GenRad and pinfeed part 2/4
Continued from Part 1 re-introducing GenRad. = = = = = GenRad’s chart recorder followed a common pattern, with the usual GR extras to satisfy peculiar needs. The common pattern was a pinfeed drive for the paper and a solenoid controlled by negative feedback pushing the pen back and forth. The pen was driven by…

GenRad and pinfeed part 3/4
Continued from part 2, the more modern chart recorder. = = = = = Moving a pen back and forth requires a fair amount of force. It was always possible with mechanical signals like an aneroid barometer, or strong electrical signals like a telegraph. Morse’s 1840 telegraph used a moving pen. But a delicate signal…

Genrad and pinfeed part 4/4
Continued from part 3. = = = = = In between GenRad’s strange photo-film oscillograph in the ’20s and its own pinfeed chart recorder in the ’50s, GR collaborated with Esterline. The Esterline pinfeed chart recorder was the standard in many industries. It was tough, portable, and simple to use. GenRad made a signal conditioner…

Just figured this out
I’m sure this explanation is available on Google, but I figured it out for myself and I’m proud. Often I’ll see frost on roofs and other surfaces when the outside ambient is about 38. The previous day was up in the 40s or 50s, and there was no actual freezing in recent days. Why do…

Refreshing
John Ray, in charge of cleaning up Sammy’s bankrupt fraud, offers some welcome clarity. Most of the time we hear cautious lawyered-up buzzwords from people in Ray’s position. = = = = = START RAY: Never in my career have I seen such a complete failure of corporate controls and such a complete absence of…

Not unprecedented
Greenwald discusses some fool who made the mistake of working for Trump for a few days. Now the fool is in jail, and Greenwald calls it unjust and unprecedented. Of course it’s unjust. Everything in politics is WAY beyond unjust. Words like justice shouldn’t be ruined and blasphemed by applying them to politics. But it’s…

Schwellenbach reprint
Linked in previous, worth a reprint. = = = = = REPRINT FROM 2015 Now that I’ve grown more familiar with Emerson, this feels like a good time to transcribe Schwellenbach’s 1938 speech fully and exactly (except that I substituted ‘nobody’ for ‘noone’, which I can’t stand.) In my previous partial transcription I wasn’t sure…

Cold and hard
As the drug-based eugenics campaign continues, the non-drugged citizens are turning COLD AND HARD, and I don’t blame them. Ordinary citizens are tired of the CARNAGE. This response is growing fast. After you’ve spent years and years following all the rules, “voting” for the “right” candidates and paying taxes, and all the candidates break all…

Random stupid thought of the day
My view of religion is pretty much the standard ‘watchmaker deist’. There’s plenty of evidence for a designer of living things. Evolution simply can’t explain the structures and functions of life, though some form of evolution does occur, perhaps only in the epigenes. There’s no evidence at all of maintenance or customer service by the…

Fun to watch
Journalists incapable of thinking, part 4368549678578758347854378. A “journalist” monster pleaded for public support so they can continue smashing and torturing the public. The public uniformly and unanimously responded FUCK YOU. = = = = = In fairness, most of the “independents” are no better. The Trump cult and the Biden cult are equivalent. Outside of…

Not a revelation as usual
According to whistleblowers Google’s AI isn’t “neutral” but reflects the biases of the designers. SHOCKEDSHOCKEDSHOCKED!!!!!! Jesus Christ. You don’t need a whistleblower to “reveal” this. Every real programmer or record-keeper or accountant knows that a program reflects the preferences of the designer. This is especially true of models and simulations, no matter how complex. Any…

Not just fire
An article pointed by MSN discussed a new trend in apt buildings. Most US codes require two stairways, for fire access among other things. Supposedly fire prevention is so good now that we can build cheaper with only one stairway. First, that’s nonsense. Second, the other things are important. Here’s my floor plan of Grandma’s…

Superdemon finally fired
Superdemon Lutz, head of the Spokane County Public Genocide Office, was fired for mysterious reasons in the middle of the holocaust. I stopped following the details, but assumed he was fired for being ineffectively evil, because nobody is ever fired for being TOO evil. Turns out he WAS fired for being too evil, which makes…

Perpetual puzzle
This AMC dealer training strip proves that the Hudson fail-safe braking system was still being made in ’57, the last year of the brand. (Books and articles are vague and inconsistent on this fact.) I don’t expect any regard for safety from the big three, but AMC was actively SELLING this feature up to the…

We are famileeeeeee
The Trump scampaign continues sending me those weird lovey-dovey emails. Now they want me to help Trump keep his Trump Tower. Ping! Cults are substitute families. Gangs are substitute families. Trump is a born and trained gangster. The Trump cult/gang is a family. In old movies, the inherited family farm is threatened by Snidely Whiplash…
