thx Don
we've all had those "learning" experiences, haven't we?

Like when I absent-mindedly started soldering a board in my SH-2000 with the mains still on....

Made me chuckle, Adam.  Glad you lived to tell the tale though! :-)

Every day is a learning day in electronics.

Failures and blow-ups are the best teachers! There is wisdom gained in 
every puff of magic smoke.

I've created light emitting resistors, launched electrolytic caps into 
low Earth orbit, blew the lids off of ICs - here we are!

I wired up the transformer in an 1176 build the wrong way. I thought
the smell was it just warming up... well it warmed up all right.

I'll bet the transformer made a wonderful harmonic rich buzz before that 
poor bridge rectifier blew.

Reversed -15V and Gnd once. Blew all of the 4136s but the 741 survived.

Then there was the line extender famous for melting the magnet wire in an expensive square wave transformer. Some genius put the fuze AFTER the bridge.

You can’t blame myself for that design mistake. I can’t remember if it was Sylvania or Scientific Atlanta.  8D

I haven't heard any buzz because the blast was immediately after 
powering it up.

So far, nobody has mentioned AI...

As soon as I saw "Vibe Circuit Design" on the subject line, I assumed that this was a reference to "Vibe Coding" - which lets an AI try its hand at writing code. Thus, I figured that the red-hot component was the result of allowing an AI to design a schematic without a human reviewing it for obvious mistakes.

What's the background context for this, Don?

Exactly as you said.

"Vibe Coding" is using one of the modern AI platforms to write your code.  Sometimes there are errors.  "Vibe Circuit Design" is the electronic equivalent.  And sometimes there are errors.  And unlike software, errors can cause electronic circuits to burst into flames.

Recall the discussion here back in September where there was a question about whether an obscure I2L chip clocked on the rising or fall edge of the clock pulse.  I analyzed the circuit and said the falling edge, while Grok and ChatGPT both said the rising edge, and GoogleAI just gave up.

There is so much AI BS on facebook, that I block them all. It's so 
irritating that I cannot even laugh at them, although I think the 
intention was for them to be funny. The circuit is always drawn with 
nice graphics and actual component look instead of symbols, and 
ridiculous errors everywhere. The worst part is that judging by the 
comments lots of people fall for it.

Paging Harry Bissel and his stories. I seem to recall that he did heavy duty testing of industrial strength equipment with equally spectacular failures.
