Lulu Optic Fiber Swatches – Art using a Teensy and electroluminescent wire #ArtTuesday
A project from How to Get What You Want – Swatches that showcase some of the things you can do with the Lulu Daisy – a design solution to connecting e-textiles, LEDs and optic-fibers.
– 3 swatches
– 6 mini crocodile clips
– 1 breadboard with Teensy and crocodile clip connections for (+3V, GND, Data)
1)”HELLO WORLD”
uses 1.5mm diameter sideglow optic fiber to write text.
code fades between “hello” and “world” revealing one at a time. without the light you can not read what it says.
2)”FUTURE FUNGUS”
uses 2mm diameter sideglow optic fiber inserted into edging. the optic fiber functions both as illuminating material as well as rigid frame that causes the fabric to curve/curl in organic shapes.
code fades LED at either end of the optic-fiber to demonstrate colour-mixing.
3)”TILT DATA”
the data-pin of the LEDs is broken out to petals of conductive fabric. the data coming from the microcontroller flows into the central bead and only affects the LED whose petal it is resting on.
demos 1.5mm, 2mm and 3mm diameter sideglow optic fiber without the cladding, showing effects of cutting into the core to create illumination artefacts.
code fades between colours.
A Teensy microcontroller handles all the control.
See the demo video below and below that more information.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
