    Hi all,

    I'm a newby here and only have a fairly basic electronics knowledge.

    What I am wanting to know is how to convert a variable resister to a variable voltage output, very low current draw as it just runs an electronic fuel gauge.

    The output of the sender varies from 10 ohms (empty) to 149 ohms (full).
    The input to the gauge needs to be 0.1v empty and 4.5v full.
    Supply voltage is a regulated 12VDC.

    I played around with a resistor calculator but couldn't find that happy medium.

    Can any one help me with this? Can this be done simply or will it require something a little more elaborate??

    Thanks in advance!

    Matt

    Sounds like a car app so I would expect the moderators to jump straight on this request and kill this thread.

    Why?

    Are car electronics different from other electronics??:confused:

    No it's just the rules of the forum, no car electronics.

    I did read the posting rules on the sticky but did not mention this?

    Oh well, delete way if that's the rules.

    And you are so right.

    The owners of All About Circuits have elected not to allow discussions of automotive electrical system modifications/enhancements due to safety concerns, the potential of legal ramifications and the possible circumvention of vehicle regulations at the state and federal level.

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

    6. Restricted topics. The following topics are regularly raised however are considered “off-topic” at all times and will result in your thread being closed without question:

    • LEDs to mains
    • Phone jammers
    • Rail guns and high-energy projectile devices
    • Transformer-less power supplies
