Who said phlog posts have to be about prose?  And who said phlog posts 
can't be "live streamed"?

I am working on a project inspired by the Solar Powered Website[1].  The 
idea is to power a pubnix by renewable energy.  But rather than using 
solar engery, I am trying to use human power.  The goal is to construct 
a gravity battery that will maintain a rechargable battery which, in 
turn, powers a Raspberry Pi Zero w.  As often as necessary, I will lift 
a weight that will then power a generator while it descends.

The first test is to determine how long the pi will run off the fully 
charged battery.  I'm not home most of the day today, so I'm 
"streaming" a date stamp to a file[2] that I can check anywhere.  
When the date stamp log stops updating, the battery has run out. 
[EDIT 2]: Test complete.  The pi zero w lasts about two days, seven 
hours and 26 minutes on this battery.

[EDIT 1]: I failed to make a couple important points about this not 
really 
being an "off-grid" pubnix.  For one, the rpi itself will be powered by 
human effort, but the router it wirelessly connects to will not.  And for 
two, the fact that it rides on the Internet is quite the contrary to the 
concept of "off grid".  It is probably better to refer to it as a 
renewable-energy powered endpoint on the Internet.  If you were to provide 
off-grid power to the rpi *and* the router, then you could create an 
off-grid wireless LAN -- but that's another project altogether.
