It may take away jobs from loyal workers, be less efficient, require an AI subscription, be environmentally devastating, but at least the end product also doesn’t work at all.
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 line (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.
Also a basic rookie 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
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
First thing I noticed is the type c port is backwards
Nothing a little bodge-wiring and a Pi compute-module can’t fix.
Update V2: “Well, my house burned down”
Not too far off from modern GPUs…

Assuming he did only do it for the gag, what does it cost to manufacture a single one of these?
It depends on how many layers there are.
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.
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.
wouldn’t it be D1?
Am I missing it? Or is there not even an LED to light up?
There is, D1 in lower right is an SMD LED
Does D1 have only one leg attached? I don’t see any via hole that connects to the back side of the board.
Yeah, as does the capacitors above it, it’s rather funny
Got it. Thought it was just a regular diode.
I mean…it is.
technically all LEDs are “regular diodes”.
I can see at least one innovation there. Diodes make current go one direction. D1 ensures current goes neither direction.
you know what else achieves the same thing… empty space…
I would love to see the looks on the faces of the Chinese laborers making this stupid thing.
Those kids must have been so upset.
He could have just looked at the schematic before he sent it off to be made…
it’s a demonstration of the amazing capabilities of AI 😂
“I wanted to do it entirely with AI (e.g. blind)”
That’s not as fun
He’s doing it for shits and giggles. He wants it for display.
Yeah I’m wondering what the purpose was for actually having this thing fabricated. What point was he trying to make.
Art, of a sort.
It looks like he was trying to prove that using AI to make things is bad.
I get that, but you could have come to the same conclusion just by looking at the schematics. You don’t need to actually have the thing fabricated to make that point.
Then the point they were trying to make wouldn’t be as strong.
I get it as well, but some people need something a bit more solid to realise just how stupid something is. I haven’t looked at circuits since high school, but if I see something that just straight up doesn’t work, that’s undeniable.
I guess the idea was to get more social media attention this way.
He could have received the same board by having an intern or high school electronics student design it with no oversight.
He also could have sent the result to another AI with the prompt “point out all the errors in this design and tell me if we should have it printed”.
This was just a dumb “hur hur, AI bad stunt”
An unsupervised high school electronics student could easily design a PCB to power a LED via USB power. It’s an extremely easy task to accomplish, which is why it was picked.
Even someone with no training would put the USB port in a better position.
A vibe-designed pcb?
Just wait another month bro I promise it will get better bro (every month for the past 4 years)
Push AI button, don’t check, complain about AI, problem is human
