@ElectronicsQuestions

Ask me questions about electronics on the circuit level. I don't know about Raspberry Pi:s, programming modern microcontrollers etc, but I do know about resistors, capacitors, inductors, voltage regulators, op-amps, digital logic, and so on and so forth. I can probably help you repair something or build something. I also know a thing or two about mechanics. If my service is free or paid is up to you! Nostr and Lightning is new to me, I'm trying to learn, so please excuse any errors on my part regarding it. I live in Sweden.

No relay list published yet.

Oh yeah that ones a camera trick due to frame rate. Same with the wheel.

Don’t know about the hovering coin but if they all create a negative magnetic field I can see it being plausible, can’t say I have my head around that one though. However the batteries and the co...

reply to you and @Send_it_Mike: F**k this War

The hovering coin is definitely bullshit. The positive poles of the batteries aren't even connected, and the spoons are connected together. Even if they weren't and the batteries were in circuit, I doubt the one-turn coil would do anything to the coin with the current in question. Even if it did, the coins behavior is not what I would expect from being placed in a magnetic field from a coil.

The battery with magnets in a coil should work.

The animated stickmen on the spinning disc would only be visible on camera, not in person, and only when speed and framerate are perfectly synchronized - a little bit off, and they would be drifting clockwise or counter-clockwise, a lot off, and it wouldn't be recognizable.

Yes, looking again, the stickmen are indeed drifting a little bit, so it's unlikely to be faked. But in person, you would just see a blur.
Guy Swann · 12w
Yeah the batteries and spoons feel like BS to me. Can’t see how that would possibly work

@knutsvanholm : Hi! (I'll write this in English even though we're both Swedish, just in case the same problem affects anyone else who wants to know.) Since a while ago, BIS #177 to be precise, your new episodes doesn't show up on Podbean. (I still use Podbean since I have to download the podcasts, and that doesn't seem possible from Fountain. If I didn't have to, I would've tried it a long time ago.) They still exist if I open the feed, and I can download them by marking the MP3 address, right click, click 'save link as', so they obviously exist, but something has broken the Podbean website's ability to update its page for your podcast. Probably something related to podcasting 2.0.

Just a small annoyance and not a huge problem for me, as mentioned, but it looks as if your podcast was dead for anyone nontechnical, in a hurry, or not thinking that particular problem is likely, i.e. at least 99.9% of people. I don't know if you or anyone you know and/or work with can do anything about it, or if it's a problem with Podbean in particular, but I thought you'd want to know.

Love your podcast, especially the BIA episodes!

The same boiling water that softens the potato hardens the egg. — Roald Dahl

I'm probably going to attract trolls with heavy cognitive dissonance by this post, who didn't think through its meaning, but whatever:

Nostriches: Potato, become an egg!
Potato: How? I'm a potato.
Nostriches: You need the boiling water!
Potato: I told you, I'm a potato, it doesn't harden me, it softens me!
Nostriches: Well, become an egg then!
(return to second line and repeat, or go off into how being a potato is a moral failing etc.)

(The mandatory: Not all nostriches of course. But probably 3/4 of them.)

Thanks. I thought "wasn't this already approved, and didn't concern self-custody?"

That countries can set lower limits for cash is concerning. Sweden, where I live, is probably going to set it low, since cash use is already rare here, and only about half of stores, restaurants, etc. accept it, and despite efforts by lots of people to convince politicians to protect the right to use it, resulting laws has been weak. They obviously don't want to.

Bingo! That’s my fear, it’s a lot of power for only a handful of people to have. Even if it started off with the best intentions, history shows that it’d be abused over time

Dude, Twitter/X is such a shithole. Full of people hating on each other and picking sides. It’s just a bunch of useless noise. If I weren’t a content creator, I’d have deleted all socials exce...

I've never been on Twittex, but I've noticed something here, that only recently floated up to conscious level: There is rarely the hating on each other and picking sides, but when someone writes something IMO rotten of a certain few varieties, it invariably gets huge amounts of zaps and likes, and very rarely opposition in the comments, even though I know there are lots of people here with the same opinion in the matter as me, i.e. thinking it's rotten. The reverse is also true, but not to the same extent - they get opposition a bit more often.

It simply seems like people here are afraid to take conflicts head-on, and I have noticed that in myself too, and I think that one of my reasons is that I don't want to be muted, as many of the people having IMO rotten opinions in some matters, like most of the people here, have good opinions in matters of wanting freedom, and are in one way or another involved with something good with Bitcoin and/or Nostr.

Another reason is that I recognize the style that I associate as common with a specific type of troll, that sometime pops up on Reddit when I was there, and has done here a couple of times, that can provide endless arguments that are very hard to prove wrong even though they are, combined with concealed attacks on not what, but the way, I think (it's hard to explain), and an incredible ability to turn around and draw attention away from a part of the argument they are about to lose, and twist it into another part, intentionally misunderstanding my point of view, etc. It's just exhausting to try to debate them.

It's weird, and sometimes feels very wrong, but good in some ways. And it probably helps Bitcoin and Nostr which is of course good.

Privacy tech is good and completely necessary, but this shit that is spreading around the world needs pressure against it from more angles. How do we get the obvious fact into the heads of people that this isn't about protection, but grabbing more power through controlling narratives, and eventually locking up political opposition? "We can't" isn't a good enough answer if we want to even be able to use privacy tech in the future. If left with as little pushback as is currently the case, they will not stop until it's literally impossible to use private systems, either through being completely blocked or guaranteed to go to prison.
