By means of a cunning array of sensors and active
this normal-looking screwdriver tracks ambient
remaining neither hotter nor cooler than its surroundings.
In the event that this equilibrium is upset (for example, by
means of a warm hand; or by changing the temperature
the surroundings), the screwdriver will respond over a
of minutes to restore itself to ambient temperature.
To reduce power consumption, temperature adjustments
are made using an exponential asymptote model. This
ensures that the screwdriver rapidly equilibrates to within a
few degrees of ambient - sufficient for most purposes. If
higher accuracy is needed, the algorithm will continue to
fine-tune the screwdriver's temperature, matching ambient
to within an arbitrarily small error over sufficiently long
||If this were used as an improvised weapon, it would
increase it's temperature toward the temperature of the
victim. Nice feature, it's bad enough being stabbed, but cold
screwdriver just adds insult to an already serious injury.
||I thought this would be a screwdriver which would forever remain on the edge of your consciousness, pervasive, yet not obvious or intrusive, just evoking a general atmosphere of 'screwdriverness'.
||The best thing is that it uses absolutely no power.
||//it uses absolutely no power//
||Might be good on a cordless screwgun. Those things over heat when worked too hard. A miniaturized heat pump would be needed.
