I agree......................I only use it outdoors. A chemist friend of
mine once told me that if it get on your skin, it can diffuse into your body
and dissolve the fatty tissues, such as you liver, etc. The local Ace
hardware store discontinued that item because of the inherent dangers. I
think that about the only way you can buy it nowadays is through a company
such as Cope Plastics, and that would be by the quart, at the very minimum.
A very bad chemical, but the best thing that I have run into for fusing
plexiglass. Still, I wouldn't recommend it to anybody that didn't have
experience in handling this type of chemical.
As an aside, Methylene Chloride is one of the active ingredients in Zip
Strip, the paint and varnish stripper. Zip strip is handy for stripping the
photo resist from printed circuit boards.

adhesive is epoxy. There are better agents (Methylene Chloride), but
these
are very dangerous.

any

rectifier diodes, and bypass each leg of the power transformer's

Make
sure that you derate the 1uF units to at least twice the peak to peak
output
voltage of the transformer.
There is no such thing as a good wall wart, from Radio Shack or
anybody
else. Even the relatively expensive Power One frame supplies need
these
add-ons. The reason that these manufacturers don't do this in the
first
place is because they don't have to subject their units to stringent
EMC
testing.
I hope this helps.
Pete,
What is your preferred method for cutting the wall wart open?

Methylene Chloride is listed as a Poison. And is an inhalation hazard
that is heavier than air. It can KILL you.
Grundig has gotten in touch with me, we shall see what happens.
