It is undoubtedly a very meaningful thing to let more people understand the internal structure and working principle of various electronic products in this straightforward and clear way. We are proud to sponsor this high-quality science content. ❤
I, as a smurfy computer engineer, really appreciate, thank and wish you guys all the best on the great and impactful help that you give for such content creator and, for us, the viewers Hope you guys grow and bloom like never before, keep up the noble work!
I get so excited when these come out! As a current engineering student, I love seeing devices and breakdowns that actually apply to my everyday life and aren't just outdated technologies. Keep up the amazing work!
You do not know how much this channel means to me. I love learning how things work, inside and out, and the detailed visuals and easy to understand voiceover make it so much fun to learn something new. Please continue to produce this amazing content!
Your videos have astounding detail. I cannot believe how much effort you put into them. Even the choice to spend time showing how the electrons might look as they move across the plate at 4:50 - the kind of plinko-effect, rather than just simply flipping the red and blue. Truly remarkable. Thank you for such quality work.
I'm not an engineering student or studying anything related to science, but I'm always excited to discover how things I use everyday work in detail and in a simple manner 🤩 love the videos
@@InternetUser999 I have a Logitech MX Anywhere 2S, and it is by pressing the scroll wheel itself that engages/disengages the smooth/stepping mode of the wheel, there is no motor but a simple mechanical latch. The button behind the wheel is its own separate button, with no relation to the wheel.
@@PushyPawn Its different on every mouse. I used to have the standart MX Anywhere 2 and pressing the scroll wheel also enables the fast scrolling mode. I now have the Logitech G903 and it has a seperate button under the scroll wheel that enables fast scrolling and the scroll wheel click works as normal.
@PushyPawn @David K I actually have two buttons on mine. One behind the scroll wheel, and one even further that changes the DPI between five settings. And then there are the two custom buttons on the side that I can configure to do whatever I want
The effort that goes into this channel continues to impress me, I'd never thought that something so seemingly simple could be so incredibly well thought out in its every detail. Well done, thank you so much for doing these videos!
I actually was searching for a mouse that I can trust. At the moment I have a Genius NetMouse Wheel/PS2 but I would like something with a USB connector and an optical scrollwheel (just like the NetMouse) to carry around in my backpack. Couldn't find one just yet :(
honestly i think this was true even 5 years ago, but competition is extremely fierce and you now see tons of very affordable and cheap mice, typically targeted at gamers, with features that you only normally see in expensive ones. just look at amazon's best sellers and see their features and price point. maybe it's true that a lot of them still use simpler designs, but likely not 95% of mice.
@@BattousaiHBr Can you give several examples of better mice? AFAIK even top-tier gaming mice, not old by any means, like logitech g pro x superlight, razer viper ultimate, have mechanical encoders. And my current "pwnage ultra custom wireless symm 2" too.
@@WERT2025 the superlight is an exception because it's going so far in the high end side that it's "sacrificing" some performance for less weight (though i reckon they have gone through effort to still make the scroll as good as it can). other than that, there's plenty of mice with optical scroll sensors. maybe most of the expensive ones? if you've seen mice with that wheel switch that changes between stepped mode and free mode, those are all optical sensors afaik. another good indicator (though not necessarily a rule) are metal wheels.
I’ve without a doubt learned more than anywhere else from your channel. I love that you NEVER back down on detail and always seem to make everything easily digestible, love it love it love! Please do continue your great work! Computer engineering student
I've ignored this video on purpose for some time because c'mon, what can I learn about mouse wheels - they are so simple. Man was I wrong. I suspected the visuals are going to be top notch and of course they are, as usual, but once again, the level of detail around engineering solutions is in class of its own - superb!
As an adult(and uncle) I am amazed by the quality and already excited to share these with the next generation. The quality is top notch from the explanation to the visual effects.
I was changing the encoder on my old noname mouse to seemingly same type of encoder part - potentiometer. Both old and new parts looked just alike, same xehagonal hole to engage with the wheel, same 3 contact legs. But the new part didn't work. So i squished the metal tabs and disassembled both. While the new had resistive track connected to side legs from its ends, the middle was moving across it. However the original now broken part was just 3 sliding contactors separated in a complex metal shape with many additional legs that could contact with only 2 of its legs thru a rotating metal contact on the spinning part. That was very clever and cheap solution. It lasted for years and became faulty only because of metal fatigue on the contacts, those weren't pressing hard enough to the spinning metal part. It was generic white Logitech mouse and yes i managed to fix it by pressing metal tabs that keep parts together harder.
Great explanation. this difference is like the one between dual clutch and automatic car transmissions. They both do the same thing on very different ways.
I love this, I feel like I completely understand the topic. It reminds me of an old favorite (sadly, no longer active) channel called “The Engineer Guy”
I literally needed to know how a mouse scroll wheel worked, for a project of mine. I thought to myself: "Branch Education probably won't have a video like that. I was mindblown to see that exact video, right here! And, as usual, the entire mechanism was explained with absolutely staggering detail. Well done!!
The timing on this is so funny to me - I was just a few weeks ago researching how feasible it was to try and build my own gaming-level mouse from scratch. I have some very awkward hand sizes that have made it difficult to find a mouse that's comfortable to me AND that includes all of the fancy modern features with buttons in places I like. It'd be really fun to 3d print my own case & buttons, and learn how to wire up the boards and sensors correctly on my own. But learning about scroll wheels was difficult, and figuring out how to obtain PCBs seemed impractical.... you managed to cover both in ways that have reignited my interest. Thank you :)
I have two mice, the G502 which has an optical encoder, and a G102 which uses a potentiometer. The G502 still works to this day, but I had to replace the g102's encoder after 6 months of use. I didn't bother with warranty as I lost the box, and is as good as void if you lose it. Fortunately, you can get encoders shipped from China for cheap, you'll just need the right size. The encoder the G102 Lightsync uses is a Kalih 10. Fortunately, most encoders are standardized and the replacement I bought fits perfectly. I also had to replace its Omron switch. For the G502, I had to replace its middle click membrane button. It was difficult to find replacements as you have to buy it in a set and is surface mounted. I don't even have a proper hot air solder so I had to use a big a$$ heat gun to remove. I've partially melted an omron switch but it still works, and the middle click is now working.
8:18 this method has flaws though, the rubbing will wear down the potentiometer and thus cause it to break, this is unfortunately the method used by modern game controllers and is what causes the drift affect, it would be amazing if they instead used optical or magnetic sensors so they would'nt wear down
Even then there will be some mechanical component for the sticks that will eventually fail, besides, this may give some extra excuse for companies to make controllers even more expensive than they already are I think.
@@Inferryu what mechanical component? if an optical sensor was used there would be little to no wear on components, the only possible wear would be on the ratchet component but the ratchet component isn't essential for the mouse to operate
@@adrian-x5v You were talking about controllers, so my comment was referring to those, not the mouse. In any case, you still need an axle for the wheel to turn, that will eventually wear out, same goes for analog sticks, you still need a structure of some sort to allow for the type of movement they have, the sensor itself may not fail(for use at least), but the supports will still see the same use.
I was a teacher or lecturer, this channel would be something I would have suggested to the students regularly. Absolutely amazing information, narration, graphics and animation.
i only came here to verify what i already knew without actually having looked inside a mouse. i think lasers/light is best way of measuring anything really. i dunno if my idea would be harder or easier, but instead of those spokes, i'd have a pattern, similar to barcode, but with holes in them. a very simple pattern, kind of like binary. this way you'd only need 1 sensor and microchip would know the full pattern, so it would instantly know if wheels is being moved up/down and it would also know the exact position of wheel, which is not really needed, but i think that method would be easier and simpler.
Some adults should go back to school and start again. I HATED learning stuff at school - it always seemed like so much of a mission that often I didn't get the bigger picture, so I didn't get the high marks in exams. Now, though, these things that I couldn't grasp are not only grasp-able, but FUN to learn! Watching this was like watching a UFO disclosure dockie. LOVED! Thank you!
the professionality of this video is over the top, although gen Z may find difficulties understanding all this because of the way how it was explained...
Just discovered this channel few days ago. saw most of the videos and I just like it too much. I always wondered how the day to day things like this worked.
The optical method is also the one with which the analogue stick of the N64 worked. For at least 20 years now, basically every controller uses 2 potentiometers at the stick, one registering the X movement, and the other for the Y movement. The N64 design was similar with registering X and Y, but with the same optical system as explained here. It was very unusual, but not a bad design at all, since those controllers were very accurate - even the stick was wobbly like hell. Still Nintendo recognized to improve this design big time with the GameCube controller, one of the arguably best controllers to this day, also part of it's (indestructable) stick.
I know of many tracking devices without scrollwheels. 1. Thinkpad's trackpoint, is superior to any schrollwheel, because you get a variable speed, continuous space 2d scrolling device with it, the same trackpoint is the scrolling device and all you need is press the middle button which is bellow the space bar and it turns into a scrolling device, the best, because with a very long page to scroll, you control the speed with the pressure. 2. Apple Trackpads, is the next best scrolling device because it also uses the same device for tracking and scrolling just use one finger for tracking and two for scrolling, very handy but the scrolling isn't continuous if you have a very long page to scroll, you have to swipe multiple times. 3. Kensington's trackballs have a scrolling ring that allows for continuous scrolling but is not 2d, is just 1d, so is called ring but is more like a knob in the shape of a cup that holds the ball. The Kensington Slimblade allows to use the trackball itself as a scrolling device, similar to the ring but without the ring, not very accurate, this one sucks
I've been using these types of peripherals (mouse, keyboard) since the early 2000s. This is the most informative and illuminating video I've ever seen. Especially visual animations during the presentation are really top-notch quality.
The mouse wheel knows how much it is rotated at all times. It knows this because it knows how much it isn't. By subtracting how much it is rotated from how much it isn't, or how much it isn't from how much it is (whichever is greater), it obtains a difference or deviation...
Here is an idea, right after detecting the direction, and changing direction can not be instantaneous because of the inertia, we can use those 2 sensors to increase the resolution and get 96 pulses instead of 48
6:50 I have a mouse from Logitech that doesn't have a button to en-/disable ratcheting and a button below the scroll wheel assembly for middle clicks but it rather has a button on the position showed in the video that does middle-clicking and pressing down on the wheel activates a mechanism that turns on/off ratcheting. That also works when the mouse is not powered. The follower and the ridges on the wheel for the ratcheting are the same though, just toggled on/off differently.
If this channel continues on like this, one might be able to rebuild the entire high-tech civilization from the stone age just using it's videos as guides.
Mice can work well without a scroll wheel as long as you are used to it. For example, one mouse that I can think of without one is the Zaunkonig M1K. A very niche mouse, but shows that there is a market for something like that.
i used a tons of cheap mouse but when i started earming i bought a Logitech G 402. after few years of use i opened the mouse to clean dust, saw this scoll wheel in amazement that is a optical one. cheap mouse never lasted more than 3 months but g402 is with me for 5 years. with no damage to its internals. and this video cleard my curiosity of optical scroll wheel.🤗👍
Very interesting, my company uses hall sensors for fans with multiple speeds tracking and failure signaling. I wasn't aware of a mouse with auch similar usage of the hall sensors. Great presentation!
Another use for them: Keyboard switches. Though they tend to only be used for ones that need extreme reliability (billions of keystrokes), such as aerospace applications.
I can top the weirdness with my *_Saitek_*_ X65F H.O.T.A.S._ that uses Strain Sensors on the Sticks X, Y & Z Axis to recognize their input *_WITHOUT_* the Stick actually moving even the tiniest bit. Super neat system allowing for highly accurate and immediate movements. The only downside with it though is it causing my PC to not being able to go to sleep when I place it on or even just near my *_Logitech_*_ PowerPlay Mouse Mat_ as the Magnetic Charging Coils in the Mat will trigger a signal response in the Stick thus waking up the PC.
Perfect. I am trying to watch the video while having the extra, noise and chaos from outside in the middle east swamp turkey but this video takes all my attention and focus. Thank you very much.

i used a tons of cheap mouse but when i started earming i bought a Logitech G 402. after few years of use i opened the mouse to clean dust, saw this scoll wheel in amazement that is a optical one. cheap mouse never lasted more than 3 months but g402 is with me for 5 years. with no damage to its internals. and this video cleard my curiosity of optical scroll wheel.🤗👍
love the way you say wheel

This is the best education chanel I have ever come accross. Thanks for all your videos.
You folks are masters of 3D
Very interesting, my company uses hall sensors for fans with multiple speeds tracking and failure signaling. I wasn't aware of a mouse with auch similar usage of the hall sensors. Great presentation!
Another use for them: Keyboard switches. Though they tend to only be used for ones that need extreme reliability (billions of keystrokes), such as aerospace applications.
I can top the weirdness with my *_Saitek_*_ X65F H.O.T.A.S._ that uses Strain Sensors on the Sticks X, Y & Z Axis to recognize their input *_WITHOUT_* the Stick actually moving even the tiniest bit. Super neat system allowing for highly accurate and immediate movements. The only downside with it though is it causing my PC to not being able to go to sleep when I place it on or even just near my *_Logitech_*_ PowerPlay Mouse Mat_ as the Magnetic Charging Coils in the Mat will trigger a signal response in the Stick thus waking up the PC.
Perfect. I am trying to watch the video while having the extra, noise and chaos from outside in the middle east swamp turkey but this video takes all my attention and focus. Thank you very much.
This channel is amazing. Very well articulated everything!
This channel is absolutely incredible
