    Hello,
    I am new to news groups and to hobby electronics,I dont want to sound
    stupid but I've gotta ask "How do I veiw schematic diagrams?" All I see
    are some dashed lines.

    If you're talking about schematics done in ASCII, you need to view
    them using a non-proportonal font like Courier, then you need to
    learn how to interpret them. For starters, the dashed lines are
    wires, and the components can usually be identified by their values
    or reference designators.

    For example, this is a schematic for a thermostat:

    +12V>-----+-------+---------+--------+----+-----+
    | | | | | |
    | | | [10k] |K | O------C
    [4k7] [30k] | | [CR1] [COIL]- - -|
    | | +---|--[1M]--+ | | O--> |<--O--NC
    | | | | | +-----+ |
    | | | | | | +-----------NO
    +---+---------+--|+\ | D
    | | | | >------+--+-----G 2N7000
    [RTH] | [10k]<--+--|-/ LM319 | S
    | | | | | | |
    +---+ | | | | |K |
    | | | | | | [Z15V] |
    | [4k7] | [30k][0.1µF]| | |
    | | | | | | | |
    [0.1µF]|[0.1µF]| | | | |
    | | | | | | | |
    GND>--+---+---+---+-----+---+-----------+-------+

    If you view it in Courier you should have no problem reading it.

    That is, if you can read schematics in the first place. ;)

    If you're using Google Groups, it shows messages in a typeface (font)
    that scrambles the patterns the posters went to such trouble to create
    using a "nonproportional" font. In a nonproportional font, every
    letter has the same width. This creates a grid and makes it possible
    to draw straight lines and such to make a schematic diagram.
    I think if you are using Google and you look at the upper right corner
    of the page and click on "nonproportional," you may be able to convert
    the view such that it will make the images recognizable.

    I do a Save As... and save as a txt file so Notebook (or whatevery you
    use for text files
    on your computer) will open it. then they are readable.

    Or, maybe there's a way to make Outlook Express display in Courier.

    Good question as I too was wondering how in the world people are
    reading those schematics. Thanks for the question and the heads up.
    It looks fine now.

    In Outlook Express, go to :
    "View"
    "Text Size"
    click on "Fixed"
    and the schematic is the readable.
