Instrument Development

I would like to build a set of instruments to read eight
sensor inputs (0-5vdc real time) then translate that
information to drive eight R/C servo motors that will
position dial indicators showing the input values. In your
opinion what equipment will I need to do this.

I am not familiar with the Basic Stamp other than its
existence. Any information and/or resources would also be helpful.
It seems that this should be an easy thing to do!? These
instruments will be in a harsh environment, i.e.. vibration,
electrical noise, 0-50C, and need to be small in size.

Any help will be much appreciated.

Sincerely,

Dave

    Dave,

    The MAX186 is a 12-bit - serial - 8-channel - ADC that would work
    for your application, and interface to the Basic Stamp.

    Have a look at the datasheet:

    Wow, this seems like alot of moving parts just to display values. Can you
    use a digital display (LED or LCD) to display the values? This would be
    easier, more accurate and more reliable. There are numerous
    easy-to-interface (serial) display options available. You could read the
    analog values with a MAX186, do a little math and then send a scaled
    reading to a digital readout...

    Again, any moving parts are going to potentially suffer more than a sealed
    digital display.
