Attempted to do one of these and afraid i am in over my head. I got the project box from radio shack, the fan, and a fan controller. My problem is the first cell phone charger i got didnt work. I dont know whether is the charger itself or not. I dont know whether i am attaching it tot the rught wires on the fan controller or not I got a blackberry charger and plugged it in and both wires are hot. Can i send the pics to someone for help please? Thanks.
