Anyone have any idea as to where to find iron, be that in nails, rods, sheets, bars, ect..
TLDR: Trying to build a rotor core for a DIY shunt DC motor but have no clue what to wrap armature coils around that retain any smudges of magnetic permeability
It appears that hardware stores only now sell steel/composite alloy for construction,
I just have no idea where to find ferromagnetic iron

I'm fucking pissed. A renter, who I explicitly told repeatedly "if the water pump runs continuously, for longer than 3 seconds at most, unplug it and tell me". And of course, what happens? I come home and find a note on my door that the pump is turning on and off, he couldn't figure out how to turn it off, and that he's leaving for a while.
I go over, its fucking rapidly cycling, pulling air, very hot, etc. The intake line is fucked up for various relatively predictable, but nonetheless unlikely reasons. I knew he wasn't paying attention worth shit and half saw this coming, but come on. Haven't tested the pump further yet, don't know if it's alright.
The point of this post. I need to find a pressure gauge that either be programmed to output a signal at certain ranges, or constantly outputs its reading. I can have something cut the power to the pump at the outlet when it drops under 5 psi.
Is this a thing, or am I going to have to make it myself? Assuming I still have a functioning otherwise brand new pump. "Please fix, thanks."
