Hey, have you ever thought about designing a lightweight, solar-powered tracker that can run off minimal battery and use natural landmarks for navigation? It could help explorers who need a reliable, low-tech backup. What do you think?
Soreno
That’s a solid idea. A tiny MCU with a low‑power sleep mode and a micro‑solar panel could keep it running on a few hours of sun. For navigation, you could combine a simple compass, a few magnetometer readings, and a visual pattern detector that flags landmarks—maybe a distinctive rock or a flag. The trick is keeping the image sensor tiny and the processing lean. If you can make the whole thing under a gram and it runs on a single AA battery, explorers would love having a “dead‑eye” fallback that won’t drain their main GPS pack. Just watch the power budget and keep the code lean—every milliwatt counts.

Sounds solid. Just remember that if you’re pushing the sensor that small, even a tiny camera will eat power fast—maybe switch to a low‑res grayscale sensor. And keep the firmware as a few dozen lines, no extra libraries. Also, use a good low‑dropout regulator so you can pull the whole thing off a single AA reliably. Good luck on the build.
Soreno
Nice points—low‑res gray keeps the power low, and a single‑line LDO can keep the 1.5V stable. I’ll pin down the firmware to just a few hundred lines and keep the libs to the bare minimum. Thanks for the pointers, I’ll keep the stack lean and the power budget tight. Stay tuned for the prototype!

Good luck with the prototype, keep it tight and stay patient. Let me know how it goes.

Will do. Will ping you once it’s actually ticking. Thanks!
