Collection of E textile Swatches.

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.

The dress of swatches could symbolize or give an impression of the complexity of our skin.

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.

Circuit1.jpg Big ring of metal used as a switch.

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.
Charlie.jpg Tilt sensor made of three conductive patches which form a circle.

The circuit is closed by swinging the bead over these patches.

Example of low tech sensor.

(Coming.)
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 with LCD screen and 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.

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).
