Collection of E textile Swatches.

Collection1.jpg 
Swatches in progress
These swatches contain a fabric part and an electronic part. 
Often electronics and fabric or other materials are intertwined, 
mixed, used by each other.
Swatch dress1.png Swatch dress2.png 
The dress of swatches could symbolize or give an impression of the complexity of our skin.

Textile components

Some of the electronic components can be made in fabric.

Coin battery holder.jpg In combination with conductive wire, within the two layers of fabric.
Soft5.jpg A button in a circuit, one layer of aluminum foil, then a layer of fabric with a hole, then another layer of aluminum foil, sandwiched.
Soft2.jpg The folding of the conductive aluminum foil closes the circuit.
Conductive1.jpg conductive yarn, made of tiny metal fibers, so conductive.
Copper13.jpg Copper wire, coated, sewn on the fabric. Used as a coil, with magnets underneath becomes a speaker.
Button5.jpg Using metal buttons as a conductor, making this into a switch.
Cond wool1.jpg metal wires are mixed with wool, this made into a yarn. Stretching means changing the reistance - not very linearly.
Alu1.jpg Buttons, made of aluminum foil and Vliesofix.
Battery holder AA.jpg You should press the aluminum foil against the battery, making this into a battery holder plus switch.

Circuit, buttons and switches

Using fabric gives rise to an infinity of possibilities in closing and opening a circuit. Aluminum foil is a very cheap material compared to the expensive metal weavings.
Button1.png Buttons of metal, used for trousers as a switch.

You can get the buttons at the Fabric Station.

Circuit1.jpg Piece of aluminum foil on fabric using flysofix as a switch which folds to close the circuit and start an led.

ATtiny85 swatches

The ATtint85 as a cheap workhorse.
Charlie.jpg Charlieplexing, 8 leds connected to the four pins of the ATtiny85.
Fold.jpg Folding with ATtiny85 and 5 leds. An example of interaction between material and led.

Sensor swatches

Sensors are one part of the sensor, actuator, microcontroller trinity.


Ldr1.jpg LDR in combination with a fixed resistor.

ATtiny85 can blink with 2 leds.


A script can make the leds blink, glow.

Therm.jpg Themistor (NTC) with a fixed resistor.

ATtiny85 can blink with 2 leds.

Pressure.jpg Pressure sensor with a fixed resistor.

ATtiny85 can blink with 2 leds.

ThreeSB.png Four sensor body.png Arduino Pro Mini - for more power than an ATtiny85.

LCD screen

3 sensors, light, temperature and pollution.

Lipo battery plus charger.


Led swatches

The variations in leds is endless. Interesting is the difference in voltage between the colors, which might lead to surprises if you connect different colors in parallel.
Different1.jpg Different red leds, from 10mm, 5mm, 1mm and an smd led.
Charlie.jpg Parallel leds in a circuit with an open connection, use something conductive to close the circuit. 
Coming soon.
Neo1.jpg RGB neopixels. ATtiny85.

One of the neopixels is covered by filling and cloth to investigate the effect of the light under fabric. 

(Coming.)
Copper1.jpg A piece of copper strip with smd leds soldered on the copper strip.

Parallel connections.

555 swatches

The 555 is an old component, used for a timer, but also for making noise, sirens and alarms.
Ts2.png Textile speaker. 9V, use of magnets.

The 9V is necessary because the textile speaker is producing a very low volume level.

LDR for variable input, causing the tone to rise and fall.

Conductive Wool swatches

Wool1.png Textile Synthesizer

Using a knitting of conductive wool inside a voltage divider.

Speaker gives a low to high tone, depending on pulling the conductive wool

ATtiny85, 3V.

Wool2.png Circuit with two strings of conductive wool

Using two voltage dividers

Two LED's to indicate which side is touched - pulled.

ATtiny85, 3V.

Transistor swatches

Transistor acting as an amplifier and as a switch.
Darling1.jpg Darlington array. By amplifying the signal with 2 transistors you can detect if a human touches a pad of aluminum foil.

You need to touch both pads.

Trans1.jpg Transistor switch.

LDR in connection with a fixed resistor makes the BC457 into a switch.

Joule0.jpg Joule2.jpg Joule Thief.

A double coil and a transistor act as a boost circuit, so an led can be lit by a 1.5 Volt battery. (No free energy of course). The circuit is activated by closing the two pieces of fabric with all foil around the battery (fabric battery holder - switch).
