If he has an iPhone, it probably won't show IR light. I've tried with friends' iPhones and it never worked. Looking at the very same TV remote or surveillance camera using my Android smartphone's camera always showed the IR light - the fruity phones I've tried never did. Assuming the TV remote had good batteries and was in good working order or the surveillance camera was in night mode. Ditto for elevator door light curtains. Where I live, elevators are required to have light curtains between the doors and typically, light in the IR spectrum is used. If an object breaks the light curtain between the elevator doors, the doors either remain open or, if they are in the process of closing - they stop and re-open. It is a safety requirement. Most elevator companies enable a feature called "nudging" whereby after a preset amount of time, even if the light curtain is broken, the doors will still attempt to close (albeit with reduced force, I think). This is to prevent someone from holding an elevator indefinitely while other people are waiting (on other floors).
Not having any "cellphone" (or any gameboy), I would simply use one of my old digital cameras for that type of task. Their sensors see infrared too, of course.
@@frederickevans4113 What? You mean iPhone cameras don't pick IR light? Why is that? I thought ANY camera could do that. Even my ancient VHS-C camera from the early 90s could pick up IR lights from remotes.
@@OMA2k I think the fruit company put a filter on their cameras, either a physical one in the camera's lens, or a software one in the image processing. It might be a safety/modesty thing following the Sony camcorder IR nudes/semi-nudes from the late 1990s. Going purely from memory, please research it. Sony had introduced a feature called "Night Shot" into their line of camcorders 📹. It included IR illumination to help brighten night time video recording. According to the story, no one at Sony tried it in daylight. In direct sunlight, there was enough IR light (from the ☀) that the camera could see through a single layer of clothing. After months on the market and millions of these camcorders had shipped, Sony was inundated with requests to explain how to use the x-ray vision feature. When Sony tried to issue a recall, most individuals and many stores were less than enthusiastic to return the camcorders. The next version Sony released still had the "Night Shot" feature, but it was disabled in direct sunlight. If I remember the story correctly. I don't know for sure, but I suspect that the Sony camcorder story might have influenced the fruit company to filter their mobile device cameras.

@@GoldSrc_ People have search results 'tailored' to them by Google. What you see - even at the same time with the same search - is most likely entirely different than what they see.
Regarding reading mouse data, just go into anonymous mode and google "arduino mouse camera" and you find plenty of results along these lines, which work faster that the one presented here. @@ProGamer1515 I've seen Google not finding some obvious things, but not sure it tailors the results that much to user profiles, usually it's things it just doesn't index properly for anyone or jumbles it with many other unrelated things as to make the results useless. But that's not the case with this in my experience.
You could save the image after each tiny movement and then compose all the saved images into animation. Viewing the animation will be more logical to understand what the mouse "sees"
You missed the problems with the Mouse Systems pad optical mouse. I know you couldn't try it, but it does not act like an optomechanical mouse even if the way it measures movement is technically similar. The optomechanical mouse moves in the orientation of the mouse. The Mouse Systems pad optical mouse moves in the orientation of the pad, which meant that while it was very accurate, turning your hand any amount, as you do naturally, or having the pad at an incorrect orientation would cause the mouse to move in an unexpected direction. For most people, moving in the orientation of the mouse feels more natural. You could work with it when you had to like on a Sun workstation, but I had little patience. Using a ball mouse and dealing with the cleaning of the rollers was easier.
Interesting. I never really had that issue when I used such a mouse back in the day. I am sure it happened but I think is similar to the lack of issue I have with the up and down direction of a USB. Just something a lot of people encounter that I never really did and the few times I had a slight issue it was so slight and took so little time to correct that I forgot about it. It may be that I also had a more advanced later version of the grid pad optical mouse. Something that may have used grid for the sensor but was more akin to a modern optical mouse. It was such a long time ago for me, so I am not sure.
A lesson re-learned years later with the Apple puck mouse - the mouse with no orientable shape. A courageous endeavor in pushing the boundaries of form over function!
However, you could really annoy the person next to you with a 90s Sun workstation by moving the mouse mat round 90 degrees. So now, up with left and left was up. Small pleasures but you got to find happiness where you can.
Wow, what a packed and super interesting episode. Last year, I ran into those opto-mechanical solution inside a Mac ADB Advanced Gravis MouseStick (I) and had to diagnose it before it started registering movement. I made a lengthy thread about it in the allaboutcircuits forum. Basically, the light wasn't picking enough light because of scratches in the plastic film on plastic film contact inside the wheel between LED and photoresistors. I had to up the voltage feeding the LEDs to make the whole sequence trigger. Most people owning these joystick have developed this problem over time so these 'duds' are unfortunately getting sold on eBay and most people don't realize it's an easy fix by turning a potentiometer for a bit. I went further down the rabbit hole this year by getting inspired by a custom thumbstick joystick getting interpreted by a very small Arduino which sent back the same kind of quadrature data, but digitally, to an old Macintosh serial port, so that it could replace the mouse in a Mac Plus, 512k, 128k or even Lisa. I mimicked the design and tried to improve on it while also making a gamepad case, 3d printed. Our designs and choices are documented in the hardware section of 68kmla forums.
@@theaveragecactus He's probably supporting the 8-Bit Guy on Patreon. I mean, Technology Connections actually releases videos a day early to Patreon supporters.
Back then, it was always the rollers. Now, many of the balls have degraded to the point where the rubber has gone ever so slightly stiff. Just enough so that it doesn't quite grip the rollers properly, and you get tracking issues. I've found that the Microsoft Serial Mouse 2.0/2.1 are still fairly reliable.
@@mare65 I was wondering why they did 15x15 instead of 16x16. Maybe a reserved or null value? Or maybe it was easier to have a zero column (and row) where everything was offset relative to it. I don't know anything about engineering but this is fascinating.
You probably have an Android smartphone. All my friends' fruity smartphones I've tried that with have failed to see the IR light. I have a Samsung Galaxy S7 and it sees IR (as did the GS5 and GS2 I had before). If you have a smartphone capable of seeing IR, that is one way to check the batteries in your TV remote. Pressing buttons: good batteries = blinking light, bad batteries (or faulty remote) = nothing.
I figured out all by myself that it was the wheels getting dirty. A fingernail did wonders for scraping gunk off. SOoooo satisfying to remove that stuff.
Ya me too and then I taught the other kids and teachers that trick. Because teachers would only have like 2 or 3 extra computer mouse in the class, and when a whole bunch of them had gummed up some of us would get stuck with gummed up ones. Now that I think about it, the teachers sent the computer mouse back to IT for maintenance/repairs because hardly anyone knew about cleaning the rollers...
@@spacefightertzz The optical equivalent, getting a cat, dog, or arm hair stuck in front of the eye, and that's more frustrating to deal with, harder to get out, and lacks that sense of accomplishment. On the plus side, it isn't as sure to happen as gumming balls.
Your videos turn a topic which is very confusing to understand for most people and makes it simple to understand. Thank you David for making such interesting content, and explaining it really well.
I recently cleaned a few of mine up - definitely a flashback. Did you know, the balls in Microsoft mice, when the rubber coating is removed, fit into paintball guns near perfectly? :D
3:58 If i don't remember it wrong the direction of the movement was always how the mouse pad was placed and not how you hold the mouse. You could turn the mouse the other direction but the mouse pointer moved up even if the mouse cable was against you.
7:58 "Now you'd think all I need to do now is read register B here, which is pixel grab." No, no I did not think that, let alone think at all when the data sheet was displayed..
Benjamin Lum its actually not too difficult to understand, its all laid out on the datasheet, for example take the register Motion at 0x02, so since its using a byte it has 8 bits, below the chart with the registers it lists in detail the bits and the fields and what they mean, like for Motion it says bit 7 (it starts at 0 so 7 is actually the 8th bit) is MOT which it says is motion since last reported which returns two values, 1 or 0, 1 meaning motion has occurred, 0 meaning no motion, with the rest of the bits reserved. What this tells us is that you can read at 0x02 and the 7th bit will tell you whether or not motion has occurred. If you’re interested in reading more for yourself you can find this particular datasheet at media.digikey.com/pdf/Data%20Sheets/Avago%20PDFs/ADNS-5030.pdf
Pretty neat that you wrote your own program to poll the sensor, though there are already people who have done this. There's even a program called mousecam which lets you more or less "scan" with the mouse, so you can read larger areas by moving around the mouse.
Every time I catch myself feeling too smug about my OG nerd skills & knowledge, I come to your channel and get humbled. Thanks for your great videos and for documenting the beginnings of what we take for granted today!
Great video. I was the nerd in the computer lab that could do 'magic' things to mice by cleaning the rollers. Some of the kids used to get so worried when I'd pop the ball cover off and they'd see a flash of the circuit board.
I had a Mouse Systems Amiga mouse back in the 90s - absolutely brilliant at the time, so long as you kept the mouse perfectly straight! Angle it a bit and the pointer starts to do the Lambada.
That's how we know it's a documentary by David: He starts with explaining ______ really well and draws some diagrams and other useful graphics before starting to cut some wires, solder stuff and write a basic program just to demonstrate something simple.
You are a very clever man, being able to hack in to the camera on that mouse! Pretty cool how you've got all this vintage gear as well. A lot of it must be hard to come by, (the stuff that still works anyway).
Little bit of trivia for the 90s kids: The analog sticks on the Nintendo 64 controllers used optical encoders much in the same fashion as old ball mice meaning they were mostly digital as the encoders can only detect a set distance from the assumed center in so many exact increments. But by being able to detect so many small increments of movement, it essentially "emulated" true analog control as far as the end user was concerned. Probably the only thing that gives it away is the very subtle "ratcheting" feedback you can feel when rotating it, that's the plastic teeth on the encoder discs.

@@OMA2k I think the fruit company put a filter on their cameras, either a physical one in the camera's lens, or a software one in the image processing.
It might be a safety/modesty thing following the Sony camcorder IR nudes/semi-nudes from the late 1990s. Going purely from memory, please research it. Sony had introduced a feature called "Night Shot" into their line of camcorders 📹. It included IR illumination to help brighten night time video recording. According to the story, no one at Sony tried it in daylight. In direct sunlight, there was enough IR light (from the ☀) that the camera could see through a single layer of clothing. After months on the market and millions of these camcorders had shipped, Sony was inundated with requests to explain how to use the x-ray vision feature. When Sony tried to issue a recall, most individuals and many stores were less than enthusiastic to return the camcorders. The next version Sony released still had the "Night Shot" feature, but it was disabled in direct sunlight. If I remember the story correctly.
I don't know for sure, but I suspect that the Sony camcorder story might have influenced the fruit company to filter their mobile device cameras.

You missed the problems with the Mouse Systems pad optical mouse. I know you couldn't try it, but it does not act like an optomechanical mouse even if the way it measures movement is technically similar. The optomechanical mouse moves in the orientation of the mouse. The Mouse Systems pad optical mouse moves in the orientation of the pad, which meant that while it was very accurate, turning your hand any amount, as you do naturally, or having the pad at an incorrect orientation would cause the mouse to move in an unexpected direction. For most people, moving in the orientation of the mouse feels more natural. You could work with it when you had to like on a Sun workstation, but I had little patience. Using a ball mouse and dealing with the cleaning of the rollers was easier.
Interesting. I never really had that issue when I used such a mouse back in the day. I am sure it happened but I think is similar to the lack of issue I have with the up and down direction of a USB. Just something a lot of people encounter that I never really did and the few times I had a slight issue it was so slight and took so little time to correct that I forgot about it.
It may be that I also had a more advanced later version of the grid pad optical mouse. Something that may have used grid for the sensor but was more akin to a modern optical mouse. It was such a long time ago for me, so I am not sure.
Weird I have a Sun 3/80 workstation I use quite a lot and I never even noticed. Gonna have to try and get it to mess up now lol
A lesson re-learned years later with the Apple puck mouse - the mouse with no orientable shape. A courageous endeavor in pushing the boundaries of form over function!
I wondered if this exact same issue would arise when he explained how it worked. Thanks for confirming that this is indeed what happened!
However, you could really annoy the person next to you with a 90s Sun workstation by moving the mouse mat round 90 degrees. So now, up with left and left was up. Small pleasures but you got to find happiness where you can.

Wow, what a packed and super interesting episode. Last year, I ran into those opto-mechanical solution inside a Mac ADB Advanced Gravis MouseStick (I) and had to diagnose it before it started registering movement. I made a lengthy thread about it in the allaboutcircuits forum. Basically, the light wasn't picking enough light because of scratches in the plastic film on plastic film contact inside the wheel between LED and photoresistors. I had to up the voltage feeding the LEDs to make the whole sequence trigger. Most people owning these joystick have developed this problem over time so these 'duds' are unfortunately getting sold on eBay and most people don't realize it's an easy fix by turning a potentiometer for a bit.
I went further down the rabbit hole this year by getting inspired by a custom thumbstick joystick getting interpreted by a very small Arduino which sent back the same kind of quadrature data, but digitally, to an old Macintosh serial port, so that it could replace the mouse in a Mac Plus, 512k, 128k or even Lisa. I mimicked the design and tried to improve on it while also making a gamepad case, 3d printed. Our designs and choices are documented in the hardware section of 68kmla forums.

Ah, the memories of having to periodically clean the crud off the rollers when the mouse stopped working.
And all the tech support calls for the same!
Ah, the old days of cleaning the rollers using a Bic pen cap...
I still do. Using a logitech M-BA47 .
I've heard of people collecting belly button lint and earwax. I wonder if somebody out there collects mouse ball crud. 🤣🤢
Back then, it was always the rollers. Now, many of the balls have degraded to the point where the rubber has gone ever so slightly stiff. Just enough so that it doesn't quite grip the rollers properly, and you get tracking issues. I've found that the Microsoft Serial Mouse 2.0/2.1 are still fairly reliable.

@@mare65 I was wondering why they did 15x15 instead of 16x16. Maybe a reserved or null value? Or maybe it was easier to have a zero column (and row) where everything was offset relative to it. I don't know anything about engineering but this is fascinating.
I'm glad this video blew up in many people's recommendations.. have been a follower since forever!
4:30 You don't need a Gameboy camera for that. Phone cameras show infrared light as well. I tried it with the LED of my TV's remote controller.
You probably have an Android smartphone. All my friends' fruity smartphones I've tried that with have failed to see the IR light. I have a Samsung Galaxy S7 and it sees IR (as did the GS5 and GS2 I had before).
If you have a smartphone capable of seeing IR, that is one way to check the batteries in your TV remote. Pressing buttons: good batteries = blinking light, bad batteries (or faulty remote) = nothing.

Ya me too and then I taught the other kids and teachers that trick. Because teachers would only have like 2 or 3 extra computer mouse in the class, and when a whole bunch of them had gummed up some of us would get stuck with gummed up ones. Now that I think about it, the teachers sent the computer mouse back to IT for maintenance/repairs because hardly anyone knew about cleaning the rollers...
@@spacefightertzz The optical equivalent, getting a cat, dog, or arm hair stuck in front of the eye, and that's more frustrating to deal with, harder to get out, and lacks that sense of accomplishment. On the plus side, it isn't as sure to happen as gumming balls.
How did people think it was the balls? You open it and take the ball out, the rollers have a ton of junk of them and the ball is spotless.

7:58 "Now you'd think all I need to do now is read register B here, which is pixel grab."
No, no I did not think that, let alone think at all when the data sheet was displayed..
Benjamin Lum its actually not too difficult to understand, its all laid out on the datasheet, for example take the register Motion at 0x02, so since its using a byte it has 8 bits, below the chart with the registers it lists in detail the bits and the fields and what they mean, like for Motion it says bit 7 (it starts at 0 so 7 is actually the 8th bit) is MOT which it says is motion since last reported which returns two values, 1 or 0, 1 meaning motion has occurred, 0 meaning no motion, with the rest of the bits reserved. What this tells us is that you can read at 0x02 and the 7th bit will tell you whether or not motion has occurred.
If you’re interested in reading more for yourself you can find this particular datasheet at media.digikey.com/pdf/Data%20Sheets/Avago%20PDFs/ADNS-5030.pdf

Pretty neat that you wrote your own program to poll the sensor, though there are already people who have done this. There's even a program called mousecam which lets you more or less "scan" with the mouse, so you can read larger areas by moving around the mouse.

I've always wondered how these mice worked. Thank you!
You get reminded of how old you are when you remember thinking nothing when taking out the mouseball to clean it.
Little bit of trivia for the 90s kids: The analog sticks on the Nintendo 64 controllers used optical encoders much in the same fashion as old ball mice meaning they were mostly digital as the encoders can only detect a set distance from the assumed center in so many exact increments. But by being able to detect so many small increments of movement, it essentially "emulated" true analog control as far as the end user was concerned. Probably the only thing that gives it away is the very subtle "ratcheting" feedback you can feel when rotating it, that's the plastic teeth on the encoder discs.
4:41 Wow, I think you just fixed a broken pixel in my eye!
This is why I watch you, David. I learn so much about how things work and the evolution of things that I use everyday.
