A number of decisions were made in Week Four.
Materials were discussed, as they would be purchased after the lab time. It was decided that the Lauan Plywood would not be used, as it was too thin. Instead, plywood of 1/4" thickness would be used.
The arduino was also revisited, to start looking into purchasing all components for that.
The sizing of the gears and spacing of the holes were also looked into. These are very important steps, as the mathematical accuracy of these measurements decide whether this toy functions or not.
After the lab time was over, some raw materials were purchased to fabricate the case. At Lowe's Home Improvement, two sheets of 1/4"x2'x2' oak plywood were purchased as well as two 0.08"x8"x10" clear acrylic sheets and two 3/8"x3/8"x36" square wooden dowels. In addition, a brad nailer was procured, since the plywood is too thin to be screwed into without splitting.
