More on the evil UPS

[solarbird]

Insane UPS update:

Moving the ground coil away from the inductor coil (and also uncoiling it) helped... but only a little. A couple of milliamps and maybe like six volts? So I implemented my DC blocker with a bypass if it gets high enough voltage DC and tried it again, DC no more issues, AC reduced issues, plugged it into a GFCI...

...and it tripped in like an hour.

So I think I'm just done trying to make this GFCI-compatible.

I'm trying to figure out now what to do with this stupid thing - whether to keep it as a parts UPS, or what. I guess I could use it on a non-GFCI circuit, maybe for... idk, chonkyboi, my gaming PC? Maybe I'll do that.

I think you might need to block the magnetic fields from the coil, which is difficult. Is it possible to wrap the inductor and the ground coil with pieces of iron or nickel (maybe cut up a food can to get thin and flexible steel)? That would only attenuate the magnetic field, though, not block it.

I thought about that. But I also kind of thought, "Y'know what? I'm 99% at this point on this being within design spec, and I just don't know enough to fix it, so fuck this thing."

How strange and frustrating.

Insanity-making, no lie.

I wish I knew more about electrics for real.
