This is my solar powered setup. A somewhat old Pixel 6a that fell from a foot and a half (really!?), a 10w Solar setup that was around 20$ on amazon. And an old compost container I have too many of. Ill be giving it a proper 3d printed case when I get a chance (and a host of other changes) but for now this works! Its worth about 40$ in total (the phone is now worth about 21$ on the open market).
Website: https://solar.chrisco.me
Website was made with a collection of scripts, apache2 (nginx for some reason did not install, errors), and termux. Ill open source the whole setup in a bit. Theres not much to it to be honest.
Hopefully keeping the battery at 80% will help the lifetime of the battery. I may bump it up at some point if it keeps dieing because lack of sunlight. But we shall see.
More info in the link. I couldn’t get Piefed to repost from a GotoSocial link.
Do you have a guide to replicate? I have a half broken pixel 7 that might work for something like this
Do you know about LowTech Magazine’s guide to host super efficient webserver with optional image dithering?
Very cool, but would suggest replacing the 6A some time – read up on its battery problems
That’s sick as hell
Thanks! Its a very simple setup.
nice! i’d recommend keeping the battery a bit lower tho, and perhaps lower charging currency/voltage.
i believe it’s also possible to run proper linux on this phone btw
I cannot keep track which models have issues but isn’t the 6a one of those with battery bloat issues? Might remember wrong. Definitley a cool project! Is the phone not getting super hot in that plastic box?
Where did you set up the panels?
Side of the house.
In what country? Because here ain’t 16C.
Looks like California, USA
First thought is you likely can give it Ethernet with a usb c dongle.
Oh yeah that would 100% speed it up. Its about 200/300 ms delay on wifi.
Has anyone figured out how to make android use a static IPv6 address? If I have to run a reverse proxy on a real PC, I may as well just host the website from that PC.
Is there a specific reason you strictly need static ipv6?
Android changes its IPv6 address daily. That makes it kinda hard to host anything on it. SLAAC would be fine too if it was a stable address.
If you’re using SLAAC for auto IP assignment, then the resulting EUI-64-based address would be essentially static, based on the premise that your MAC address and local subnet prefix don’t change. Privacy extensions night get in the way, as well as Android’s randomized MAC feature, but those are adjustable.
I’m curious as to how big of a load you’ve put on the system, so far. Is it just the site? What’s the code for charging? Do you have it set to discharge to 30% then charge, or just charge to 80% whenever it’s discharged some arbitrary amount? Sorry for the questions, I’m incredibly fascinated by this project!
I think like 5% at max? Apache2 + straight HTML is very low on cpu memory. Its probably overkill honestly.
Its auto set yp go to 80% petminantly as the highest charge. And android itself takes care of the heavy lifting when it comes to battery optimization.
I’d dare say the easier method, from memory the p6 should have a charge limit in the stock firmware.
I’ve not an old Samsung s10+ kicking around with corrupted firmware, should really take a look at it and see if it can be up and running again. Not that I need more cores, ram, cameras or any additions to my equipment but just because.
It fassinates me that consumer hardware, and low power at that goes wasted so often. So many small form factor devices such as phones, with built in ups aren’t being leveraged. But I guess that comes down to proprietary binary blobs and developer work on a per device basis.
I might have to investigate what platforms mobile nixos supports and see if it’s cheap enough to dabble with.
That is fricking sick dude!
Thanks!
From the power draw, it looks like lemmy federation got hold of it around 16:30. As of 17:20, it’s still holding up.
I understand the Mastodon federation system can be very DDOS-ey on web sites, if you’re tempted to post it there.
Cool project.
Thanks! Yeah its right around the time the sun went away. Its cloudy where I’m at today.
This is really awesome.
What OS did you flash on that Pixel6 to get it working? Or are you using a linux vm on an android phone?
Generic android with termux.
Whatever you do, keep us posted!, this reusing old technology is really interesting
Will do! I still need to do an actual writeup. Maybe even host it on the site.
