This project started as a search for a timer that would let conference speakers know how much time they had left in their respective speaking slots. Gemini found commercial solutions, but none really met my requirements.
Then, it struck me that it could probably be done in an HTML file. This was the prompt.
Could you just help vibe code a solution that would work on a MAC or a PC? It only has to have the most basic operation – input the amount of time for an alarm. Input a time before a warning starts (e.g. timer flashes or changes color to deep orange with a minute left to red with 15 seconds left). Has a simple interface for start, pause and stop. Ideally, this would be in another window so that it could be moved to a different display screen. The actual timer could be set to occupy full screen.
It worked! The setup was a PC with a USB-fed monitor. The only flaw was that one of the speakers didn’t look at the monitor, so she didn’t see that her time was up. The second revision of the HTML code adds an audible indicator, a virtual hook if you will, to prompt speakers to finish their talk if they aren’t looking at the monitor.
