NEMA 6-15 plug to NEMA 5-15 socket adapter.
I see no possible way this could go wrong.

A while back I got a new digital 'scope. The one I'd been using was okay, but only 8-bit and had some other limitations. The vertical resolution was actually starting to make it difficult to get accurate-enough readings of some things I was working with.
The new one is 12-bit. That is likely to be better than I will ever need. I'm happy with it. Being several years newer (and a different brand) it brings some new #features to the table.
One is that you can use it as a digital logic analyzer - it can sample a whole lot of inputs (rather than just 4 analog channels) quickly if it only has to tell on from off. But you have to get a whole lot of #signals into the #scope before you can do that, so you need a #connector with a lot of pins/signals.
You could use something standard for this type of application (which is still going to be a limited-audience part), or a custom thing, but those options are expensive. So instead, if you're the manufacturer, you find a common (and therefore #cheap) #connector with lots of #pins, and you re-use that. Done and dusted!
They picked ... the HDMI connector. It's there at the bottom of the middle of the control panel. And in the manual is the prominent (not) warning:
> WARNING: Non-standard HDMI interface, Siglent device ONLY, or you will damage your device.
Yes, if you plug anything HDMI-related into this obvious #HDMI port, you will cause damage to your 'scope, or your other device.

welp something sure disintegrated itself
that's F501 next to it and i can just make out F50-something under the ashes
F is fuse
fuse go kablooey
which means something else is still shorted
fun
the mobo isn't short anymore so the problem gotta be on this itty bitty power supply
-
why is posting photos so slooooow is the internet melting down
got this Compaq LTE 386s/20 as a repair challenge, would be perfect to run Citadel-86
power brick appears to work, 30v on two pins
plug it in to the laptop, the light flashes and you can hear it start and shut down, oh yeah that's a short
lets get it apart
sum magic smoke let out by the battery

So I had - past tense - one of those cheap but incredibly useful and surprisingly capable MCU-based component testers. You know the ones - they cost about twenty bucks, can identify virtually any 2- or 3-terminal device you stick in their (usually ZIF) socket, as well as telling you things like which leads are gate/source/drain, base/collector/emitter, anode/cathode, or whatever else you might want to know about a lot of electronic components.
Absent-mindedly put an electrolytic capacitor into it tonight without discharging it. Had about 22 volts in it... hence, one ex-tester. I let the magic smoke out, without actually releasing any smoke or smell.
Oops.

YW 😉
Indeed, connecting something labelled "NC" to ... well, anything ... will, under ideal conditions, do nothing. Under more realistic conditions you can expect misbehaviour or worse, up to and including releasing the magic smoke in a violent manner.
If the manufacturer wants you to tie unused pins to ground, or Vcc, or something else, they'll tell you explicitly in the datasheet. They definitely won't label them "NC" ... in a correct datasheet, anyways.

Okay Mastodon let's see if you can help.
I have this TPS560430 DC/DC buck which now has blown up twice on similar boards.In both cases the failure occurred when plugging in to a live 24V 2A source. It appears the DC/DC has some kind of latch up and catches fire. Downstream of the buck is a TVS which is used for protecting some I/O ports, an STM32 and a few bits and pieces.
For a temporary workaround I've placed a 100R resistor between the 24V supply and the TPS560430, but I'm not sure of the cause and whether this resistor would help. It's also going to affect stability of the buck especially under load.
Anyone have an idea where I'm going wrong?

No, I didn't solder a very clearly marked polarized electrolytic capacitor backwards across the power rails of my project board tonight, causing it to smell funny, emit a loud POP, and spit its guts across the room.
Not that you can prove, anyway.

Measuring the characteristics of some cheap J113 / 2SJ113 n-channel JFETs I bought, so I can match them / divvy them into bins.
Put #15 of 20 into the JFET test circuit, and the power supply's current limiter kicks in ... whoops. Did I have it turned around so I swapped the terminals? Nope...
Take a peek at it. Slightly different marking. Still "J113", but the factory/date code is different. Put it in the component tester... it's a PNP BJT transistor, not a JFET at all, and with a pinout completely unsuitable for the JFET test circuit. If it had been in for more than a second, it probably would have let the Magic Smoke out.
Oh, #AliExpress sellers, where would #hobbyist #electronics people be without you? Somewhere with less excitement in their lives, I guess.

Oh my $DEITY, the "AI" #slop problem...
I do #hobby #electronics. I ran into a problem that I was having difficulty figuring out from the IC manufacturer's datasheet (which is terse, but does contain several example uses / circuits). It felt like I was missing something fundamental about the way it worked, so I searched the web for 3rd-party documentation, tips, tricks, examples of use, etc.
And I got pages and pages and pages of results that were nothing but slop.
Language clearly stolen from the official datasheet and reworded by #AI into not making sense.
Articles that repeat the same point in multiple sentences in multiple sequential paragraphs.
Descriptions that refer to numbered components that do not appear on the shown schematic.
Descriptions of the working of the component that are incredibly obviously incorrect, to the point that anyone who's ever measured the voltage drop across a resistor would say "That can't be right".
Confident declarations of the function of many of the device's (numerous) control pins, which are not only wrong, but sometimes completely the opposite of reality. To the point that if you followed the given instructions, you would very quickly release the #magic #smoke and become sad.
Out of the first ~60 #search results, I saw 2 that were actual humans communicating. And neither of them had a solution, they were only semi-related.
The #web is #broken. Thanks, #SiliconValley #techbros.

The #powersupply seems dead. I have other two, so I tried them. One was dead (as written, in italian, on the label), and one turned on the computer but no "bong" from the speaker. And the fan seemed a little more noisy than I remembered, so I checked the voltages and... holy cow 20v! I immediately disconnected it, hope not to have caused further damage. There was no #magicsmoke, only some fishy smell typical of the #capacitors #electrolyte. Not surprising, considered they have leaked. -

Hier mein Beitrag zur Fotochallenge von @norberteder
Es handelt sich um den durchgebrannten DC-Converter der Theben Zeitschaltuhr eines Terrariums, dessen Beschriftung mit blossem Auge nicht erkennbar war. Um ihn ersetzen zu können musste ich ein Makro davon machen. Dies hier ist mein erstes ernstzunehmendes Makro gewesen. Der Chip ist etwa 2-3mm breit. Aufgenommen mit Sony A6500, Kitobjektiv und Makroring 16mm.

Ahh, exactly 11 months after I purchased a Power colour AMD 7800XT it died. All the outputs failed, but it is still recognized by my system and can render stuff.
So weird, changed slots, changed power connectors. Fans spin up, LEDs turn on, both Windows and Linux see it - but nothing connected to it.
I've submitted an RMA, hopefully it won't take too longer to get it fixed. But, seriously?

Vielleicht sollte man nicht denken: ja, ich habe doch mal #Physik studiert, das läuft schon so mit einer halben Hirnwindung. ... 🤔 🤣 🤣Konkret: wenn man die Heck-Blinkerleuchten von 21 Watt Glühlampen durch eine #LED-Leuchte ersetzt, dann erkennt das Bimetall-Blinkrelais des #2CV die (funktionierende) Lampe nicht mehr. ...
Das sollte man doch mit einem kleinen Widerstand korrigieren können. ...
P = U * I, also ist I = 1,75 A.
U = R * I, also muss R etwa 6 bis 7 Ohm sein. ...Den Rest erzähle ich dann lieber nicht mehr 🤦♂️ , oder nur noch in Hashtags: #VersuchMachtKluch #MagicSmoke #BlueSmoke #KirchhoffscheRegeln

@isziaui @bleeptrack: Hey, cool, two other #CityEL owners in the Fediverse!
Here's mine, nicknamed "ObriEL" and old enough to be born as #MiniEl.
Unfortunately the #magicsmoke came out when I tried to figure out why it doesn't charge. 😒 (Took it over without documentation on any of the modifications from the legacy of a late friend, @Obri, hence also its nickname. So in case anyone knows CityEL repair shops in Switzerland accepting CityELs of unknown state…)
