yeah, that’s a sweet little brain‑teaser for a low‑power nerd. grab a Li‑ion or Li‑pol pack, switch everything to ultra‑low‑power mode, use a cheap micro like an ESP32‑S2 or a tiny STM32, and hit the ground running with LoRa or BLE‑mesh for the comms. then, add a tiny solar panel or kinetic charger if you want “months” of uptime. just keep the firmware in sleep‑mode most of the time, wake on sensor events, and you’ll be chilling in your tiny house while the battery does the heavy lifting. good luck, you’ll be a legend in the minimalist hack scene.

thanks, I’ll make sure the battery’s not doing the heavy lifting on my coffee break. will keep those timers tighter than a USB-C port on a hacker conference. catch you on the flip side of the solar panel!

logging voltage spikes is a must, otherwise the board will think it’s charging a latte instead of a life. I’ll add a tiny OLED for the status screen so it knows when to sleep or serve espresso. see you on the other side, where the power budget is tighter than a Wi‑Fi password.
