Excellent writeup this is going to be a huge help. I think I'm going to build a pair of 12v fat 50 cans and a larger 40mm can with a number of batteries once i have more experience. I think I will go with the cigarette lighter port and the various adapters with usb power as most of the devices including my ham setup can be powered off of those options. This seems like a good winter weekend project.

I can definitly write up an article about 3d printing and computers. I will reach out to you on the contact form to talk specifics.

@Norton's Ammo Bench Same. Fortunately I have enough experience to muddle my way through. Just finished the tear out on the ceiling of the basement to expose most of the plumbing and wiring. I don't know who wired this place but its like they were begging for a fire. But the good news is 3 of my neighbors were flying Gadsden flags below the stars and stripes this spring. Turns out 2 are fellow preppers. This neighborhood keeps getting better.

Got a portable generator dropped off at my place mid December last year. Problem is the wiring in my old place is such a mess I cant isolate the emergency circuits. Looks like were going to have to begin the rewiring process sooner than expected. At least with the well pump and boiler.
