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!
@stfn
That's great 'n all, but who is going to monitor the voltage on the battery that powers your raspberry? 😜
But seriously, great work. If I had the time, I'd botch together a solar powered, remote programmable watering system, because I'm too cheap to buy one in the store. 😃
A monitor like this would be really great.
@stfn hi, not my thing, but wanted to say thanks for a clear explanation of "system, purpose, possible uses" rather than "hey I built an nx320 HAT on ESP and the v12s are 100%" that I often see with the #raspberrpi hashtag.
@stfn nice! I'm planning* a pico based solar/battery powered thing for the allotment/polytunnel and battery monitor data would be an excellent thing to have on that.
for over a year, lol, but might actually have the time for it this year....
@yvan Thanks! I have an allotment too, only since last year, so I don't even have a tunnel yet, but once I build one I think I will also add something that you mention. Another project on the todo list :)
This post took a surprisingly large amount of work an time to finish, I even burned one of my Pico in the meantime, probably because I made some mistake when soldering. In the end I'm super glad how it turned out, and I will be using what I made the next time I go do some astrophotography
