content: Most of this in this circuit is random and wrong. It's a picture designed to look like a valid circuit, not a valid circuit trying to be depicted as a picture. That makes it smell of LLM/AI.I would recommend to the author that they try and build some simpler linear power regulator circuits off the web before they try to draw any more themselves.60V 30A: nope, that's 1.8kW. The output transistor can't do that (no single-transistor die in linear mode can). The opamp can't handle that (it's 30V max). Everything will blow up instantly.IRFE710: a part that doesn't exist.Second transistor: anonymous stealth aircraft.

Quite stunning.I've already received an email from Farcebook containing false statements to try to get me to look at Farcebook. I've seen large numbers of trolls from AnonymousUser123 and similar.Anybody who thinksanythingon Farcebook can be trusted needs their head examined.

content: You can tell it's AI even without analyzing the circuit because the wire color changes for no reason when the wire goes under another wire.No human would ever do that.Also the notch/arc for the pin1 side of the IC is non-centered which is really odd.I'm kind of surprised the AI would make that mistake given it can't have seen many training examples of that, if any.Actually, you know what, I think the training data probably included schematics that had real photos of ICs and the 3D parallax made the arc/notch appear off-center in 2D.The arc is even off-centered in the right direction to be that.

content: Quote from: PA0PBZ on August 19, 2025, 03:41:03 pmRule of thumb: ignore anything where the "schematic" is really a PCB layout. If the perpetrator either doesn't know the difference or can't be bothered to draw the logic so that it can be understood by others, then it will be a waste of time.That is useful generally; being on Farcebook just emphasises the point.

content: I also lurk, and sometimes post, in other electronic forums which are, to put it mildly, less sophisticated than this one.As sure as the sun will rise again tomorrow, a newbie will write a post with a title along the line of: “HELP! I built circuit XYZ and it doesn’t work. What is wrong with it?”When prompted to provide the schematic, 8 or 9 times out of 10 it will be a “schematic” similar to the one shown above.The sad part is that, they have invested a considerable amount (for their purchasing power) on purchasing the components, and they are adamant to make it work.

content: Too often they can be (mis)guided by similar diagrams on sites that look to be relevant to their needs.If all you see are hammers, you will make nails and nothing else. Or something.If all you see is graffiti, you won't realise how beautiful other artwork can be.

content: These kinds of drawings are a trap designed for beginners. An effective trap must attract as many victims as possible, which is why there are no electronic symbols here. Number of components must be limited. Circuit #1 is more attractive than #9. The circuit doesn't need to work correctly, because beginners won't detect errors before assembly. You can't learn electronics from this, but you can learn the methods used by scammers.
