Cabin battery-powered pi5b for local shell and profit
Project
Objective
Finding myself predominantly using my iPad for typing, and cats regularly using my keyboard tray for a bed, ready access to a local Linux box requires work and often has complications. But it doesn’t have to be this way- I have a solar battery bank, which during the summer, typically ends each day at over 90% charge.
Currently I power both my DC refrigerators, and charge my nighttime battery bank, and power my cell/wifi router off the bank, but there’s a whole lot more capacity that can be used. So: why not rig up a pi5b, with all the trimmings, to serve as a 24/7 cabin server? THAT is the point of this endeavour.
Approaches
The way I see it, there are two approaches that I could take:
- from the battery (via the fuse bank) use a buck converter to provide 5V/5A to the pi5b
- invest in one of those pi UPS boards
approach: buck converter
Equipment
