Homemade Bluetooth hovercraft

OK, so the we posted the other day wasn't exactly popular with our readers, to put it mildly--"retarded" was one adjective we recall, among others. So we'll try again, this time with a Bluetooth-controlled hovercraft.

This seems like a lot of trouble to go through, especially given that this saucer doesn't even fly. But if you don't need the remote control, you can just go for the hovercraft alone--a challenge that we'd find daunting enough.
