Several comments:

1  -  You didn't make it all that easy to look at your schematic and reply.
The best way to put schematics on a web page is probably a PDF file.  You
provided an unnecessarily large JPG file within a web page that had frames.
On top of that, the JPG file appeared to be a screen shot of the whole Eagle
window.  Others have no need to see the window title, menus, toolbars,
status bars, and other such waste of pixels.

There was no easy way to view your schemtic on the screen while typing a
reply message at the same time.  Printing out the web page didn't help
either because it was so large that much of the schematic got clipped off,
even in landscape orientation.  I probably should have just hit delete and
moved on, but due to some whim I guess I decided to take it as a challange.
Eventually I saved the image from the web page to a disk file, then printed
that using "fit to page" mode.  That's NOT something I'm going to do twice.

2  -  JPEG format is a particularly poor choice for line art images,
although it didn't get in the way in this case.  GIF is much better when
you've got large flat areas of constant color and only a few different
colors over the whole image.

3  -  NEATNESS COUNTS!  The pervasive sloppiness and lack of attention to
detail says you don't care, so why should anyone else?  This is evident in
the lack of care in putting the schematic on the web site and in the way the
schemtic itself is drawn.

Just *look* at the schematic a bit.  Didn't you notice that the labels for
C2 and C3 overlapped the symbol for IC2, for example?  Other points are:

* The "+9V" label is jammed right up against "IC2" so that the whole thing
looks like one string.

* Much of the text around the thing at the far left is unreadable because
several symbols are jammed together.  (How could you not notice that!?  The
conclusion is that you did and just didn't give a crap.  In other words, to
you we're just a bunch of irrelevant lowlifes not even worth a minimum of
care and respect.  Not a good thing to say to 2000 people when asking them
for a favor.)

* The lines for the nets from pins 5 and 7 of IC1 cut right accross the
symbol of IC1.

* The line from pin 4 of IC3 cuts right accross the symbol of the crystal.

* Much of the text around the crystal and its two caps is unreadable because
it's all jammed together.

* The labels around the switches on port B are such a mess that none of it
is readable.

* Many symbols were apparently rotated from their original definition, but
no attempt was made to re-orient the text to make it more easily readable.

There's more, but I don't feel like enumerating it all.

4  -  There is no description of what the circuit is supposed to do, making
it rather difficult to determine whether it successfully does it.

Which resistor?  I see 4.  Of those R3 is connected to nothing and R4
connected to some mystery device labeled just "trigger".

What transistor?  There isn't a single transistor shown on this schematic.

Perhaps after you've shown some care and respect.
