i went to find some solar punks to talk about this retarded looking battery with, but i found most of them had never touched a solar panel, or built a battey to store power. they just draw pictures and argue about the future. who knew🤷
anyway, this ugly ass battery has charged all of my devices and provided light in the evenings for the last two weeks just being charged by a small 50watt solar panel during the day.
Function over form. I find it incredible that you've built a system which works FOR YOU, fuck what the rest say
The word solarpunk is already taken
Wish I was a bit smarter like my dad. He wanted to turn my diesel generator to be some kind of a hybrid. Now he is extra smart but extra far. He was describing me all into details. And there i was on the other line staring as a cow, thinking: " Aaw... how cute my dad thinks im smart" ... so i pray for God for my dad to visit so I get me some of that comfort too... 💀😄✨️
If it work, it ain‘t stupid 👍
Sick radio bro
My current #wip.
Playing with high voltage DC does mean extra precautions should be taken, though:
12V stuff is so dead simple everyone should do it. 48V battery packs and kilowatt strings of panels can kill.
This looks functional and I would like to start with something similar for my tree farm. Where did you source the batteries? I'm in Puget Sound area and imagine they coast a fortune to ship.
Also, I echo nostr:npub17nvfw7g53nxjghyd2zg552z06cke0jc0k69hj7ns7f9pw26j9kusap4u85 admiration for the radio. What is that setup?
Some day I would like to integrate some solar+battery power stations with HaLow nodes. I've been enjoying reading nostr:npub1ya20ep3dd0qt0suhzprxztv5y43arqwps73ercvqa44sp7qw0edsp4x9ty
the batteries were from a poorly configured delivery van, that still had some good cells when it was rebuilt.
i imported 8 200Ah LiFePo cells from china for another battery i built. it wasn’t cheap, but it was cheaper that other options.
The radio is basically a Baofeng uv-5r. just an even cheaper off brand. it serves well as a basic access device
That's a Quangshen 👀
Very moddable. Fun learning device.
Thank you. Was on the tree farm all weekend. At the moment those times are a 'data diet' for me as I use a metered Google Fi plan. It is handy to have access to a data-only sim that I put in an ebay peplink max, but $10/GB encourages me to curtail my bandwidth dramatically and enjoy the woods. :)
not to curtail your silent time, but silent.link data is so significantly cheaper. i’m paying $1.60 per gig. and its no kyc, payment with lightning ⚡️ 🤷
then again, having a compelling reason to turn it all off is compelling too.
Thank you, again. They are on my radar, for sure. I appreciate you sharing your experience. It's always good to have a choice of activities.
If I may ask your advice, I am trying to figure out how I could make silent.link work for me.
I bought a peplink max cell modem/router off ebay for cheap, flashed the most recent firmware and popped in my Fi data only SIM. That gets me a fairly stable, if low speed and expensive internet connection on the tree farm. I have a Pi4 plugged in via cat6 cable and I can ssh into the Pi using a tor hidden service or zero tier. I use the Pi to get remote webcam views to keep an eye on things.
It seems like silent.link uses an eSIM. I gather I could probably get this to work on my Pixel+Graphene, but I need a full time data link at the farm, even when my phone travels back north with me. What are you using it with? I guess I need to research other cheap cell modem/routers that can use eSIMs...? First few I looked at were way more than the $50 the peplink cost me used. Any recommendations?
there is a company which provides a physical sim card which you can load eSIM profiles onto.
They have an app you can use on an android phone to load the esim profiles. its found on the FDroid app.
Cost for card is about $40.
link to fdroid:
The amp is called JMP esim
you can purchase a programmable sim card from within the app.
also, this is their website. they offer a variety of services…
a caveat with silent.link…
your location will show as Poland. 🇵🇱
Brilliant - thank you!
How big is a 50w solar panel?
Should the battery be out in the elements like that?
Are those essentially car batteries?
