Yeah, I managed.
Okay, so we are speaking about the famous mouse,
my computer mice, sorry.
Of the past and what to do if you can handle one today,
how can you plug it into your contemporary computer?
That's a list of some mice we explored for this talk,
not only not all of them are on the slides,
but you will have a link in the end.
And first through mice, which we couldn't try ourselves,
well, actually 1952 was the year of the birth of a trade ball.
It was developed for other systems in the Royal Canadian area,
and quickly ruined for compatibility reasons.
So, we have no working exemplars,
and we don't know how to connect it to this story.
But all other devices are much better.
You see this, 1966, the first Douglas-Angelbot mouse,
actually it's not, it's a replica from the California Computer History Museum,
but still, this one is connectable, I'll tell later.
Technically, it's really simple, it has two views.
One wheel is rotating, the other wheel is sliding,
because it's placed orthogonal.
So, when you move it left to right, one wheel rotates,
forward backward and other wheel rotates,
wheels are connected to potential emitters,
and so the voltage is changed on the team of the jack of this mouse.
So, it's technically it's an analog joystick.
I'll speak later how to try it.
If you have, probably you don't, but.
1966 is another device, which is supposed to be the first mouse,
at least it has ball.
It's more mouseish, I would say,
and it's telephone can roll to build device.
You may be surprised, but this one has open source connector.
Probably there are about 10 roll coogles in the world,
but one of them belongs to a urgen Miller,
was the reason to create a tiny,
microcontroller based dongle to connected to USB.
So, if you are from this other nine people,
go to his website.
By the way, it's a parallel mouse.
It's each encoder, mechanical encoder,
produced for a bit gray quad,
and the ball is actually both a pinpoint,
hard and a little bit.
Well, all quad, all parallel mice,
we will speak about a quad-rature devices.
Just they produce two bits gray quad, not for it.
You see XA and XB of one cardinate,
YA and YB for another cardinate.
So, they are related devices, they produce Delta X and Delta Y.
Which is much better than Android smart mouse,
which is absolute positioning device,
and if you reach the end of your table,
or if you reach the end of the rotation angle of potential meters,
you should roll it back,
which is a definite uncomfortable,
and moving to popular mice,
which you can find yourself.
The first, actually, available to purchase,
was zeroed out of mouse.
It was developed by two engineers,
Bill English, the one who helped Andrew Bartow,
create his own first mouse, and Jay Kohle.
They are rather funny devices.
By the way, you see here the contact encoder,
and yeah.
You see here contact encoder with few wires,
connecting to this, sorry,
to this thin pound-looking disk,
which rotates, and these wires have different lengths,
and they produce gray quad.
The mouse was terrible,
because well, all dirt and other things from the ball,
where easily sitting on this disk,
and no contact,
but from the connecting point of view,
it's a typical quadrature mouse,
and you can easily connect it with Arduino.
I personally prefer the Amiga converter,
with just different pin-out,
but a lot of other converters do exist.
And because those mice were terrible,
zero-scrated, first optical mice mouse in 1981,
which had matrix of four-by-four optical sensors,
which was twice cheaper than the original one,
a mechanical mouse was $400 in 1970s,
by a car or by a mouse.
You can choose.
Well, you know, four-by-four matrix is not very big
from...
So, it needed some pattern on the mouse pad.
Actually, mouse pad was paper.
Great, provided by zerox,
or just for the quartied by end users.
This is plain quadrature device,
nothing to speak about about connecting it,
connected with the same.
In 1982, the first optical mouse
from Logitech, or you may say the bra,
the bra, watchmaker company,
and two United States entrepreneurs
who later became Logitech.
They used live beam instead of these contact wires,
so dirt was not such a big pain.
And parallel versions are easy quadrature mouse.
Once again, but they have dedicated converter,
just for this mice.
Not bad converter, by the way.
A serial one, well,
actually are supposed to exist,
but I never saw them.
But zero interfaces little bit different as you may get.
You have only one wire,
and several bits of a package
represent the same delta x and delta y.
And the first serial mouse, you can probably try,
is one of the mouse systems.
As simplified optical mouse,
created by a student, Stephen Kursch,
in California, who used reflective mouse pad
with longitudinal and transverse lines,
visible in different light.
One in optical range,
and another one is in infrared range.
So it demanded special mouse pad,
but it was even cheaper.
It didn't use this for by four matrix by zerox.
The next one is absolutely not interesting
from connection point of view.
It's Apple Lisa Mouse.
Everyone likes it.
Everyone knows about it.
It even has its dedicated converter,
but it's still a prototype device, nothing to speak.
This one is really interesting.
It's a first major order from Logitech,
mouse, they created for QLED Packard.
It's interesting because it's, you know,
a Daisy chain bus, HP Hill,
which is, which,
recently, was included
into the firmware of open source keyboards.
The converter for these QLED Packard keyboards
and mice was included.
So you may remember these ergonomics
is at split keyboards.
The firmware, what QMK and TMK
has also, from where,
a call to run these mouse.
Plug it to USB via some Arduino scene, I think.
It frankly speaking, it's a huge advantage
because the protocol is rather complicated.
The same here, mice went back
to analog joystick simulation.
For strong reason,
just home computers had no communication port,
had no mouse port, but they had port for a joystick.
And so you have a few funny devices.
Some of them have gears.
Some of them have something like bell drives
and look completely distinct on location side.
I personally like them.
For more expensive computers without
communication port,
there were other devices like this trackball,
which was included into the keyboard port.
And actually, he was listening to the keyboard
and sending it and when you rotate the ball,
it was sending a QSOR key key presses.
Funny moment.
Yes, you could chat with it,
open text editor, type something,
it listens,
and sometimes answers you in your own text editor.
And 1986 is one return to mouse based on wheels,
like Andrew Bartz,
wheels are much smaller than the reason.
They thought that it will be less prone to dirt.
This one is a manager mouse,
rather simple,
and I would say rather bad,
from the construction point of view,
but jacolic rate,
it's another approach with wheels,
which are slightly,
yeah,
at an angle,
and they are rotating,
and they are placed outside of the mouse.
If the resolution would be higher,
I would say it will be real,
you know,
will think,
but this tiny wheels.
You can easily,
by the way,
connect this one to a Linux computer.
You just need to provide extra power,
because normal communication port will not power this.
And 1987,
the end of anarchy among mice,
because TS-2 interface appears,
and starting from this,
you can buy a dongle in AliExpress,
well,
not in 1987,
but soon.
And forget about problems connecting mice.
A few more devices,
just to mention,
the first ergonomic mice,
which actually copied the sending or block.
The idea of Microsoft was that people are using such blocks
for hundreds of years,
the probably it should be rather comfortable for a hand,
and it was,
from connection point of view,
it's not interesting,
by the way,
either quadrature or serial.
And,
the 1995,
almost the last mouse,
almost,
the luggage did,
remember these zero optical mouse,
and put the same pattern on the ball,
and got rid of mechanics,
and used optical sensors,
matrix just to track the rotation.
Actually,
Microsoft will soon do the same with normal mice,
in 98,
with intelligent mouse,
just adding more sensors to get rid of mouse pad.
But the last important mouse,
I would mention,
was the mouse system's pro-edges,
chrome mouse from 1995,
because,
well,
it made all mice before it legacy.
Because of the scroll wheel,
you see,
the wheel,
it's a cylinder,
but it was intended to zoom in Excel,
but people quickly understood that it's not for Excel,
but for scrolling,
and sold their revolution,
and it,
and all previous mice became,
almost useless.
So the conclusions,
surprisingly,
all,
you know, mice,
which are key turning points in the evolution of mice,
are connected to USB with some open source tools.
I,
well,
when I've started this presentation,
I actually didn't know.
I will get 100% of mice,
connected.
The most difficult parallel mice,
well,
they are known to be difficult for
IBM PC compatible computers of the past,
now are extremely easy,
because,
quadrature interface is the same.
The most tricky exotic bosses,
actually,
they turn out to be a normal
comport with additional power,
or powered by this lazy chain,
a tricky boss by keyboards.
And,
well,
a few useful links as a last slide.
The first is just the history of
a Logitech mice with really nice photos,
I love a lot.
And,
then, a few links to most important
converters,
and,
actually,
the last link,
the website with those mice,
which,
didn't fit in to 20 minutes,
but,
which we have explored in details,
and try to describe,
thank you.
That's all.
Yep, please.
This is all from personal collection,
or,
I,
first three are not.
Three are from museums,
sorry.
But, all others are...
Your collection.
Thank you.
Oh, please.
Well,
that's a difficult question,
substantially bigger than,
where I already explored.
So, on the website,
we have 50 with something mice,
and a multiplied by something.
So, yeah,
a lot of work is still to be done.
Yep, please.
All the mouse for consoles,
like my station,
or...
Oh,
yeah.
Good question, by the way.
Yeah.
The question is about some of my protocols,
which may be not supported by
a person who's converters,
like PlayStation or so on.
Good question.
I wouldn't say that zero mice
are non-connectable with open source.
No, no, no.
There are three key protocols,
which I personally don't know how to,
to convert.
I wanted only to say that mice,
which were turning points
in the evolution of mice.
All those mice are surprisingly supported
by open source converters.
Yeah.
But still writing a converter,
creating a converter on our DNA,
it's, well,
it's something,
or which still has to be done for few protocols.
Just the mice itself,
the mouse itself may be not so interesting,
but the protocol can be rather tricky.
That's the answer.
Yeah, please.
No.
I used a,
what's the reason to make some claps,
but what is the,
the protocol,
the most common thing for MY?
Ah, the question was,
what's my favorite mouse protocol and why?
Good question.
I would prefer,
quite the true mice,
because they saved me a lot of time,
and I think,
by just changing the pins,
in the Arduino sketch.
Please.
I'm going up the question
about just a story for you.
I used some of those mice,
these were in the 80s,
and especially the awful commoner.
When you're the first mouse in the 80s,
I knew a person
that I've never seen a mouse before,
and then they're able to use it
upside down.
Thank you.
Okay.
