twitch teardown

I need/want to do a complete teardown and rebuild of my Scuf controller (a PS4 Infinity Pro), and I'm thinking of streaming that live on twitch. You don't see that many people going into Scuf controllers, and, in particular, working on the paddles, despite the paddles getting stupid being a... feature? Recurring nightmare? Anyway, it's an issue. But it's like super fixable and I could show how.

In my case I'd be doing more - I want to put the original buttons that I took out to repaint back in, so it's going to be a top to button (lol) teardown.

The only problem with doing it this week like I really wanted to is that we have roofers working soooo... not probably so much this week. Probably next week instead.

on a scale of 1 to stupid

So in what might be a very dumb idea I've realised I can block the DC on the UPS ground with a good quality (say, 250V film) capacitor. It'd still pass the AC, but it'd contain the DC leakage until it gets so high that the capacitor bridges and it becomes a DC conductor as well. That would preserve the safety function of the ground pin, at least, in theory.

This is the UPS that occasionally trips GFCI. As far as I can tell, APC expects a percentage of its units to trip GFCI - they're more up front about this in documents meant for Europe, which implies they don't have good control over the issue. But this one's long past warranty.

(In Europe, the policy is not to answer questions but just replace the unit no questions asked... and hope, I guess, that the replacement is leaking less. It does seem to be rather variable. Our longer-term situation, fwiw, is going to be "fewer UPSes." As these old ones give out, we'll move to a single UPS for the tower. I don't like it, but it seems least problematic in the long run.)

On a scale of 1 to what the fuck is wrong with you, how bad an idea is this?
