Big Mess o’ Wires backcountry logger: [via]
If you’re just tuning in, the backcountry logger concept is a portable ATmega-powered device that collects temperature, air pressure, and altitude data, and shows graphs on a built-in LCD screen. It’s intended for hikers, climbers, and other outdoorsy folks who want to know if it was colder last night than three nights ago, whether the ridge they’re on is the 10200′ or 10600′ one from the map, or whether a storm is likely soon. Much attention has been giving to minimizing power consumption, so the battery should last many months.
