Rotary Phone Connected to AI Agent

FinanceYF5 · x · 2026-07-10

Karen X. Cheng and Justine Lu collaborated on a project connecting a 1920s rotary dial phone to an AI Agent, using a mechanical display to reply.

Cursor assisted with coding: picking up the phone triggers recording, sending audio to an LLM for processing. Cursor also helped query Vestaboard's API documentation to route AI replies to the mechanical display board.
