newbees keep on asking questions......

Hi all "Bees"

You are in a danger zone...

"Tom's Cookbook" is an assortment of things that Tom has built... not projects
for people to copy (easily). If you wany easy, I'd order a PCB from him, they
are
reasonably priced, and have been built by many. Problems are pretty well
documented.

The "Cookbook" has schematics that are right from the breadboard
(Pooh!  solderless breadboard... AND BBD's!!!)

So some of them may be lacking a component here and there when they were drawn.
Some one like me "reasonably skilled in the art" does not even notice that they
are missing. I automatically fix such omissions... like the power supply pins on
the LM13700 in the VCO5 cookbook recipe...  I worked with a guy on the VCO4 for
about a week,
and finally tracked it down to a schematic error... on a jack. I had built two
of them... and
looked at the error, realized that it was shown backwards, and built it
correctly. Then forgot that there ever was an error...

I think that Tom has disclaimed the cookbook as far as "support" goes. (correct
me if I'm
wrong).  I'm happy to offer assistance if I can, on cookbook or anybody's
schematic as
long as I can see it.

This is how I learned. My dad would answer "three questions" a night... then I
had to leave him in peace to watch TV.   I'll offer the newbees the same.  This
forces two things..
1) Effort to grind through the problems yourself... best learning experience
2) Thinking... what 3 questions should I ask here ???

The main thing you need is perseverence !! Take a schematic and beat it until it
submits...
or until you learn WHY it was not such a good design after all.  Don't just wire
and expect it to work... it never does. Not for me... not for you.  Only
difference is I DO NOT LET
THOSE FVCKING LITTLE ELECTRONS PUSH ME AROUND !!!

If you don't want to stick with things... then save your money and buy a kit or
complete
product. You're wasting your time.  I think DIY is good to learn from, to get
something
that you cannot buy cheaper...and the satisfaction of conquest over something
that you
outweigh by a factor of 1000 ???

Was that filter that oscillated like crazy one of the MS-20 types ???    ;^)
