    Hi,

    I wanna convert the 12 volts DC in my car to AC 110 volts
    60 Hz so I can use my appliance inside the car, what's the
    simplest circuit lying around in the net where I can build
    one? Pls. mention some sites and schematics as well as the
    IC. All I know is the 555 timer ic, but it doesn't up
    the voltage from 12 to 110 volts.

    To make the circuit simpler, can I just use 30 Hz, I
    guess my appliance would still run at this frequency
    right? For electric fan, would it run slower at 30 Hz
    versus 60 Hz or the same? How about light bulb. Would
    it flicker at this lower frequency?

    Thanks.

  2. Lorr,

    Sorry, but from your questions I can only conclude that you don't have the
    skills and knowledge to build such a thing from scratch. You can find
    several solutions on the net but you can't judge what's good and what's not.
    The cheapest and the least dangerous solution is to buy the thing.

    As for your other questions:
    - 30 Hz is not simpler
    - Most appliances made for 60Hz will not run on 30Hz.
    - A 60Hz fan motor will most likely be fried when used at 30Hz
    - A incandescent lamp will flicker at 30Hz.

  3. You can buy a suitable inverter much cheaper than you can build one,
    particularly given the level of electronics knowledge your questions
    indicate.

    To select an appropriate inverter, you will need to determine the
    power required by your appliance.
    Most devices designed for 60 Hz will not operate correctly (or maybe
    at all) at 30 Hz, and an incandescent light bulb would probably have a
    noticeable flicker.

    I agree with the other suggestions. Also, you can probably find a small
    inverter from $25 to $40. You did not mention what the appliance was, but if
    you try to run something that requires a lot of power from the cigarette
    lighter you will probably blow a fuse. And you may lose something like 20% of
    the power through the inverter.
