I think it is time to upgrade the technology I have used for 14 years to monitor the temperature of my compost pile.
The graph below is live, as long as I keep going out and reading the temperature and coming back in and updating the Google spreadsheet. In 1998 I inherited the old YSI thermometer device and found a 7.5 volt mercury battery for it. The battery is still good, and I even have a spare (also 14 years old). I hope that the participants at LEAFFEST can help me find a replacement technology for the beast.
The featured pile was built on September 10 from a three month accumulation of kitchen, garden, and yard waste, some old hay mulch, freshly cut alfalfa, 100 chopped corn plants, a quart of organic fertilizer (5-3-4), and 20 gallons of spent tomatoes, cucumbers, peppers and cabbage. The pile was turned on October 7.
