I found this circuit for making a HDD indicator LED's for putting into your keyboard. I bet someone will put it somewhere other than the keyboard. So I thought that just maybe someone at Modders-Inc. would like to give it a try. Here is the link for the circuit. http://metku.net/index.html?path=mods/vilkkuvalot2/index_eng
Good Luck and have some fun with magic lights. Happy Modding to ya.
