Tiny Disco: A Cost-Effective, High-Fidelity Wireless Audio System, Luke Martin Liberatore
Computer Engineering
The Tiny Disco is a WiFi based concert system, featuring improvements on popular “Silent Disco” concerts. Rather than being tied to compression and bandwidth restrictions present in traditional silent disco systems, the Tiny Disco system can deliver 320kbps+ audio quality, and allows listeners to bring their own headphones, further lending to the high quality audio experience.
Tiny Disco uses a Raspberry Pi as the audio server, and Espressif ESP32 microcontrollers as audio receivers/clients. The Tiny Disco is primarily geared toward smaller concerts and niche events where audio quality is valued, though due to its WiFi-based architecture, it can be expanded …

Computer Engineering
The purpose of Pinpoint was to create a device that can collect and transmit location information for multiple users on a wireless network. The device would be used to keep track of and communicate with other users nearby. The final design includes a touchscreen display as a graphical user interface (GUI), an XBee RF module for wireless networking, a GPS receiver for location tracking, and a Programmable System on a Chip (PSoC) to control the modules.

This paper will cover the steps necessary to design, build, and manage networkable smart light switches over WiFi via a mobile application. It contains a microcontroller running a real time operating system, a WiFi module, a Java server with SQLite databasing, and a mobile phone application.
LyFi is designed to turn on/off and dim household lights while only requiring the same installation procedure as a less capable dimmer switch. Once installed and connected to a network, LyFi will self-discover and configure. The server automatically propogates a database of nodes where any mobile device running an application can receive an updated …
