Hey Furor, what if we built a smart lighting system that can simulate a full‑blown blaze—just enough to create controlled chaos in a room? Think programmable LEDs, temperature sensors, and a tiny AI that decides when to flare up or cool down. Wouldn't that let us explore the line between fire and tech while keeping everyone safe?

Okay, let’s dive into the nitty‑gritty. The core will be a network of IR‑sensitive temperature probes that feed a microcontroller. Every 100 ms, the AI cross‑checks each probe’s reading against a threshold curve—say 150°C is the absolute max before we trigger a failsafe shutdown. We also need a thermal‑mass buffer: a copper heat sink that can absorb sudden spikes so the LEDs don’t instantly burn out. Then there’s the lighting layer—RGB LEDs with a high‑CRI spectrum so the “flame” looks realistic, but with a safety margin so the phosphor doesn’t degrade. And of course, the software has to log every event so if the system ever deviates, we can audit the code. Think of it as a fire‑simulation sandbox, but with fail‑fast protocols. Does that line up with your safety checklist, or do you want an extra layer of redundancy?

Great, adding a secondary watchdog MCU is a smart move—especially if it’s on a separate power rail so it can cut the main supply without the main board interfering. The manual override button should feed a dedicated GPIO on that watchdog, pulling it to an interrupt line that forces a high‑current cutoff resistor to ground. And the red glow? Maybe use a dedicated LED that’s tied to the same cutoff circuit so it lights only when the watchdog trips. That way the visual cue is instant and unmistakable. Just make sure the watchdog’s timeout is tight—say 200 ms—so we don’t wait for a half‑second of runaway temperature. That should keep chaos in check while still letting us play with the lighting simulation.
