PartyMode is a series of three projects, from 2007 up to the present, to create audio systems with sound-driven visualizations that integrate unobstrusively into an otherwise non-party space. The first of its three iterations was created in a shared lab space, while the latter two were built in residential spaces.
CALCnet 2.2 is a robust networking protocol and driver for two-wire devices, designed especially with timing for 6MHz TI graphing calculators. It is the culmination of a long-running, occasional project of mine dating to at least 2000, to allow more than two calculators to communicate at once. The final published version was demonstrated to work properly on networks of nearly a dozen calculators, and has also been tested on networks fragmented across large geographic areas.

Applications of Convolutional Neural Networks to Facial Detection and Recognition in Wearable Computing and Augmented Reality

A real-time, fault-tolerant and easily deployable solution to detect rip currents using a wireless sensor network.

The Multichord musical instrument is an electromechanical acoustic stringed instrument with a single string, the culmination of a project to build an acoustic instrument capable of playing multiple notes without fretting or manual, time-consuming retuning.
The Ultimate Calculators were a series of TI-83 Plus graphing calculators modded with backlights, PS/2 peripheral ports, a touchpad, case mods, and paint jobs.

Pre-dating “IoT” as a concept, the SMSDoor was an electrical doorlock that could be controlled via AIM, SMS message, or a webpage, with user-based access control.
Miscellaneous and otherwise undocumented hardware and hardware design projects from throughout my life and career.
