Draft case study, scaffolded from project notes. Refine the narrative before publishing.
Context
DavIO is a prototype entertainment and communication system I built for my brother, an adult with severe physical and mental disabilities. The goal was to give him a way to make choices on his own — to select between several buttons and play sounds, trigger lights, or activate whatever he wanted in the moment.
Approach
The system runs on a Raspberry Pi, wiring physical buttons through GPIO and driving addressable lighting via WLED, with custom circuit design to tie the hardware together. It can also be controlled through a web app. Different modes let it switch between arbitrary “scenes” — Communication, Entertainment, and Night — so the same set of buttons takes on different meaning depending on the context.
Outcome
A working prototype that gave my brother a measure of agency and choice, and a flexible scene-based foundation to keep building on.
