Heating Circuits for Thermochromic Inks

Thermochromic ink changes state in the presence of heat. When any heat source is applied (e.g. body heat, hair dryer, or electrical current), the pigment turns colorless. Here we will assume you want to use current to control the pigment color change. In this overview, we’ll look at: Variables to consider Heating elements Circuits Choosing […]

Thermochromic Tests

Thermochromic Tests

Thermochromic pigments change states when you introduce heat. You can control how much it changes by passing current through resistive thread or other resistive materials. Here are a few tests with different threads and resistances. For more information on how it works, the circuit, and other resources, go here. Thread: Stainless steel Resistance: 10.2 ohms […]

Soft Sensors

Circuit Here is the voltage divider circuit to use to connect your soft switch to an Arduino. If you want to learn more about voltage dividers, check out this post by Sparkfun or this post by Kobakant. Code Here are links to different Arduino sketches you can use with these sensors: Fabric Sensors. This combines […]

LED Sunset Tester

I have been wanting to play around with using Kapton sheets as a circuit base for a while now after seeing all the fun things Kobakant has been making with it (like this Ohm Broach). I decided to create a quick LED tester that I can plug right into the Arduino instead of having to […]

eTextiles as a Site for Speculative Storytelling

Posted on Jun 19, 2018 in Craft, In process

I wrote this recently for an application and while I have no formal, more contextual place to share it at the moment, it sums up much of the thinking I have been doing over the last 6 months. The power of speculative fiction lies in its ability to suspend the ingrained stories we tell ourselves […]

Soft Circuit Storytelling at Virginia Children’s Engineering Conference

Soft Circuit Storytelling at Virginia Children’s Engineering Conference

Overview I was invited to give a workshop by the wonderful folks at the Virginia Children’s Engineering Conference to 50 elementary school teachers.┬áParticipants built blinky name tags that showed our emotions, learned about how electricity moves, questioned how different LEDs “eat” voltage, collaboratively wrote stories, and created our own interactive storybook covers out of paper, […]

Computational Craft Zines!

Computational Craft Zines!

This summer, Becky Stewart gave a wonderful workshop on the Math Behind Circuits. Instead of lecturing us at a white board (which she would never do anyway), Becky busted out that wonderful little nostalgic nugget of punk self-publishing: the zine. So broadly applicable, so unintimidating – a perfect format for teaching complex topics to novices. […]

Pressure Sensor Matrix

Pressure Sensor Matrix

This pressure sensor matrix allows you to detect where pressure is being applied in a specific location. It is an adaptation of Kobakant’s pressure sensor matrix (design here, Arduino code here, and Processing code here). Materials + Tools: + Stretchy Conductive Fabric from lessEMF + Eeontex Stretchy Fabric from Sparkfun + Karl Grimm Conductive Thread […]

Sonic Quilt Resource Gathering

Posted on Oct 17, 2017 in Craft, In process, Tutorials

Below are a collection of resources for the Sonic Quilt project. Following the first exhibition of the prototype, I found there is much room for iteration. In the second prototype, the goal is to embed each individual quilt square with its own audio player. The initial version used the Audio FX Board by Adafruit, but […]

Crafting Technology 101 Workshop

Posted on Aug 27, 2017 in Craft, Learning

On August 9, I had the delightful honor of presenting to a group of young ladies (14-15 years old) who are participating in the GOALS for Girls program housed at the Intrepid Museum. A big part of this program is to bring field experts and mentors in to speak to the girls about different disciplines […]
