Building a DIY defibrillator in an emergency,
Psi:
As a last resort, after CPR has been given for 30min, you might as well try and shock them.
At that point they are dead anyway and you have nothing left to lose.
Given that help is 12 hours away and both the people are now too exhausted from CPR to continue and continuing after 30 min is pointless anyway.)
No one is suggesting a DIY defibrillator is a good idea, except as a last resort before giving up.
The thread was only an engineering thought experiment.
SiliconWizard:
If you are concerned about that case possibly happening and have had ample time to think about it, just buy an AED and put it in a safe, yet accessible place.

Absolutely agree.
But this thread was an engineering thought experiment on building one when you don't have one.
You can all rest easy that I have no desire, or need, to build one 'just in case'.
For any situation with knowledge ahead of time that one might be needed it would be moronic to build it when you can buy a proper one.
SiliconWizard:
I think our words of caution were more aimed at random people possibly reading this thread rather than you in particular. In public forums, you never know who's gonna read what. (And now, what is going to end up in a AI model. :palm: )
Anyway, technically speaking - and not meant as advertising for AD, but purely to give some ideas about how an AED is designed, you can have a look at this:

What about the case where one is trying to save a pet rather than a person? That might make things easier as the smaller size means a lower voltage.
