Yes

"MSH-P/HC/NC/5/V/P/0 - 3% Volume Ethylene = 0.4V - 2.4V"

We built that into a custom SS body with a Delrin mounting insert, and ran the serial connections to a custom board that interfaced with up to 8x sensor locations (in conjunction with some other sensor elements). The elements were ~US$200/ea ~4.5 years ago.

These are fancy interpolated IR absorption sensors internally, so any gases of similar concentrations could throw off the readings; depends on the environment. Would be BEST to calibrate to local atmosphere conditions of the installation, but that's not really something you can sell. :P

On the other end of the spectrum (not testing specifications, but just simply "does it network?"), I have successfully ran a 100BASE-TX connection between industrial equipment using individual (not twisted) 24-AWG wires over 20ft.

I use path tracing for scientific/engineering studies of light propagation; in particular, I attempt to simulate monochromatic light sources and reflective/transmissive/absorptive material configurations (ranging from specular to diffusive, and everything in between) to determine the irradiance delivered to specific geometries. In the past I have used commercial packages like ASAP (APEX Solidworks add-in), Zemax, and FRED (in order of preference).

Prions are like gamma-induced bit flips, Viroids are like small code patches, and Viruses are self-deploying code patches.

Displays with relatively simple off-board processing are common, too; you can often run a big display pretty reasonably with a 16MHz Arduino: buydisplay.com

I started reading it, and I thought "this style seems very familiar". When I got to the first schematic, it clicked and I checked the header for the author's name; sure enough, Forrest Mims!

That precedent was already established with Credit companies.

>they can't help themselves once they get a whiff of some new power

Semantics, but I don't think it is necessarily the "power", so much as it is a new vector to get the evidence they feel that they need to perform their job with less effort. It is a lazy method that circumvents the laws that stand in their way for good reasons.

Whatever happened to good-old two-part JB Weld? Is that just a regional product? I thought everyone knew about it.

Yeah, I was on 4chan as a 16yo-20yo regular lurker starting back in 2004; never an active poster, just commenting randomly and joining in conversations on various boards. It was a decent anonymous community, sometimes I'd wander over to /b/ and it would be like walking past an apartment building at night and seeing completely random (sometimes disturbing) things going on through all of the windows; lurking on /b/ was the online equivalent of being an active peeping tom in a neighborhood without curtains.

When moot sold the domain a few years ago to a former 2chan admin, I noticed it barely changed. But I haven't really visited much since 2009 or so...
