H.D.D. Bicolour Activity Indicator

@ 2004/06/25
Tired of seeing that HDD LED always shining? It's kind of bland so I decided to do something with more eye candy. I saw circuits in some other sites that used two LEDs, but I wanted to use a single bicolour LED that would change its colour depending on HDD activity. I also wanted to be able to represent both information using a single LED. The circuit is very easy and cheap to do, it doesn't require too much soldering, so any person with basic knowledge is going to be able to do it without any trouble
