    I reckon the 'irrigation' is a bad translation for 'current'.

    And anti-current is reverse-current. (Think about it… current and anti-current or opposite current)

    So Anti anti-irrigation makes sense.

    Can the Schottky diode take 74a? I guess the use of MOSFETs is for the large current rating. Make them act like a beefy diode. Theoretically.

    I didn't see any mention of ideal diode in the listing, to be fair…..
    If you go to the hardware store and ask for a shovel, and you're offered a spade with "spade" written on it, would you expect it to be a shovel when you try using it?
    Have you tried using this item to prevent irrigation? It might be very good at that! Maybe try gluing it over the end of your garden hose?

    LOVE your videos Julian. I think, one day, my mind will click into gear, and I will totally understand. Mechanics, I understood from an early age. Electronics; more of a challenge for me. I guess I cannot "see" the electrons flowing. I am getting better at understanding electronics (a lot from your videos) and I was always interested in the subject. Thank you for bringing great content.

    Hmm, ideal diode seems a bit much. Why not just tie a mosfets gate to its source and using the source and the drain as the two terminals of a diode?

    Would make an interesting video to explore, at any rate.

    Edit: Nevermind, it seems this is what this 'ideal diode' is doing anyway xD

    Lol I kept waiting for you to discharge one of those caps, that would have been a shock…

    what do you do with all this stuff?

    1. Hello. I'm here to inquire about your spoons.
    2. Anti-reverse-irrigation might be a bad translation form Chinese.

    I like those (2.1mm?) To two pin adapters, but couldnโ€™t find them on eBay. Whatโ€™s the search term?

  9. Avataaar/Circle Created with python_avatars Adam Bryant says:

    Bah, ha, ha, I made the same mistake when I ordered my JST 1.0 connectors

    This one was hilarious – Thanks, Julian!

    where can i buy PCB feeds please?

  12. Avataaar/Circle Created with python_avatars NightshadeLenar says:

    say…. 603CH is the number your looking for, it is a liner buck controller and a current regulator in one package i beleave.

    trimming all the sprues is half the fun !

    really like that magnifier
