I am wondering if hooking a couple of diodes (1n914?) will give me DC voltage, followed by a voltage regulator (7405?7805?). any body have a link or circuit sketch? I'd like to try to run a cpu fan with it- they typically take around 3volt. This big case fan is a 4watt, the cpu fans are 1watt. Does anybody know how to figure the amperage coming out of the casefan/genny??
