  • I’m currently planning for my next server, and there’s the same question.

    My first idea was a plain and simple PSU for 12V and then a small buck converter to make 5V from the 12V.

    Then I found a variant of the 12V PSU that has UPS capability built in (you can plug a 12V battery and it does everything else, or you can leave the battery away and it’s just a PSU) and I ordered me this one. So I need no external UPS unit.

    Example here: https://www.aliexpress.com/item/32852797799.html

    It’s not complete yet. For the wiring I’m going to do some tinkering with a cheap extension cable.













  • It is no paradoxon.

    Only your story is a bit unclear at the point where it matters. Let me ask a question to clarify = to destroy what appears a paradoxon, but isn’t.

    Question:
    Who controls the transmission of the information - the past self or the future self?

    If the past self controls the transmission, then he receives no information. Case closed. It does not matter what the future self is doing.

    If the future self controls the transmission, then he knows when the past self turns off the device. He can send it just a minute further into the past, before the past self turns off the device, and so the past self receives it “in time”.
