Below is an evolving list of project topics. Feel free to add your ideas to this list.

Indoor agriculture: Moisture & Ph sensors, automatic watering.
Reactive room: Sense people entering, face them, and interact.
Semi-Autonomous Driving: Lane keeping, parking, etc. with small robotic vehicles.
F1-10 autonomous driving: (by special permission) See http://f1tenth.org
Accessors for IoT devices: JavaScript environment for composing sensors, actuators, controllers
Wearable LEDs: Sensors controlling wearable displays.
Smart lighting: E.g., lecture hall that automatically adjusts lights based on usage.
Interactive art: Constructions that engage the viewer.
Interactive holiday lights: Engage people, save energy.
Automatic pet water supply: Monitor intake, alert to refill, etc.
