Some model trains operate on a system called DCC, or Digital Command Control. As an alternative to DC, or Direct Current-driven models, it’s a commonly-held misconception that DCC runs on an AC, or Alternating Current circuit. In reality, it’s still using direct current, but combining it with PWM, or Pulse Width Modulation, to embed digital signals at slightly higher voltages than the regular operating voltage. These signals can be used to address individual models and send commands that allow for a model to have more functions than a DC model would be capable of, such as more sophisticated lighting, finer motor controls, sound features, consists, speed matching, automation, and a lot more.

“I would now like to present my theories on Dark Souls lore, and why Vaatividya is wrong about nearly everything.”

Hell yea. I love hearing about other peoples passions.

Ok for a moment I thought she meant people from Appalachia

It’s funny because the people who are like ‘no one wants to hear it’ will launch into a diatribe about garden hoses or something like they don’t realize that is a niche interest. I had to catch a relative out about that. I think she’s gotten a bit kinder since.

What if they’re flat earthers?

It depends. I wouldn’t listen to Andrew Tate, no matter how passionate he may be. I’d rather try to understand flat earthers than him.

So, you know how most Australian mammals are marsupials (the ones with a pouch)? Well, the fossil record suggests marsupials first arose in the Americas and later went on to reach Australia around 50 million years ago, probably just one lucky small species that later would become kangaroos, koalas, tasmanian devils and a bunch of other fun dudes. The thing is, as far as we’re aware, the timeline of events means they got to Australia after it got separated from the rest of Gondwana with two interesting implications:

First, that they got there through rafting, which means a couple individuals crossed some expanse of ocean on top of some floating vegetation or whatever and ended up being lucky enough to survive till they landed on a new continent. Interestingly, that’s also the main theory on how (non-human) primates got from Africa to South America.

Secondly, that they migrated from South America to a not-yet-frozen-Antarctica and only then to Australia, which means all their friends who lived on Antarctica and were lucky enough to not end up in the middle of the ocean on top of some floating tree trunk ended up unknowingly condemning their descendants as the continent slowly drifted southwards and completely froze up around 10 million years ago.

It’s very depressing to ask someone about their weekend and the answer is always nothing more than TV and sleep.

I know somebody who maintains a gas powered go kart that his son races with. I don’t know much about it, and I’d never be into it, but at least hearing about what he is up to is interesting.

I’m fascinated by this woodworking tool called the Festool Domino. It’s got the form factor of a biscuit joiner, but it’s a router instead of a circular saw, so it cuts a deep, short, wide mortise to receive a loose tenon they call a Domino.

This tool is still protected under patent by its inventor, it’s brand new. But the type of joinery it’s for - loose tenons - are older than writing. Prehistoric wooden structures have been found held together with loose tenons. Some 8,000 years we’ve been making mortise and tenon joints, and the technology is STILL under development.

This post made me think to recommend the series ‘Connections’ by James Burke if you vibe on the strange relationship between odd events and inventions in history that lead us…here.

Caveat: it was filmed in the 70s so enjoy polyester and bell bottoms, but also scary prescient predictions, some of which have already come to pass.

Here’s a summary of a few passion project research holes I went down over the past few years (citations available):

• It’s very likely that the Gospel of Thomas was related to the writings of Lucretius, there’s a high chance the historical Jesus was talking about indivisible parts of matter (atomism) and a decent chance he was talking about natural selection, both ideas extensively found in Lucretius in some cases with near identical language to what’s both canonical and apocryphal
• Nefertiti (“beautiful woman who arrived”) and the story of Helen of Troy have some remarkable overlaps, particularly given Herodotus’s account of Helen ending up in Egypt the whole time - and the two datable parts of Herodotus’s version both line up with the 18th dynasty, which was parallel to the Mycenaean conquest of Anatolia
• Ramses II was described as appearing to be a Lybian Berber in his forensic examination, and had around 50 sons, which makes the ancient claims the story of Danaus (the Lybian ruler who was brother to a Pharoh with 50 sons) occurred in the 19th dynasty a bit more intriguing
• There may have been some truth to a Moses/Mopsus narrative at the tail end of the 19th dynasty, but it would have related to the twelve groups of tribes of Anatolian peoples captured by Ramses II at Kadesh and some of their later actions as part of the confederation referred to as “the sea peoples” - this lines up more closely with Greek and Egyptian accounts of the Exodus tale as multiethnic or including Greek ancestors too. Some of those sea peoples were later forcibly relocated to the Southern Levant where there was cohabitation near the local Israelites who later on have stories about these events, talk about Dan “staying on their ships” or trading with Tyre alongside the Greeks, and recent archeology has found Aegean style pottery made with local clay in Tel Dan or the only apiary in the “land of milk and honey” importing Anatolian bees in Tel Rehov, which starts to cast a very different picture of some old stories

No one cares

Most of the time I hear, “Oh, yeah? That’s cool.” End of conversation. I still like my interests and tons of other random people on the internet do too, but my interests don’t generally align with my IRL co-workers unless we’re talking about our kids.

Wait is the Saturn’s ring thing true? That would be awesome if it was true.
