Mouse for hacker, for gamer and DIY-maniac
While marketers write for marketers about 16 million colors of mouse illumination, gamers for gamers make devices with unrealistic sensitivity, I decided to delve into the insides of the super-duper modern mouse Roccat TYON with my
If you believe the description, then inside it settled 32-bit processor (72MHz Turbo Core V2 32-bit Arm based MCU) and half a megabyte of memory. Not only is this mouse smarter than my first computer for programming and it is more expensive than my first netbook, so the system of achievements is also built into the mouse itself.
Performance characteristics are impressive
(I don’t know if they are justified, whether they can come in handy, but still cool)
- Laser sensor Pro-Aim R3 up to 8200dpi
- 1000Hz polling rate
- 1ms response time
- 12000 frames / s, 10.8 megapixels
- Acceleration 30g
- 3.8 m / s (150 inch / s)
- 16-bit data channel
- Launch Distance 1-5mm
- Built-in tracking and distance control module
- 32-bit MCU Arm 72MHz Turbo Core V2 microprocessor
- 576KB of memory on board
- Hand micro-shake smoothing function
- 1.8m Braided USB Cable
In short, I cried and

Mouse through the eyes of a hacker
2011
Pentragers from Netragard. Their note on this. They glued the teensy microcontroller with tape and that's it. I inserted a flash drive / mouse - after 60 seconds you are hacked. If there is a directive not to connect unfamiliar flash drives to the computer, then no one forbade connecting the mouse to the computer.
Netragard’s detailed attack report is published as a result of a recent U.S. Department of Homeland Security study that found that 60% of employees who discovered drives or USB sticks in the parking lots of government buildings and private contractors immediately connected them to their computers.

Logitech in 2009 stated: “Since the displacements of a mouse would not give any useful information to a hacker, the mouse reports are not encrypted.”

Intercepting data on the mouse path on the screen opens up the possibility for a “prediction attack” (prediction-based attacks) to predict where the victim will click on the virtual keyboard. The password accuracy is 95%.
Here Kaspersky Lab kindly offers a virtual keyboard :
And here is the HSBC bank keyboard :
The authors of the article argue that the vulnerabilities of wireless mice are clearly underestimated and ignored by manufacturers and call for paying attention to user safety.
Well, we'll wait for the paranoid mouse with an encrypted channel.

Here's what's inside a regular ball mouse:
For me, it was the discovery that optical sensors are used in a ball mouse.
What is inside this mouse here I’m even afraid to imagine:
It’s a pity to saw the mouse in half, so I wanted to unscrew it humanly. But it wasn’t there, the cog-bolts are not visible at all.
There was an idea that now they do not use bolts and I tried to pick it with a screwdriver. Did not work out. I began to search further - I found them under the overlays.
As it turned out - not all. But the screwdriver completed its work and the mouse with a crunch, but the
insidious bolt was opened hid under the sticker
LED wheel illumination. The mouse is simply crammed with LEDs and light guide pads. It looks cool, especially in the dark. The girls are thrilled.

User retention has become relevant for mice. Use our product a lot - get a trophy. They are given for mileage / clicks / scrolls - that is, simply for the use of the mouse itself.
A bit of history
XEROX chip for motion detection.
The first optical mice appeared in 1980, at MIT and Xerox, one of them worked in the IR, the other in the visible spectrum. The mat was one of a special composition for IR on metal, and the other was printed on paper. The mice had a different algorithm - one coordinate grid was attached to the rug and it went crazy if the rug was turned, the second took measurements relative to itself.
The first laser appeared in 1998 in the dungeons of Sun Microsystems, and Logitech released the MX1000 in 2004. Using a laser gave mice extra positioning accuracy, responsiveness and the ability to use on many different surfaces.
A little later, Logitech upgraded the system so that you can use the mouse on transparent surfaces: The
light beam is directed perpendicular to the surface, which eliminates distortion on transparent surfaces
Interesting instances of homemade mice
Inquisitive minds are not asleep and constantly think how to gash their supermouse.
Project with Kickstarter . The mouse reads the parameters - like heart rate and skin resistance - to reveal the most cold-blooded Jedi.

A hacker reads a fairy tale to his grandson:
- "... he began to click a goldfish ..."
- Grandfather, why a fish?
- And so, my friend, there were no mice then.
