How to make vibrating alarm clock underwear

randofo says: "The Goodmorning Underwear are a pair of panties that vibrate to wake you up in the morning. This project is a continuation of my ongoing efforts to further the field of electronic underwear… This particular project came about because I finally wanted to make a garment that my girlfriend would actually want to wear. While it may be hard to believe, when I made the Clap Off Bra it was not really for her."
