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 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 Switches

Circuit Here is the circuit to use to connect your soft switch to an Arduino. These swatches use the button sketch in the examples. BUTTON Momentary switches (aka push buttons) stay open as long as you hold them by pressing conductive materials into contact. Demo Construction STROKE SENSOR Close the circuit by pressing conductive materials […]

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 […]

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 […]

Stretch Sensor | Human Breadboard

This is a swatch created for the Human Breadboard Project and Kit of Process created at eTextile Summer Camp 2015. I discovered this prototype near the serger on Day 2 of eTextile Summer Camp that I believe was from the Wearables group. I got excited about it and decided to make one myself. I switched […]
