Previously, and thermionic valve based.
One of the sites I work on has two old Honeywell thermostats on the wall that are like nothing I’ve seen elsewhere and it kinda intrigues me. These have a small bellows inside and act upon temperature changing the pressure of gas sealed within it. I wonder if they have to thus be calibrated for altitude?
I’d guess circa 1960s-1970s based on the date of other gear at this site.
First, the cooling thermostat – it’s a pretty straightforward mercury switch two-stage type. BIG mercury switches, though – much bigger than Honeywell would have put in their standard home HVAC controls…
The setpoint is adjusted using the hex screw on the side.
Next, the heating thermostat, which really had me scratching my head:
The contact arrangement is curious. This thermostat does not appear to just switch on and off, rather, its output appears to be a variable wirewound resistor! Said resistor is also mounted far from the bellows, so it’s definitely not just an anticipator resistor. This makes me wonder if it was actually more of a remote sensor to something fancier—? Apparently it’s a “proportional control” and I wonder what the original heating system up there was. The original HVAC system has been mostly removed and replaced with a boringly modern one.
waaaait for it. I used simple mathematics and it was too much for at least one commenter.
In the late 1990s, my since departed uncle loved listening to a few different programs on WIOD Miami. He wasn’t big on sports commentary, which there was some amount of, but he really loved the programs by the late Neil Rogers and Rick and Suds.
It saddened me to learn this morning that Suds Coleman has passed after a battle with cancer.
I’ll never forget one broadcast of his in particular… As a kid, I didn’t really get a lot of the humor of the shows my uncle liked on WIOD, so I didn’t listen that often, but then he and Rick Riley were there to keep us company through Andrew.
Hurricane Andrew rolled into the Miami area on August 24, 1992. Almost immediately, the television stations went dark and a lot of the other radio stations vanished from the dial or fell dead air. However, of all the goofy places you would not expect to be unaffected… the two tower AM directional in the middle of the freaking BAY stayed up, and WIOD still had power. Their building stood on stilts (a VERY WISE design choice!) and everything stayed powered off their generator and fully on air.
Meanwhile, Rick and Suds were up there in the studio looking down, and from their vantage point, it looked like the bay was just knocking on the station’s door. It probably was, considering how vulnerable the area is to storm surge. The WSVN studio next door had three feet of salt water in it and they were off air. At this point they had lost all telephone lines and other means of communication with the outside world, but were still on the air…. and they were just providing commentary on the objects and satellite dishes from WSVN flying past their windows.
They didn’t have much to report other than that due to the loss of communications, but hearing them on the air from a darkened house buried in about 30 feet of uprooted trees with flaming pieces of debris from a nearby tree that was hitting the power lines somehow managed to convince me that we’d all go outside the next morning and everyone else would still be there.
It’s things like that which will always show just how valuable the local broadcasters are to the community, and I thank him so much for his contributions.
… Back at’cha.
So earlier, Elon Musk posted someone else’s art to his Twitter then claimed crediting the artist is “destroying the medium” then he ragequit Twitter after being called out on it, by “deleting” his account, but not actually deleting it.
I feel kinda dirty for once looking up to this turd sandwich. I’m sorry, everyone. Here, enjoy some random derp pictures from my collection:
Uh someone forgot to water the city and it wilted.
We had a Telos One X Six blow up on us, sadly.
A second unit that needed a power supply was sent over from our other stations down south. as I replaced the power supply, I admired what insane dedication to electronic design went into this monster. Image heavy post follows.

So that buzzing sound my 2014 Forester’s a/c compressor made since last year? Yeah it wasn’t supposed to do that.
I checked the clutch gap today after suffering mild heat exhaustion in 102 degree weather with the A/C blowing warm… .82 millimeter… Factory specs say 0.1-0.6mm.
Thus it was time to subtract a shim from the shaft.
And then my workday jumped to like 10 hours and crap so what follows:
There’s actually nothing to stop this from turning so I just grabbed it with my hand and used the wrench on the center bolt because I’m some scary beast
The compressor drive plate before cleaning
Pulley side after removing all three shims and before cleaning
I saw it recommended to torque the center to 10 foot pounds which worked fine with my bare hands, once again….
Now it seems I just have cold air constantly and no buzzing noise (was that it slipping??)
Lately, Cassie has liked to hide in this box and play with the ribbon as we swing it in front.
What a little cutie patootey!
I was gonna say something here about old Telos phone hybrids but……. Meow! Thanks for taking my mind off those, Cassie.
Uh oh, that wasn’t rain I drove in last night.
Also, there’s a long line of cars at the car wash here in town, gee I wonder why?
