About the Dyi shell.phone PCB
Dyi shell.phone is an open source Raspberry Pi PCB design by marioguzzzman, published on GitHub under the MIT license. It is a 2-layer board measuring 106.5 × 54.4 mm, with 6 components from 4 distinct parts.
Its main chip is the Raspberry_Pi_2_3, from the Raspberry Pi family. By type, the board carries 2 connectors, 2 diodes and 2 resistors.
It belongs with the audio designs in this gallery.
From the project
Sea Shells, She Tells unfolds as an artistic research project, developing both an artwork, an installation of the Shetells artwork - and a toolkit - the DIY Shell Phone.
This repository is the open-source reference for the DYI Shell Phone, so anyone can build their own, part of She Tells, Sea Shells, an artistic research project, developing both an artwork, an installation of the Shetells artwork, and a toolkit.
The project emerges from the simple, almost childlike gesture of holding a shell to the ear, hearing the ocean’s presence. This toolkit is conceived as a means for the waters of Esposende to exchange with their inhabitants, enabling acts of observation, remembrance, and speculation about the futures of water bodies. Through this, a playful voice is…

Dyi shell.phone: common questions
What microcontroller does the Dyi shell.phone use?
The Dyi shell.phone is built around the Raspberry_Pi_2_3, from the Raspberry Pi family.
How big is the Dyi shell.phone PCB?
The Dyi shell.phone measures 106.5 × 54.4 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Dyi shell.phone?
6 components, from 4 distinct parts. The full bill of materials is listed on this page.
Where can I download the Dyi shell.phone design files?
From the marioguzzzman/dyi-shell.phone repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Dyi shell.phone design in my own project?
Yes, under the terms of its MIT license, which marioguzzzman chose for the repository.
Can I test firmware for the Dyi shell.phone without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Raspberry Pi firmware against it before you order a PCB.
