[@WowYesWow]

Yes

[@nask0]

Indeed

[@ivanalaskevich4736]

In fact, a click creates a blow of a plastic cap on the upper face of a mechanical button. The sharper and stronger pressing, the louder this sound. If you press the button slowly, or do not push the keycap to the lowest position, the sound of this keyboard is much quieter. For "blue" mechanical buttons, an additional sound is created by the impact of… that white element on the bottom of the button. It is also enhanced by keycap. The sound of the membrane keyboard is muffled by rubber dome. There is no such thing in mechanical buttons, so the sound is stronger. If you put a rubber ring between the keycap and + thing on the button, the sound from pressing will also be quieter.

[@naturegirl1999]

[@94D33M]

Could you suggest any silent keyboard that does not make any sound at all ?

[@ivanalaskevich4736]

@@94D33M Rather not, I'm not well versed in the keyboard market, I just know approximately how they work. And I'm not even sure that a 100% silent keyboard is exists, there will always be at least some noise from moving parts. All I can advise is to go to a real store and listen with your own ears, instead of believing ads like “Wow! This keyboard is really silent!”. . . . Although there are 2 more or less silent options ... but you obviously won't like them. "Laser keyboard" and a tablet with a virtual keyboard. There are no moving parts - nothing to make noise, but they are far from comfortable.

[@Steamrick]

Mind you, the input shown was the super-budget option that minimizes complexity. The tradeoff is that when you press more keys at once, there are combinations where the controller is unable to tell which and how many are pressed in total. More expensive keyboards will have different control layouts that allow for more keys to be pressed simultaneously.

[@Fielith]

Cs is cooked

[@breadles5]

this is a really good explanation of how keyboards work. however, one thing to note is that mechanical keyboard clicks on clicky switches generally come from a click mechanism, not the contact between the metal leaves. this can best be demonstrated by using a key switch without a click mechanism, such as a linear switch. which will generally be much quieter than clicky switches. other than that, most of your information is correct. keep up the great work!

I think it might be useful to add that in 5:45 the voltage input on „row 6” goes down because „turning a column off” means connecting it directly to the ground thus making the current flow that way (cause there is only cable resistance there) rather then through higher resistent microcontroler - which explains 0V on row 6 input.

Sorry to inform you, but the click mechanism explained is incorrect. The click in not produced by snapping of metal contact points of the leaf, but when the click jacket(white part below blue stem) strikes the bottom of the stem or the switch.

[@Matoakas]

This channel, that I only found out abt days ago, is amazing. Not only do you answer questions I've had, but also many I - by seeing your thumbnails - wasn't aware of I wanted answered. You do it in such a tremendous way as well! How easy you explain it, is paradoxically not easy. It takes skill to do that in the educational way as you do. Simple and straight to the point. Other than the sponsor section, no time is wasted on anything irrelevant to the content. To me, honestly, that is such a relief - to listen to something that is professional and entertaining, without any annoyance or irrelevancy. Real chill too, with the calm way it's explained. What's so impressive, I think, is you do it the same way in every video - no matter the topic. Many of which are complex. Still, whether it's graphic cards or lithium batteries, inside 30-ish minutes, you make it so anyone can understand it. So, respect! Great video! Great channel!

I want to correct you at 8:15, the “slider” isn’t there on most switches and is mostly just a clicky [blue] switch thing and the slider and stem are one of the same on most switches. On clicky switches it’s commonly called a click jacket because it’s what makes that click sound. When the click jacket passes the tactical bump I’m pretty sure the contacts act like a leaf spring and slam the click jacket to the bottom of the switch thus making a click noise. The contacts also don’t make much noise on activation point if at all.

[@Zippsterman]

Was looking to see someone said this. The clicky bit is a very intentional addition

Ah yes, mechanical keyboards, a very talked point on rhythm game communities since its said that mechanical keyboards can improve how you play not only for the more tactile feeling but also from higher pooling rates (the rate of the "pulses" that is talked about at 5:15).

@@naturegirl1999 The polling rate is how often the keyboard sends data to the computer, so response time can be faster. This can be hundreds or thousands of hertz.

[@iFireender]

@@naturegirl1999 as @DiskPartition said, it's the USB side of things. Keyboards don't just send data as they get it, but they get asked by the computer x times a second, where x is the polling rate, "Hey, any new keypresses?" That has nothing to do with the switches of the keyboard, rather, just the control electronics.

As someone who has a mechanical keyboard, his information about mechanical keyboard is incorrect and incomplete and I feel he should have done a bit more research since a lot of information about mech keyboards are out there since the pandemic, from Tahea Types and Switch & Click.

[@ManvendraSK]

Mechanical keyboards are blessing. Writing this from a Keychron K8 Pro Brown Switches.

[@oatmilk9918]

Wonderfully produced video as always, but there are some errors/incorrect definitions worth noting; 1:14: The 104 'keys' are actually 'keycaps'. 1:24: The rubber dome sheet isn't under the keys, it is the keys (the actuation mechanism). 1:41: At the start you mention the cost of wired office keyboard, but are now discussing a wireless one which isn't a big deal, but a little misleading. 2:24: I'd phrase it 'when the user presses down on the 'keycap' or 'when the key is pressed, the rubber dome collapses'. This is an issue of calling the keycap a key 5:23: (might be incorrect) Would have been good to explicity call this polling rate and give the frequency in Hz. 5:27: I could be wrong here, but scanning is constant. You can't start scanning when you detect a key because you need to be scanning to detect the key in the first place. 8:05: Not all of them click, but given the target audience this makes sense. 8:12: Ironically, you call these keycaps on the mechanical keyboard but not the membrane one. 8:16: An unfortunate side effect of using Cherry MX blues as the example switch is that this slider design is unique to click-jacket switches and isn't representative of linear, tactile, and other clicky switch designs. The slider in MX blues is more commonly called a 'click jacket' because it's separate from the blue stem and pole. 8:53: This is just incorrect. The leaves contacting each other is not the source of the clicking sound in any MX-style switch. The actual souce of the click is the click jacket hitting the bottom housing. The pole hitting the bottom housing creates that 'clack' sound. 9:04: You also actually never explained why this switch is tactile. The animation shows it, but it is not explained. 9:00: Again calling the keycap a 'key'. 9:11: The stem and slider in MX blues is actually separated to create hysteresis. What you described is travel distance to actuate the switch, which all MX-style mechanical switches have (typically around 2mm). 9:37: Eh, I would argue most rubber domes are more tactile than MX blues. 9:40: The keycap hitting the rubber dome isn't the source of tactility, the collapsing of the rubber dome is.

[@TurboTronics11]

I came to know about this channel through Arduino forum. When I was very much doubted about how the very so small things work in SoCs and ICs. One of the people sent me a video explaining all this, as the video ended, I just blasted that subscribe button! The thing which people learnt in colleges, I know now only when I am just 15 years old!

[@Metalrasputian]

This was an awesome video! I think one thing to note is the specific mechanic switch type you showed was a clicky switch, which is not the only design regime. There's generally two other mechanical designs (which are separate from new hall effect switches as well!) The slider present in these switches is separate from the stem as they're intended to "Bottom out" the slider separate from your key stem. That's used to create a tactile AND audible feedback for when the actuation occurs. Which is why typists prefer that switch. However, linear and tactile switches are different. The "slider" portion is actually a part of the stem, it's all one piece. For linear switches, this means there's no tactility aside from the stem bottom and topping out, so no feedback on when the leaf springs makes contact. This is because there is no valley in the stem's point of contact with the leaf spring. It just slides past the leaf spring smoothly. Tactile switches use the same valley to engage the leaf spring to give you a tactile indication of actuation but no audible "click" feedback, since it's all one piece and that slider doesn't slam into the bottom of the switch housing. Again, great video! The animations were superb.

[@betrp]

[@Lishtenbird]

The "mechanical keyboard" part is so narrow that it can misrepresent this type of device to viewers who don't know anything else about them, and will perpetuate the old myth about mechanical keyboards being incredibly overpriced without offering any benefit in return. "The switches are soldered in." It is not a defining factor - they don't have to be, most enthusiast boards would offer hotswap sockets, and many people won't even consider a non-hotswap board these days because swapping switches for a different feel (or to repair) is a major selling point of mechanical keyboards. "It has LEDs." It is not a defining factor - not all mechanical keyboards have LEDs. Most enthusiast keycaps are not shine-through in the first place. The switch pictured is a "click jacket" type of clicky switch - incidentally, the switch with the worst reputation in the community. There are physically different clicky switches with better sound signatures, but more importantly - most prefer linear or tactile switches that do not intentionally produce a click, and offer a feel different from membrane keyboards, desirable both for gaming and typing. There are also "silent" switches which are even quiter. Mechanical keyboards can make less noise than membrane keyboards - clicks are not a defining factor. And sure enough, switches also come in low-profile variants as well. And I'm not even talking about game-breaking analog switches, like on Wooting boards. To drive the point home: one of the common budget keyboards is a Tester68 (no LEDs, not soldered, 68% layout) with Gateron Milky Yellow switches (linear, so not clicking) and XDA PBT keycaps (not shine-through, likely white). It's still plastic and tray-mounted, but has silicone and foam that dampens the sound. And it's about $50. Nothing was said about different layouts that mechanical keyboards offer, replacable keycaps and keycap profiles, PCB/plate mounting types, polling rates, or programmable firmware (QMK). Yes, technically this video - based on the script and the thumbnail - is about comparing a dirt-cheap basic keyboard to one that costs 50 times more... but it's also titled "How do computer keyboards work?", which is a way more general and neutral topic. Given how effective this channel's 3D work is, people may consider the information presented to be equally flawless, yet as I've noticed several times - it is not. So, if you made it this far into reading this comment - just be aware of that fact when watching these videos.

[@gabrielv.4358]

everything you said is correct. But the most good keyboard is the one you buy and use it till it breaks. There's no fun in trying to get the best keypads when YOU can make the "fail point" be the best with training, and a lot of it.

[@someonestolemyname]

Yeah I do think these problems should be addressed. It isn't like he doesn't make half hour long videos, but maybe he wants to split it into a series? Something critical missing is the n-keyroll over, I think it is a fair point to bring up this problem since it affects gamers and fast typists. I also think he should mention that there are different types of switches out there, I think optoelectric and hall effect switches will get more popular, and they seem to perform better and last longer.
