  • intermittent sounder

    I need a sounder of some sort that will sound briefly once every few
    minutes. It's to remind a van driver that he has the inverter turned on.
    12V.

    Even the most basic 555 circuit will do that fine.

    ISTM much depends on what (if anything) the van driver listens to
    while driving: Motorhead e.g. is likely to require a bit more than a
    smoke alarm's 'beep'.

    I don't suppose he'll be using the inverter while driving.


    Yes, that's a big part of it. They charge their tools as they go from
    one job to the next.
