    >> I think these look awesome .. so tiny ! Thank YOU

    Melanie/Amgen(Don) , please check the updated Capacitive Transformerless AC-DC PSU diagram attached. Common neutral this time (correct me if I am wrong!)

    So now the circuit should be floating 5 Volts ABOVE NEUTRAL and not 5 Volts below LIVE right ?

    Kind regards

    Dennis
    Dennis no its not safe, never never put a fuse in the neutral leg when it is at zero potential to earth. The fuse may blow the appliance looks like it is dead, somebody opens it up touches the phase/neutral, they could be dead. Try a transformer, that way you can sleep at night without worrying about the device killing somebody or smouldering away and catching fire.
    all the best
