My roommate's LED lights went out, and she traced it down to a bad wallwart.

@piggo it's NUDE!

@foone @HoustonDog Oofh, that probably also means a whole lot of foods taste extra bland to you, too. :c

-
@foone that makes sense, it's probably some kind of old paper wax like capacitor...
is it made out of cloth? though, intriguing.
-
@loganer it looks like cloth to me, but I'm sure it's just some kind of paper
-
okay amazingly, she says it never flickered and never actually died: it just got dimmer.
-
so my guess as to what happened:
this cheap cap developed a partially short. It now began passing current through it. This caused it to heat up, boiled the electrolyte, and exploded the can off.
The thing STILL keeps working because now that it's dry, it's a really shit conductor, so only some of the current is going through the sploded-cap, which can no longer boil (and it doesn't get hot enough to ignite). But since some the current is diverted, the lights dim
-
@foone act-of-god your way into a FREE 300 ohm resistor!
-
I would test the resistance (and capacitance) of this exploded cap but I don't have access to my electronic tools at the moment. so into the ewaste bin it goes
-
@parzivalwolfram 300 ohm resistors are cheap anyway if you own wires
-
-
@RueNahcMohr I do, but I can't use it right now. I'm mostly bedridden for medical reasons, so my electronics workshop is unusable
-
@foone did it catch fire

@[email protected] i've worked on several cheap arcade crane machines from a particular manufacturer for some issue or another, often a stuck relay or something thereabouts, only to notice off to the side that one of the caps on the board has done the exact same thing, leaving a small disk of wrapped fabric and a discarded cover we inevitably find ten minutes later
and every single time, the board is still chugging away so we only ever find them when we're already in there for other issues
i think the most i've found was three caps on a single one of those boards that had all done that, and wouldn't you know it the board was still surviving -
@MedeaVanamonde nope! apparently it ran like this for quite a while

@666666t wow!
-
@foone what's the blobby thing that looks like a chicken breast?
-
@yujiri I think that's resin/glue to keep the thin wires of the transformer from getting damaged, or possibly arcing to nearby components
