PComp Final Project » Concept

I have always been intrigued by the possibility of generating sound from relating disconnected factors that, at first, seem completely unrelated. It is not a secret that sound is a major subject of my work, as an artist, designer and musician. That said, this opportunity of developing a work that requires the exploration of all the […]

Thoughts on Sisyphus

A obra incita um discurso de comum abordagem na arte contemporânea – atua no paradoxo do absurdo e do inconcebível. Entretanto, não é uma tentativa de desvendá-lo ou até mesmo trilhar caminhos que levem ao encontro de uma única resposta. Pelo contrário, aborda o mito de Sísifo ao posicionar o absurdo à frente do sujeito. É […]

Synthesizer Demo

  This is the outcome of the Physical Computing mid-term. The synth has a full diatonic scale composed of twelve pushbuttons, four knobs (amplitude, wave, cutoff frequency and resonance) and a light dependent resistor that controls the pitch bend. All connected to Arduino and communicating to Processing via serial. Processing is responsible for generating sound […]

Synthesizer » Construction

These are pictures of the construction of the mini-synthesizer. It shows the recently soldered sensors: twelve pushbuttons that composes a diatonic scale, four potentiometers (amplitude, wave, cutoff frequency and resonance) and an LDR for the theremin-like pitch bend. We’re one step away from the goal line.


If on a wiseacre’s nightlife a treadmill… I love this: ” The attempt to live under the premises of rigor is a defiant act” yes it is… and ” it takes a lot of courage to do it” Also I like your description of what reading the Calvino meant to you. Now, here’s a question. […]

First Test » PComp Synthesizer « Mid Term

    This is the first attempt to create a synthesizer for the Physical Computing mid-term. The pushbuttons correspond to a scale, each one was assigned to one note of the diatonic scale.  The first potentiometer controls the amplitude of the wave; the second allows the user to choose between different types of waves; the […]

Variation of previous work. Now, instead of a continuous changing sketch, the drawing remains on the screen. The FFT analysis is responsible for defining each R,G and B values. code is here.
