That's the entire purpose of the [OT] prefix - you can SKIP those if
you only want to stay completely on topic.
Though - IMHO - a reminder to *keep your eyesight safe*, is not
necessarily off topic for this or any other mailing list, is it!?
Complain if someone forgets the [OT] prefix, maybe. Not necessarily
to the whole list.

This thread is FAR from being zero information, it DOES have a VERY
valid point on the subject of safety. It is far too easy to just dive into a
box of tricks (PIC based or otherwise) with little more protection than a
data sheet draped over the offending kit.
Like many of you I have been on the receiving end of a stressed electro
(and PICs) and THEY REALLY CAN HURT. I have a number of PICs
embeded in the Lab walls from work on 'live floating' applications like
power line control, and I know the subject of 'live power supplies' has
been covered on this list.
SO KEEP SAFE and keep PICing.

I'm lucky (sort of) in that I wear glasses all the time, and for years have
selected oversize lenses for exactly this reason. Every once in a while
I'll get a cut lead bouncing off them, or in one case, a chip from a
grinding wheel (I wasn't even the one USING it!) I'll still use goggles if
I'm deliberately working on something nasty, but it's nice to have that
layer of protection all the time.
Most people wouldn't think about it, but if you REALLY hate the look of
those standard safety glasses (my sister calls them "birth control
glasses") then you can go to an optical shop and get any frame you want
done with zero prescription lenses, and even photogray and anti-reflective
coating. One reason that people don't want to wear those awful things is
that their fit is horrible, and the inter-occular distance is usually
wrong. Imagine if they had safety boots, but only in one size.

10 Commandments for Technicians
I. Beware the lightning that lurketh in the undischarged
capacitor, lest it cause thee to bounce upon thy buttocks
in a most un-technician-like manner.
II. Cause thou the switch that supplieth large quantities
of juice to be opened and thusly tagged, that thy days in
this earthly veil of tears may be long.
III. Prove to thyself that all circuits that radiateth and
upon which thou workest are grounded and thusly tagged,
lest they lift thee up to radio frequency potential and
causeth thee also to make like a radiator.
IV. Tarry not amongst those fools who engageth in
intentional shocks for they are surely non-believers and
are not long for this world.
V. Take care that thou useth the proper method when thou
takest the measure of a high voltage circuit, lest thou
incinerate both thyself and thy meter, for verily, though
thou hast no account number and canst be easily surveyed,
thy test meter doth have one and, as a consequence, bringeth
much woe unto the supply depot.
VI. Take care that thou tampereth not with safety devices
and interlocks, lest thou incurreth the wrath of thy
instructor and bringeth the fury of thy instructor upon
VII. Work thou not with energized equipment, for if thou
dost, thy fellow students will surely buy beers for thy
spouse, who liveth, (and consoleth them in other ways).
VIII. Trifle thou not with radioactive tubes and
substances, lest thou commence to glow in the dark like a
lightning bug and thy spouse have no further use fo thee
except thy wages.
IX. Causeth thou not to make unauthorized modifications
to equipment, lest thou arrange to have recorded all
field changes and authorized mods made by thee, that thy
successor shall not tear his hair and go slowly mad in his
attempt to decide what manner of cretin hath made such a
mess in the wiring of such equipment.
X. Be thou cautious in the placing of thy digits into
such equipment that would cause thee to sorely lament the
loss of thy greatest sexual appendage.
