switzerland but living in Romania.

    I have a device (HHO box) that I would like to run in the car from the battery, but only when the engine is running. That means when the battery has about 13.8 V.
    When the engine is off is has about 12 V. Then no current should flow.

    It should with a turning knob limit the ampere, so that a maximum of (3 ... 15 ampere needed for selection) is going trough.

    I am not an electric, has somebody an idea?
    can somebody build one for me?
    or where I can buy such a thing?

    thanks, Rudy

    Double Whammy!

    We should have a contest about how many TOS violations we can put in a single post...

    Just wondering where you buy such an HHO box, how much it costs, and what have you done with it so far. A link to the HHO supplier's website would be really interesting.

    HHO and overunity are both not allowed here either.
