Their video on YouTube, in English: https://www.youtube.com/watch?v=9vW12gQ4Klc

Okay I must say, the production quality of that video is insane.

Feels like HTX blew up out of nowhere with a ton of long form content at once, but they were huge in Chinese social media already, and finally decided to start translating previous content to english and uploading to Youtube.

My family and I binged a few of their videos. They’re so good

Oh nice, these are the guys that made the auto-aiming trash can!

I'd watch a video about the making of this video.

From their youtube channel description:

> Our goal is to create fun and engaging videos.

I wonder whether they are more into video-making or tech.

Yes.

I've been watching them in Chinese for a while. Their video production evolved through the years by leaps and bounds. Their technical skill also skyrocketed. But it started as a channel with technical reviews and some DIY.

If you want to try to watch their videos with AI translation, you can try this: https://space.bilibili.com/163637592 For example, an artificial flower made of memory metal: https://www.bilibili.com/video/BV1gN411M7kh/

That looks really interesting, but there's a ton of text flying over the video and it's making it hard to actually see what's going on in the image. Is there a way to disable that?

Yes, you just need to click on the button with the "弹" character right below the video (it's appropriately called "barrage of bullets").

Agreed! Check out "scrubby" video: https://www.youtube.com/shorts/bLyZ7gkurv4

The wholesomeness and ingenuity made my day!

Does anyone know which keys/switches out there sound like this one?

It's got a soft cheery non-intrusive sound that I really like compared to the usual louder mechanical keys/switches that I hear in videos.

I recently learned that it's not just the switch, but also the gasket, so the switch plate material, the foam layers and even the keycap itself. I built two different split keyboards recently with the same simple Kailh box red v2 switch and they sound and feel completely different just because of the thickness of the switch plate and the type of keycaps I use.(check this for example https://www.youtube.com/shorts/HIldaxljpzc )

You can check if you find the switches colors here(it looks like an Akko purple pro, but not quite) https://keeb-finder.com/switches

Whereas rtings has a filtering list that also has sound profiles in the review pages.

Thanks for the info. A split keyboard sounds awesome.

You can get really cheap boards on taobao, for sofle, lily58, corne(all 3 are open source/open hardware) keyboards. You can of course also get prebuilt ones with or without switches for cheap if you want to. But in today's world, if you have tools and access to a 3d printer you can get a board for a few bucks some components and finish the whole thing with good switches and keycaps for 20-30 dollars.

It's a fun experience, and a nice reason to play around with SMD soldering techniques. I had my daughter (4 years) solder the hotswap sockets.

Worth checking out the miryoku layout, which is optimized for small keyboards, where I recently added sensor bindings for ec11 encoders[1].

The sound is described like creamy or thocky.

You can get aula f75 for cheap, arround 50$, there are plenty of sound tests on youtube as it's very popular.

I got that version and I am happy, but if I was to buy a new one I would get the full size f108 because it's important for me to have distance between arrow keys and other keys. And tbh I would just get an apple keyboard or something similarly slim because it's more confortable for me. However for thicc (mechanical switch) keyboards, aula f75 has great specs and sound at a very good price.

Thanks will check out the aula 75

Best keyboard I have very used was at a random data center and I would swear it was using alps switches. They feel more like snapping a glass rod.

Lube them manually (by yourself or someone else)

I wonder what issues they ran into with using the entire keyboard as a mouse.

Same, looks like an amazing idea.

I'm assuming it's too heavy and has too much contact surface (so more friction), making it too hard to glide smoothly.

There's probably something with the position of the hand when you move the mouse as well. At least I seem to be moving mostly the wrist when I use my mouse, meaning that my hand and forearm are not always aligned; without this alignment, I feel there's more strain on the wrist when typing.

my imagined device has the hand a bit more vertical, which would give more leverage for moving the device around.

Could you do a thing with magnets where you have a special mousepad as well with the pad being all one pole pointing up and the device the same pole pointing down?

Also my imagined device would not need the full keyboard, just the full right side of a qwerty keyboard.

I'd also guess fatigue. Pushing around that huge thing constantly

Put keyboard in perfect ergonomic position on the desk, move mouse, now the keyboard's in a terrible ergonomic position.

Also you have to keep a much bigger area clear for it.

I imagine it's uncomfortable to grip since you need to be careful to not press a key doing so. Since you can't rely on fingers much for grip, you could put more force pressing downward with your wrist but that would also add friction with the table. Mice are small enough that you can fit your hand around it, but a keyboard is large and flat.
