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
