   Many of the computers I work on (i.e. repair) have fans
on the CPU chips and elsewhere which include a pulse
generator.  These are mainly Hall-effect sensors and are
monitored by a circuit that looks at the pulse frequency to
measure fan RPM.  

   It would be nice to have a box that would support
multiple such circuits and turn on appropriate warnings when
the RPM of a device fell below a set parameter - plus offer
signal outputs for use by other devices, such as an EM.  

   (Sorry, I can *fix* circuits, but I don't make them.  I
*make* chips/shavings.)
