Somebody asked recently about a stud finder, don't know if this is of
interest:

Price is ludicrous.

That seems to be a thing where instead of beeping to say it found a wooden
stud, it shows a picture of a wooden stud instead. Looks like a bit of
accelerometer trickery to show you 'where' it is by inertial tracking.

Holding both the unit and the phone in different hands seems like terrible
ergonomics :)

I'm waiting for the AI-powered version with 3D rendering of the studs,
and showing if that T&E is red/black or blue/brown ...

The picture at the bottom of this article, is a match for the item.
Presumably the company provided some "input" for the article.

https://en.wikipedia.org/wiki/Stud_finder

"A 3D imaging stud finder that utilizes RF technology
to distinguish between materials behind the wall."

It doesn't say the word "RADAR".

Whereas here, it does say RADAR.

https://www.gearbrain.com/review-walabot-3d-imaging-device-diy-stud-finder-2093324755.html

"Walabot is one of the first companies to use RF radar
to create 3D images on the screen. The device has the
capability to see 4 inches (10cm) deep behind a drywall
or concrete. it can detect normal things which you would
expect behind a wall like studs, wiring and pipes. The
device can help you see leaks, broken pipes, structural
damage to your foundation and even detect little unwanted
guests like rodents."

And I'm sure the rodents smile and give you their good side,
when you scan them.

There is a video on the gearbrain page, which shows the "proxy"
for a stud, when it spots a stud. But when it spots a non-stud,
a grainy blob appears on the screen of the smartphone instead.
It does not particularly speak of high resolution. If a rodent
was present, presumably the only info would be the relative size,
like small irregular blob for mouse, large irregular blob for rat.
You won't be able to see the rat smiling at you, unfortunately.

Read the low star reviews on Amazon, especially the reviews where people
have actually attempted to use it!

It doesn't matter how much AI you incorporate into the device if the
underlying principle of operation is somewhat dodgy or unreliable when
operated in real world conditions.

Basic unit
Crap in = crap out.

AI unit
Crap in = highly processed crap out.

As usual, Big Clive has a teardown (from 7 years ago):
https://www.youtube.com/watch?v=6fJEm7X_ZuQ

It does seem to be able to do 2D detection.

If it's sending out pulses and looking for returns then I suppose that does
count as phased array radar.

Clive's one has 18 detectors in a grid pattern. Maybe they can get
additional resolution from phasing them, I don't know. It looks like some
of the other versions have slightly more antennas.

A dev kit is available with more details of the sensors in action:

Yep, was me, back to magnets :-)

Although there is one due at Lidl tomorrow so I might give it a go:

Even if it worked . . .

And what its CSA is, and whether it has VIR insulation (plus the
condition of it :-) )

From a brief play, it seems pretty good - reliable on electrical cables, and
finds studs fairly well. Metal a bit more hit/miss.
