Small, Medium, and Large gears connected

These are our studies of the full model and our gears. The gears will be placed on a plate just under the top plate (that will hold the paper) of the box-part of the study model. They will be turned by a crank attached to a vertical gear that connects to the rest of the horizontal gears. Each gear has at least one half inch hole in it where a magnet can be placed. The gears will be made out of dark wood and cut out on the lasercamm. The final box will be made out of light wood, and the arms will be made out of dark wood. The squares on the top of the study model represent two plexiglass pieces that will dispense charcoal onto the paper below. One of the plexiglass pieces will have cups filled with charcoal and iron shavings and the bottom will have holes, so when that bottom one is pulled away, the charcoal will fall onto the paper. The magnets placed in the gears will pull the charcoal and iron shavings as they turn, thus creating a drawing.

Marble Machine Sketches

This is a sketch of our marble machine. The user will turn a crank which will send the marble up the stairs as they rise and fall into the ink container. The marble will then land on a double pivoting table and create marks on paper.

The Pendulum Takes Shape

 A rough sketch of what the final design will look like.  A pendulum swings in the center of three cable-stayed legs.  The drawing is made when the paper moves under an inkwell.

A sketch of the pendulum bob.  This will hold the paper as it swings below the inkwell.  Three metal-lined holes will attach to cables , which will be suspended from a ball joint.
