Grant Meacham has designed and built "The Barbie Box," an mp3 player case which is doubles as a boombox, converts to a quarter-inch headphone jack, and camouflages itself as an early-nineties tape player. Want more? Well, when paired with thirty-year-old aviator headphones, this rig will make you the farthest thing from a white earbud target.
It's a portable music player on your way to your studio or office, and then on arrival--with a flip of the switc--it becomes your desktop stereo (the speakers are built in).
And the best part? Meacham has posted the instructions for making your own at core77 fave instructables. Don't know how to solder? Contact the designer at www.grantmeacham.com and see if he can bust one out for you.
