    Are there any free/shareware or inexpensive (under $100) sofware packages
    that let you design circuits and analyze various values (V,I,R for instance)
    at points in the circuit? I'm trying to learn and something like this would
    be invaluable to understanding.

    Hi teranews,

    I have used Circuit Maker the student version ('cause I'm a student) I
    find it useful and it works good. You can download it from their site:

    SuperSpice, a very affordable Mixed-Mode
    Windows Simulator with Schematic Capture,
    Waveform Display, FFT's and Filter Design.
  5. See my notes and links to some 60 ECAD programs at

    Quite a few of those have the sort of analysis facilities you want.
    (They are all based on a standard program called Spice.)

    I personally use CircuitMaker Pro, but that is above your price range.

    An excellent free program, highly recommended in these groups, and
    with easily-accessed support here and in online forums, look at LT
    SWCAD III (SwitcherCAD III). It can be downloaded from
