No, most of the replies were from people worried
that you may fry yourself from the power source
you are trying to control with a Triac or SCR being
run off the parallel port of your computer.
However much you may know, so far you have *shown*
no understanding that the low current, nominally 5v
TTL level out of the parallel port and the (presumably)
nominally 120v, at least 10A (and probably more like
15 to 20A continuous without tripping any breakers,
with peak current levels prior to breaker trippage being
MUCH higher) levels available from whatever wall
socket you are probably tapping into are as different
as night and day.
You may understand this, but it sure doesn't seem that
way from your posts.
When you *sound* like the guy who asks "what happens
when I stick the screwdriver into the electrical socket
while leaning across the kitchen sink" you had better expect
people to sound off with a "Whoa".
If you want people to take your questions seriously,
phrase them so it sounds like you know enough to
avoid self-electrocution. There are some people
who just don't know which end of a soldering to
pick up. If you come across sounding like one, you
will be treated as one.
