Week 10 | Open Source Hardware - From Fibers to Fabric¶

Insipration¶

This week's focus got my industrial design jucies flowing. I have always looked for way to mechanise processes and challenge the idea of who the "maker" is; the designer or machine? I also look to mechanise processes for efficency of time and use of materials. A big part in my fascination of how things are made comes from the processes and machines involved. And so a lot of the time I will get caught up in tyring to understand how a machine works in a certain process of making something and how it can be used for another function or tweaked to have other outcomes.

Siren Elise Wilhelmsen¶

Siren Elise Wilhelmsen is a deisgner that seeks ways to stimulate ideas and discussions around our everyday objects, rituals and culture. My favorite work of her's is 365 KNITTING CLOCK wall-hanging clock that gives a physical representation to time passing more then just numbers on a clock face, but with the past having been knit and the future still wound in a spool. This article has additional information and visual documentation to her project.

Will Cruickshank¶

Will Cruickshank is a multidisciplinary creative whose practice includes sculpture, film, photography, and printmaking. His recent work has focused on making objects through the development of experimental machinery, materials, and production methods. He has been repurposing equipment such as cement mixers, bikes, or potters wheels to develop complex makeshift weaving machines, improvised lathes, printing presses, and water carving techniques and tools. Below is a video compliation he made of his machinery development stages in Methods 2016-2020:

Jen Keane¶

Jen Keane is a designer, material inovator, inventor of the microbial weaving prcoess and founder of Modern Synthesis. Jen's most notable project is This is Grown that merges modern, mass-production textile practices with a philosophy of future biotech and enhances a new form of ‘microbial weaving’, the growing process of k. rhaeticus bacteria is optimized to weave a hybrid material that is not only strong but also lightweight. This articel on designboom.com has a great insight into Jen's mission and process of her This is Grown project. Additionally on her Instagram she shares beautiful visual documentaion of her projects.

Past Work¶

Back in the spring of 2019 I missed my chance at taking a weaving class at Mass Art and instead took it apon myself to make my own table loom to self teach the principles of weaving:

Rigid Heddle Loom Fix¶

At the textile center here in Blönduós I came across a rigid heddle loom with a broken heddle that needed to be replaced. The rigid heddle had been made out of plastic and had broken eyelets that would a nightmare to weave with.

And so I took inspiration from Ashford's Veri Dent Reeds to design a new rigid heddle for the table loom.

I first designed 2 different dent sizes and then how the parts would be assembled. I had in mind that one could slide in the different parts on to the rigid heddle and make it modular. However, after assembling it all together I realized that a better design would be to use wing nuts to sandwich the top and bottom bars around the dent pieces. Rather then relazer cutting everything, I will drill holes into the pieces and find wing nuts to secure it all in place. Below are the files and images of the first attempt at making the modular rigid heddle.

Materials

4mm Plywood
Laser Cutter
Wood Glue
4 Bolts and Wing Nuts

Files:
- Small Dent File
- Large Dent File
- Top Bar File
- Bottom Bar File
NOTE: Different colors are assigned in the files so they cut in a ceratin order. Configure laser cut machine to process colors in files from blue to black to red in order to have the detailed parts cut out properly.

    Laser Cut Settings:
    Speed: 15
    Power: 100
    Frequency: 10

Incubator¶

For our group project we collaborated on making an Incubator for the studio. We divided the team into 3ish steps. I took on laser cutting out the exterior box, sliding door, and shelves. Birdy and Margrét took on building the insullation layer and with the help of Louise programed the Arduino.

Below is the documentaion of our process and notes:
