In this project, each student builds the following
circuit on a prototype board:

The completed circuit is shown in Figure 2.
The three connections shown in black are those that the student
is to find on his own. The other connections are given in the
Student Guide.

In Part 3, the student is required to generate
a nominal design graph on 4 cycle loglog paper which is provided.
The final graph is shown in Figure 3.
It is important that, in the competition to
be held at the end of the project, enough assistants are available
to measure the time intervals and supervise the activity. One
assistant should keep track of the three current best times.
In the first running of this project, the three prizes were $25, $10, and $5 gift certificates to the University Bookstore.
