Fab Academy week 12: sticky textiles making strong composites

We enjoy the Composites week because it requires a  very hands on and experimental approach.

Composites are materials resulting from 2 elements with different features. The Fab Academy students were asked to choose one compound with lots of strength and another with good flexibility features.

By mixing or laying them together you should acquire a composite material with the best characteristics from both. Epoxy resin and textiles are the perfect example: when layers of fabrics are impregnated with epoxy resin and vacuumed, the resulting material becomes an almost unbreakable surface.

How do you determine if the process was successful? Well, you beat the object on tables, floor, against walls, and see what happens. It should withstand your torture and not break.

The week started with our guru Ferdi designing a hot wire cutter for us, so that we could chop pieces of styrofoam for later machining our 3d design on the CNC. Some of us in need of better milling resolution worked with high-res foam.

The milled object is the mold onto which lots of other material substrates are laid. What sometimes happens is that the textile is unable to follow perfectly the shape, therefore students need to design darts to absorb the eccess of material in certain parts of the casting process. Jani is testing this process in the attempt of creating a baseball hat.

When the 3d object is milled, you get onto the funniest part of the task: spreading epoxy resin on the fabrics and covering everything in cling film and a breather layer to allow the excess material to be released during the vacuuming process.

Fab Academy weeks 10&11 : inputs and outputs

Things start getting interesting when you design and program your own microcontroller. The past weeks assignments focused on getting a better understanding of input and output possibilities for projects incorporating electronics.

Students tested a wide range of sensors and actuators, and programmed in C code, Arduino and Python. We are proud to share some of their successful tests. Looking forward to see how these initial prototypes turn into Final Projects!

N.E.RO. NETWORKING ENVIRONMENTAL ROBOTICS WORKSHOP // MAY 2015

N.E.RO. NETWORKING ENVIRONMENTAL ROBOTICS WORKSHOP AT BEYOND BUILDING BARCELONA FAIRE

The usage of drones has become a common practice today, with applications in several sectors, from leisure to professional services such security, photogrammetry, environmental mapping and tourism. N.E.RO. technology focus on data recollection translating different layers of environmental conditions into useful and accessible resources. During this event, we will explain all the fabrication processes of our one of the first versions of drone N.E.RO-01. This live presentation will give participants the opportunity to interact with drone technology, from mechanical frame design to electronic assembly.

REQUIREMENTS

No requirements are needed. All material needed will be provided by the organization.

AGENDA

Design: parametric drone design

Fabrication: laser cutting the frame

Electronics: assembly and fly test

REGISTRATION (until 15/5/2015)

TASKA

FOLD

Taska is the Icelandic word for a backpack and also a multifunctional bag made to carry everything from a laptop to all your camping gear. The design of the pattern is simple and the bag can be made from one single piece of almost any textile, which makes it easy to assemble. Eliminating weight-carrying seams gives it more durability and longer life expectancy. With any wood and textile Taska can be easily made in a local fabrication laboratory within the global network of FabLabs.

OPEN

For us the beauty of this project is not only the backpack itself but the ability of distributed manufacturing. In that way it is possible to eliminate long distance shipping, to use locally sourced materials anywhere and gives the customer a change for easy customization. A product that changes according to culture. Textiles and wood from all over the world take the form of Taska, embracing culture and local production

CULTURE

Taska can be fabricated with the following ways

1) Download the open source creative commons license design that comes with an instruction kit. With the materials of your selection, produce it at the local lab with the compromise of sending a short video of 1 minute of the making of and a picture of your version

2) Let the local fab lab to produce it for you with materials of your choice and pick it up.

3) Place an order from the designer.

Contribute to the growing network of Taska and make your version to reveal the multicultural world we live in.

Contact us to get or make your TASKA!

Designer: Ingi Freyr Gudjónsson

Making Things Talk Workshop // May 2015

Making Things Talk Workshop  at  BEYOND BUILDING BARCELONA FAIRE

On the past years we have seen us not using anymore the Internet exclusively from a table with a keyboard and a mouse to become a constant activity we do from bed to work, on the subway or in a bar, for work or leisure. For many of us the Internet is already present in our lives almost constantly, but how?
Although we have managed to have the Internet in our pocket we still use a screen and many times a keyboard like if we had a typewriter in our pocket. If we want to keep living like this, do we really want it this way?
This one-day workshop explores what happens when we explore the possibility of connecting any objects or space to the Internet, what we known as the Internet of Things.
This not only means thinking on objects, spaces and materials but to think the way we interact with them. The workshop will take an experimental approach, learning resources that allow us to quickly prototype our ideas and see how they behave. We will use of rapid prototyping tools that we all have available such as cardboard or our own phone and but also Arduino and Javascript.

REQUIREMENTS

Participants should bring their own laptops, Windows, Linux or IOS.

4-DAY BOOTCAMP // WIKIHOUSE

From April 14th to 17th, AA students participated in a 4-day bootcamp in Green Fab Lab to learn about the applications of digital fabrication in architecture. The workshop topic was to design and make a Wiki House version 4.

1

Students learned CAD / CAM for digital Fabrication ( Rhino CAM / Partworks), how to use of the CNC milling Machine (Shopbot PRS Alpha) and fabrication and assembling of the Wikihouse Version 4.

2

The Wiki House Pavillion will be exhibited at The Pavilion of Innovation, curated by IaaC | Fab Lab Barcelona, at the Beyond Building Barcelona – Construmat fair, next May 19th to 23rd 2015.
