    greetings to all elec. techs.
    im a bit of a nerd with things electrical. very limited understanding
    could some one dispel my doubts a bit?

    1 im making a 6 plate hho gas generator and rather than buy a power
    adaptor---i just use my laptop adaptor
    output 19.5v 3.9a with a round tube-like jack
    is it just a matter of buying the femail jack and soldering my 2 wires
    from the hho cell to the femail part---are there specific pos and neg
    on the femail jack?
    and can i put a rheostat on the wire to control the amount of volts
    im putting into the cell? would it damage my adaptor in any way?
    also i want to put an on off switch along the powerline

    2 also i will buy a small high pressure aquarium air pump with an
    attatched power plug i can put directly into the mains
    sometimes i might not want full high pressure air coming out
    if i use a rheostat ---would it harm the pumps engine? should
    it be a special kind of power controller?

    any advice appreciated

    If this is for automotive use (why else would you be building an HHO generator?) then the mods will probably close the thread.

    Sorry, we do not discuss HHO systems on AAC.

    This thread is against the AAC forum rules, Chapter 6, as seen here:

    This can be found in our Terms of Service (ToS)

    We'll be happy to discuss any other aspects of electricity or electronics that do not violate AAC rules.
