  • Damn, made me chuckle

    Anyways, going by

    , i have had multiple people (2, which is not a lot but it’s weird it happened more then once) say that they couldnt solder just to discover that they were using their soldering iron wrong.

    When you press the solder against the iron’s tip, it should get wicked by the tip, and remain there until you press it on some wire/component leads.

    If the solder beads up and slips away from the iron, or beads up and forms a blob at the end of the solder wire, it’s oxidised and you probably need to get a new tip. It needs to be shiny and metallic.

    The tip needs to be regularely cleaned while soldering by brushing it on a wet sponge, and never let the iron cool down without some solder on the tip to prevent oxidation.

  • a fun fact about this, by the way

    the reason we scavenge steel from old shipwrecks is because all modern peoduced steel is contaminated with a miniscule - but still present - amount of radioactive isotopes, incompatible with some incredibly precise scientific instruments and other nieche, but essential applications, that not only require old steel, but old steel that wasn’t exposed to all the radioactive fallout during the nuclear tests in the cold war, hence why the sunken ships.

    adding a personal note here, if some nuclear tests around the world contaminated everything THIS MUCH, what will we say about microplastics in a couple decades? just food for thought
