[time-nuts] Divide by 3

[Mark Sims]

When I was working on the temperature control feature of Lady Heather,  I noticed that I could detect when ever I opened the refrigerator door (in the next room) or when I was in the same room as the Tbolt by looking at the EFC or temperature sensor plots...  the Thunderbolt oscillator makes a nice thermometer.  People are basically a 100 watt space heater.

Another time I was working on a precision temperature recorder (based upon an Analog Devices V/F chip).  It could easily detect when a person walked into or left a (rather large) lab.  You could even quantify the number of people in the lab (one particularly large guy counted as two people).
