Yeah this one will do it:




Looks like part of a Megavolt inverter. @VK5RC: You'll usually find them somewhere close to an underwater DC connection between countries. You might need a decent trailer to get it home though. Maybe something like this?

I want one of those 'small' trucks as well.
I showed my wife the picture of the transformer and that I wanted one and she said 'yes dear'!
What a gem!

Actually Edison should be the proud one, he was the one that said DC is the way to go.

On a slightly more serious note, a few years ago I was fault tracing an old hp system power supply which upon 1st 'enable' the over voltage would trigger - turned out to be a missing output filter capacitor (probably from when it was built as no sign of rework) - very easy to miss as the pcb covers about 5 models and only about 3/4 of the pcb is populated and the schematic also covers multiple models and many of the components on the schematic 'aren't there'!
The unit has two internal supplies - one ground referenced for the control / digital circuit and the other floating for the output. Having nearly fried my scope with a probe ground connection f-up, I was thinking of putting a small fuse in the ground wire. Instead I now leave the ground wire disconnected, with a red piece of paper (warning) in the ground clip.
I haven't seen a fuse like that , and thought it shouldn't stuff up measurements too much.
Certainly much better than a long ground clip lead would.

What do you guys think?

I know that i shouldn't do it, but dmms have fuses!

It annoys me that these are being called transformers. It's not a transformer, it's an inverter.

Good to know, but unfortunately, the solder joints are fine. I should have mentioned the attenuators. They were horribly burned. Probably absorbed most of the energy.

Talking of "horribly burned" - remember last week's blown fuse? This is one of the DUTs.

Whoops.

That reminds me of the "we had a small fire in the DC when the A/C blew up" I saw a few years back. 6x HP servers had sucked that crap from one of the redundant UPS's that blew up and deposited it all over the insides until they blew up.

You know it's a bad day when the first diagnostic tool you need is a shovel.

Yeah, but how do you get the residue to be blue?
Anybody got a syringe I can use to squeeze the magic smoke back into this?

Yea, you're right. Tesla did originally work for Edison but when he asked Edison for payment for services Edison refused. So he quit and went to work for Westinghouse.

Interesting tidbit: Up until very recently there were several elevators in lower Manhattan that still had DC motors driving them.

Another tidbit: The power company that serves the NYC metro area is called "Consolidated Edison" or "Con Ed" for short.

That name would fit our local metro nicely too. When you travel 500 yards and it costs you €2.20 you definitely feel Con(n)Ed.

Off topic, but I posted the other day about a watch I had ordered from Wish.com, it was a copy of a Citizen Blue Angels watch, which is the same as the Red Arrows version that I already have.



It arrived today, very impressive seeing as it was only ordered on the 11th and 8 days later delivered and placed in my hand  :-+ and on opening it up (it was very well protected for the journey I might add) it was not as per the photograph that I ordered against and as I had suspected, never had all the features that they claimed, ecodrive, sapphire crystal glass, and I could go on but I won't, but here is a photo what I received today and what the original (Red Arrows version) looks like.



As you can see there are many differences even with the photo used in the original advert on Wish.com site.

I raised a complaint on line this morning, explained my complaint that it was an obvious fake although I did know it was before I ordered it, I attached a copy of the bottom photo to show it was not like the genuine item, and I got an immediate refund in full and no mention of returning the fake item to them either, so I've gained a cheap fake that looks good enough to wear even when going decorating.

Overall, pretty good result, though I doubt the watch will last long.  :-DD :-+

So you knew it was a fake before you bought it.

You received it knowing it was a fake and then raised a stink that it was fake.

They refunded your money and you get to keep it.....knowing it's a fake.

Pretty slick I'd say, I'll have to try that with the cheap Chinese stuff. I could have a house full of knock offs in no time.  :P :-DD

You willingly order a fake, are happy with it but ask a refund?

Yep, afraid so, guilty as charged. The give away apart from the price, is the word Quartz under the Citizen logo and the fact that there was no left-hand winder to operate the rotating slide rule, otherwise the watch was certainly good enough to fool most people who did not know much about watches. Hence, I thought, give it a go, good enough to wear all the time and not have to worry about damaging the real article which is around £300 new and the fake, just £17  :-DD :-DD

Yes, because it was not like the top photo, look at the photo again and the Red Arrows watch, they are really close apart from missing left-hand winder for the slide rule and the word Eco-Drive" replaced with the word "Quartz"

What was it? 9 or 15 quid or something? I'd say it's everything you could reasonably expect.
