First test with valley, no calibration. Position 4.

Experimenting with different positions. First 2 are “push-tap”.

Bracing for pen to stay upright was produced after. We though pen would stay upright from the tensions of the rubber bands around 4 sides.

img_5297 img_1805img_1806

The final version was an adapted pen holder, with rubber bands tied back to bolts that screwed into frame.

After making a rigid pen holder we laser cut a simple spirograph arm and made a rigid base.

We then hung the pen from the middle of the clamp with a wright attached as a second pendulum.

This is a project we referenced to find the dimensions for the spirograph arm

This is the table we built to attach the drawing arm. We initially laser cut the arm out of chip board, and eventually laser cut it out of 1/8 inch ply wood.

This image is our first attempt of holding our hand still while the base moved back and forth.

We tried making a base which would aid in containing the twine to the beam. We were short by a fractions of an inch and abandoned this idea. Instead we used a 2′ clamp and wrapped the twine directly on it.

Drilling hole into base to tie twine.

This base method was too restricting and required extensive calibration. So we turned to suspending the base from a beam and working with the arm as a main part of the drawing machine.

This is the first sketch attempt at creating a frame with a pen attachment that would engage with the swinging drawing base.

laser-filetest

This is the test file for the base of our crank. Top is to be a pendulum that draws according the the base plate’s movement. Fork that attaches the ball joint to base plate is not in this image of the laser cut file. It is forked in order to allow for the crank to rotate.

hulq_pit_pendulum

The top of the machine would be a pendulum that moves along the base plate.

This raindrop crank could be used to move base of drawing plate.
