Technology, Sound, and Learning: An Experimental Synthesizer for PIXO

April 30, 2025
Celina Collazzi, a senior in the Industrial Design program, developed the Modi.Lab product for PIXO—an interactive synthesizer designed to teach the basics of programming, electronics, and sound by creating sound sequences.

Celina presented the product at the Re|creación 25.  

Features of Modi.Lab 

The device runs on an open-source system based on Arduino, designed to allow users to explore, modify, and learn programming in a hands-on and collaborative way.  

In addition, it comes in a Ready-to-Assemble (RTA) format, allowing each user to assemble and finish the device manually, combining hands-on experience with an understanding of essential technical concepts. 

The device's industrial design includes: 

  • Includes a battery and built-in speaker, allowing it to be used without a computer.
  • Outer casing made of electrostatic-painted MDF and sides made of laser-cut acrylic.
  • Screws and spacers, which allow the device to be disassembled and reassembled as many times as necessary to examine its internal workings.
  • 3D-printed potentiometer knobs made of PLA, customizable by the user. 

The rationale behind the product 

Modi.Lab's target audience consists of teenagers and young adults interested in learning more advanced electronics and programming skills. This was designed with PIXO's need to reach a wider audience in mind.  

One advantage of the device is that it can be used in a variety of settings, from personal spaces to educational environments, and can be integrated with virtual platforms to enhance the experience.

Modi.Lab's design draws inspiration from retro musical devices, which is reflected in an aesthetic that combines neutral tones with bold colors. The design features simple, functional shapes that evoke classic audio equipment from the past. 

The inclusion of a diagonal line in the design—a feature already present in PIXO’s current product—evokes the aesthetic of floppy disks. This choice reinforces a visual identity consistent with the brand and connects the product to a design language that is familiar to its target audience. 

About PIXO 

PIXO is a programming and electronics company founded by Valentina Pereyra in 2021 as the capstone project for ORT’s Bachelor’s Degree in Industrial Design.  

The company is based on an educational kit of the same name, designed to teach children and teenagers about electronics, whether it be programming or video game design.
