@huronbikes I personally wouldn't even care if it weren't for all the malware. How they spend their time is between them, their manager, and HR.

@pluralistic The most under-reported uBlock protip I know about is checking off the the "annoyances" filter lists after installing (which are not checked by default)!

The Register

A viewer sent me an email, asking me to look over a schematic for an autofire circuit that he had a generative AI create for him.

This is the circuit he sent me.

It doesn’t make any sense.

I sent him a circuit that works from an old magazine I used before.

Don’t fricking trust AI with anything.

Simon Zerafa Jul 23

I'm not entirely sure what the circuit would actually do.

Possibly open a portal to the netherworld? 😂🤦‍♂️

@simonzerafa Maybe it is the flux capacitor we were looking for all these years!

Simon Zerafa Jul 23

Oh I don't know that's a good idea.

There is enough idiocy in this timeline without exporting or importing more from other ones 🙄🤦‍♂️

(Also, not sure what the actual netherworld portal circuit would look like but I’m 100% certain that it does use a 555!)

sebastian Jul 23

@janbeta These days everybody uses an Arduino in their netherworld circuit. That's really inefficient if you could just use the 555 instead.

Also that schematic breaks my brain... I can't even.

@sebastian I‘m sure a 555 can be tuned to the correct frequency for opening the portal. The only thing I’m missing to complete the circuit is that 10nF diode.

Dr David Mills Jul 24

@janbeta @sebastian don't knock the 555, I booted Linux on one recently.

@dtl @janbeta Uff...

eighthourlunch Jul 23

@janbeta Only one? I soldiered all of the 555's I own end to end like ants on parade. I plan on using them as a rope to lower me down. Not sure if it'll be long enough.

Stefan Baur 7 * 💉Jul 23

@janbeta Humbug, no netherworld portal is complete if it doesn't have nixie tubes! 🤪

B-TR3E Jul 24

@simonzerafa @janbeta Resetting a 555 timer IC and never let the reset pin go. Also providing a lot of pointless attempts to produce something that looks like a pull-up circuit but isn't.

Tony Hoyle Jul 23

@janbeta The more you look at it the crazier it gets..

@tony Indeed. 😅

@janbeta
I don't think they make 10nF diodes or one-legged 1k resistors any more...

...or ever.

Gonna have to source and strip down a parts 'topsy-turvy nonsense board'.

@smbsy Somebody has to invent those components! Maybe the circuit works after all!!

Smbsy Jul 23

@janbeta I think I can start research and development on the resistor right away. I have some wire cutters around here somewhere...

Richardus Jul 23

@janbeta If he would have donme a search on normal 555 pulse generator he would have found better schematics.

@1024Bytes Most definitely. He also could have looked up NE555 autofire circuits in a regular web search. There’s quite a few out there that actually work. :D

Workshopshed Jul 23

@janbeta the more you look the worse it gets

@Workshopshed Very much! 😅

Ret Jul 23

@janbeta “fire” yep that bit is right

@ret I think it wouldn’t even do that if you actually built it though. 😅

@janbeta I'm losing my will to live looking at this circuit. This is a crime against human dignity

@janbeta
(Un)surprisingly AI is very good at lying 😁 That's also been my experience. Every AI model can come up with an answer and all of them can be totally wrong. It's hard for the user to know which AI model to trust (and yes, in critical fields don't trust AI at all, always verify the answers).

@amarok Why use an AI in the first place if you have to verify the answers (or know enough to answer the question yourself) anyway? 🙃

I am Jack's Found 404 Jul 23

@janbeta @amarok

Most people just don't care... They tick the box and move on to the next half assed task...

You've heard of technical debt... This is the beginning of exponentially compounding technical debt...

A very high APR line of credit that soon becomes a toxic asset. Will the market absorb them safely? That we'll see it in the next episode... 🙃

Chip Jul 23

@janbeta That’s outstanding. What a train wreck of a schematic. 😂

atapi ❤️Jul 23

this schematic must go pretty hard if you know literally nothing about electrical engineering

Elias Mårtenson Jul 23

@sterophonick @janbeta you just wait. Vibe circuit design might just be a thing. 😃

🇳𝗮ꜟ𝖼𝘩 Jul 23

@janbeta
Anyone know where I can get a 10 nF diode?

ᴊᴏʟʟʏ ᴍɴᴇᴍᴏɴɪᴄ Jul 23

@Naich @janbeta Fun fact: You CAN use a reverse biased diode as a (variable) capacitor but they tend to be in the picofarad range.

Look for "varicap diodes"

DG5DBH Jul 23

@Naich @janbeta at the same suplier as for.1n4148 transistors.

🇳𝗮ꜟ𝖼𝘩 Jul 23

@HolgerMBGL @janbeta
Well, there are 2 diodes in a transistor. Not like that though.

wyatt Jul 23

@janbeta ah yes the famous "1K" and "3" pins of the 555
and the diode-as-10nF-capacitor to pin 1 (which is different from "gnd")

All those disconnected components, lol. And the d-sub only having 8 pins. and the fire button being on the top row. and… (etc)

Lasse Beyer Jul 23

@janbeta fuck 🙈! A 555 with two reset pins is a 666; and what's a DE-9 with two pins 8?

Full Metal Archaeopteryx 3d ago

@lasse
Those are the infinity pins; get four more and you do anything you want

@janbeta
In the parts bin the elderly amputee components were sharing their war stories.
--"A nearby bulk cap blew off my anode leg!" said a rectifier diode.
--"An 800 degree soldering iron took mine... bad ground plane thermal relief."
--"I sat in a DIP socket near a Varta... lost six legs." said a DRAM.
--"Oouch! Hmm.. and what about you two, resistor and transistor? How did you lose your legs?"
The two just stayed silent and bowed their packages in shame.

Catcrimes Jul 23

@janbeta Ah, yes, pin 8 and its neighbour pin 8.

edit: oh god, I didn't even see the 10nF diode at first!

Matti J.Jul 23

@janbeta As somebody recently said here on Mastodon, the AI will produce 'an answer-shaped object' rather than an actual solution to _any_ problem. This is an interesting example. Drawing a circuit requires that you actually know how the components work. Here, the training data didn't include enough circuits out of which to synthesise an answer-shaped object good enough to fool us into thinking that the AI knows what it is doing. Thanks for sharing!

Miner34 Jul 23

@mattijamsa @janbeta They should train AI to say that it doesn't know something well rather than lying.

Robee? Na! 🌈Jul 23

@janbeta A floating resistor and base, and the famous Atari infinity pins!

Eli the Bearded Jul 23

Are two pins numbered "8" or is that some @NanoRaptor DE with doubled pins?

tekhedd Jul 23

@janbeta Holy crap this is wonderful. What do the numbers on the DE-9 (that very common 8-pin DE-9 that we all know and love) connector even mean?

My last experience with circuits was an engineering physics course a long time ago, which didn't get super deep into it and I've forgotten almost all of it.

I can still see that this is completely fucking cursed.
