In this video, @lorrainbow tackles a familiar café problem: noisy spaces and unclear order callouts. Using a @raspberrypi Zero, keypad, OLED screen, and USB audio, she designs a compact announcer that plays clear, pre recorded numbers at the press of a button. Along the way, she works through real world challenges of a queue management system, from slow installs on the Pi Zero and audio format conversions to keypad wiring, enclosure choices, and building a phone-based workflow for recording and uploading clips. The result is a practical, human centred project with potential far beyond cafés, including accessibility-focused communication tools, find the supporting files and other projects on the #element14community : bit.ly/4vfcCWZ
