"If you’re not then this seems quite paranoid, bordering on LARPing."
There are sooooooo many other situations where such device lockdown is warranted. Government intrusion, sensitive industry, journalism, anything ITAR/EAR covered, and more. Your reduction to a single issue is absurd.
A good chunk of us are in tune (pun intended) with our instruments to the point that we can simply feel the vibrations and know where we are with regards to tuning.
That sounds like a very useful skill for a working player. But it seems to come with a couple of significant conditions.
I can believe this is possible. But I don't think this is a reasonable thing as a baseline expectation for a player with 6 weeks of experience, which was the original comment in this thread.
I don't know the details, but I imagine you're feeling beats transmitted through the neck or something. But if that is the case (an assumption) it still requires you to have at least one known-good string, unless you're playing solo.
So, for these circumstances, and others, a pedal-based or clip-on headstock tuner seem like they still have plenty of practical application.
depends on the instrument. with acoustic instruments the resonance chamber is often tuned so that you can feel the body itself vibrating more when you're in tune
I don't doubt that this is true at some level. But is it really perceptible for 20cent differences? I don't know anything about this, but I'd be surprised. I'd say +/- 20 cents is a bare minimum for calling something "tuned", but low single digits is really the goal.
no, i still use an electronic tuner with my acoustic guitar. but i can feel the body vibrating differently when i get close to being in tune vs being a semitone off
This is basic physics controlling the effect here, not electrical routing. Speakers are microphones by their very design. To make them work as a microphone, you merely speak into them with them plugged into an input jack that provides at minimum a line level electrical signal to be modified by wiggling the speaker cone/diaphragm back and forth.
Yes, but the computer doesn't have the firmware to "record" that signal from the speaker output pins. Thus, to record from the speakers acting like microphones, would require rewiring the headphone cable, for the vast majority of computing devices.
If you click "record" on your computer, there's no way to tell it to record signal from the speaker output channels, even if you write a custom low-level application directly making OS calls. The OS can't even do it, because it's not supported by the firmware.
"Yes, but the computer doesn't have the firmware to "record" that signal from the speaker output pins."
No, you plug directly into the microphone jack, that is what is providing your line level reference signal that gets changed by motion in the diaphragm. Zero rewiring required.
"The Switch is a toy, it's not a PC. Apart from a few shitty PC ports, it runs its games just fine, so in what sense is it really "underpowered"?"
Well this comment down below brings it about really quickly:
"Switch 2 has better FPS for Switch 1 games. Like BotW stops having terrible FPS drops in certain scenarios."
If you need a newer-gen piece of hardware to run an older-gen FIRST PARTY title at acceptable speeds without issues then I'm going to say you are ABSOLUTELY and PURPOSEFULLY selling underpowered hardware (and Nintendo has been doing it since the days of the NES. So many first-party titles with slowdowns because the hardware was not up to the task.)
Switch also tried to live in the portable console niche, above handhelds, and this was several years before Steam Deck. SOC development favors the later devices, obviously.
"There's a reason microcontrollers are used for tasks like debouncing switches."
Because people are too cheap (or fail that hard at basic analog electronic control) to get a proper single-pole single-throw switch with a pair of MOSFETs in a monostable mode, or use an S-R flip-flop latch to debounce, or even a very simple R-C filter circuit.
"Throw a microcontroller on it and call it a day" is the surest sign of someone not properly educated in electronic engineering.
If you live under a waterfall you'll use 1000 gallons of fresh water pumped at blasting high speed to wash a cup.
We live under a waterfall of cpus and gates in general, and organisms don't care if their environment is perverse. A thoughtless organism will happily consume 1000 units of a free resource just to get 1 unit of some other non-free resource.
And a lot of humans are the worst. Thinking beings who elect not to care about anything like that. Like spammers that operate simply because sending email is free for the sender. They get almost nothing from it, and it costs everyone else a lot, but it costs them even less than the tiny bit they gain, and the external costs don't matter to them the tiniest bit.
But the environment is perverse, created by economies of scale and Asian slave labor and the push for advancement for it's own sake which makes existing useful things artificially low value by being "obsolete".
A software version of that might be making apps with Electron. It doesn't matter how much cpu and ram and disk and general mass of tech stack it takes to make some trivial app. The developers precious time outweighs all other considerations. If they can make the app in a few minutes with no effort instead of a few hours, it doesn't matter how much of everyone else's resources they consume since their time is valuable and 1M other people's cpus are free.
Because nothing is faster and more responsive than direct hardware logic.
"a simple microcontroller is usually cheaper than a 555 nowadays, often doesn't require external components,"
Often? Every UC I've ever used has required a whole slew of caps and resistors just to get the thing to take in operative firmware through a programming port. Even the simple light flashers for vehicles that I've made using a UC and accelerometer need at least two caps and two resistors to make a proper circuit that allows for flashing info to the controller.
"so even if all you wanted was a single function like an edge-triggered pulse, or generate a single frequency, it probably still makes sense to use a microcontroller from a board design perspective."
Frequency generation? Inductor, capacitor, input voltage. Zero UC required and guaranteed to be cheaper.
"As soon as you want anything slightly more complicated, odds are you can replace a ton of other circuitry on the board with that single chip and a small program."
And accomplish things at a glacial speed that a basic hardware-only solution would've solved. As an example - BOSS pedals have basically zero latency because it is all analog. All these newer Line 6 and POD and other digital FX pedal makers have horrible latency, some I've measured past 50ms (almost as bad as trying to live-monitor a Windows Audio device.) It has been this way for the over 30 years I've been playing guitar.
Most times, raw hardware with zero software is THE way to go. Anything else is just a performance loss.

ATtiny for example. Many others only requiring an external capacitor, and complaining about a decoupling cap on a chip replacing a 555 that also needs an RC network to function seems rather petty.
> And accomplish things at a glacial speed that a basic hardware-only solution would've solved.
Most of these uCs operate at least 1 MHz or higher. The ATtiny85 can run at 8MHz from the internal oscillator and has an interrupt latency of 4-6 cycles. To achieve anything that's replacing something you'd do with a 555, you'd have to try incredibly hard to get latency as bad as you're describing. Perhaps they're actually doing something significantly more complicated than just replacing a 555?
My Kyocera will work in orbit and withstand intense radiation. In fact, this very moment my new Duraforce Pro 3 is having fun in a launch-testing thermal/vac chamber.
Kyocera's 'flagship' is high-reliability phones in absolute garbage environments.
Samsung's 'flagship' overheats and earns them class-action lawsuits.
Motorola's 'flagship' is a hinged throwback to the 90s.
Apple's 'flagship' is an overpriced piece of vendor lock-in.
Meanwhile my phone takes serious abuse and laughs at it. I've dropped it and watched it go more than 700 feet down the side of a mountain (Chambless Skarn) and BARELY chip the screen protector. Waterproofing still intact. Case barely scratched.
What you consider a flagship phone is a brittle piece of junk in my hands.
That's not a radiation hardened chip, it's regular off-the-shelf consumer electronics. The "solar radiation" test they advertise is part of MIL-STD-810H. It tests whether the electronics survive regular sunlight on earth. The only ionizing radiation this phone is rated for is UV light.
At least if it had registered memory there might be an argument that it has some radiation resistance, but no it's plain old LPDDR4x.
Ulefone Armor 29 Ultra has the same MIL-STD-810H conformance with "radiation hardening", 16GB of RAM and a flagship Dimensity 9300+. Just not a removable battery.
Funny because the Qualcomm sm7450-ab snapdragon 7 gen-1 page lists itself as only supporting LPDDR5.
>also do you mean perhaps Strontium-90?
Nope. Strontium-60. 25 year half life compared to Sr-90's ~29. It's what we like to use in real space-environment testing on the ground. Nasty stuff.
>source?
You can actually probe your hardware and see what sort of ECC is enabled on a Droid phone. In this case, in-line ECC, so that means some of the RAM is actually sacrificed for error correction instead of having a dedicated extra chip (256 bit, 240 of that is data 16 bit is error correction.) What's awesome about that is that enabling ECC is simply a bit flip in firmware and you don't need the extra RAM modules installed - the installed memory can already do it. You don't need the extra hardware.
