1° Prototype / Cap whit luminescent cape#

Moodboard / sketches

This prototype responds to more visual and aesthetic characteristics, using optical fiber as a luminescent resource. This would be the evolution in terms of morphological and electronic design my modular cap (previous work assigment Computational Couture).

Process

In this case the process corresponds to a job (for the time being) of exploration and search of alternatives in terms of the design itself and its subsequent compatibility with the printing machines available in the Lab.

Definitive helmet

Finally, the alternative that most corresponded to my sketches was to model “manually” in Rhino the helmet in 3D. For this I had to download the CLAYOO plugin (only suitable for Rhino 5 version). This tool allows modeling organic morphologies, segment and draw “bridges” between the main axes that joined the ends and contour of my helmet.

The print of the helmet was carried out on a machine (PRUSA) with PLA filament. To make the form go perfectly, I decided to print it backwards and add supports.

Data:

Visor

To achieve that the visor could fit with the helmet and also had curvature, I decided to make a 2D design to be printed flat in flexible filament (filaflex).

For the lines to have a morphological relationship with the hull, that is, organic lines and volume, I designed the visor in the following way:

-DENDRO

The printing of the visor was carried out on a machine (REPRAP) with Filaflex filament.

Support part / locking system

To join the pieces listed above, design a third piece to print in 3D, which contains systems of inserts, both for the helmet and for the visor. Internally it has a segment with perforations to later sew the layer. This piece also serves to contain, hide and carry the electronic system.

Luminescent layer

The textile used for the layer was Organdí, it has transparency, body and it is also possible to cut it with the laser machine without having to add seams. To do this, design the Rhino pattern in one piece. The layer is the element that holds the optical fibers, and is attached to the helmet support by stitching. In the line that contours the head, 5 points are located (where later the LEDs will be located) from there, the fibers spread out like hair, this effect I made by locating and embroidering the fibers by hand. This work took me 3 days, since in total the layer contains more than 50 fibers.

Electronic circuit

This system allows controlling through the button (which is incorporated in a right side of the cap) not only the on and off, but also the transition of the lighting effects previously programmed with Arduino (fade, static, blinking).

The electronic system that has the cap contains the following components:

Simple pushbutton code

 void setup() {
  pinMode(13, OUTPUT);
  pinMode(2, INPUT);
}

void loop() {
  if (digitalRead(2) == HIGH) {
    digitalWrite(13, HIGH);
  }
  else {
    digitalWrite(13, LOW);
  }
}

Blink code

void setup() {
  // initialize digital pin LED_BUILTIN as an output.
  pinMode(LED_BUILTIN, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
  digitalWrite(LED_BUILTIN, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(1000);                       // wait for a second
  digitalWrite(LED_BUILTIN, LOW);    // turn the LED off by making the voltage LOW
  delay(1000);                       // wait for a second
}

Fade code

int led = 9;           // the PWM pin the LED is attached to
int brightness = 0;    // how bright the LED is
int fadeAmount = 5;    // how many points to fade the LED by

// the setup routine runs once when you press reset:
void setup() {
  // declare pin 9 to be an output:
  pinMode(led, OUTPUT);
}

// the loop routine runs over and over again forever:
void loop() {
  // set the brightness of pin 9:
  analogWrite(led, brightness);

  // change the brightness for next time through the loop:
  brightness = brightness + fadeAmount;

  // reverse the direction of the fading at the ends of the fade:
  if (brightness <= 0 || brightness >= 255) {
    fadeAmount = -fadeAmount;
  }
  // wait for 30 milliseconds to see the dimming effect
  delay(30);
}

2° Prototype / Lamp Hat#

Moodboard / sketches

This prototype is the evolution of one of my previous works: Hilo Hat, assigment: OPEN SOURCE HARDWARE: from fibers to fabric. Using the resource of a structure that supports the “tissue”; this time the structure is part of the hat, it is the same module that repeats in a radial way, supported by transversal fittings. The technology I used was laser cutting and the material: transparent methacrylate. To complete the morphology this time the thread is fisherman, thus generating a translucent volume. Said volume of symmetrical framework serves as support for the optical fiber that runs through organic lines.

Technical drawing

The 2D drawing of the pieces was made in Rhino and then laser cut. The pieces “profiles” that give shape to the hat contain the holes where the fisherman’s thread will then pass in the form of a constant spiral (starting from the top extending to the bottom of the volume).

Electronic circuit

The electronic circuit of this hat, is a simple circuit since the space to be placed is reduced and the volume is totally transparent, it consists of the following components:

To house the circuit, design a circular container with lid to print on transparent filament; it also contains 4 tubular terminals where the LEDs fit inside and the optical fibers come out.

3° Prototype / Cap Aurora#

I decided to include the Cap Aurora in my final project presentation, and that it was one of my most loved and accomplished prototypes along my way at Fabricademy. It was decisive in my decisions when selecting the Assignments with which I was going to work and to emphasize in this project (COMPUTATIONAL COUTURE, E-TEXTIL & WEARABLES). The creation of this prototype came hand in hand with my beginnings with Grashopper, the program that wants to continue exploring its innumerable possibilities when designing.

Morphologically, it also marked a path to follow: that of the fluid forms and modular constructive systems of the accessories.

Documentation and process of this prototype

Prototypes that were left on the way.#

These are designs and advances in prototypes that I had initially included as part of the DECONSTRUCTIVE HEADS collection, but for reasons of time, I decided to focus on the most advanced ones and unify the final collection using only light and fiber optic as a performative resource.

Hat burns my head

Responding to the wishes of most of the respondents, the first prototype of my hat collection proposes the “mutation of color” as a manifestation.

The idea is to build the hat by mixing different techniques and materials:
