10. Open Source Hardware - From Fibers to Fabric¶

This week we visited Kniterate, a knitting machine company based in Barcelona and learned all about how knitwear has evolved with knitting machines. We also visited L'Originaria an upcycling company

Then we had to create our own machine that would be used in our local labs. We were provided a list of projects that could be used as a reference to build a specific design. I worked with Grecia to create a microscope.

Refrences & Inspiration¶

We checked out the example of the Microscope with a web camera project to understand our task.

Research¶

Microscope: an instrument that produces enlarged images of small objects, allowing the observer to see the details of an object scale that for examination and analysis.

The word “microscope” comes from the Latin “microscopium,” which is derived from the Greek words “mikros,” meaning “small,” and “skopein,” meaning “to look at.” The development of the microscope allowed scientists to make new insights into the body and disease.

It’s not clear who invented the first microscope, but the Dutch spectacle maker Zacharias Janssen (b.1585) is credited with making one of the earliest compound microscopes (ones that used two lenses) around 1600. The earliest microscopes could magnify an object up to 20 or 30 times its normal size.

Compound microscope designed by Robert Hooke, 1671–1700, and thought to have been made by Christopher Cock of Covent Garden, London.

DIY Microscope Design¶

Rough sketches

3D Printed Camera Holder¶

The printing was done with PLA filament and at a layer height of 0.28, which gave us 2 hours of printing.

3D printing with resin-Grecia¶

For the resin, the standard one was used, it took approximately 6 hours and the curing time with ultraviolet light was 12 minutes. The imoresion quality was excellent, the screw mechanism was printed very well.

We had to change the 3d printed camera holder to fit with the cables

ELECTRONIC Connection¶

It is important to review the datasheet of each board with a camera since the pins change, there are models similar to this esp32, the only difference is that they have a microphone.

The components were then welded and secured to the structure.
