My Beautiful Circuit


In my beautiful circuit assignment, I have constructed and designed a pouch made for men and women. It is made out of cotton muslin, one undyed but silkscreened a geometric print and the inside is nature dyed with woad. I machine sewed the pieces together, added a white zipper on top and then began the process of putting my circuit together. I hand-sewed conductive thread in a square shape to go along with the geometric print. Placing the power source inside the bag prevented the design in the front to be unobstructed. I wanted the light to be a simple addition to the designs and that only shut off if you pulled out the battery.

Beautiful Circuit – Madi

I was motivated in part to do my project after reading about an autistic boy in a school in the US who was bullied for his inability to read body language of his peers, which is a common issue for people with developmental disorders. I wanted to create a shirt that would be able to communicate basic emotions based on the wearer’s body language, which would press one of the soft switches in the shirt depending on their pose. I decided on three emotions to represent a positive state (“calm”), a negative state (“tense”), and something in the middle (“sassy”). I assigned each emotion a coloured LED (calm = green, sassy = yellow, tense = red), then sewed each in to the shirt in parallel connected to a battery holder running 6V. I had to work through a lot of different design models to find a way to route my conductive thread through all the components without shorting or looking too messy.

This is my circuit diagram:


where you can see my three LEDs, two resistors (the yellow LED was too faint for a resistor), and battery pack.

I started by embroidering the words and connecting the negative sides of the LEDs to the battery pack on the back of the shirt

Then I sewed in the soft switches, made with conductive fabric on either side of a thick neoprene fabric with a hole cut out


This is the illustration of how my circuit ended up laid out on my shirt

Suspended Circuit

For this first assignment, we’ve been tasked with creating a functional circuit where the conductive materials combine to make up a significant portion of the aesthetics. So for my work, I’ve taken inspiration from contemporary suspension bridge designs, as well as a line of furniture products by Robert Cuthburt. Both styles of design use a system of tethers hung from a single tower to span a gap, and support a deck.



My ‘bridge deck’ and ‘tower’ are simple wood constructions, however the cabling is an alternating rhythm of red and black silicon wires. I have run two separate circuits off of a single battery, each ending in a single red LED to show when it is operational. Paying attention to the precision of my layout and craftsmanship, the battery and transistors are discreetly pinned to the underside of the deck.

Nicole Calzavara’s Beautiful Circuit



The project consists of a glove, and a crystal skull.  The glove contains circuits and conductive aluminium pads on the palm, and the skull has a cork top, with a 10MM LED in the top, powered by more conductive aluminium pads.

Above, Right to Left: The parts to the piece.  A glove with conductive circuitry, a glass skull, and a cork with a 10MM LED and Conductive plates.


Above: An interaction of placing a hand on top of the skull to complete the circuit.  A person would put on the glove, wrap the strap around the hand which would complete half the circuit and battery pack, and grab the skull on the conductive aluminium plate to illuminate the skull.

The project’s main goal is to provide light in a alternative and dramatic way.  The interaction is by grabbing the top of the skull, on its bottle neck, conductive plates in the cap power a hidden LED, illuminating the clear skull.


The power is requiring a connection between conductive plates, illustrated above.
