Now how do we solder up this Triac circuit with a dead Soldering Iron !!

Yukio YANO

Seriously, Do you use the original cord ?, I can't visualize how you could
do that without compromising the green grounding lead , As I recall, there
are only three wires in the factory Cable, and three pins in the connector!.

I did use the original cord, and as far as I remember I kept the barrel of
the pencil at ground potential. It is quite while back now but I remember
having some anxieties over grounding issues. I must have resolved them to my
satisfaction, so I am fairly sure this design group can do a similar or
better job. The station and pencil are quite a few thousand clicks away, and
I am not quite done with my holiday yet. It seems as though you may have to
re-visit that problem.

I did make an ass of myself when I came to wire my creation together and
reached for the soldering iron. oops!!!


Added:-
From the dregs of my shaky old memory I recall a 680R for the trigger and a
daisy chain of 3 x 33K for the ground link.

I just love the mental picture of having yiur soldering iron apart
and needing to solder a connection inside of it. Sort of like
soldering 32 XLR connectors to the end of an audio snake and then
realizing that you didn't slip the parrels over the wires first.

or trying to fault-find your (only) oscilloscope. The first tool you reach for
(after the screwdriver) is ... your oscilloscope.

Yeah, but at least you could solder! ;-)

Cheers!

Bah. Back in my day we fixed our soldering irons by using 220V and two
wires to arc the solder joint. And when our oscopes went out we used
our tongues as current meters to get 'em fixed. You knew the frequency
by how deep the tingle was.

And gol'darnit, we liked it that way.
