Caution: Power Supplies!!

[Don Duval]

According to my professors in the ancient days of the early 1970's,  currents
of roughly 0.1 mA can kill by causing the heart to start fibrillating. Higher
currents kill by cooking. Shock hazards also vary with frequency.

To avoid the first method of electrocution, its a good idea to keep one hand
in a pocket while working on any energized circuit.
