Hi,

Pulled this out of the recycle bin as it "looked
interesting" :>

Fully populated PCB but no case to put it in context.
No useful markings on the silkscreen.

10 LEDs arranged in a semicircle -- green followed
by red (e.g., like a meter with a - and + zone).

One power indicator.

One push button (power on/off)

9V battery powered.

Turning it on appears to do a lamp test (though this
could just be a noise spike that temporarily drives
the "meter" up to MAX).

Center of board has a foil pattern similar to what you
would find *in* an RFID tag (1.5" concentric squares).
I.e., suggests it is an antenna.

Now, what might this be *used* for?

Thx,
--don

Sounds like the thing in my hand.

i bought it surplus several years ago. Probably Electronic Goldmine.
A magnetic field detector.

Ghostbuster.

That thing used to go haywire near CRT's. Probably one of the main uses
at the time to check for fields. Yes it works fine on my Fluke
analog/digital scope.

i wonder if we all fell a little better away from the computer CRT's ??
Is there any history event trend ?

Ah, that's possible! I found a bunch of RC kit in
the same pile so wondered if maybe used to measure
signal strength (though I would assume you would
empirically determine this -- e.g., when plane
*crashes*, etc. :> )

I'll see what it does near the microwave...

Be sure to defeat the interlocks to give it plenty of signal.

Assuming s/fell/feel/ ? Recently I three broken LCD monitors, fixed
two of them so no CRTs here now, feel much better!

Hi Robert,

Robert said:
No, i have a RS one, small horn with diode and meter, period.

Well, *this* one lights up like a christmas tree when held
in front of the microwave! :< I wonder if any of my body
parts are glowing??? :-/

Curiously, doesn't seem to react to the WiFi (which I
thought a good possibility) -- which I thought was roughly
the same band (?).
