    I am wondering if it is possible to operate a 24vdc mister on 12vdc?

    Something simalar to this:

    Item: MDC01; DC powered mist maker
    Transformer Input: AC110V; Output: DC24V
    UL. CUL. listed. Fogger size 1.5"(dia) x 1.25"(h),
    great for small shallow water container.

    I've been doing a little reading on what it takes to run the piezo
    element and the oscillator circuits and I'm not very knowledgeable
    with circuits and I'm not sure if these will work on 12v.

    Thanks in advance for any advise on this.

    Probably not. Why do you want to run it from 12V anyway?

    Cheers.

    So I can run it off a 12V battery. I suppose I could pick up a DC/DC
    step-up, or just keep looking for a 12vdc mister, but most of them are
    24V and 36V AC, and I'm not really up to wiring on up and getting one
    that works. It doesn't need to be like the one shown I would prefer
    one that I could build into a reservoir like the ones in a ultrasonic
    humidifier.

    Make your self a simple voltage double circuit!
    That is, if you're up to it.

    A complemary pair of Power Logic Fets being driven from
    some simple square wave oscillator like a 555 timer should
    do it, along with the proper diode and cap configuration of course.

    I've done this before running low demand devices that were
    24V dc, in the car.

    I used the output as part of the gate driving voltage so the
    initial start up was a soft ramp to 24 volts but it made it easy
    to supply the needed voltage to the gates of the fets.


    The last one I did used a small pic to monitor the current load
    in a battery charger for an HT that has a 12 volt battery pack in it.

    A charge pump booster as the charger .. word out well actually.

    You could run it off of two 12V batteries connected in series.

    look it is a matter of power if it run at 12 v it will never run as good as a 24v.that seems simple to me.
