Add style to your HDD led with this simple circuit. Time to do some modding again. Like in most of my mods, the idea is to keep the costs down and not to make the mod too complex to put together. What I have heard from our reader feedback, this is the way to get new people to get interested about the modding scene. Sure we all love to see all those full scale modding projects that can take hundreds of hours but in many cases it all comes down to adding this kind of small details together. Learning to make these will get you started with that mega project in no time. :)
