Last week, DARPA's HTV-2 (Hypersonic Technology Vehicle 2) Falcon vehicle launched to near-orbital speeds aboard a Minotaur rocket before beginning what was designed to be a Mach 20 glide back to earth, demonstrating the kind of hypersonic capability needed to deliver a payload anywhere in the world in an hour. Then, a few minutes into its flight, HTV-2's data transmitters went silent and so did the DARPA news stream feeding us the play-by-play.

"Why won't they just shut up about (insert your least favorite abusive sitcom star, diminutive bepoofed reality star, brain-dead politician, or Kyle Sandilands here). The talking heads may never shut up, but that doesn't mean you have to listen to them--and some enterprising Makers created an Arduino-controlled gadget that'll make that even easier.
