Programmer Focus Indicator: The Birth of FlowLight

2024-12-15

Inspired by a research paper on the impact of work interruptions, programmer Shae Erisson DIYed a system called FlowLight to indicate whether a programmer is in a focused "flow" state. The system monitors idle time in the Emacs editor; when the programmer is inactive for a period, an Adafruit MagTag board's LED changes color (green for idle, red for busy). Erisson also wrote an HTTP server in CircuitPython to remotely control the LED color and display status. While the system has room for improvement, such as more granular idle time monitoring and a more visually appealing display, it effectively helps programmers avoid interruptions and improve productivity.
