    NEW Small DC-DC Power Supply

    I have see lot of request for power supply to give 10 to 14 volt

    If you can make electronic you can use this simple schematic

    It got because you connect to you car battery directed, It not make lot of heat

    The some of the part I get as free sample
    Other part I get from old pc power supply

    This power supply will cost my max. 5$ and 1-2 hours work

    I think small cost is good
