Creating a Gear Box

Our first benchmark we had to build a single gear box that had the parent gear rotating twice as fast as the child gear.

Gear Box Cont.

Our next benchmark was to have our parent gear rotate in the same direction as the child gear. The left gear represents the parent gear and the gear farthest to the right is the child gear.

Laser Cut Your Name

We used a laser cutter to cut our names out of cardboard.

RGB LED

The arduino software was used to make the RGB LED show red, green, and blue.

Rotating Servo

The servo rotated rotated left and right at 180 degrees using Arduino coding.

Servo Box

For our moires, a servo box had to be made to fit around our servo. I recorded the dimensions of the servo and made the file in Inkscape to be cut out.

Laser Cut Pumpkin with LEDS

I laser cut a pumpkin head through Inkscape and coded two LEDS to flash yellow, orange, and red. The LEDS were connected by wire that plugged into pin 9, 10, and 11, and 5V in the arduino.

Moire Sketches

These are two sketches of two moires that I plan to make. There were a set of requirements that they had to follow: They have repetition at the same radial distance and they have repetition of form within each and together.

Two Servos & LED on One Arduino

One arduino was used to control two rotating servos and one LED. I wired the two servos together, then wired it to the arduino. For the LED, I plugged in two of the legs into pin 10 and 11 and the third one into GND. The servo wires were plugged into pin 9(white), 5V(red), and GND(black).

Moire Design on CAD

These are my moire design sketches that I created on Inkscape. One single shape was made then it was cloned around the center black circle. Afterwards, it was joined together by using the path: union tool to the black circle and the outer black circle.

Moire Design in Cardboard

I printed the file from Inkscape onto RetinaEngrave and it cut out the design on cardboard.

All Cardboard Pieces Cut Out

Using the files provided from the computer's hardrive made by my teacher, I cut the six files out on cardboard.

Independently Rotating Disks

This video shows two rotating disks on one shaft. The disks are rotating in opposite directions.

Final Kinetic Sculpture

Solidworks File

This file was used to show the overall setup of the kinetic sculpture. I used it to determine where the different parts went.

This is the code that I uploaded into the arduino that coded my LEDs and servos. I can refer back to this if needed.

Functional Cardboard Prototype

This is the final prototype which includes the cardboard moires and coded LEDs and servos. The lights show the colors purple, green, and cyan. This prototype was made possible through the various benchmarks above.

Presentation

20191212_082221 (1) (1).mp4

The purpose of this functional prototype was to give a representation of what the final prototype will look and function like. However, because the material that was used was cardboard, the functionality of the prototype had a few flaws. The cardboard gears were thinner towards the edge and therefor would gradually tear when in use but once they are cut using wood, it will no longer be an issue. To further improve the sculpture, I would need to make a few edits to the files that were used. When the servo mounts were cut out, they were not wide enough and I resorted to smushing it in order for it to fit over the servo. Also, there were too many holes that were to fit the LEDs on the middle acrylic file so if I were to not use all the holes for LEDs, they would be left vacant and that would be seen through the acrylic in the final. My moires are stable whenever they rotate but to ensure nothing breaks off when the material is changed to wood, I should increase the thickness towards the edge of the entire moire.
