Description

Two years ago, someone on HN shared an interesting ADHD hack: a tiny LED that blinks at 120 bpm and gradually slows to 60 bpm, supposedly helping your brain sync and calm down into focus mode.I found Qiaogun's implementation (ADHD_Blink) for M5StickC Plus, and adapted it for the newer M5StickC Plus2 with some tweaks - simpler 50% duty cycle flash, configurable ramp-down, auto sleep, etc.Honestly, I'm not sure if it actually works. I'll be trying it out myself to see. But the building process itself was quite fascinating.I used Claude Code for the entire implementation - from reading the original codebase, to modifying the firmware, to flashing the device. There's something surreal about an AI having full control over a physical piece of hardware.It made me wonder: in the future, could AI-connected devices dynamically rewrite their own firmware based on user needs? Imagine telling your device "make this button do X instead" and it just... does.Original HN comment: https://news.ycombinator.com/item?id=38274782 Based on: https://github.com/Qiaogun/ADHD_Blink Hardware: M5StickC Plus2 (~$20)Happy to hear thoughts, or if anyone has actually tried this LED trick.
