[sdiy] Spice....

[harrybissell]

hmmm... I bet you can figure it out.

Spice is a really GOOD tool for the experienced designer.  Its a lot
easier to
do 'what if' kinds of analysis that it is on a (non solderless)
breadboard  :^P

You can also use it on a laptop, hence on the road... stuck in a hotel
with no
synths, you can still DIY !

It will NOT tell newbies when they are being dumb.  I did a clamp
circuit in Spice
that seemed to work perfectly. Then I said to myself "Self..."  it looks
like the upper
clamp is going to feed the lower clamp... with no limiting impedance.
Wonder what
the current is...

...well it turns out that Spice would tell me that... it was about three
hundred AMPS.
This from a 741 running at +/-15V.   Is it any wonder that the couple of
mA signal got
clamped VERY well ???   And the computer did not even get hot, no smoke
came out
and the lights didn't go out either...

I suppose that my stance on spice makes the the bastard love child of
Bob Pease and
Barrie Gilbert   :^P
