Index of book




  • Submission of a project of “digital-analog converter with Arduino” at the first edition of the Open Hardware Day in association with the engineer Marcello Marino.
  • Exhibition organized by Nalug in collaboration with the Fablab Naples:

  • The DAC project is based on a 8-bit R-2R discrete network and on a implementation of wavetable and virtual oscillators algorithms for musical applications of sound synthesis with Arduino board:



  • “Interferenze Audiovisive” is a study based on Cymatics, a term that designates a morphogenetic effect of sound waves, where a known example is given by Chladni’s figures, but in this installation we study the resulting effect of sound waves on the water.
  • On a supporting arm are fixed some red, blue and green LEDs, that positioned perpendicularly to the water surface reflect the light toward a magnifying lens, according to specific distances and sizes.
  • A player and an amplifier driving a speaker, above the speaker diaphragm is fixed a support for the water container.
  • A specific composition of simple sound signals, with different duration, frequency and intensity, was synthesized in SuperCollider for inducing vibration motions of the water surface. From this motion derives the illusion of dynamics geometric shape in relation to the parameters of the sound signal.

Installation by Cristian Sommaiuolo, Stefano Silvestri, Dario Casillo

This sound installation has been designed and executed in collaboration with the teacher, and dear friend, M° Giosué Grassia. This new version was presented at the “Festa della Musica” at the Conservatory Nicola Sala of Benevento in 06/21/2014.

Working together has been improved the electroacoustic and electromechanical feedback system in Pure Data and Arduino that in its first implementation has seen the contribution of M°Agostino Di Scipio:

This project is an interactive application written in collaboration with Vittorio Milone and requested from the artist Diego Cibelli, that has wrote and provided the multimedia materials. The application consists in a video and hypertext available through dynamic buttons. The circular buttons are considered as “particles” that can collide. Have been used algorithms for the simulation of a particles system in processing language ( while the code of the web application has been optimized in processing js ( The use of the hypertext is given by clicking on the numbers assigned to each particle different for color and group or text and topics.

Open Bilateral Stimulation (OBS) project is a visual-audio application software and an hardware tactile interface.

OBS is a low-cost open-source tool for psychotherapy written in Processing/Java and Arduino, akin to the so-called visual/aural/tactile EMDR therapy. The method of EMDR – “desensitization and reprocessing through eye movements” – was developed in the United States by Francine Shapiro (1980). It is a complex approach usable either in an autonomous way or integrated into different therapeutic programs, thus being able to increase their effectiveness. This form of psychotherapy was directed initially to the treatment of Post Traumatic Stress Disorder, but is now a widely used method for the treatment of a broader spectrum of disorders in children and adults. The tool reproduces a dynamic image on the screen whose movement has to be followed by the patient. This movement can be customized according to therapeutic needs, by being either continuous or discrete with further variables such as speed, test duration and form of the moving object. It is possible to control the tool by means of low-cost touch sensors.

The project has been realized in collaboration with the “Open Rehabilitation Prototypes” group:

and was presented at the Maker Faire Rome 2th edition:

beta version:

Special thanks to Victor and Antonella!

This is a prototype of an electronic system for an industrial machine commissioned by a Neapolitan company. The operations are basically: the command of a seqenza of instructions for control a solenoid valve and a compressor, with control buttons on the frontal panel. In a new version of the device have been added two temperature sensors, the prototype of a “pulse dimmer” for the regulation of temperature of a tungsten coil, and a potentiometer for adjusting the pulse times. In order to help the user, the state of the actuators and the value read by the sensors is shown on a display on the front panel. The control board is based on Arduino simplifying the work that would be made on PLC system.
