I thought I'd share my solar powered website as it stands, along with the
offer of any help I can give should anyone run into problems I might be
able to help with.
* It uses an ina219 to measure the state of the battery (Thanks Roel!)
* I'm experimenting with changing the background image depending on the
weather. I'm intrigued by the idea of physically situated servers tied to
their place in space.
I have yet to tackle the data optimization or server customization and
caching, and logging the power usage to look at trends / see if I can cope
with a Danish winter (unlikely at this point). And I am proxying to my site
on nearlyfreespeech.net when the pi is down. I'm rather attached to uptime
at the moment as I am looking for new opportunities in the realm of playful
learning and sustainability.
Thanks for to you all for making this list / club, and for your
contributions to solar.lowtechmagazine.com and associated documentation -
which I found to be really inspiring.
I've got my personal website hosted on a rasbperry pi 2 in my workshop.
I want to make some design changes in the coming weeks to localize the
server in space and time, and play with the idea of emphasizing solar. I
need to get some data from my solar rig (12 volt, 40 watts of panels, and
4 AH lead acid battery) to display on the homepage. Anyone have suggestions
as to how to get things like battery voltage / charge state from a solar
rig into a raspberry pi? I've been looking at various "hats" but haven't
found one that makes it easy.
