Electromagnetic bracelets for building PC?

    I once read somewhere that when dealing with the innards of electronics
    (including computers) it's good to wear special electromagnetic (or
    something like that) bracelets that way you don't damage the equipment. I
    think I've seen these at Radio Shack. Would it be wise to pick up a pair or
    is it just a gimmick?

    I have one in my kit. I use it whan;
    - I'm working with really expensive, or non-comodity parts that would be
    a real PITA to replace,
    - Working on a business server where downtime would be a complete f**kup.
    If there's a mystery electronic problem afterwords it's something you
    should/could have done. Not that the strap, itself, would have
    prevented the failure but it might have. Call it CYA, and I'm a firm
    believer in Murphy, and his laws.
    - There are places and times where that static is everywhere. You can't take
    two steps and touch metal without getting a spark.

    The static voltage sufficient to blow an unprotected chip is well below
    the voltage that is perceptable to you, I'm told.

    In general, I just touch the case before I handle the part and keep
    one body part on the case for the duration. The textbooks will tell you
    that this is nowhere sufficient.

    I once read somewhere that when dealing with the innards of electronics
    I am not sure what you saw but there are wrist straps that help. It is a
    conductive strap that goes around your wrist and it has a high value
    resistance going to a wire that connects to something that is grounded. It
    can be connected to the ground of a 120 volt receptical if you are sure to
    get on the correct pin and are also sure that pin is grounded. Many never
    use that strap and have no problems, but it it highly recommended by most
    makers of devices of electronics . Some moth4erboards I have bought have
    cane with them. I work on industrial instrumentation and some of the
    instruments come with the straps also.
    In high humidity it is not that bad but in the winter time and low humidity
    you can build up a static charge quickly. HOw many times have you gotten
    shocked in the winter ?]

    The anti-electrostatic bracelets do help prevent you from accidentally
    frying a component with a static discharge.

    Not a gimmick. It helps drain the electrons from your body while
    working with sensitive electronic parts. Very important when handling
    video memory. If you don't have a strap, keep one hand on the metal
    case. I like the kind with a coiled cord and velcro strap.

    Mix a tiny amount of fabric softner with water and spray around the
    work area, mainly the carpet. They have a new cordless wrist strap out
    that I have my eye on. http://www.directron.com/directron/1160125.html
