Final project for Interactive Device Design
Professor Björn Hartmann
Production Period: seven weeks
Motivation:
In response to a recent power outage and explosion on the UC Berkeley campus, we wanted to develop a low cost device for peer to peer communication that can function independently of external power and communication networks. The existing text-based campus warning system was highly ineffective - it was delayed and when it did appear, it lacked in details.
Solution Overview:
In the absence of external power and communication, we want to empower the general public to spread relevant information instead of fully relying on centralized authorities. The device contains a microcontroller, wireless transceiver, and simple inputs and outputs: leds/buttons/switches/piezo.
In addition, the device's basic I/Os can be augmented by a smartphone through communication through the standard TRRS audio jack.
Team Members: Alvin Yuan, Lanssie Ma
My Responsibilities: Electrical and mechanical design of entire device, some microcontroller programming.
