Quiet, and Sometimes Silent

Quiet, and Sometimes Silent is an on-going project that explores proximity, intimacy, and subtle communication. Two DIY wearable pieces talk to each other through LoRa, a wireless protocol that enables small data-packet transmissions using a free, hobbyist radio frequency. As two people approach each other, their headpieces morph into different shapes – flapping, shrinking, producing buzzing sensations and movements. Together, they turn into mutating sculptures, communicating with nonverbal subtlety. This project draws correlation between protocols outside of heavily surveilled mass superstructures and the state of acquainted human relationships, exploring the idea that small movements and sporadic data exchange can resemble our loose social connections with the people around us.

An exploration of Wi-Fi Aware for Bitchat (and other ad-hoc networks) - HackMD

Bitchat is an open source peer-to-peer mesh communication network started in the summer of 2025 by Jack Dorsey. It's available on iOS, Android, and MacOS. Others have explored beyond this, with a terminal client and a self-powered ESP32-based mesh relay node. In theory, Bitchat enables cross-platform peer-to-peer messaging even when there's no cellular or Wi-Fi network available. In practice, it's not proven to be reliable in an offline environment. However, I believe it could be, and it's clear that the team agrees and is actively working toward that end.
