Time-nutters-- I have had several instances where I needed to monitor the continuous presence of pulses too short or too spaced out to check on conveniently, even with a scope.
My solution was a one-shot monostable IC driving an LED. Example--: a uS (or whatever length) pulse triggers the one-shot which turns the LED on brightly for 1/10 second. I have incorporated this feature into several PC board projects over the years. I am anally-compulsive about installing ways to monitor different functions in the circuitry of my projects. On a couple of occasions I have gone so far as to build a sub-panel with a collection of monitoring indicators. These have been huge time savers for quickly zeroing-in on the cause of many problems occurring long after I have forgotten the working details of a projects circuitry.
