Scientists use iPods, car batteries to build a frog surveillance net | Ars Technica: " Arbimon (Automated Remote Biodiversity Monitoring Network), was created by a team led by Dr. Mitchel Aide and Dr. Carlos Corrada-Bravo of the University of Puerto Rico. As described in a paper published by the team in PeerJ today, Arbimon's monitoring stations use an iPod recording application to capture up to 144 one-minute audio recordings per day of animal calls. Most of the components of the monitoring stations—the iPod, the battery, a voltage converter, a preamplifier for the microphone, and a router—are in a sealed watertight case. A 50-watt solar panel powers the system and charges the battery during the day."
