Wi lead? From: Will

Wi I have some Sony in-ear headphones. The lead to one earpiece has
Wi been cut through completely and I want to rejoin the two wires
Wi (which I will call 'conductors' to avoid confusion).

Wi The two 'conductors' inside the lead are rather thin. And what is
Wi more, each of the two 'conductors' is made up of something like a
Wi dozen smaller copper wires which are woven around some very fine
Wi threads (perhaps the threads are very fine polyester yarn). The
Wi threads run along the lead as the core of the 'conductor'.

Wi The wires of one of these two 'conductors' looks like bare copper
Wi and is unoxidised so I can probably solder to it. But the OTHER
Wi CONDUCTOR is the PROBLEM because its fine wires are enamelled.

Wi How can I remove this enamel coating in order to be able to solder
Wi to the fine copper wires of the 'conductor'?


There is an enamel stripping liquid available in electronics supply
stores. I generally just run a hot tip over it to singe the enamel a
little then dip the end into paste flux. It usually works but if it
turns into a burnt mess I didn't do it right and start over.
There is also electric arc welding flux which is based on hydrochloric
acid. If this doesn't get the enamel off then nothing will! ;-)

OMG! Buy a new pair of headphones!

Valley Girls? More like IM freak. I was watching one young lady IMing
yesterday and it was pretty much shorthand for words, like u and b4 and
y not and etc. A really good way to ruin the english skills of the
younger generation.

On, I think, the Leno show the other night, they got a couple of IM
kiddies off the street, and two Morse Code operators that they'd hired,
and did a contest. They had two tables at opposite ends of the stage,
and they set a code guy and an IM kid at each table, and at one table
they had two identical messages, and the deal was, "Which is faster?"

Morse Code won. :-) :-) :-)

Well, after he's done screwing around with that horrid wire, the box
will be hanging around his chin anyway. ;-)
