Be careful with the supply, though. I did something stupid and used a 12v router supply. The regulator got hot (obviously) , so I put a coin on it to act as a bit of a heatsink. The coin slipped, crossed the Vin and Vout, and blew up my propeller! I had another one lying around, and all of the other components still seemed to work, but be careful!
I'm now using a 5v recycled cell phone charger.
If it's not broken, take it apart and fix it.
