Thermochromics + Heating Circuits

Pauline + Lindy

In this workshop you will be introduced to electronically activated colour changing prints and experiment with how to activate these electronically. We will do a hands-on example of how to work with screen printed inks and include them in your projects. This workshop will cover:

  • simple heating circuits with Mosfets

  • how to deal with high electrical power for e-textiles

  • different heating elements ranging from traditional electronic components to textile integrated solutions (Peltier, Pads, Threads, Eeonyx)

  • printing with thermochromic inks, specifications

  • how to design a colour changing pattern


Basics of Pattern Cutting


In this workshop, we will learn about the basic skills in pattern cutting for clothing. Starting with getting the right measurements, we will create simple 1:1 patterns for items such as a jumper and a blouse (other patterns can be included upon request). Hereby, we will also explore the difference between woven and knitted textiles and the impact on pattern construction. While some patterns can be designed from scratch, I will also provide some templates for more complex constructions. To understand how a flat fabric can then transform into a piece of garment for the human body, we will model the paper patterns onto a mannequin, or cut simple shapes out of sampling fabric.

Weaving Intensive: Rigid Heddle Looms


In this workshop, we will build and work with a simple rigid heddle loom to explore textile structures. We will start with the most basic structure of plain weave and cover other techniques such as: supplemental weft, looped pile, honeycomb and weaving with multiple heddles. We will look at how we can create custom conductive textiles with whatever properties and out of whatever materials we want.

Intro to Audio Processing with Bela


Bela is an audio processing platform built on the BeagleBone that is designed for creating new musical interfaces. It can be programmed in a number of languages, but we will start learning how to use it with Pure Data. Sensors and actuators can all be controlled from the code, and since it is a full Linux computer, it can do much more advanced audio processing than is possible on an Arduino.

Beyond learning the basics of working with the platform, Becky will also show some of the work she’s been doing to make it easier to connect e-textiles to Bela.

A kit will be provided during the workshop, but please bring your laptop with Pure Data installed and a pair of headphones. If you are interested in purchasing a Bela kit to keep, get in touch with Becky to make arrangements and she can bring it along to Spring Break.

Pressure and Presence Sensing


The well known resistive pressure sensor made with velostat, but now with a twist: the same sensor can also be used to measure presence using capacitive sensing. By combining both sensing methods, the same hardware can work both as distance sensor and pressure sensor! We will briefly cover resistive sensing and capacitive sensing and then get our hands dirty by making such a sensor ourselves.

The workshop assumes you are familiar with Arduino and basic electronics such as a voltage divider.

Body to Body: RFID + PAN Workshop

Ingo + Nicole

The Workshops introduces two wireless data transmission techniques: RFID (Radio-frequency identification) and PAN (Private Area Network)

In this workshop, participants will learn about PAN and RFID wireless systems. Ingo and Nicole will introduce basic theories behind the technologies and introduce a DIY implementation of these systems to pass data through bodies to other bodies. Specifically, we aim to build the circuitry to read RFID Tags and send the data over to another body using capacitive coupling.

e-textile Sound and Music

Adrian + Martin

In this hands-on workshop we will explore popular strategies for making sound and music and how they might work well in e-textile designs. We will make sound using analog circuits (555 and 556 timers), Arduino 32u4s (Lilypad USB, beetle) and faster ARM based chips (Teensy 3.x). We will also look at how to bridge from e-textiles to high quality/complexity sound synthesis via MIDI and OSC. We will also see how sound transducers such as speakers and microphones can be built intrinsically with textiles.

There are no prerequisites for the class, but if you prepare the following you will gain 30 mins more time to play at the workshop: Installation of Arduino 1.8.5 and Teensyduino on your laptop; Building a simple electronics project with a breadboard or solderless breadboard (10+ connections). Materials will be provided and the microcontrollers will be loaned.

To Own or Not to Own?

Many of us straddle a world of open source and intellectual property. How does one inform the other and how do they coexist? Who currently owns what and does owning IP or enforcing strict open source licenses, such as copyleft, help or hurt the growth of e-textiles and accompanying software? Does this define a line between artisan and industry? Both approaches have their own wicked strengths and weaknesses. What impacts might both have on society and who benefits? What might a harmonious relationship between them look like as it pertains to e-textiles? (A debate structure is encouraged by participating in this focus group)

Your Wildest Speculative Fantasy

GET WEIRD. We spend much of our time thinking through current, practical, and marketable constraints that dreaming the not-so-near-future and the impossible gets pushed to the wayside. What are your deepest and most fantastical e-textile desires? How does one look to the future in order to design for the present?

Revel Off the Grid

Run off the grid. Turn it upside down, inside out, and flail all about. E-textiles often defies expectations, especially in a performance context. Let’s take it to the extreme and break all the rules as we imagine new possibilities for performance. What will our interfaces look like? What new aesthetics will we find? Do e-textiles inform new ways of movement, does movement inform e-textile interfaces, or is it a combination of both?
