Are there any cheap Chinese, direct equivalents for these TX & RX modules?

I always struggle understanding those little RF modules as in how to interface them to something "real" like a relay so I've always avoided them. I thought that nutsvolts circuit link really useful. Have you the link again please for those modules you bought?

I know there's loads of fraudsters about and the bit about sticking the probes into lead paint was funny but it came across a bit as saying "it's not damp it's because of the salts in the substrates". There must be cases of damp that just happen too to be "salty" and presumably you'd see higher conductivity than a "dry" salty substrate? I'll hold my hands up to in the past to repairing "breathable" lime plastered walls with a modern, pva laden mix! ? This through ignorance more than anything else. Blocked air bricks was the culprit for underfloor damp on my 1865 first place, a 2 up 2 down terrace. When I did the bathroom just, the inside concrete floor was level with the outside path along the house and the inside floor was itself 6cm higher than the adjacent room floors. The bottom of the cavity was rubble filled too. I took the path up that was bridging the dpc and everything rapidly dried out.

Ideal transmitter and receiver circuits here methinks: https://www.nutsvolts.com/magazine/article/cheap-and-dirty-wireless-remote-control Transmitter constantly transmits and receiver has an LED and relay output. I wonder if those cheap as chips Chinese RF modules @ProDave got from China could be substituted for the Radiometrix modules?

Love it. Got a link to the gravel crates you used?

And it was his was it?

? ?

Here you go Peter, little video of a nice and simple chunky contactor to give you a volt free set of contacts to do "something" if you lose power. Amber beacon in the shed window run off a solar trickle charged battery?

The Please not the one where @pocsterwas kneeling using the UFH pipe tacker...

Yep, no problems, was going to anyway. I'll drill out a couple of arbours, a 10 and a 10.5, maybe 10 and 10.2 if I can find the 10.2! Will aim to post out Monday.

Like the neighbourhood watch did in Sanford? ?

Even the cheapo door bells have multiple tunes. Say Knock Three Times for the doorbell.....

It's when they come out of the bedroom shouting "Look Gran, I'm a unicorn!" it gets awkward...

Right, pm me your address and I'll post after drilling out.

Wedge an eighth in the battery compartment and get an ex police sniffer dog?

Not the slimmest but this sort of thing: https://www.ebay.co.uk/p/3-Remote-Control-Finder-Lost-Handset-Locator-Wireless-Whistle-Beep-Self-Adhesive/2171827369?

Of a pair of these, one went bang pretty soon after purchase. The other, seen here, continues to function: I've been using it to hold formwork together doing the brick pillars. I've kept the broken ones under the illusion (delusion?) I'll take them apart one day in case it's a simple fix! ? Tbf most have screws to disassemble rather than being riveted. This one, the front, then part of the handle/pistol grip broke off in use:

I was only just reading of the high levels of isotopes such as chlorine-36 found in Antarctica caused by fallout from US nuclear tests in the Pacific 70 years ago... ?

Just a few of mine put to good use when I foam filled a upvc cill. It prevented the cill distorting at all. I like the screw handle, G clamp type as you can set them to just lightly "touch" the sides of the pieces you're clamping without squeezing in any way but still preventing movement. The orange "silicone gun" type, along with the Irwin esque types I suspect apply a constant force until released.

I can see how this bloke's neighbours might have complained and the council coming down on him: https://www.pistonheads.com/gassing/topic.asp?t=1469925

What Geberit WCs are you having, the Aquaclean ones that wash and dry your ar5e?

He exists on this very forum, just say his name three times!

I've a selection of this type collected over the years, varying in size and quality. Can't tbh remember the last time I used them!
