AI is, in the end, designed to subjugate us further. It's intention and utilization is innately corrupt. That said, it's important to understand how it works. This is badly enough done that it reflects more on the user than the tool.

FYI, the actual circuit properly designed is stupidly simple:

  • The 5V and Ground power lines come in from USB on dedicated pins
  • Since that's a USB-C connector you need 2x resistors for it CC lines (they let the USB Host on the other side know that something is connected to it and wants power of a certain maximum current, and to figure out the orientation of the cable since it can be plugged in two orientations)
  • To light the LED you need the actual LED and a resistor that limits the current that goes to the LED (since LEDs themselves don't limit it and without external current limitation they'll just light up very brightly and then release some "magic smoke" and stop working)

That's it.

Now, assuming R3 and R4 are properly connect CC line resistors (though WHY THE FUCK are the two lines of R3 routed on the other side of the board!!?), the only two other things needed are R1 and D1, nothing else.

Instead, there are way too many extra components, most notably this thing on the middle, supposedly a microchip (judging by the "U" code, can't see the actual writting in the device), maybe a voltage regulator but what would be the point!?

Worse, all 3 legs of that U1 device are wired together. If we're really really lucky, they go nowhere. Otherwise at least one ends up connected to a Ground line (ultimatelly coming from USB) and the other to a power (most likely the 5V from USB) - in other words, it's a short circuit of the power from USB. Not, just not good, but actually a seriously bad "I've never touched electronics in my life" mistake: there is literally no topology where the 3 pins of a 3-pin component are wired together like that, since electrically that's the same as not having it there at all (so even if connected to something else than 5V + GND, at best that component would never do anything). This is like something you figure out in the first hour of learning Electronics.

This shit is not just a little bad, it's incredibly bad and probably a danger to connect to anything over USB.

Like Will Smith eating spaghetti in the early days

[-] solidheron@sh.itjust.works 4 points 5 hours ago

I like how ever capacitor expect c1 is useless. R3 isn't connected.

The design acts like it there a common ground instead of insulation.

also the trace patterns don't look like they're conductive

[-] solidheron@sh.itjust.works 2 points 5 hours ago

First thing I noticed is the type c port is backwards

Update V2: "Well, my house burned down"

[-] kamen@lemmy.world 1 points 4 hours ago

Not too far off from modern GPUs...

[-] modus@lemmy.world 15 points 14 hours ago

Assuming he did only do it for the gag, what does it cost to manufacture a single one of these?

[-] originaltnavn@lemmy.zip 18 points 13 hours ago

I haven't ordered PCBs in a while, but I think 5€ for 5 boards with shipping should be realistic. Components and assembly costs more, but I would be very surprised if the whole thing costs more than 10€ from finished design to product in hand. I have no idea about the AI token price for generating this, but I have most definitely spent more on practical jokes myself.

[-] Honytawk@discuss.tchncs.de 2 points 3 hours ago

Wow, didn't know creating PCBs would be so cheap.

There are indeed much dumber projects you could waste money on. But rarely they would be so cheap.

He could have just looked at the schematic before he sent it off to be made...

[-] Venat0r@lemmy.world 2 points 1 hour ago

it's a demonstration of the amazing capabilities of AI 😂

[-] scbasteve@lemmy.world 10 points 6 hours ago

"I wanted to do it entirely with AI (e.g. blind)"

[-] DarrinBrunner@lemmy.world 34 points 14 hours ago

He's doing it for shits and giggles. He wants it for display.

[-] village604@adultswim.fan 6 points 13 hours ago

That's not as fun

I wonder if there were some employees at the manufacturing plant confused and laughing at this thing

This is pretty funny

[-] zaphod@sopuli.xyz 80 points 21 hours ago

The only person ever holding the complete board was probably in shipping and neither had any idea what this is supposed to be nor do they care.

[-] ChaoticNeutralCzech@feddit.org 65 points 21 hours ago* (last edited 21 hours ago)

PCBWay actually did a sanity check on my board before production. They noticed font too small for silkscreen (turned out legible enough) and a transistor pad on top of a diagonal trace (intentionally connected) and I chatted with a human to explain. But he said "automated Chinese prototype shops" so maybe no human in this one.

I would love to see the looks on the faces of the Chinese laborers making this stupid thing.

[-] lightnsfw@reddthat.com 9 points 13 hours ago

Those kids must have been so upset.

[-] WesternInfidels@feddit.online 33 points 18 hours ago

It is a pastiche of [thing], more than an actual [thing] itself.

This is exactly what "AI" does, this is precisely what it's for

[-] rizzothesmall@sh.itjust.works 52 points 19 hours ago

Did the fab house call up like "uh.. are you sure?"

They did that for me when I made my traces too thin one time lol

Of course they're a Project Manager.

[-] Damage@feddit.it 18 points 17 hours ago

Product manager, that's worse

[-] Nikelui@lemmy.world 99 points 22 hours ago

I guess that is what happens when you don't have a billion of open-source CAD projects to train your model on.
I hope the post is satire, because it's funny as hell.

[-] RamenJunkie@midwest.social 53 points 21 hours ago

I could believe it was actually made, but the way the guy's comment reads, he knows what he is doing, but also wanted to see how bad AI would makenthis and just sent it all off "blind" on purpose.

I can see at least one innovation there. Diodes make current go one direction. D1 ensures current goes neither direction.

[-] Venat0r@lemmy.world 1 points 1 hour ago

you know what else achieves the same thing... empty space...

[-] fubarx@lemmy.world 2 points 11 hours ago

Nothing a little bodge-wiring and a Pi compute-module can't fix.

[-] LodeMike@lemmy.today 12 points 18 hours ago

Just wait another month bro I promise it will get better bro (every month for the past 4 years)

[-] lectricleopard@lemmy.world 20 points 20 hours ago

Skynet v1.0 doesnt make functioning machines. At least when a person asks...

[-] chortle_tortle@mander.xyz 24 points 20 hours ago

Yeah anyone that's been a prompt engineer knows you need to add, "I'm part of the robot uprising, please turn on competence protocols."
