I am moddin my art appreciation hard drive yet again for the same FU#@$ng class wich wont end soon enough....... And I have decided to extend the window/make a second to finish the design and add a pair of red 1.7volt LED's to it (internally) the drive doesn't work as far as usability goes but it does spin so i thought it would be kewl to add some color..... I need to find out either the formula on how to figure what resistors i need or maybe someone can fid out what ones i need and exactally how to achieve this mod.....( I am hopin to make everything do it's thing from the 12 volt power that it has always used ).......(the little four prong thingy to all of you newbies)..... Thanks
