[sdiy] Monitoring my Dotcom system's supply voltages

[Jean-Pierre Desrochers]

I'm about to design some kind of circuit that will monitor 
my 3 power supply voltages which are +15v, +5v, -15v.
Each voltage will have a LED that will be on as far as
its voltage is in an 'acceptable' range.
Ex:
+15v rail: +14.9v and more is Ok.
+5v rail: +4.9v and more is Ok.
-15v rail: -14.9v and less is Ok.

So far I browsed the DIY forum without finding any talks on that..
I'm sure there are ready to use schematics on the DIY community
and I am asking before I go to the design process..

Thanks for any findings !
