I started a thread a while ago, but the thread is old and the system won't let me post to it now. Plus I have a different setup in mind, so starting a new thread.
Disclaimer: I'm a Computer Science guy with only basic understanding of electronics, so would appreicate detailed replies (THanks!)
Problem: My PC case has a power LED, which is really bright and when I put the system in standby, it starts blinking - which is very annoying when I'm trying to sleep. What I want is a small circuit (with no external power because system is in standby), that is essentially self-driven in everyway. I will attach it to the power LED wires and also replace the power LED with either two LEDs or a bi-color LED. So that when the output is continous (system is on), green LED will light up, however, when the system goes into standby - the input signal will be blinking then the circuit should turn on (blinking is fine as well) the orange LED.
