For the past few days, I've been thinking over and over about an electronic device that could hibernate. One thing that strikes me here is the very fast pace at which weather and illumination change throughout the year. At this time of the year, daylength is about 14 hours. It will drop by 5 minutes every day until it reaches about only 5 hours by mid-december...
At that time, temperature will go down to -30 °C and even lower, according to locals. The lowest recorded temperature was -55.8 (February 11, 1979). Given these conditions, combined with the inhabitants' reputation as being heavy drinkers, it is not a big surprise to learn that people often lose toes due to frostbites around here. It has even given to a local, absolutely disgusting attraction, involving "drinking" a real human toe.
Anyway, coming back to the subject at scope, I thought it could be interesting to think about how an electronic device could survive through winter. I started with the idea of using a "pole" (like, a PVC tube would be perfect) part of which would be under the ground, to help for insulation against the cold. I thought about several ideas, I'm still hesitating between using sound, light, or both. Soundwise, I'd like to have the device emit a "whistling" sound from under the earth, there's kind of a creepy feeling to that, I like that. I also like the idea of using LEDs, maybe somehow mimicking the Northern lights. I like this mood lamp among other things.
After a lot of thinking and a long chat exchange on the AVR Freaks IRC channel, I came up with a few notes and strategies.
