@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.

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 · 40w
Yeah the batteries and spoons feel like BS to me. Can’t see how that would possibly work

@Knut Svanholm ∞/21M : 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!

We'll look into it!

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

Do they taste good? Or really strongly flavored? Biochemically it is a sympathomimetic, meaning it acts like adrenaline in the body. That’s better than nutmeg, another sort of synpathomimetic tha...

They taste pretty strong, but also sweet. And of course, like cinnamon. Where I live, rice porridge, (similar or identical, not sure, to rice pudding) is a traditional Christmas dish, with cinnamon sticks in it. I've always liked to chew on those when I've eaten the porridge, but they are probably a bit milder since some of the flavor has gone into the porridge while cooking it.

That makes sense. And sounds yummy! I have limited experience with an actual stick of cinnamon, but I used to love pondered cinnamon sugar toast with butter as a kid.

I'm sorry I clicked wrongly

That is just the surface. The SEs they have used are in general insecure, lack any security certifications, and the Coldcards are vulnerable to many supply chain attacks that I have not published yet. Modern attacks with the same method you mentioned btw would cost at most $2K with a DIY setup.

That’s a whole other thing. It’s bee researched and documented. It has to do with their secure element. You can find it and make a decision if it affects your personal threat model.
semisol · 47w
Kind of. The developers of Coldcard do not do not have the security experience required to properly maintain a secure codebase.
