Dyeing Conductive Yarn
Conductive yarns are often in gray color which makes your project looks grayish. What if we color them in different colors so we can explore the aesthetic expression more freely, or match the conductive yarn color with the rest of the yarn to hide it completely? I have made a trial to dye the conductive [...]
EL panel/wire inverter hack
EL panel and inverters are interesting material, but rather hard to control since it involves inverters with AC current. There are some nice tutorials on how to control AC side with triac or EL sequencer at sparkfun, buildr.. so on. But I always had a bit of problem when I want to fade them slowly, [...]

simple heat circuit
You can make a simpler heat controlling circuit using TIP122 transistor. The above image is the schematic. If you want to control a lot of heat lines, you can use shift register between arduino and input pin of TIP122. This method is not good if you turn on/off the heat in high frequency. TIP122 will [...]

ATtiny 7-Segment Display
This circuit uses the ATtiny 8-pin microcontroller which has 5 I/O pins to create a 7-segment display. Since a 7-segment display only requires control of 7 individual LEDs, we use 4 of the ATtiny I/O pins as charlieplexed outputs (n*(n-1)). Leaving the the fifth I/O pin to be used as digital or analog input or [...]

Inspired by Marcelo Coehlo’s paper speaker and Vincent Leclerc’s Accouphene textile speaker, these paper and fabric speakers are made by running 5-9V sound amplified signal through a very conductive coil in close proximity to a magnet. Unlike most speakers that have the wire coil wrapped cylindrically and placed around the magnet, here the coil is [...]
Chris Palmer demonstrated how to pleat fabric using a technique of pre-stitching it together with thread. More about his work and technique, and the patterns for the folds are all documented in his book Shadow Folds.
An example using the lilypad arduino sewn to a pillow with a speaker and fabric tilt sensor, playing a different note for each petal of the sensor. The pillow also has an analog pin broken out to one of it’s corners to be connected to any external analog sensors to make noise.
When you need you conductors (wires) to be stretchy, one option is to crochet, knit or braid a conductive thread (or even a wire) alongside some elastic. Make sure to tension the elastic as you go so that ultimately the elastic bunches together the strand, allowing it to stretch a certain amount.
Using an embellishing machine to felt a black conductive felt (by Eeonyx) to a non-conductive felt.

Thermochromic inks are pigments that change color to colorless at certain temperature. There are many different types of thermochromic pigments including textile inks for textile screen printing. Usually you mix normal textile pigments with thermochromic inks so that it looks like the ink is changing from one color to the other. For example, if you [...]
Crochet/Knit Squeeze Sensors
This squeeze sensor can be made by knitting or crocheting a ball including resistive yarn. The ball can then be stuffed with different materials to achieve different kinds of squishiness. The ball can also be hand or machine felted, giving the surface a more uniform appearance.

There are a range of different possibilities to connect conductive materials. One of the hardest and at this point very relevant one in textile electronics is the hard/soft connection between conductive textiles and traditional components and circuit boards. Most connections are a combination of permanent and plugable (de- and re- attachable) connections. Here we try [...]
Sewable Surface Mount LEDs
If you want to include LED lights in your projects, one of the classic options used to be to wind the legs of a through-hole LED around the tip of a pair of needle-nose pliers, making rings that could then be sewn. Another option introduced by Leah Buechley, was to solder tiny metal crimp beads [...]
Seam-Ripping Continuity Meter
This seam-ripper has a continuity meter built in. An LED lights up to indicate when an unwanted electrical connection is made between the tip of the seam-ripper and the part of the circuit that you wish to disconnect from. An alligator clip can be connected to different parts of the circuit, so that you can [...]
This pincushion design has strips of conductive fabric adhered to its surface, so that metal pins or component contacts that protrude through the same piece of conductive fabric are electrically connected. This cushion can be used for prototyping electrical circuits as well as for string pins, needles and components.
Vibrating Crochet Hook
This vibrating crochet hook can be used to measure the resistance of a crochet stretch sensor while it is being made. Continuity and resistance can be measured while the sensor is being crocheted. The vibration motor is powered by a 3V coin cell battery. The less resistance, the stronger the crochet needle will vibrate.
When you knit with conductive yarn, it changes the resistance when stretched. So, I thought of making an accelerometer with same principle. The weight at the end pulls and stretches the knitted structure as it gets accelerated. It works the best when this sensor (more of an object) is turned around like hammer throwing, or [...]
Needle Felting Conductive Wool
You can make a conductive felt with conductive wool. This method is used to make a conductive carpet for airplanes and other shielded place. I have used needle felting method to make a conductive pattern on felt. This conductive wool’s property is something similar to conductive yarn‘s. When you squeeze the ball of wool, the [...]
Conductive wool is perfect for felting. It is very fine conductive fibers (steel) mixed with normal wool, or with polyester. The one with wool works better for felting. I have purchased this from Bekaert Bekinox W12/18 Bekinox PES 12/50
Large Analog Input Matrix
This 28×28 matrix was used in the rSkin project to visualize pressure and location of pressure applied to a rectangular neoprene pressure sensor matrix that was wrapped around a robot arm.
Super simple circuit using a 8-channel multiplexer. Metal beads strung on conductive thread are connected to each of the three control pins so that they can swing and make contact with either GND(-) or VCC(+). 8 LEDs are connected to the 8 output pins of the multiplexer. The various combinations of the beads touching plus [...]

Plated Fabric Traces
Copper plated traces are flexible and solderable. Start by painting with conductive paint directly onto the fabric where you want the copper to plate to. Then you’ll need to prepare the plating process. It takes only a few minutes to get a nice layer of copper. More information on the plating process can be found [...]

By using high-resistance conductive thread instead of conductive fabric, you can make a slider (potentiometer) with zippers. Unlike zipper switch, this sensor gives analog values instead of “ON/OFF”.
A Zipper is a great clothing material that can be converted into sensors. Zipper switch is a known technique used in many projects like TV-B-Gone-Hoodie by Becky Stern. It is also introduced in “Fashioning Technology” book by Syuzi Pakhchyan.
DJ Hoodie is a wearable interface that includes 4 channel zipper switch, fabric buttons with LED indicators and fabric pressure sensors. Two of these hoodies are connected with knitted stretch sensors on the hoods. It interfaces with computer with arduino using Firmata library and Pduino.
