The Problem.

As part of the subject ‘Product and Form’ the students had to complete a series of 3 projects. The biggest project was the mechanical timer. This timer needed to repeatedly measure a time of at least 10 seconds. Electric circuits where forbidden so rewinding needed to be done manually.

The Process.

The teachers warned us that most of the mechanical timer systems were already made and it would not be easy to create a total new mechanism. However, just copying an existing system was not permitted eighter. I chose to change an existing system so that it would not be recognized as such or even as a timer. Three exactly the same, Coca Cola-cup looking objects were the made solution.

The Result.

Inside the cup, or tube, is a small weight connected to the stroke by a wire. When the stroke is rotated the weight comes to the top. After positioning the other two strokes very carefully the rewinded stroke can be released and it would start rotating in the opposite direction. As a result of the g-force on the little-weight on the outer side of the stroke, The wire would rotate a few times on the 2 other strokes creating the needed delay.
