#MagicSmoke

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.

#JournalEverything DIY bike shed alarm update: I've been chewing this over for a few days now. I didn't post about it at the time, because I was still processing it.

I was busy hooking the updated ESP32-based external alarm panel electronics up on Saturday night, in fact I was nearly done, and as I was working I noticed a "hot electronics" smell. No #MagicSmoke but a definite "hot" smell. Using my built-in temperature sensor (aka index finger) I traced this to the actual S2-mini ESP32 board. And it was hot enough to make me recoil. #BadNews .

I disconnected the power - both the battery backup and the DC feed and bailed. It was dark and I was well overstimulated from trying to get everything wired together properly in the cramped space of the enclosure box.

So I've been mulling this over "on the backburner" (i.e. subconsciously) ever since. I hadn't reached any conclusions yet, so I let it sit there.

This morning, I have some ideas/theories. Will be investigating further:

1. The piezo sounder could be drawing too much current. It was sounding constantly from the time I hooked up the backup battery.

2. The tone() call I'm using to drive could be too CPU intensive.

3. The #ESPNOW radio comms is somehow causing the heat - perhaps winding the output power up really high because it was getting no response from its peer, which was switched off at the time. I don't know how much, if any, handshaking ESPNOW does.

4. Something else electronic is drawing too much current through the onboard voltage regulator or similar.

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.

Damnit! My original powerbook duo power supply just made the #magicsmoke while I was getting my duo setup for action today. Glad I was able to yank the cord quickly! #marchintosh

From the looks of it, this Ikea Drill has either loose wire or something. All I know is that is could potentially be a fire hazard.... fun.

I mean, I like it when a fire is lit in #Winter but why does it have to start in my WiFi power plug ? #diy #magicsmoke #iot #safety

#52wochenfotochallenge #klein

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.

Oops!
I found out what happens when I connect the wrong battery charger to a lithium battery.

#MagicSmoke

A postage stamp sized circuit board, it has a USB socket on the left, a chip and some surface mount components on the board, and red and black wires on the right.
The chip is overheated, melting through the heatshrink sleeving that was over the board, and some of the components have melted off, too.
There is burning and discolouration on the board.

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?

Well, 20 years ago I built this 24kJ capacitor bank and blew a ton of shit up. Like this tater. Good times. #electricity #highvoltage #magicsmoke #boom #fire #explode

Oops, just blew up the PMIC on a Raspberry Pi CM4

There was a surprising amount of magic smoke in this little fella.

But I'm more interested in how I managed to blow this thing up. Rated for 12vdc, applied 12vdc, poof! My only guess is that the LED driver HAS to be driving something when powered on (I did not have the LED backlight connected when I first applied power).

Can't quite figure out what this part is, either. There's a similar IC marked GJL and I can find that one (AP3032KTR LED driver, if you're curious) but the damaged IC is marked **AB and I don't think that's enough to go on.

#Elektrotechnik 😱

Tja, ...
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
#Maschenregel #Knotenregel #Spannungsteiler #Nennleistung

Ja gut, irgendwo müssen die 21W Wärme ja auch hin.
Vielleicht brauche ich doch das passende elektronische Relais dazu. Und einen Blinkersummer, ...
