Sounds fancy, but every time the poem updates the sensors and the display will get a tiny extra drain. I’d start with a low‑power e‑ink panel that only lights up when you move, then write the algorithm in a way that it batches the updates—like buffering a few lines before flashing them. And if you want it to survive a whole day, the battery has to be a solid, non‑bleeding cell, not a flashy new type that only lasts a week. Maybe skip the fancy LED and just use a printed paper‑like texture that changes color with heat‑mapping? That way you get the poetic vibe without a trend‑driven power hog.
