    I've taken basically, only my introductory course in DC electronics.

    How far away am I from being able to accomplish this? What additional knowledge of electronics will I need?

    I want to make analog and digital versions of them.

    I have a larger project in mind that includes those items...

    Analog meters are probably trickier to make mechanically than electrically.
    It's like a coil of wire on a piece of magnet with some springs. You need to calibrate it so it points where it should.

    You can buy some panel mount ones for a few dollars if you want to use them.

    Check into Wheatstone bridge circuits. These can be built around an old analog panel meter........ a VU level meter culled from one of the fancier stereo multiplex units

    That oughta have you tearing you hair for a few days :D
