Yes, it is a fail, albeit a subtler one than usual.

Normally you'd tack down only one of the pins at that stage of soldering so either way would work.
. . . if you don't care where pin 1 is!

Forcing a specific orientation for pin 1 is oppressive! 8)

Not exactly a stock image, but I guess government issue might count:

The fence should be designed to avoid a person becoming caught over or against it and unable to remove themselves (mantraps). This is done by design and spacing of fence components - Figure 2 shows fence designs that avoid mantraps. The gap between the security fence and the outer fence should be either less than 200mm or more than 1000mm NOTE: Barbed wire or razor wire must not be used as part of or adjacent to the fences (see below)

Other than that mistake (and the fact that they forgot to delete the two fence supports in the picture on the right). I don't see how the fence on the right would work. If I can climb that outside wall and stand on it, I could easily clear the electrical fence completely by jumping over it. Or have I completely misunderstood the diagram?

They'd probably be in the dark as much as you if they'd thought about it :)

How do electric fences work anyway? Can't you just wear gumboots?

(Or put a plastic sheet on the ground, or jump up onto it, or...)

Electric fences are typically meant to keep animals in or out. Without opposable thumbs, they would have trouble putting on rubber boots or throwing plastic sheets.
Concertina wire is used when the goal is keeping people in or out. People can understand the risk they face of getting sliced to ribbons and bleeding out, animals cannot. Many animals also have thick hides and would not be much bothered by concertina wire.

So electric fences around military bases are just a movie prop?

No, they're there to keep animals out. You really don't want herds of deer wandering across your runway, as a random example

So those fences around prisons are to stop the inmates from making beef burgers? I've learnt something new today.

According to Amazon's YouTube advertisement, it's possible to power a mains lamp, with a couple of potato cells. :palm:

That must be a really "hot" potato! :-DD

Interesting choice of PPE and only one of them wearing it.

More seriously, you can get low-voltage filament style LED lamps, but they certainly require far more power than two potato cells.

You can get low voltage incandescent bulbs too. Maybe there's more potatoes hidden under the table.

It is a 3-phase potato power source, 4 wires on the bench is a giveaway.

Oh you guys, they are cooking the potatoes with main voltage, the lightbulb is the series resistor to lower the amps, unfortunately the potatoes were so wet it was a short, hence the bulb giving light  :-DD

Yes, in fact I was considering joining it, but I'm still on the fence about it.  ::)

There exists a current probe which even can measure current in fiber optic cables.

2287979-0

I am wondering how many kilovolts it takes to force few amperes through them fiber optic cables...

At least it doesn't have a display lit up showing some reading like 90 Amps...  ::)

A humorous Ad would have it clamped around the fiber showing zero current, and the operator with a confused look on their face.  ;D

Double crimp connectors to connect two wires.
But like this it is not going to work
