Re: Slighty zapped from metal casing - DO NOT WEAR GROUND STRAPS

More properly, the typical wrist grounding strap has a 1 Meg resistor in
series with it.  Sufficiently high to prevent shocks with "reasonable"
voltages, sufficiently low to bleed of electrostatic charge.  However, above
100V or so, even a meg is too small.
