Project Calliope, despite involving the launch of a satellite into the ionosphere, is pretty basic. The project's goal is to use a tiny satellite equipped with a radio to convert atmospheric measurements into music to be enjoyed back on earth.
The little thing just needs a radio strong enough of pulling that off. The project's Kickstarter is most of the way there, and the creator seems like a swell enough guy, so if you enjoy space, music, or small satellites, maybe throw him some change. [Project Calliope]
