1. To go; to walk; specifically, to move with regular or
2. To walk up and down nervously, as to expend nervous energy.
These are instructions for building a home monitoring system that measures and documents nervous pacing activity. The result is a physical visualization of the amount of pacing, for personal use in a domestic environment. The purpose is to visualize the distance traversed while engaged in measured, contemplative walking.
The monitoring system takes the form of a track, specifically scaled and designed for pacing on. The track is elevated from the ground level and balances on a subtle see-saw. Sensors at each end of the track keep tabs on the amount of laps. The distance paced is calculated and transmitted to a wall-mounted unit which dispenses an equivalent length of red yarn. The yard accumulates on the floor, anywhere you choose to install it. Mine is installed by the doorway.
1. You have a basic understanding of construction and fabrication techniques,
as well as access to the appropriate tools and facilities.
2. You have a working knowledge of physical computing (reading circuit diagrams)
3. You are overwhelmed with the anxiety of living in a failing state, and frustrated
that most of your household objects address only physical rather than emotional health.
