This was one of the problems of the recent hackerrank contest (World CodeSprint 13). It had a really low success rate 18.5% which was shocking since this was one of the easiest problems in the…
I am inspired by nature, fractals, and diverse sustainable practices. I am also a gardener planning and preparing for my first growing season in the Midwest. All of my ideas for this project center around tools for the garden.
Idea 1: Biodegradable Seedling Pots & Trays
These pots and trays are made of cardboard to prevent root shock when transplanting. They easily decompose into the soil.
Idea 2: Hand Dibb(l)er
Dibblers or dibbers are pointed, generally wooden tools used for making holes in the ground for seeds. They come in a variety of designs.
Idea 3: Rolling/Bed/Infinite Dibb(l)er
These dibb(l)ers allow farmers to prepare large beds with perfectly even spacing for direct sow.
Idea 4: Tomato Trellis
Idea 5: Protective Netting
I chose my 5th idea to create a protective net for my plants because I love how easily it incorporates a simple and significant African fractal, and because it seemed well suited for creating with a laser cutter. Online I found a great demo video on creating golden spirals in Illustrator.
To make a golden spiral, I used the arc tool and transformed and distorted its scale, placement, and rotation, so that it fit perfectly together. I multiplied these spirals in both directions within a hexagon and made the shapes in between the paths my cut lines. Before being print ready, I had to use the shape tool to combine all my paths.
My first test print on a thin cotton at 15% power was very delicate and required 2 prints in order to cut all the way through the fabric. This image shows a small rectangular sample of the net pattern.
On my second attempt, I increased the dimensions of my file and printed on a thicker canvas material at 90% power.
Here are some images of my multiple attempts at creating the file in Adobe Illustrator. Unfortunately, both the cotton and canvas frayed into pieces.
After first attempts, I returned to SR Harris Fabrics and chose a green and white polyester that I hoped could withstand the delicate pattern. Using Rhino, I recreated the file at a larger scale, approximately 8" in diameter. Using the Offset and CurveBoolean commands, I created the thickness of each line and the shapes between all to be cut. After creating the first tile of logarithmic spirals, I copied and snapped them into place to print a larger iterative hexagon. Given the weight of the center of the design, I designed those lines to have even less weight.
After weeding the approximately 3'x3' piece, I experimented with presenting the work in a variety of ways: on the floor, hanging from the ceiling and wall, and as was my original intention–protecting a plant.
Going forward I will create an even larger net while ensuring that the net maintains more of its hexagon shape when hanging from the ceiling. Leaving a generous border around the 17 tiles will hopefully give it this structure and strength. This work will continue to grow as I prepare for an upcoming solo exhibition in January 2020.
