P.S. I notice you're in New Mexico and discovered this on a hike.
There are a lot of US government installations in the desert in Nevada
and New Mexico that no doubt have interesting sensors and such like
around them. The (high speed interstate-quality but unmarked) road
leading to Groom Lake, for example, has some "cactus" plants in the
open areas that are unlike those in surrounding areas. Perhaps it is a
people (urine, movement etc.) sensor for detecting bad guys.

Best regards,

back in the 70s or 80s they used to put rejected semiconductor parts
in with cement and pave cement roads in california. they probably did
the same in new mexico.

I used to design electronic electric (KWH) meters, so I bought a
couple of Consumertronics' publications on how to cheat meters, just
so I'd know the tricks. The stuff was expensive, poorly written and
copied, and absolute, idiotic crap.

Looks like the bottom of a TO-5 transistor socket to me. The pin dimensions
are exactly right. I have some black glass filled nylon ones 9.5mm
diameter, would not be at all surprised to find 8mm diameter white ceramic
ones were made.

"Rounding at the ends of the pins/rods indicate some long-term wear"

More like someone tinned them with a soldering iron.

Lost ancient civilisations also used to build their electronics on a 0.1"
pitch - how quaint.

How come it got sprayed with paint half way through the photo session?

Actually, Spehro, it's not me that's in New Mexico, it's John Williams
(MSEE). I stumbled across his site by accident, after running into another
web page by the same guy, which explains the construction of the great
pyramids (hydraulically driven winches, pumps, elevators, and so on).

http://www.tsc-global.com/cheops.html

He's published all this in a convenient 25,100 word publication, with the
following disclaimer: "As Consumertronics policy uniformly applied to all
of its publications, Consumertronics assumes no responsibility for anything
it publishes."

His home page is a wonder to behold. Be forewarned that everything there is
"eye-popping." Failure to wear protective eyewear is your problem.

I think it's Fred Flintone's charger for his mobile phone.

"pin/rod spacing is 2.5 mm" that's the familiar standard
0.1"-spacing connector insert, e.g. within three-pin DIN
plugs, etc.

Thanks,

Oh, I didn't notice that. I suppose that's too small and fragile
for Fred Flintstone. It may have belonged to one of the 7 dwarfs
then. The pins are very short also, 3mm. The 4th pictures shows
a hole, probably the exit for the cable. The open-circuit on
all pins, tells me that it is broke. That explains why the
dwarfs have thrown it away ;)

It looks as though it is made of pumice - very soft and easy to cut.

Yes, also, making something deliberately that *looks* like a rock is
pretty easy using polymer materials. They are typically relatively low
density compared to real ones; you'd never be fooled if you hefted
one.

LOL- so you actually can be funny on occasion. That gizmo is very likely
a relic from geophysical exploration/prospecting used to detect pressure
wave from test explosion. The rock is about the size of a chip from a
larger initial installation, or may have been just a practice piece.
That type of hole can be cut with water jets and the sensor cemented in
place. But as for this Williams nutcase, he should remove the plug to
discover micro-etched directions to a location containing time-capsule
archives of the previous advanced civilization, all of their ancient
secrets, and how they met their demise. That's so exciting-yawn...

That *does* look just like a Switchcraft mic connector. They are,
incidentally, great, cheap, rugged connectors, excellent for
instrumentation or connecting rocks.
