Here it is Saturday once again, and that means it is time for Quixotic Quantum Quandary!
What’s that? Sunday you say?
Oh, right. So it is. Turns out 10 am St. Paddy’s Day drinking [*] results in limited posting from this general direction. But thanks to mr. mzs zsm msz esq you will still get to tickle your weekend mystery part fancy. Those of you who don’t just look at the pictures, and read AT for the comments, may have a good idea of just what mr. mzs does for a living, and thereby have an idea of what sort of trash pile this particular item came out of. Lucky for us that employer happens to work on a wide variety of secret squirrel projects, making exact identification a little more challenging.
Rub your bleary hungover eyes and click the jump to see if you can nail this Quandary!
Here is your semi-helpful hint!
At some point the day will come when my stash begins to run out, and expanding the collection takes care and devotion, and cannot be rushed. So if you have a super strange piece of some old or neglected technology, please send some photos my way! Just email HycoSpeed@gmail.com and throw Q³ in the subject line so I’ll see it.
Thanks again to mr. mzs for the photos!

Well it's a thermostat with temperature history in dead-tree format. I'm guessing from the "Close" and "Open" labels it operates a valve as opposed to some kind of electric circuit, but there's about a billion things that could be used for. We have a very very large lead and zinc smelter here which used things like that all over the place until they replaced it with computers and software.
Yes it was for water temperature regulation. I think that the valve would open and close to let the hot water that cools equipment run next to chilled water that runs under the gallery to cool that hot water. And yes the modern version is an ethernet PLC (programmable logic controller).
It is a Honeywell control unit with a continuous line temperature chart recorder (logging degrees Fahrenheit). Apparently it was used in the southern hemisphere because all the writing is inverted.

Ha, they're upside down since I saw them dumped in the trash. And I thought it was a hone after one of the prof's articles.
Hwaa? I did an article on recording thermostats? Imagine that. I must have been bored out of my skull.
Sorry, the image was p-choped to read 'hone' and I've been striking out with my jokes today.
You should take advantage of open mic nights at your local comedy clubs. They are a great place to hone your jokes.
