Fabric Speakers
You can create a speaker out of a coil of conductive material, a strong magnet, a membrane, and an audio signal. Traditional speakers use harder components to build loud, efficient speakers. Here we will explore how they work and how to construct a textile speaker What is Sound? Sound is a type of energy […]
Custom Mono Amp for Textile Speakers
If you want to work with textile or paper speakers, this is a handy tool to have around. You can use it to connect your speakers to any device with an audio output like this: TOOLS Diagonal snips Wire stripper Soldering iron Lighter MATERIALS Lipo socket Mono amp Audio cable Alligator clip Heat shrink (different […]
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 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 […]
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).
