This isn't really a "ghetto PC" mod but I got a good one for you guys.
So everyone knows about Killowatt meters right? I wanted one for my bitcoin farm. They don't work in 240V though, which is what I run my bitcoin miners at for increased efficiency. So I started searching ebay for a "240v watt meter" and after pages of extremely expensive electrical carrier grade stuff, I got this cheapo device shipped to me for very little from China:

Sketchy, right?
I got it. It's rated for 50hz, not the American 60. (It's also rated for 220V not 240). "It probably won't work..." I tell myself, knowing the AC switching hertz are probably cheap chinese crap and hardcoded. I don't care. I wanna try it. I plug it in:
Well I'll be damned! It's happy and keeping really accurate measurements! Who would've thunk it?
I kept it in there for about 6 months, then mining became unprofitable and it sat on a shelf. Today, I got an idea:
"Heck, it took 240V 60hz when it was rated for 220V 50Hz, lets plug it into an american 120V outlet and see what happens"
For the record, this is a horrible idea that should only be attempted by those who have a good breaker box and don't care if they get electric shock and/or start a small fire. You should not willfully violate your devices specifications. You furthermore should not bend the outlet prongs to fit an outlet it is not intended for, like this:
Furthermore, you should never plug it into a live wire if you have done so, like this:
And you certainly should not expect it to be accurate afterwords, like this:
...
Holy shit it is.
China, proving electricity is aparently just electricity...
The funny thing is, this watt meter has PF correction calcualations built it, and is arguably better and more versatile than a killawatt while being nearly half the price WITH SHIPPING.
How'd they make this thing? Did they just stuff it with "do not give a fuck" metering parts and call it a day?
But it's still accurate? Do they actually calculate for this shit?
Why? That has to cost more...
Anyone have a weird voltage or hz rating and wanna try this thing? It's crazy (not as crazy as me for trying this though, admittedly).
Seriously, pick one of these things up. They are awesome. Just don't do any of the things above... that would be unhinged... And also apparently work fine...
PS: I'm not responsible if you blow up for reading this post and trying dumb things. That's my job, not yours. This also has aparently a 10Amp limit, though judging from these tests, I have absolutely no reason to believe any limits printed on the box or product are accurate.
Oh, and for the record, Killawatts
do melt/spark if you plug them into 240V outlets. I know this. Pictures of that aftermath later.
