I made a new blog post, and in it I show how I build a device to monitor the voltage of a 12V battery and share it over the Internet. Something that might be useful for remote astrophotography rigs or when building off-grid power installations. I'm using a Raspberry Pi Pico and some basic circuitry to make it all work. Take a look!
