water leak alarm

How about just fixing the washing machine.

Hi Robert,

I've been looking for something similar for a while. See the link in this post:

I'd have thought that the batteries would only be used when the detector detects. There are cheap diy versions available with a clothes peg and an alka seltzer :-)

If you are any good at soldering Rapid Electronics do a pretty basic kit:

Alternatively, if this doesn't work the googling "rapid electronics water detector" goes straight to the page you need.

And its cheap!

No connection with Rapid, but I've always found them to be fast and efficient

Not necessarily. Water isn't a good enough conductor to just put two wires near each other, with a battery and a buzzer, and call it a water detector. There will have to be some (probably very simple) electronics involved, which will draw a little bit of current all the time. Very, very small, though.

Well, that certainly uses no power most of the time. I reckon eventually the tablet might break down through age (perhaps from absorbing moisture from the air) - but then again, one could call that a fail-safe mechanism. At least it alerts you when it needs attention, rather than just dying of flat batteries.

Heh. Some interesting items there. Forgive me if I don't trust their £25 "safe" for anything worth more than the box itself :-)

And what on earth is this thing:

The message from Pete Verdon contains these words:

Aw, C'mon.

Fireproof safe? Well, I don't need one. I've got a genuine Chubb fireproof filing cabinet that cost a few thousand. But at £25 to protect a few documents? They'd stand a reasonable chance in the average house fire and it's a whole lot better than nothing.

Lidl stuff is a mixed bag, but at least they stand by it a whole lot better than most other companies.

Thats one bit of tronics thats trivial to design so that it eats no current until it detects. In fact water detectors are one of the simplest electronic things to make, even with no soldering iron its not difficult.
