    If you have an old PCB and it's heading for the bin.. then STOP !!

    The more components it has, the better. Just hold it horizontal, and up at
    eye level.. about 6 inches fromyour eyes.

    Hey Presto.. your very own miniature spage age city.

    How the hours fly by.

    Does anyone else have ingenious uses for old bits n bobs?

    They've ALL done it, they just won't admit it.

    Yes I do.

    The underside of a PCB makes for a very good surface to rub down the
    corns and bunions on my feet.

    Also, putting mains voltage across some of the components (especially
    the electolytic capacitors) and you have your very own indoor fire-works
    display! (Dont try this at home kids...)

    Fans, such as those used in microwaves make very good egg-whisks.

    Constantin wire, used in wire-wound resistors (usually high wattage
    types) can be used to make snares to catch furry animals such as rabbits
    and squirrels in your local woods. The advantage is that as well as
    trapping these animals, you can eat them as well.

    Old LEDs can be used to make kids jewelery. Cut off the legs, drill a
    small hole (1mm) through the base and thread the 'beads', preferably
    with a bit of constantin wire (see above). Be careful that the little
    ones don't take the new choker you have created too literally....

    Coils such as those from mains powered motors make useful corporal
    punishment tools (though this may be illegal in some areas). Just ensure
    the victim, I mean subject, is connected to the terminals, then using a
    9v battery quickly connect and disconnect the battery across these
    terminals. Shocking.

    I have many more uses for scrap electronics, but due to the size limit
    on these posts I am unable to.
