[Hidden-tech] low tech or high tech?

[ussailis at shaysnet.com]

Tom,

If that ever happens again (let's hope not!) here is a little known hint
about electronic circuits.

After soldering, many of them are washed...in water. Of course
de-mineralized, clean, hot water is used. Northampton and Quabbin water
qualifies, but the water at my son's place in Ashfield probably does not.
Too high a copper content.

I wash the circuits that I build with an old toothbrush and hot 'Hamp tap
water. Works just fine.

Jim,
hah...good one.  i'm all for down-home solutions... i love duct tape too...

one correction: an ipod does play mp3 files...it's default file is an mp4 or
AAC file...but, the generic term 'mp3 player' can be used when talking bout
ipods...

and i know what you mean about putting all your eggs into one basket...the
pouch holding my  ipod, palm pilot and cell phone fell into the um, well,
toilet...about 6 months ago...miraculously after about 2 days of drying out,
everything was working just fine...

Not sure what the moral of the story is here... but it's nice to share such
things, i guess...
