    Default Bathtub water level alarm

    Meaning to run an average bath, I've yet again let it fill to the brim.

    So what I need is: a pair of wires, a battery, and a buzzer. So I can hook a simple contraption over the side with the wires pointing downward and ending at the desired water level, and when the water reaches that level the buzzer sounds. Real cutting-edge physics this. (Even better would be a motor that could then automatically turn off the tap!)

    Any ideas where to buy hobbyist type items like this? Obviously I can buy the wire and batteries anywhere, and perhaps the buzzer wouldn't be too hard (I could maybe extract one from a cheap smoke detector for example.) But perusing a good web site might give me other ideas.

    Who knows, next year I could be on Dragon's Den, trying to flog a patent bath level detector.

    Or a stopwatch with an alarm.

    Limited market appeal.

    You are better of flogging it to Lakeland.

    I don't know. Maybe he could do something hooked up to the mains.

    Shocking!

    Get a megaflo system - that way the bath can fill up supersonically in about 30 seconds.

    Or get a smaller bath.

    Use a vertical bath, otherwise known as a shower.

    “Live a good life. If there are gods and they are just, then they will not care how devout you have been, but will welcome you based on the virtues you have lived by. If there are gods, but unjust, then you should not want to worship them. If there are no gods, then you will be gone, but will have lived a noble life that will live on in the memories of your loved ones.”

    ― Marcus Aurelius
