How do Computer Keyboards Work? 🤔⌨⌨🛠

I am a Computer Engineering Student, I wish this is how our professors visualize and teach us electronics

The production level is amazing and yet very underrated

The editing and visuals in your videos are superb. Thank you for sharing such informative and high-quality content.

As always incredible level of animation, is it possible to make a behind the seat video where you explain how your animations are made, how long it takes etc. I think it would be really interesting for the audience.

Love it😎

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.

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!

You sir are a a real contributor of knowledge to the world. Your videos should be standard material in universities :) Complex topics explained in an easy, understandable and awesome visualized way! Keep on going, THIS is what youtube really needs, not the 1000th channel about some crap....

Lovin the narration, and seeing the visuals and graphics improve from your first video is actually inspiring me to keep learning and get better.

I am a CS student and this is really fascinating to watch 😄 I always thought how all these keys can be taken in account with such small amount of input lines ..the concept was matrices was amazing and inspiring

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.

This is one of the few channels where I don't skip the sponsor segment. This is all super fascinating and I love to learn about whatever. Literally whatever. As long as it is in this format. Sent from my mechanical keyboard.

I really appreciate this channel. It is too brilliant.

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.

what took me half a term to learn the basics i learned in 10 minutes from this channel. Keep it up!

This videos feels both like an orgasm to the brain by finally understanding all this tech to its finests details, and an orgasm to the eyes. Those animations are beautiful, smooth and so close to real... I can't believe people can access this for free...

I would love if you guys did a video like this that shows us how you make these kinds of videos. Like how you go from getting the physical item and how you break it down and model it on a computer. That would fascinating!

i just amazed to see , what a marveous 3d editing ? how much efforts are inserted to make this topic cleareley understandable. Thank you for making such educational video for free .

The amount of effort and quality dedicated to these videos is awesome, thank you!

This video is so good. Explaining regular simple yet very complex stuff that basically everyone uses at these detailed explanations, is chefs kiss :)
