A SolarPunk Manifesto

Basic Rules:

be constructive: there is no need of another internet space full of competition, negativity, rage etc.;
no bigotry, including racism, sexism, ableism, transphobia, homophobia or xenophobia;
be empathic: empathy is more rebellious than a middle finger;
no porn and no gore: let's keep this place easy to manage;
no ads / spamming / flooding, we don't want to buy/consume your commodified ideas;
occasional self-promotion by active members is fine.

Year-round Solar Water Temperature Sensor (imgur.com)

A small solar power system to run a LoRa water temperature sensor year round. Here's some pretty graphs of the data:

This is a project that's been running for almost 2 years now. Everything is still working with very little down time! The solar power system is way overpowered for what it's doing, but I wanted to make sure it works through the dark winters.

The temperature sensor is at the bottom of a bucket in the ground, because the water level gets pretty low in the winter and I didn't want the ice to destroy the temperature sensor when it drifts.

Any thoughts or suggestions for improvements are welcome!
