Wow you guys are super sleuths!  That's part of the fun!

It simply makes sense to put the "nasty and dangerous" AC inputs on the far end of the terminal block setup.  Then you can "play" with the 5-volt output pins in the center.

So I was right in my first assumption.  So you are now officially in Whackadoo Land with Mr. Akua wiring up the DC out to one side of a transformer.  He was just getting cocky and lazy, just like the fact that he couldn't be bothered trying to hide the fact that he broke the seal on the power supply in the first place.

I also see some videos have been made private.  I don't know whose videos they are but that's the classic pattern.  Mr. Chicken Head makes a fake clip or clips, then he stumbles and before you know it his video clips start popping out of existence.

I bet you he hates his mother!  lol

@ MH
there is latest Akula's video:

Yep. But consider this.

If the power supply is not altered, and if I am right about the pinout, the DC output could still maybe have an effect on the transformer by biasing the core. So if the input (black wires) to the PSU are getting some kind of low frequency oscillating signal from the Mystery board, this could be.... maybe.... modulating the DC output in some way that then affected the core's permeability and thus the inductance and power transfer characteristics of the other side's windings that are connected to the board.

Or there are batteries and some switching logic in the altered PSU.

But also.... How does that DC power supply respond to having its output short-circuited? Some will just fold back and not produce any output; others will try to maintain constant current by dropping the voltage to near zero; mine in the video will overload and pop the circuit breaker, hopefully before the magic smoke leaks out....

@ TK
you talking about old issue. Akula made self runner without PSU.
check latest his video:

Tysb3,

I tried the first video link and did not see a video window and a play button.  I will pass.  The less time I spend on an unknown Russian web site the better.  I am very wary (осторожный) about Russian web sites.

TK,

Who really knows.  I am pretty sure that a switching power supply is just a pulsing inductor charging an output cap (Bedini strikes again) with a voltage sense that feeds back to control how much you pulse the inductor.  So the guts don't lend themselves to any kind of rippling on the output because there is some rippling on the input.  I think.

Notice that a switching power supply is not a "true" power supply that will sink current to keep the output at the desired voltage if the "load" is trying to over-voltage the output.  The voltage sense will just see that the output is already "high enough" and stop switching altogether.

At least that is what I infer because as you know I stopped my true electronics "nerding" before the PCI bus came out.
