  • Lower frequencies (like the HF range) can propagate further due to reflection/refraction with the earth and the ionosphere. Increasing the frequency can lead to e-skip and troposhpeheric ducting. But even the HF range has shorter wavelengths than our brains, which operate in much lower frequencies (Hz vs MHz). So you would think that our brainwaves would pass through tin-foil much more easily

    But it’s the tin-foil’s electro-conduction that “foils” the electromagnetic waves’ (i.e radio waves’) ability to pass through it. But you would have to have no gaps in the tin-foil to completely block all waves from passing through. So like, an entire foil suit or a walking Faraday cage.

    TL;DR - it’s not about the length of the electromagnetic wave, it’s the electro-conduction (insulating) property of the tin-foil that matters



  • No one cares about you 🙄 for the love of life. Get off it already… you even forced an emoji outta me, just to really get my point across /s

    Sorry sorry, trying to be sarcastic-mean, not actually mean. Just wanted to rib poke for a second, but not at the expense of a person I don’t know. I truly like seeing your activity around here; couldn’t help myself though. Ya dick

    I’m not great at sarcasm lol. I only wish the best for you, ya random squid 🐙





  • Thank you! I was reading the wiki about the “landing” and could “understand” how a current phone would be vastly more than sufficient. I got lost trying to find how an “ESP32” was designed… and then how processor’s were (normally) designed nowadays… and how it all worked together. I guess I was asking if a single “chip” could include all of those things (CPU, RAM, ROM), or if it was multiple “chips”. An integrated circuit is what I think I was trying to dissect. I’m still curious about the inter-workings, but you cleared a whole lot up for me.

    I really appreciate the breakdown, because I didn’t have the terminology to properly search. I guess it still kinda blows my mind how far it’s all progressed

    Edit: And now I’m learning the difference between “Integrated circuit” and “circuit board”… seems silly in hindsight, but the terminology had me a bit confused. Super cool, nonetheless.


  • So I’m not an IT professional by any means, it’s a hobby. But I’m curious if an ESP32 could land a man on the moon. I searched around a bit and am under the assumption that an ESP32 has a CPU or microprocessor of some sort.

    What I’m trying to figure out is: Would a processor on an ESP32 have RAM and ROM built into the chip. I hope I’m asking the right questions.

    It seems like a processor should have RAM for a cache. But I gave up trying to figure out if it would also have built-in ROM (specifically, an ESP32’s processor)

    Do all CPU’s/microprocessors now have SRAM for a cache? Do all also contain ROM? Or is it separate? I guess an ESP32 does require ROM for it’s firmware, regardless? And (maybe?) SRAM in it’s processor?

    I’m beinginng to think an ESP32 would have the “specs” to land a man on the moon?

    Idk, “how true is your statement” is what I’m trying to figure out (but I lack a lot of the technical knowledge), and now I’m curious. If someone could ELI9, I’d appreciate it

    Edit: I did flash the eeprom on some XBOX TSOP chips in the past. So maybe ROM isn’t part of the CPU, but very near-and-dear. Annnnd I’m in a rabbit hold about the anatomy of CPU’s because of a one sentence comment. Please help

    I wouldn’t say no

    Ya may have read too quickly and missed the double negative. It seems that they would like relations with that bird… if that bird were were a person, and talking dirty botany to them

    Edit: and all of botany is dirt-y, when you get to the root of it… I’ll see myself out now
