Bruce Field and daughter Ellie are happy campers, thanks to a portable heating/cooling device they built that maintains a constant, comfortable temperature inside their camping tent. To ensure complete climate control, they equipped a standard room air-conditioner with an electrostatic air filter, economical slinky-type dryer ducting (that minimizes number of holes cut into tent fabric), and a constant-temperature feedback sensor. An optional motion sensor discourages both curious neighbors and hungry bears.
