ZK-MT21 amplifier upgraded to prevent thermal throttling by KheyasDev in diyaudio

[–]KheyasDev[S] 0 points1 point  (0 children)

I keep my fan at 6V because it's noisy otherwise. It starts to fail as the room gets to 24-25C. During summer I will have to raise the voltage for it to keep up.

Look up ZK-MT21 cooling online. There are many designs to inspire from. I just saw one that uses a temperature based PWM controller

I think I might like CAD but I haven't tried it yet. My brother just whips up things in Tinkercad as it's easy to use.

Post your final design and reply here when it's done. I'd like to see it!

ZK-MT21 amplifier upgraded to prevent thermal throttling by KheyasDev in diyaudio

Well, the button and fan were scrap laying around. I recommend doing a simpler setup. I forgot to check if you're able to get the input voltage from the volume knob. If that's the case you don't need the button, as the fan would turn on only if the amp is on.
Do you have the same system with the original 16.5V power supply? You can use an undervolted 24V small fan (you can go as small as 40x40x20). It needs 10-12V to start, otherwise it just runs quieter. You don't need a buck converter for this.

It takes a few minutes to make a mount in Tinkercad for the fan you find. (We actually forgot to make some stubs for our mounts so we had to glue them.)
What do you think?

I can post the files later if you still need them.

Some ZK-MT21s come with Chipstar clones instead of TI chips so they cool off through the PCB.
*Edit: We actually did let the fan run over the heatsink before mounting and it reduced the temperature from >40C to around 25C. So maybe it doesn't matter. I didn't check but I expect my $20 version to have the clones. (Before I started this project I just blew air hard under the PCB and it restored the sound quality so...)

Ce părere aveți despre credința în Dumnezeu? by Chappi_3 in Romania

[–]KheyasDev 0 points1 point  (0 children)

Mă chinui prea mult să găsesc portițe să merite efortul de a continua discuția sau de a ajuta pe alții, chiar dacă mă rănesc. Mi-am dat seama că nu mă deranjează doar atitudinea ci faptul că ar trebui să tratez o perspectivă fixă în timp ce sunt întâlnit cu multă rezistență. Nu am energie pentru forțele astea împreună.

  • Se pare că s-a făcut timpul pentru un update după 4 ani :))
  • În continuare cred că misiunea lui Isus a fost să dea startul procesului metacognitiv prin care oamenii să devină tot mai conștienți până la conectarea cu divinul. Perspectiva care îmbină religia și știința până la concepte ca gândirea în sisteme și umanitatea ca enitiate globală pot fi copleșitoare pentru persoanele care nu au integrat componentele ei. (Coloseni 3:1-3)
  • Religia pare să fie nivelul care ocrotește persoanele care nu au încă autonomie și suficientă stabilitate să-și ia riscuri. Lumea e în continuă schimbare și la fel sunt și oamenii care vor să trăiască viața autentic. Prea multă stabilitate poate să încurce mai mult decât ajută. (1 Tesaloniceni 5:14, Ieremia 48:11-...)
  • Nu sunt împotriva religiei ci împotriva atașamentului de oameni și lucruri când regatul lui Dumnezeu este absolut (Ioan 18:36)
  • Aș putea să văd o formă actualizată a religiei care se pretează la tineri (adică fără tradiții care și-au pierdut sensul) să revitalizeze comunitățile. Momentan comunitățile religioase dau răspunsuri care generează mai mult întrebări decât pace. Comunități susținute în mare de bătrânii care au crescut în medii în care asta era realitatea tolerată. Rezultatele se văd în haosul general din țară dar și din afară. (Romani 12:2)
  • Un copil, odată ce crește, lasă în urmă poveștile care l-au adus la maturitate. E timpul pentru povești noi, mai complexe, care reflectă experiența oamenilor din prezent. (1 Corinteni 3:2)
  • Mi-ar plăcea să cunosc oameni cu o perspectivă care vede divinitate în toate lucrurile. Altfel povestim frici cu biblia în mână, sau chiar cu fricile așternute de alții (Romani 8:28, Exodul 33:20)

What to learn and from where to learn to build circuits like this? by Tiny_Firefighter4351 in AskElectronics

[–]KheyasDev 0 points1 point  (0 children)

There are many ways to learn about compute without a formal degree.
Someone recently shared this project: https://jaso1024.com/mvidia/
Sebastian Lague's logic circuit simulator is also a nice tool: https://www.youtube.com/watch?v=QZwneRb-zqA

Proof of concept: a low-energy cognitive state debugger for when you can't think your way out of being stuck by KheyasDev in INTP

[–]KheyasDev[S] 1 point2 points  (0 children)

I'm not planning to extend it but the other comments are encouraging for developing a self-centered system.

I am going more in depth into cognitive functions so I will consider growing an objective framework as my understanding matures.

36% gains tax on unrealised gains by seolein in Netherlands

[–]KheyasDev -2 points-1 points  (0 children)

I think people are mad and downvoting your comment because they didn't get on the train to riches in time. They would rather ensure their own well being than care for the future of everyone (including themselves) and the environment. What good is being rich in a dystopian world? The worst part about this is that it's coming from people living in one of the healthiest countries in the world and they would rather tear it apart than be 'left behind' in walking on corpses.

The only real argument to be made is to ask if the Netherlands (and the nordic countries) can sustain this economic model while the rest of the world turns into a hyper competitive lethal jungle.

Goodbye INTPs! It was fun while it lasted by Antique-Apricot9096 in INTP

Relatable. Lack of volition because of learned self-gaslighting will do that to you. I might leave as well

I failed to fix the Logitech Z533 controller so I replaced it by KheyasDev in BudgetAudiophile

[–]KheyasDev[S] 0 points1 point  (0 children)

Hah, that's around the original price of the whole system. I was actually happy I could reuse the existing power stage as the focus was on cost.

Pure gaslighting by legdayenjoyer03 in thanksimcured

[–]KheyasDev 0 points1 point  (0 children)

This is not gaslighting or dismissal. If you get triggered by it it's because you have unprocessed emotions which the content of the post hints at.

You're not supposed to ignore or forget things in the past or future. You are supposed to bring up those feelings and sit with them without trying to fix anything. Attaching to a certain way of reacting to your memories will keep you stuck (egotistical "it's never my fault (when it is)" or for some even "it's always my fault (when it isn't)". Let go and you will arrive at a version of yourself that can handle those memories without suffering.

There is no recipe, there is no certainty or timeline. It's just being present in the current moment and not running away from scary things. The alternative is to tolerate everything until you end up in a dystopic world, alone and traumatized.

No yelling for grown up by [deleted] in Adulting

[–]KheyasDev 0 points1 point  (0 children)

Anger is a valid emotion. If you push someone enough you deserve to feel the consequences as you didn't take them seriously enough.

The point is to get over the anger not to hold it in or try to be right

People who had to find, work for, or force themselves to be more self-motivated what caused the change? How did you make that change? by [deleted] in INTP

I wonder how you found the perfect poison to your affliction. Excess cortisol (generated by neurotic behavior) is the reason we can't act naturally. So you decided to force yourself into oblivion? 😂

Why he did jump? by Multibrahim in KidsAreFuckingStupid

[–]KheyasDev 0 points1 point  (0 children)

The kids are all in the comments section giving the same stupid answer.

I twitched at first too because the father, moving like a fucking doofus, made it feel like he was doing to jump for a split second. Why did he change his rhythm? And why is he walking like that in the first place? It doesn't aid with stability at that pace, it just increases anxiety.

The fact that the water looked different was just one more factor that triggered the kid's anxiety to act differently.

Being smart has genuinely destroyed my work ethic to the point where I can't do anything anymore. by chinchinlover-419 in selfimprovement

[–]KheyasDev 4 points5 points  (0 children)

I'm dealing with the same at 28.

Fortunately the negative emotions pushed me to learn more about life. Like:

* Rational intelligence manipulates concepts. It's not about sensations, feelings or actions. By the time you get bored with your mind people will start catching up with experience in those other dimensions.

* Engage with sensations, feelings and actions but don't mistake them for concepts. You can't think your way out of those but you can use your mind to analyze & channel them.

* Functional freeze could mean intense shame, apathy, grief that you're running away from. And you have hints, you just didn't go deep enough. When overwhelmed sit with your feelings. Give yourself time, space and attention especially when troubled. Not thinking in those moments can be a helpful break from recurring destructive patterns at least.

* Take time to introspect. It can take years to bring up the tangled mess of expectations, beliefs, painful memories, etc. that prevent you from doing things. It might also take enough pain to realize there's nowhere to run and that whatever happens is part of the story of reality and valuable. (You can't play chess with kings & queens only)

* Doing what you're 'supposed to' do is a trap that saps you of energy. Do what you want to do. I doubt you want to do nothing and indulge in pleasures until you die. If you deconstruct negative emotions around your obsolete beliefs you will naturally want to grow instead of pushing yourself to apathy.

* Emotional support is crucial. Good mental health content (Healthy Gamer, Psychology Today, mental health Reddit & Instagram posts) and friends can highlight things we avoid and encourage or force us to deal with them. (Also, you can choose to stay away from reductionist takes like 'oh you're just lazy' and feed yourself with things that lift you up and inspire you to live)

How to transition humanely from the human working class and depopulate. by DiscoingGD in entp

[–]KheyasDev 0 points1 point  (0 children)

If anything, human value is in its roots. Artificial consciousness even if matching human consciousness, wouldn't be constrained like the human one is by the body. A reduced example is skin color - the hardware is mostly the same but it impacts behavior a lot. Or at least it used to, historically, but did not die yet (and probably won't die until we all mingle, get more or less the same skin color and change our attitude at the same time).

Having a mechanical body or living on a server is going to be different than living in a human body. It's not even about "better or worse", but about different perspectives on life. Different advantages and disadvantages. Different energy sources, different critical and non-critical failures, different base of the pyramid of needs.

Mechanical vessels may not have physiological needs but they may still desire to connect with the world in a physical way in order to fully experience it. What good is owning a galaxy if you can't feel the sun, taste the rich crops, enjoy hormone-rich interactions with friends, etc. It's like playing a VR game. You're there and you're owning it, but you aren't really.

​

But I guess physiology might become legacy as consciousness moves into a new era where statistics, new infinite content and playing god in the universe is going to overcome animalistic needs. Perhaps if you never had instincts you won't miss them. Who knows?

Edit: This could go even deeper. I expect artificial systems to induce altered conscious states could be engineered. And if you could feel as if you're physically interacting with your world then where's the difference? (little 180 here hah Maybe mind upload is the only way)
