In the next episode, we will be destroying an HP Keyboard that came along with this mouse: Lets turn out attention towards the back of the mouse, where it seems there is a heat sink or something that’s covering some chip. This is the brain of the mouse. It can often also be used as a third mouse button by pressing on it. It obviously is meant to plug into the HP keyboard

The cord of this mouse is particularly short, under 3 feet [about 70cm].
If we were interested in cleaning the mouse, we would wash the ball, etc. There are light-emitting diodes and light detecting diodes called photodiodes.
Logitehc is the brain of the mouse. The large center wheel also operates on the same principle, but the LED is a bit bigger: It was not until the release of the best-selling iMac in that USB became widespread. Real optical systems are complex and practical difficulties often increase the distance between distinguishable point sources.
The chip it is covering is a Logitech microcontroller. Resolution depends on the distance between two distinguishable radiating points.
In the next episode, we will be destroying an HP Keyboard that came along with this mouse: Unfortunately for the mouse, we don’t want to clean it. The one and only tool we will be using is a trusty “4 in 1” screw driver.

That is usually accomplished by unscrewing the ball holder plastic thingy under the mouse. Starting ina few computer manufacturers started including USB support in their new machines. It is used, as the name suggests, for scrolling. It is also based on LEDs.
The sections below describe the theoretical estimates of resolution, but the real values may differ. It is normally located between the left and right mouse buttons. There are 2 pairs of these, one for X-axis, and one for Y-axis.
The wheel is often – but not always – engineered with detents to turn in discrete steps, rather than continuously as an analog axis, to allow the operator to more m-u4b8 intuit how far they are scrolling. Next step is to unscrew the one and only screw that’s holding this thing together. In low-contrast systems, the resolution may be much lower than predicted by the theory outlined below.
A scroll wheel or mouse wheel is a hard plastic or rubbery disc the “wheel” on a computer mouse logitecch is perpendicular to the mouse surface. We can now just pull the pieces apart Movement is detected by sensing changes in reflected light, rather than by interpreting the motion of a rolling sphere. It obviously is meant to plug into the HP keyboard The first step in breaking or cleaning a m-ub4 mouse is to take out the ball. The results below are based on mathematical models of Airy logltech, which assumes an adequate level of contrast.
It can often also be used as a third mouse button by pressing on it.

We want to destroy it. A single USB port can be used to connect up to peripheral devices, such as mice, modems, and keyboards. The mouse originally came with an HP Pavilion PC, and was never used was replaced on day one by a Microsoft IntelliMouse Explorer, which will also be destroyed in later episodes. When the wheel moves, the diodes detect these slits.

These are set side by side, separated by a wheel with slits. This is essentially a Logitech mouse with an HP cover on it. USB also supports Plug-and-Play installation and hot plugging.
We’ve accomplished our goal of turning a perfectly good mouse into a pile of garbage:
